Skil, Likely Leveraging EGO Tech and Know-How, Launches PWRCore 40V Cordless…

Skil, Likely Leveraging EGO Tech and Know-How, Launches PWRCore 40V Cordless Outdoor Power Tool Lineup

Skil has launched a new line of PWRCore 40V cordless power tools.

Why should you care? Well, Skil’s parent company is Chervon, which is also parent company to the hugely successful EGO brand of cordless outdoor power tools. EGO has come out with some truly amazing tools and tech in recent years and have grown to be quite popular.

So, it’s my assumption that the same folks that designed and engineered EGO’s 56V cordless outdoor power tools have put their efforts towards these new Skil 40V cordless outdoor power tools. Skil’s system operates at a lower voltage, and the tools appear to be a bit more affordable than EGO’s.

In my mind, I’m seeing these Skil tools as “EGO Lite,” and hopefully that’s how they’ll end up performing.

All of the new Skil PWRCore 40V cordless power tools look to feature brushless motor tech.

Shown above is the PWRCore 40V 5.0Ah battery, with each cell said to be surrounded by temperature management material to keep the battery cool and powering on. (EGO Batteries feature similar tech.)

Skil says that their battery tech provides for 25% longer runtime and 2X battery life.

Skil’s new 40V charger has an Auto PWRJump feature, which can charge the 5.0Ah battery up to 30% capacity in only 30 minutes. This lets you take a short break and get some final work done without much delay.

If you’re using the 2.5Ah battery, the Auto PWRJump feature gets you to 30% charge capacity in just 15 minutes.

At this time, there are 6 tools included in the launch, and they’re only available in kit format right now. It’s unknown as to when Skil might launch bare tool versions of their new cordless offerings. In addition to the 6 kits there is also a blower and trimmer combo kit. Replacement batteries and additional chargers are also available at launch.

Skil PWRCore 40V Blower Kit – BL4713-10

The new Skil PWRCore 40V leaf blower is kitted with a 2.5Ah battery and charger, and features a turbine fan that can deliver up to 500 CFM of airflow, variable speed trigger, and a PowerBoost feature helps to clear heavier leaves and debris.

Skil PWRCore 40V String Trimmer Kit – LT4818-10

The new 14″ string trimmer is kitted with a 2.5Ah battery and charger. It features a 14″ cutting swath, and a dual line bump-feed and twist-to-load cutter head.

It works with 0.080″ twisted line. Skil doesn’t specify the cutting speed, but says that the motor delivers “a staggering 1200 watt output.”

Skil PWRCore 40V String Trimmer and Blower Kit – CB7478-10

There’s a single combo kit available at this time – a string trimmer and blower kit, for users who want to buy into the system and get both right away. We might see additional combo kits later in the season, but that’s hard to predict.

Skil PWRCore 40V Hedge Trimmer Kit – HT4221-10

The new 24″ hedge trimmer, kitted with a 2.5Ah battery and charger, has dual action hardened steel blades and cuts at a speed of 3000 strokes per minute.

We know that EGO’s 56V 24″ and 3000 SPM hedge trimmer can cut shrubs and branches up to 3/4″ thick. Skil’s 40V hedge trimmer has a similar maximum cutting capacity of 19 mm, which is ~3/4″.

Skil PWRCORE 40V Chainsaw Kit – CS4555-10

The new 14″ chainsaw, also kitted with a 2.5Ah battery, features tool-less chain tensioning, auto-lubrication, and an anti-kickback brake.

skil, likely, leveraging, tech, know-how

Replacement 14″ bars and chains look to be available at launch.

Skil PWRCore 40V Self-Propelled Mower Kit – SM4910-10

The new Skil 40V self-propelled mower features a 20″ cutting capacity and deck size, mulching, side discharge, and rear discharge modes, 60L collector capacity, and 7 cutting height settings from 1/4″ to 4″.

It has a push-button start and a folding and telescoping handle that allows for vertical storage.

The mower is kitted with a 5Ah battery and 150W charger.

Skil PWRCore 40V Push Mower Kit – PM4910-10

Skil is also launching a new push mower, and from what I can tell, it’s identical in specs and functionality to the self-propelled mower, except for the lack of motorized wheels. The wheels on this mower appear to be larger – at least at the front – which should help with manual maneuverability.

This mower is also kitted with a 5.0Ah battery and 150W charger.

Batteries and Charging Time

These charging rates are with the standard 150W charger (SC5364-00).

Pricing and Availability

At the time of this posting, it looks like Acme Tools has the tools at MSRP pricing, which will be quoted below, and Amazon has most of them at randomly lower pricing. At this time it looks like the tools are expected to start shipping in April or May.

The first thing that confuses me – and might bother me a little – is the “Auto PWRJump” feature, which charges a 2.5Ah battery from 0 to 30% in 15 minutes, and charges a 5.0Ah battery from 0 to 30% in 30 minutes.

I had to dig a little to find the SKU for the replacement charger, and only there does it say that the 2.5Ah battery fully charges in 60 minutes, and the 5.0Ah battery in 120 minutes.

Now, those are decent charging times – pretty fast actually. I don’t doubt that this is made possible thanks to the cooling wrap around each battery cell that keeps things cool and high-performing during use as well as charging.

But what’s the point in marketing the system’s Auto PWRJump feature if all it means is that you get 30% charging in 25% the time it takes for a full charge? That’s not surprising, since charging curves aren’t linear – it takes less time to charge a depleted battery than to top off a partially or nearly fully-charged one.

Oh, I see – Auto PWRJump. This is why there’s no mention of a PWRJump feature, button, or activation in the online user manual – because it’s automatic.

If a battery and charger don’t have a specific boosting or quick-charge function, why not simply market the 0-30% charging time without giving it a fancy name like Auto PWRJump.

That little peeve aside – as I don’t like that I was led to believe there was some kind of quick-boost charging function, which Chervon has built into some chargers before – I think that Skil is launching a solid line of cordless outdoor power tools.

Actually, I have very little doubt that these tools will perform well, although I’m known to be overly optimistic at times. EGO has come out with some excellent cordless outdoor power tools. With this Skil launch, I’m sure that Chervon leveraged their years of know-how and advancements.

Sure, these tools are less expensive then EGO tools, and that might mean lower performance, but the specs so far seem fair and balanced.

I really like EGO’s 15″ carbon fiber shaft string trimmer. At the time of this posting, it’s 229 via Home Depot, kitted with a 2.5Ah battery and charger. Skil’s trimmer is a 14″ trimmer, and it uses thinner line – 0.080″ vs. 0.095″. With that in mind, and the smaller battery (40V vs. 56V), the 180 kit price of the Skil seems proportionate.

With the Skil trimmer, you still get an easy twist-to-load bump-feed cutter head.

The biggest hurdle for Skil, in my opinion, is in how they market the new PWRCore 40V cordless tool lineup. Skil’s PWRCore 12V and 20V cordless power tool lines have expanded, but I think they need greater visibility.

Here, there’s a brand new line of Skil PWRCore 40V outdoor power tools, and I only learned about it from one of my “check to see if there’s something new on Amazon” searches. There are tools up on Skil’s website, Acme Tools, and Amazon, but no press releases, no launch announcements, nothing.

But the biggest problem is in retailer support.

Home Depot marketed EGO very heavily, and I believe that’s what boosted the brand into the leadership spot in the cordless outdoor power tool market, or at least the consumer OPE market. EGO sprung forward, and while other consumer brands have been working on their cordless lawn, garden, landscaping, and other outdoor cordless power tool offerings, EGO seems to be way ahead in performance, popularity, and innovation.

Skil might very well have the potential to be a leader in the 36V to 40V cordless outdoor power tool market, despite the late start. But, they need support to get there, which means spending money on advertising (hey – we’ve got some open spots and opportunities), but also coordinating with retailers on promotions and emphasized placements.

Lowe’s is likely FOCUS on promoting Craftsman cordless outdoor power tools. Home Depot will likely continue promoting EGO and Ryobi at the consumer level, and brands such as DeWALT, Makita, and Milwaukee for pros and consumers with deeper budgets.

Which retailers are going to emphasize Skil? Amazon? Are sponsored placements going to be enough? On a platform like Amazon’s, Skil will have competitors such as Greenworks to contend with, and also brands such as Worx, and even Black Decker. Amazon also offers Craftsman V60 cordless power tools, and I’m sure there will be coordinated marketing efforts as there were last year.

I’m optimistic about Skil’s new 40V cordless outdoor power tools, but I’m worried about how well the line will fare against more visible competitors. We’ve seen expansion in PWRCore 12V and 20V product lines, and so maybe Chervon will have the momentum to make Skil a household name (again?).

Right now, you can order a Craftsman V20 string trimmer kit (13″, 0.080″ line) for 139 via Amazon, or a V60 kit (15″, 0.095″) for ~182 via Amazon. Greenworks has a 12″ 0.080″ trimmer kit for 180. Skil’s 40V trimmer seems like a better buy than Greenworks’, and its intro price of 161 at Amazon is lower than the presumed MSRP of 180. But does it have enough to compete with Craftsman’s returning clout and market share?

The tools look decent, but the fact remains that I felt compelled to mention Skil’s sibling brand, EGO, in the post title to ensure that it caught enough readers’ interest to justify the time and effort of a detailed news post. That sentiment, that I didn’t think enough of you would be interested in the post if I only mentioned Skil in the title and left out their relationship to EGO, highlights the problem.

That all said, I am quite optimistic about the new tools. Skil has their work cut out for them in raising brand visibility and familiarity, but fortunately I have near-zero concerns about the quality and performance of these tools – this is Chervon’s specialty.

gardening tool manufacturers are opting for battery power over fuel or electric, and today’s string trimmers are a case in point. We tested these eco-friendly yard maintenance devices to help consumers make the right purchase for their property.

We may earn revenue from the products available on this page and participate in affiliate programs.

Handy outdoor power tools make quick work of tackling overgrown weeds and grass, giving the yard a tidy look and trimming hedges and shrubs. We put battery-powered trimmers through their paces on several grass or weed types to see how well they ran and cut, ultimately arriving at this list of the best battery trimmers.

For ensuring a polished look to a lawn, the best string trimmer is a great investment. These yard-care tools spin a cutting head loaded with nylon string (instead of a fixed blade) to cleanly trim the grass at the edge of a lawn or mow down weedy areas. Though gas and electric models once dominated, new and improved battery-powered versions don’t require mixing fuel or storing gasoline like gas string trimmers do, nor are they limited by the length of an extension cord, like corded electric string trimmers are.

Some battery trimmers are better suited to different-size yards, users, and budgets. So we could help consumers make the right choice, we tested some of the most popular string trimmers to find out how they perform under real-world conditions. To qualify as a top pick, a string trimmer should be durable, powerful, and easy to operate. The string line should exit the reel easily with no need for the user to constantly remove the reel cover and untangle the line.

The following battery-powered string trimmers are at the top of their class. Anyone looking to invest in a trimmer is likely to find one here to fit their landscaping needs.

How We Tested the Best Battery Trimmers

To truly test these battery-powered string trimmers, we started by assembling the tools and charging the batteries. Most trimmers arrived with the batteries about 25 percent charged right out of the box, but a full charge allowed us to gauge runtime at full power. Although some of the trimmers offer lower power settings that could extend runtime, we found that the lower settings simply made them less capable when it came to coarse weeds, so we ran them at full power for testing.

We put each trimmer through its paces in a variety of real-world scenarios: “clean” lawn grass, weedy grass, and natural areas featuring coarse, weedy seedlings and vines. To earn a spot in our lineup, the lightweight 20-volt (V) trimmers had to deliver a clean, crisp cut in both clean and weedy grass sections. In addition to trimming the grass zones, we used the 36V, 56V, and 80V models to cut through woody, viny growth in natural areas. Along with cutting power, we tested for battery runtime, maneuverability, and operator comfort and determined the best battery trimmer by category.

Our Top Picks

These reviews describe the key features of each cordless string trimmer and how the models performed in our backyard tests.

STIHL FSA 60 R 36V Battery Trimmer

It makes sense that the STIHL FSA 60 R would be a top performer in this test group. It comes from a brand with a long history of industry-leading outdoor power equipment. This string trimmer measures just over 66 inches long, weighs less than 10 pounds with the battery installed, and works for about 25 minutes per charge. The 36V 3.9 amp hours (Ah) battery charges in a little more than 2 hours.

The tough polymer material used for the motor housing and debris shield help keep the weight down. A few other standout features include a variable-speed throttle trigger, trigger interlock, battery retainer latch, EasySpool cutting head, bump guard, and hang loop. The trigger interlock and battery retainer latch prevent accidental startup. The variable trigger and EasySpool head improve operating efficiency by saving battery life and minimizing the time it takes to reload, respectively. The bump guard protects sensitive surfaces during close trimming, and the hang loop offers a convenient way to store the tool when not in use.

This is a great all-around pick for quarter- to a half-acre yards. The relatively short runtime of the STIHL FSA 60 R belies a very capable trimmer. In our tests it easily and cleanly sliced through all kinds of grass and weeds, including tough tree saplings up to about ¼ inch thick. The shorter runtime actually mattered less because the trimmer cut so well, and we moved at a faster pace than with some of the other trimmers with longer runtimes.

The other thing we noted here was the amazing level of operating comfort. The trimmer was fairly lightweight to begin with, but the weight was so well balanced—with just enough weight forward of the front handle to keep the head near ground level—that using it required significantly less effort than what was required of some of the other trimmers that weighed about the same. Also, vibration was minimal, so after trimming we had plenty of energy to keep working.

  • Weighs less than 10 pounds but easily powers through tough weeds
  • 25-minute runtime per charge for about 5,000 linear feet of trimming
  • Excellent balance to keep the head at ground level
  • EasySpool head, bump guard, variable-speed throttle, and accidental start protection
  • Smallish 13.8-inch cutting swath is on the small side for open spaces
  • 2-hour recharge time for battery is longer than that of some competitors

Get the STIHL battery trimmer at Ace Hardware or Blain’s Farm Fleet.

Ego ST1511T Power 15-Inch Powerload String Trimmer

Ego Power has made a name for itself in the outdoor power-equipment category by building an affordable battery-powered tool line that competes favorably against old-fashioned 2-cycle gas-powered equipment. The ST1511T 15-inch string trimmer proved to be powerful, clean, and quiet in testing. The 56V 2.5Ah lithium-ion battery delivers up to 45 minutes of runtime, with a recharging time of just 50 minutes. The bump-feed trimmer head comes preloaded with 0.095-inch trimmer line for more cutting force and less noise. Taller users will appreciate the straight shaft design, and the unit weighs in at just over 10 pounds.

In our tests, the Ego trimmer showed ample power to cut through everything in its path, including overgrown, weedy grass; privet seedlings; and honeysuckle vines. Its well-balanced design, with the heavy battery in back offset by the long, straight shaft, made it comfortable to work with and more agile than others we tested. Our only caveat: For seasonal yard cleanup or maintaining larger landscapes, the 45-minute maximum runtime may not be quite enough.

  • Auto-loading trimmer head reduces downtime while working
  • Adjustable telescoping straight shaft provides a custom fit for different users
  • Excellent power and runtime value at a moderate price point
  • Heavier than some with less forward weight to keep head down
  • Battery is bulkier than others, making the tool tiring to use over an extended period

Get the Ego Power battery trimmer at Amazon, Ace Hardware, or Lowe’s.

BlackDecker LST300 LBXR2020-OPE 20V String Trimmer

To give the yard a polished look without breaking the bank, consider the BlackDecker cordless string trimmer. It features a 12-inch cutting swath to cut down the corners and clean up the edges of small- to medium-size yards. An automatic feed spool means no more stopping to bump the tool when new string is needed. Two 20V lithium-ion batteries are included.

In our tests, this trimmer performed very well in weed-free grass and in weedy lawn areas. With a light weight of just 5.7 pounds, this trimmer is easy to handle without causing arm and shoulder fatigue. The short, straight shaft design is most comfortable for users under 5 feet 9 inches tall. We also liked that with a quick adjustment to the head, the trimmer becomes an edger to neaten up the grass along sidewalks and driveways. In all, we found this affordable tool a solid pick for small obstacle-free landscapes.

  • Pack includes 2 batteries for more runtime, less downtime
  • Automatic feed spool
  • Money- and space-saving design that both trims and edges
  • Battery recharges in just 45 minutes

Get the BlackDecker battery string trimmer at Amazon (with extra battery) or The Home Depot.

Skil PWRCore 40V Brushless Self-Propelled Mower

Makita XRU15PT1 36V LXT Brushless String Trimmer Kit

The Makita XRU15PT1 string trimmer is a premium option to keep the lawn and garden under control. It can handle large yards with enough power to tackle dense weed growth. This cordless string trimmer comes with four 18V 5.0Ah batteries so you’ll never run out of power. Shoppers can purchase this model as a kit that includes a dual battery charger and two sets of batteries, or as a “tool only” for those who already have items from the Makita 18V tool platform.

With a long, straight shaft and high-power cutting head, this 10.4-pound trimmer feels like a pro-quality tool. It was well balanced and articulate while trimming around shrubs and between obstacles. It had plenty of power to cut through tough vegetation. In our tests, it made nice clean cuts and crisp edges in the grassy areas and tore through weedy privet seedlings and honeysuckle vines without hesitation. It’s an excellent candidate to replace gas equipment for medium to large landscapes, though the price may be high for budget-minded shoppers.

skil, likely, leveraging, tech, know-how
  • Runtime is longer than charge time for ready-to-go fresh batteries
  • Includes a second set of batteries for extended work
  • Gas-like power and performance for tough trimming jobs
  • Expensive trimmer due to the high cost of batteries
  • Small debris guard allows some material close to operator
  • Stiff bump head required a hard strike to let out line

DeWALT DCST972X1 60V MAX 17-Inch String Trimmer Kit

When an established leader in pro-grade cordless hand tools enters the lawn-care category, shoppers will want to take note. The DeWALT 60V battery trimmer packs a heavy-duty brushless motor powered by a 60V 3Ah FlexVolt lithium battery that lets it tear through all kinds of tough weeds for at least 40 minutes per charge.

This attachment-capable trimmer comes equipped with a straight shaft and Rapid- loading adjustable spool. It uses.080-inch trimmer line to cut either a 15-inch or 17-inch swath. A safety switch in the grip prevents accidental starts. Users can select high or low power, depending on the project, and control the trimming RPM with a variable-speed trigger. The universal attachment feature lets owners replace the trimmer attachment with a variety of other tool heads, including an edger, hedge trimmer, pole saw, and more.

The DeWALT battery trimmer was one of the heaviest we tested, but also the most powerful. With the standard.080-inch trimmer line that came pre-spooled, this tool had no trouble cutting anything from grass to thin tree seedlings and even tough blackberry canes. In low-power mode it offered more cutting force than the high- power setting of most others we tested. In high range it beat all but the STIHL, which was about an even match in terms of pure power. To be honest, high power was too much for many of our applications, so we also tested thoroughly in low range. It ran about 40 minutes on high, and about 60 on low.

Other than the heavy weight, the only negative point we have to offer is the noise. The trimmer is loud to begin with, and when initially triggering or feathering the trigger it makes an even louder whine/whistle sound. Still, it’s a very impressive tool at a fair price for the power and runtime and a good choice for large properties or cleaning up overgrown areas.

  • Battery type: 60V 3Ah FlexVolt lithium ion
  • Runtime: 40 minutes
  • Weight: 12.95 pounds
  • Outstanding power for clearing overgrown weeds and brush
  • Works with.080-inch or.095-inch trimmer line for normal or heavy trimming
  • Excellent runtime of up to an hour for average grass trimming
  • Power head can run other landscaping tool attachments
  • Heavy weight of just under 13 pounds, but no shoulder strap
  • Longer battery charge time at 135 minutes
  • Noisy operation, especially when initially triggering

Get the DeWALT battery trimmer at Amazon, Ace Hardware, or The Home Depot.

BlackDecker LSTE525 20V MAX String Trimmer/Edger

Weighing just 8.8 pounds, this string trimmer is easy to carry, maneuver, and control with an adjustable handle and a safety trigger switch to prevent accidental starts. The 12-inch trimming radius is suitable for keeping the lawn properly maintained without damaging fencing, decks, trees, or other common yard obstacles.

This cordless string trimmer operates with a 20V battery that can last for up to 20 minutes, and a spare battery is included. For edging, simply turn the head and use the built-in wheel to balance as the trimmer string handles the task.

When we used the tool to trim weedy lawn grass patches and edge the curb and driveway, it made nice clean cuts and tracked well to make good straight edges. The shaft and handle adjusted to comfortably fit our 6-foot user. The tool is amazingly lightweight for the amount of power it offers, but the weight is mostly balanced to the front of the handle, and having to manually counterbalance it while working fatigued our tester. Though not built for heavily weed-infested yards, it has ample power and runtime to clean up curb lines, driveway edges, and otherwise maintain a smaller landscape.

  • Very lightweight and easy to carry
  • Handle is customizable to fit the size of user
  • Trimmer doubles as an edger with a simple turn of the head
  • Battery provides limited runtime, although a spare is included
  • Not enough power to tackle coarse, woody weeds
  • Weighted toward the front, which may cause user fatigue

Get the BlackDecker MAX battery trimmer/edger at The Home Depot or Tractor Supply Co.

Echo DSRM-2100 eFORCE 56V 16-Inch Battery Trimmer

A wide cutting swath, extended runtime, and powerful trimming ability make the Echo DSRM-2100 eFORCE battery trimmer an excellent choice for large yards. The straight-shaft trimmer is powered by a brushless motor and 56V 2.5Ah lithium battery for up to 56 minutes of powerful performance that rivals traditional 2-cycle trimmers. It cuts a 16-inch-wide swath to get the job done efficiently.

This battery trimmer weighs in at a comfortable 9.75 pounds, making it a relatively lightweight choice at this level of capability. It features battery-saving low/high power settings for different cutting conditions, a variable-speed trigger, and a cushioned handle grip for comfort. The Speed-Feed cutting head comes preloaded with.095 trimmer line and reloads quickly without disassembly.

The Echo eForce battery trimmer is an excellent value for large-property maintenance. In our tests, the cutting power seemed to be slightly less than that of the DeWALT and STIHL trimmers, but it was still very capable. In high-power mode we trimmed for about 40 minutes. But the better-than-average power and wider swath meant that in 40 minutes with the Echo, we were able to complete work that other trimmers would need an hour to accomplish. The noise level was good, and reloading was fast and easy.

skil, likely, leveraging, tech, know-how

This trimmer could have scored higher with improved balance. Although it is a lightweight trimmer overall, most of the weight is in the working end. The heavy cutting head forces the operator to compensate by lifting upward on the front handle and pushing downward on the rear handle while working. We tested with the 2.5Ah battery that comes standard. Working with the available 5Ah battery (sold separately) would rebalance the trimmer to some degree while doubling runtime and increasing overall weight.

  • Excellent price for this combination of power and runtime
  • Wide cutting swath and power performance for large properties
  • Rapid charging system charges the battery in less than 40 minutes

Get the Echo battery trimmer at The Home Depot or Acme Tools.

Worx WG163 20V Power Share GT 3.0 String Trimmer

Owners of small yards may find this lightweight string trimmer an excellent option. It weighs just 5.5 pounds and easily converts from a trimmer to an edging tool; a built-in wheel helps balance the tool while edging. A push-button feed system gives the ability to extend the trimmer string without bumping the 12-inch trimmer head or manually pulling additional string from the trimmer. It comes with two 20V batteries and a charger, and the battery lasts for up to 20 minutes on a full charge.

This Worx string trimmer tackled our grassy areas with ease, both the weedy and weed-free zones, but it wasn’t as capable on rough areas. We were particularly impressed by the edger function, which we found comfortable and well balanced thanks to the 90-degree shaft-rotation capability. The adjustable trimmer head and upper handle let us customize the working angle, but the process of doing so proved clunky. We had to reach down and turn a rather stiff knob at the connection point between the shaft and cutting head to unlock and relock the angle for each adjustment.

  • Battery provides limited runtime, although a second battery is included
  • Head-tilt adjustment is somewhat awkward and clunky
  • Relatively long 60-minute charging time for 20 minutes of runtime

Husqvarna 320iL 40V Battery String Trimmer

One limiting factor of most string trimmers is the cutting head’s direction of rotation; it matters more than one might think. The direction of rotation determines where the clippings will go, and in some situations, how the user should grip the trimmer. The Husqvarna 320iL 40V battery trimmer offers a solution, thanks to its dual-direction cutting head. At the touch of a button, we could change from clockwise to counterclockwise rotation and back, without changing grip on the handles.

This straight-shaft trimmer is powered by an efficient brushless motor and 40V 4Ah battery that drives about 45 minutes of runtime per charge. It features a Rapid-load cutting head that comes prespooled with.080 trimmer line and cuts a 16-inch swath. Low-vibration technology improves operator comfort, and the machine weighs in at just over 10 pounds with the battery.

The Husqvarna 320iL ranked near the top of the test group in terms of user comfort and quiet operation, but its power was somewhat underwhelming after the big showing from the STIHL and DeWALT trimmers. We were super impressed with the dual-direction feature. It allowed us to use the trimmer right- or left-handed, and we could safely trim curb lines from either direction without standing in the street. On high-power mode the trimmer performed lawn-trimming duty superbly, but in heavy weeds and natural areas it could not keep up with the more powerful trimmers.

Anyone not interested in going off the beaten path might still do well to consider this trimmer. Its balance is impeccable, rivaling the STIHL in comfort even though it’s a fraction of a pound heavier. And for quiet operation, this one takes the gold medal. The only real question regarding comfort and control was, why so many buttons? Its four thumb-operated buttons control on/off, high/low power, clockwise rotation, and counterclockwise rotation.

  • Dual-direction trimmer head leaves clippings where desired
  • Excellent balance for comfortable extended use and less fatigue
  • Among the quietest of the trimmers we tested

Worx WG170 20V Power Share Revolution String Trimmer

While plenty of string trimmers also function as edgers, we found this model to have the best dual-function design. At the push of a button, the trimming head on the Worx WG170 Revolution trimmer converts to an edger that rolls easily along the edge of a sidewalk or driveway. The head tilts up to 90 degrees, so it is easy to reach weeds on slopes while standing comfortably.

The trimmer comes with two batteries plus a charger and three extra spools of trimmer line. The string trimmer also boasts a handy spacer guard that keeps it from bumping into plants, and the shaft adjusts to suit taller or shorter users. It cuts a 12-inch swath and operates on a 20V lithium-ion battery. We tested the tool with the 2Ah battery, but it also comes with a 4Ah battery at some retailers.

In our yard, this trimmer cut through and created a crisp edge on both weedless and weedy lawn areas. We really liked the easy adjustable feature on the trimmer head: A twist lock holds it in just the right position, up to 90 degrees, for a customized working angle for users of different heights. Also, the batteries are interchangeable with those of many other Worx 20V cordless tools.

  • Adjustable upper handle to accommodate users of different sizes
  • Trimmer head converts to an edger for use along sidewalks or driveways
  • Comes with 2 batteries to make up for shorter runtime
  • Requires a relatively long charging time
  • Trimmer feels underpowered for tackling coarse, heavy weeds
  • Only 20 minutes of runtime per charge

Greenworks Pro 80V 16-Inch Cordless String Trimmer

The Greenworks Pro 80V trimmer is a quality tool that adapts to a variety of other functions with attachments such as a brush cutter. (However, attachments are sold separately.) The 2Ah battery provides up to 45 minutes of runtime and recharges in just 30 minutes. The brushless electric motor is efficient and quiet, providing plenty of torque to cut through heavy weeds without the noise and smell of a gas-powered unit.

In our test areas, the Greenworks Pro trimmer was powerful enough to cut through the toughest weeds and vines with ease. The heavy battery weighs the machine down toward the rear, but the included adjustable shoulder strap makes operation more comfortable. The battery is compatible with other Greenworks 80V tools. Just don’t get too excited about the variable-speed trigger: Although it’s intended to allow a gradual increase from “off” to “high” speed, we found the range of movement between the two to be minuscule; in effect, the trimmer is either “off” or “on.”

  • Battery type: 80V 2Ah lithium ion
  • Runtime: 45 minutes
  • Weight: 10.6 pounds without battery
  • Trimmer has a quiet, efficient brushless motor
  • The recharging time is only 30 minutes; runtime is 45 minutes
  • Gas-like power and performance without the noise and smell
  • Slight lag time between triggering and full power
  • The trimmer’s adjustable speed feature is difficult to use
  • Weight is balanced toward the rear, but shoulder strap helps

What to Consider When Choosing a Battery Trimmer

When shopping for string trimmers, also known as weed eaters, keep in mind yard size, how often the tool will be used, and the height and strength of the primary user. The following key considerations will help in selection.

Trim Width

Trim width, also called swath width, indicates how wide a path the trimmer will cut through weeds in a single pass. Many models on the market today feature swath widths of 10 to 18 inches. The wider the width, the more power the trimmer must have, which often means the tool will be heavier because it will require a larger, more powerful battery.

Battery Type

Running a string trimmer requires a hefty dose of power. Though most of today’s trimmers run on rechargeable lithium-ion (Li-ion) batteries, a few accept nickel cadmium (NiCad) batteries. Li-ion batteries are more powerful, but NiCad batteries are less expensive (an average of 70 to 125 less). Li-ion batteries also are smaller, hold a charge longer, and provide full power throughout the discharge cycle.

NiCad batteries suffer from “memory effect,” meaning if the battery is used before it has fully charged—or if it’s recharged before its power depletes—it will “remember” the earlier charge level and won’t hold a longer charge in the future. If choosing a trimmer that has a NiCad battery, let it charge fully before use and drain completely before charging. For most users, a string trimmer with a Li-ion battery will be the best choice.


Along with battery type, consider how much operating power the battery has, which is measured in volts. Today’s rechargeable string trimmer batteries average from 18 volts up to an average of 60 volts of power. powerful batteries at the high end often are intended for commercial use and can cost 200 or more per battery.

Some string trimmers in this category sell without a battery (or battery charger), which the user must purchase separately. This could be a cost-saving benefit for those who are adding to a same-brand, battery-compatible cordless tool collection, since the same battery will power multiple tools. However, it can be more convenient to purchase a kit with multiple batteries to have one on the charger while the other is in use.

Feed Type

The “feed” of a string trimmer indicates how the trimmer head releases additional trimmer line as it becomes frayed and broken during use. The standby is a bump feed where the user bumps the bottom of the trimmer (the area where the spool attaches) on the ground to release a few inches of fresh line.

Some newer models feature an auto-feed sensor that gauges the length of the strings and releases more when needed. Still others have a push button to release more line. Auto and button feeds eliminate the need to bump the spool, which can reduce the risk of damage if bumped too hard, but many commercial-type trimmers still use bump feed because it’s quick and easy.

Curved vs. Straight Shaft

Some string trimmers feature a straight shaft that runs from the handle to the cutting head, while other models feature a distinct curve in the lower shaft about two-thirds of the way down. Some users find curved-shaft trimmers to be easier to operate since the spool end already rests at a handy angle for weed whacking.

Straight-shaft trimmers often accommodate interchangeable tools, such as a tree trimmer head, which can be swapped out depending on the task at hand. In general, straight-shaft trimmers work better for users at least 6 feet tall, while shorter users will appreciate curved-shaft trimmers.


Battery-powered string trimmers have a distinct advantage over gas-powered trimmers when it comes to noise pollution. Gas-powered trimmers are moderately loud, emitting an average of 90 decibels (about as loud as a motorcycle passing by from 25 feet away). By contrast, a cordless string trimmer emits approximately 77 decibels, which is comparable to casual conversation.


Those who are still unsure about how to use a battery string trimmer may find the following answers to common questions about these tools helpful.

Q. Can a string trimmer cut weeds?

A string trimmer is used to cut and control weed growth around the home and garden. However, light-duty trimmers may have issues with very dense weed growth.

Q. Can you use a string trimmer to cut grass?

A string trimmer can be used to cut grass, though you need to be careful not to cut the grass too short while trying to keep the trimmer balanced. It isn’t the easiest way to cut the grass, but it is possible.

Q. Can you edge with a string trimmer?

Yes, a string trimmer can be used for edging the garden, driveway, walkway, or sidewalk. If you have a large yard, it may be better to invest in a separate edging tool.

Q. How many volts should be in a trimmer?

String trimmer batteries average from 18 volts up to 80 volts. Typically, the higher the voltage, the longer the battery life.

Q. How do you edge a lawn with a string trimmer?

Hold the string trimmer perpendicular to the lawn to keep the cut even. Position the head about 4 inches off the soil so the string has space to rotate. The string should rotate and cut through the grass and dirt. As you move along the desired borders, keep the head balanced and even. Clean up the cut grass and dirt to finish the job.
