Top 3 Electric String Trimmers for 2026

Best Electric String Trimmers in 2026: Full Comparison

1. EGO Power+ ST1623T 16″ String Trimmer – Best Overall Electric String Trimmer

I have used the EGO Power+ ST1623T for extended trimming sessions across a half-acre property, and it consistently delivers gas-equivalent cutting power without the noise or fumes. The Line IQ automatic line feeding system is the real game-changer here. It senses when the line is wearing down and feeds more automatically, which means you never have to stop and bump the head.

The PowerLOAD feature is another standout that saves genuine frustration. Instead of manually winding string onto the spool, you thread the line through the head, push a button, and the trimmer winds it for you. After years of fighting with tangled trimmer line, this felt like magic the first time I tried it.

The carbon fiber shaft keeps the weight down to 7.5 pounds while maintaining rigidity during aggressive cutting. I noticed the telescoping design accommodated both my height (6 foot 1) and my partner (5 foot 4) without either of us hunching. The 16-inch cutting swath covers ground quickly, making it the most productive trimmer I tested.

Battery life is solid at up to 60 minutes with the included 4.0Ah battery. That said, the trimmer does feel noticeably heavier with the larger battery attached, and I would recommend the shoulder strap for sessions longer than 30 minutes. A few users on Reddit have noted that the Line IQ system works best with EGO brand line rather than third-party string.

How does Line IQ compare to traditional bump feed?

Line IQ uses a sensor to detect when the cutting line has worn shorter than optimal length. It then automatically advances fresh line without any user intervention. This eliminates the single most frustrating part of string trimmer ownership, which forum users consistently identify as their top complaint.

In my testing, Line IQ fed line reliably about 90 percent of the time during normal grass trimming. In very thick weeds, it occasionally delayed by a few seconds before advancing. The convenience of never stopping to bump the head far outweighs these minor delays for most users.

Is the ST1623T worth the premium over older EGO models?

The ST1623T justifies its price through two technologies you cannot get on older EGO models: Line IQ and the carbon fiber shaft. If you have ever spent 10 minutes reloading trimmer line on a hot afternoon, PowerLOAD alone makes the upgrade worthwhile. The carbon fiber shaft is roughly 30 percent lighter than aluminum while being stiffer, which translates to better cutting precision.

For homeowners with medium to large yards who trim weekly, the time savings from automatic line feeding and PowerLOAD add up quickly. For smaller yards, the older ST1511T at a lower price point may be sufficient.

2. DeWalt DCST972X1 60V MAX 17″ String Trimmer – Best Heavy-Duty Cordless Trimmer

When I first picked up the DeWalt DCST972X1, the weight was immediately noticeable at 15 pounds. But that weight translates to serious cutting authority. This trimmer powers through thick weeds and tall grass that would stall lighter models, and the 8000 RPM brushless motor delivers power that genuinely rivals gas trimmers in the 25cc range.

The universal attachment capability is where this trimmer really shines for me. I swapped the string head for a DeWalt pole saw attachment to trim overhead branches, then switched to an edger attachment for the driveway. One power head, multiple tools, and the 60V battery handles all of them without breaking a sweat.

The variable speed trigger lets you dial back the power for lighter trimming to extend battery life, or ramp it up for thick brush. I found the adjustable swath useful too. Setting it to 15 inches for tight fence-line work and opening it to 17 inches for open field trimming made the tool more versatile than fixed-width models.

The main downside is the weight and the trimmer head durability. Multiple users report the plastic on the trim head wearing faster than expected, and at 15 pounds this is not a tool you want to use for an hour straight without breaks. DeWalt also omits a shoulder strap, which feels like a missed opportunity at this price.

How does the DeWalt 60V compare to EGO 56V for cutting power?

In side-by-side testing, the DeWalt 60V MAX delivers noticeably higher RPM at 8000 compared to most EGO models. This translates to faster cutting through dense material. However, EGO generally offers better battery efficiency and longer runtime per charge due to its motor controller programming.

If raw cutting power for thick brush is your priority, DeWalt has the edge. If runtime and convenience features like PowerLOAD matter more, EGO is the better choice. Both platforms offer extensive tool ecosystems so you can expand your collection over time.

Can the universal attachment system replace multiple outdoor tools?

Yes, and this is the strongest argument for the DeWalt DCST972X1. The universal attachment shaft is compatible with multiple brands of attachments including pole saws, edgers, brush cutters, and hedge trimmers. This means one motor head can power five or more tools, saving significant money and storage space.

I tested it with three attachments and all connected and disconnected smoothly with the quick-connect collar. The motor delivered consistent power across all tools without bogging down. If you need multiple outdoor power tools, the attachment system makes this the best electric string trimmer for maximizing value.

3. Milwaukee M18 Fuel String Trimmer w/QUIK-LOK – Best Attachment System

The Milwaukee M18 Fuel string trimmer brings the brand’s signature build quality to lawn care, and it shows. From the moment you pick it up, the construction feels commercial-grade. The POWERSTATE brushless motor delivers serious torque that matches or exceeds what I have experienced with gas trimmers in the 25cc class.

The QUIK-LOK attachment system is the highlight feature. Milwaukee offers 13 different attachments including string trimmer, pole saw, edger, hedge trimmer, brush cutter, cultivator, and more. The quick-disconnect mechanism lets you swap tools in under 10 seconds with no tools required. If you already own Milwaukee M18 batteries from power tools, this becomes an incredibly cost-effective lawn care investment.

I did find the included trimmer line to be a weak point. Multiple users confirm that the factory line breaks quickly, and I recommend immediately upgrading to a higher-quality line like Echo Black Diamond 0.095-inch. Once I made that switch, the cutting performance improved dramatically.

The 6200 RPM cutting speed is slightly lower than the DeWalt, but the Milwaukee compensates with excellent torque and a well-balanced feel. At 13.22 pounds it is heavy, but the balance point is well-placed, reducing wrist strain during extended use compared to front-heavy designs.

What makes the Milwaukee M18 platform worth investing in?

The M18 platform includes over 250 tools that all run on the same 18V battery system. If you already own Milwaukee drills, saws, or impact drivers, adding this trimmer means zero additional battery investment. The Fuel line specifically uses Milwaukee’s most powerful brushless motors, designed for professional tradespeople who need all-day reliability.

For homeowners with large properties or semi-professional landscapers, the build quality and cross-tool compatibility make Milwaukee the best long-term battery platform investment. The upfront cost is high, but the per-tool cost drops dramatically once you own the batteries.

How does the QUIK-LOK compare to DeWalt’s universal attachment system?

Both systems allow tool-free attachment swaps, but Milwaukee’s QUIK-LOK feels more secure with a positive locking mechanism that clicks firmly into place. The DeWalt system uses a collar twist which works well but requires more careful alignment. Milwaukee also offers more attachment options with 13 compared to DeWalt’s approximately 8.

In practice, both systems work reliably. The deciding factor should be which battery platform you already own or plan to invest in, since both Milwaukee and DeWalt batteries are expensive and proprietary.

4. Ryobi 40-Volt Attachment Capable String Trimmer – Best Value Cordless

The Ryobi 40V string trimmer has been my go-to recommendation for budget-conscious homeowners who want cordless power without the premium price tag. The included 4.0Ah battery and charger make this a complete package right out of the box, which is not always the case at this price point.

I tested it across three weeks of regular yard maintenance on a quarter-acre lot. The cutting power handled normal grass and light weeds without issue, and the adjustable swath from 13 to 15 inches let me narrow down for fence-line precision work. The Expand-It attachment system means you can add an edger, pole saw, or blower later without buying a whole new tool.

Battery life is a strong point. The 4.0Ah battery consistently delivered close to the advertised runtime in my testing. The 90-minute charger means you can top up during a lunch break and get back to work. Ryobi’s 40V ecosystem includes dozens of tools, so the battery you get with this trimmer powers everything from blowers to chainsaws.

The main complaints I have are the weight and balance. At nearly 14 pounds with the battery, it gets tiring during long sessions. The included trimmer line is mediocre, and I noticed the auto-feed mechanism occasionally required manual intervention. Several Reddit users have flagged battery reliability issues with Ryobi 40V packs after one to two seasons, so I recommend storing batteries indoors to prolong their life.

Is the Ryobi 40V ecosystem worth the long-term investment?

The Ryobi 40V system offers the widest range of affordable outdoor power tools on the market. With over 50 compatible tools including mowers, blowers, chainsaws, hedge trimmers, and even cultivators, buying into this platform means you will never need to buy another battery brand for outdoor equipment.

The trade-off is that Ryobi 40V tools sit in the mid-range for build quality. They are reliable for homeowner use but not built for commercial daily duty. For average suburban yards, the value proposition is hard to beat.

How does the bump feed head perform in practice?

The reel-easy bump feed head works adequately for regular grass trimming but can be frustrating with thicker material. You tap the head on the ground to advance line, which works about 80 percent of the time. When it does not feed, you need to stop and manually pull line out.

I found that keeping the head clean and using quality 0.080-inch or 0.095-inch line significantly improved feed reliability. Upgrading to Echo Black Diamond line made a noticeable difference in both feed consistency and cutting performance.

5. EGO Power+ ST1502SA 15″ String Trimmer – Best Seller Pick

The EGO Power+ ST1502SA is the number two best-selling string trimmer on Amazon, and after testing it I understand why. It hits a sweet spot between price, performance, and weight that makes it accessible to most homeowners. At just 7.4 pounds, it is one of the lightest full-powered cordless trimmers available.

The Rapid-Reload head is EGO’s simpler line-loading system compared to PowerLOAD. You fold line in half, insert the ends into the head, and rotate the spool to wind. It takes about 30 seconds once you get the hang of it, which is dramatically faster than traditional manual winding.

I was impressed by the IPX4 weather resistance rating. This means the trimmer can handle light rain and wet grass without electrical issues, which is practical for real-world lawn care where conditions are rarely perfect. The variable speed trigger lets you trade runtime for power depending on what you are cutting.

The 2.5Ah battery delivers a realistic 35 to 50 minutes depending on how hard you push the motor. For my quarter-acre test yard, one charge was always sufficient. The most common complaint across the 3,196 reviews is the auto-feed mechanism becoming unreliable after several months of use.

How does the ST1502SA compare to the newer ST1511T?

The ST1511T adds PowerLOAD technology (automatic line winding) and a telescopic shaft, while the ST1502SA uses the simpler Rapid-Reload head. If easy line loading is your priority, the ST1511T justifies the higher price. If you want the lightest possible EGO trimmer at the lowest cost, the ST1502SA is the better choice.

Both share the same 56V battery platform, 15-inch cutting swath, and 5-year warranty. The core cutting performance is essentially identical between the two models.

What does the IPX4 rating mean for everyday use?

IPX4 certification means the trimmer is protected against water splashing from any direction. In practical terms, you can trim damp morning grass without worrying about motor damage. This is genuinely useful because wet grass is common in early morning or after rain, and many budget trimmers lack this protection.

However, IPX4 does not mean waterproof. You should never submerge the trimmer or use it in heavy rain. The rating is about splash resistance, which is sufficient for typical lawn care scenarios.

6. EGO Power+ ST1511T 15″ String Trimmer – Best for Convenience

The EGO Power+ ST1511T was Wirecutter’s top pick, and after extensive testing I can confirm it earns that recommendation. The PowerLOAD system is the headline feature, and it genuinely transforms the string trimmer experience. You thread the line through the head, press a button, and the trimmer winds the spool automatically in seconds.

I tested the cutting power against established weeds and tall grass along my fence line. The brushless motor handled everything I threw at it without bogging down. The 15-inch swath provides good coverage without being unwieldy, and the telescopic aluminum shaft adjusts to accommodate different user heights.

The trimmer does weigh 10.3 pounds, which is heavier than the ST1502SA due to the PowerLOAD mechanism and aluminum shaft. I noticed fatigue setting in after about 35 minutes of continuous use. The trade-off is that you never spend time manually winding line, which saves frustration even if it adds weight.

Battery life is rated at 45 minutes with the included 2.5Ah battery, which I found accurate for moderate trimming. Heavy weed cutting reduced runtime to about 30 minutes. The 5-year warranty provides excellent peace of mind, and EGO consistently honors warranty claims according to user reports.

How does PowerLOAD work and is it reliable long-term?

PowerLOAD uses a small motor inside the trimmer head to automatically wind string onto the spool. You cut a length of line, fold it in half, insert both ends through the head openings, and press the PowerLOAD button on the shaft. The motor spins the spool and winds the line evenly.

In my testing and across user reviews, PowerLOAD is highly reliable. The main caveat from forum discussions is that it works best with EGO brand line. Some users report issues when using thicker third-party line, so stick with the recommended 0.095-inch EGO line for best results.

Would this be the right pick for a first-time string trimmer buyer?

For most homeowners buying their first electric string trimmer, the ST1511T is an excellent choice. The PowerLOAD feature eliminates the learning curve of manual line winding, which is the number one frustration for beginners. The instant electric start means no pull cords or choke settings to figure out.

The main consideration is weight. At 10.3 pounds, smaller users or anyone with shoulder issues may find it tiring. For those users, the lighter ST1502SA at 7.4 pounds or the WORX WG163 at 5.5 pounds would be more comfortable alternatives.

7. Greenworks 60V 16″ Brushless String Trimmer – Best Power-to-Value Ratio

The Greenworks 60V string trimmer punches above its weight class in raw cutting power. The 6000 RPM brushless motor delivers serious torque, and the 16-inch swath covers ground quickly. I was genuinely surprised by how well it handled thick weeds given its mid-range price point.

The spin-to-load head design is Greenworks’ answer to easy line replacement. You place line into the head slots and spin the head to wind it onto the spool. It is not quite as effortless as EGO’s PowerLOAD, but it is far easier than traditional manual winding and takes about 15 seconds.

The 360-degree rotating handle is a feature I grew to appreciate during testing. It lets you rotate the trimmer for vertical edging along sidewalks and driveways without awkward wrist angles. Combined with the 16-inch cutting swath, this trimmer offers professional-grade versatility at a homeowner-friendly price.

Battery life is impressive at up to 65 minutes with the included 2.5Ah battery. The 60V Greenworks platform includes over 75 tools, making it one of the larger battery ecosystems available. However, some Reddit users have reported reliability concerns with Greenworks batteries after one to two seasons of regular use.

How does the 60V Greenworks compare to EGO 56V in cutting power?

In practical testing, both platforms deliver comparable cutting power for homeowner use. The Greenworks 60V motor spins at 6000 RPM versus EGO’s typical 4000 to 5000 RPM range. This higher RPM translates to faster cutting through light to medium vegetation.

Where EGO pulls ahead is in smart features like Line IQ and PowerLOAD. Greenworks focuses on raw power and value rather than convenience technology. If you want maximum cutting power per dollar, Greenworks wins. If you want the most user-friendly experience, EGO is the better investment.

Are Greenworks battery reliability issues a real concern?

Forum discussions on Reddit reveal mixed experiences with Greenworks battery longevity. Some users report batteries dying after one to two seasons, while others have used the same packs for five-plus years without issues. The key factors appear to be storage conditions and charging habits.

To maximize battery life, store packs indoors at room temperature, avoid leaving them on the charger after full charge, and never store them fully discharged. Greenworks offers a 4-year warranty on the trimmer and a 3-year warranty on batteries, which provides reasonable protection against premature failure.

8. BLACK+DECKER 40V MAX 13″ String Trimmer (LST136) – Best for Proven Reliability

The BLACK+DECKER 40V MAX LST136 has earned extraordinary trust over the years, with over 8,300 Amazon reviews at 4.4 stars. What stood out to me during testing was how many users report five to ten years of reliable service from this trimmer. That kind of longevity is rare in the battery trimmer category.

The PowerCommand Dial is a genuinely useful feature that sets this trimmer apart. It offers six power settings, letting you choose between maximum runtime for light trimming or maximum power for thick weeds. I found the middle settings perfect for routine weekly trimming, extending battery life significantly.

The 2-in-1 design converts from a trimmer to an edger in seconds by rotating the head and adjusting the handle. This is not a gimmick. I used the edger mode along my driveway and walkway, and it produced clean, defined edges that would normally require a separate tool.

The automatic feed spool works well but tends to advance line more frequently than necessary, which means you will go through string faster than with a manual bump feed. The 13-inch cutting swath is narrower than premium models, so trimming takes slightly longer for large yards.

How long can you expect the LST136 to last?

Based on user reports and the massive review base, this trimmer has an exceptional track record for longevity. Many reviewers mention owning theirs for five years or more with original batteries still holding charge. The 3-year warranty provides additional peace of mind.

The key to longevity appears to be proper battery care. Users who store the battery indoors and avoid complete discharges report the best long-term results. Replacing the battery after several years is normal, but the tool itself is built to last.

Is the 13-inch swath sufficient for larger yards?

For yards up to a quarter acre, the 13-inch swath is perfectly adequate. Each pass covers less ground than a 15 or 16-inch trimmer, but the lighter weight and excellent balance make the trade-off worthwhile for most users. For half-acre or larger properties, consider a wider swath model like the EGO ST1511T or Greenworks 60V.

The 8500 RPM motor speed compensates somewhat for the narrower swath by cutting quickly and cleanly through grass. The trimmer feels efficient despite its compact size.

9. WORX WG163 12″ Cordless String Trimmer – Best Budget Cordless Pick

The WORX WG163 is the number one best-selling string trimmer on Amazon with nearly 28,000 reviews, and it earns that position through a combination of low weight, low price, and surprising versatility. At just 5.52 pounds, this is the lightest trimmer I tested by a wide margin.

I handed this trimmer to my neighbor who has arthritis and struggles with heavier tools. She was able to use it comfortably for 20 minutes without wrist or shoulder fatigue. The 90-degree head tilt lets you trim along slopes and under fences without contorting your body, which is genuinely innovative.

The Command Feed system uses a push-button on the handle to advance line, which is more controlled than bump feed. WORX includes two batteries, so you always have a backup charging while using the other. The free spools for life program means you never pay for replacement line, which is an incredible long-term value.

The trade-offs are real, though. The 0.4Ah batteries deliver only 10 to 15 minutes of runtime each, and the charger takes over five hours per battery. This trimmer struggles with thick weeds and is best suited for light to moderate grass trimming on small to medium suburban lawns.

Is the free spools for life program actually worth it?

The free spools for life program is one of the best perks of owning a WORX trimmer. You pay shipping and handling (typically a few dollars) and WORX sends you replacement spools whenever you need them. Over the life of the trimmer, this can save $50 to $100 in line costs.

The process requires registering your trimmer and submitting requests through the WORX website. Some users report delays in receiving spools, but the program is legitimate and most customers receive their replacements within a few weeks.

Can this trimmer handle a medium-sized yard?

For a medium yard up to about 5,000 square feet, the WG163 can work if you manage the batteries strategically. Use one battery for the front yard, swap to the second for the back, and recharge both overnight. The narrow 12-inch swath means more passes, so budget extra time.

For anything larger or if you have significant weed problems, I recommend stepping up to a more powerful trimmer like the Ryobi 40V or EGO 56V. The WG163 excels as a lightweight trimmer for routine maintenance on smaller properties.

10. BLACK+DECKER 20V MAX 12″ String Trimmer (LST300) – Best for Small Yards

The BLACK+DECKER LST300 is purpose-built for small yards and light trimming duty. At 5.7 pounds with a 2.0Ah battery, it is one of the most comfortable trimmers to use for anyone who finds heavier tools tiring. The 6200 RPM PowerDrive transmission provides enough cutting speed for regular grass maintenance.

I tested this primarily on a small front yard with typical suburban grass along sidewalks and flower beds. It handled the job well, producing clean cuts without tearing the grass. The automatic feed spool worked reliably throughout testing, advancing line at consistent intervals.

The trimmer-to-edger conversion takes about five seconds. You rotate the head and reposition the handle, then use the built-in wheel guide to edge along hard surfaces. For small properties where storage space is limited, having one tool handle both tasks is practical and economical.

Battery runtime is the main limitation at 15 to 20 minutes per charge. The included 2.0Ah battery is adequate for a small yard but will not complete a larger job on one charge. The charger also takes over five hours, so planning ahead is essential.

How does the LST300 compare to the WORX WG163?

Both trimmers target the same small-yard, budget-conscious buyer. The WORX WG163 is lighter at 5.52 pounds versus 5.7 pounds and includes two batteries instead of one. The WORX also offers the free spools for life program, which adds long-term value.

The BLACK+DECKER LST300 has a larger 2.0Ah battery versus the WORX’s 0.4Ah packs, meaning each charge lasts longer despite the similar overall runtime. The LST300 is also generally quieter in operation. Choose the WORX for the dual-battery convenience and free spools, or the LST300 for the larger battery capacity and quiet operation.

What yard size is ideal for this trimmer?

The LST300 is ideal for yards up to approximately 3,000 square feet of grass area. This covers most townhouse lawns, small front yards, and courtyard spaces. The 12-inch swath is efficient for tight spaces where a wider trimmer would be unwieldy.

For yards larger than 3,000 square feet, the battery runtime becomes a limiting factor. Consider the BLACK+DECKER 40V LST136 for medium yards or step up to an EGO or Ryobi 40V system for larger properties.

11. BLACK+DECKER BESTA510 14″ Corded String Trimmer – Best Corded Value

The BLACK+DECKER BESTA510 is the best corded electric string trimmer I tested for homeowners who want unlimited runtime without battery limitations. At just $55.86 with over 17,000 reviews, it represents outstanding value for small to medium yards with accessible outdoor outlets.

The 6.5-amp motor delivers consistent power that never fades, which is the fundamental advantage of corded trimmers. You never need to stop and wait for a battery to charge. I trimmed my entire front and back yard in one session without any power interruption, something no budget cordless model can match.

The 2-in-1 design converts to an edger for sidewalk and driveway work. The 14-inch cutting swath is wider than budget cordless models, covering more ground per pass. At 6.3 pounds, the weight is very manageable even for extended use.

The main trade-off is the cord. You need a heavy-duty outdoor extension cord (12-gauge recommended) and an outdoor outlet within 100 feet of your work area. The cord retention system helps prevent accidental disconnections but is not perfect. Maneuvering around trees and garden beds requires cord management awareness.

What extension cord do you need for this trimmer?

BLACK+DECKER recommends a 12-gauge outdoor extension cord for runs up to 100 feet. For shorter runs under 50 feet, a 14-gauge cord is acceptable. Using a cord that is too thin will cause voltage drop, reducing motor power and potentially damaging the trimmer over time.

Invest in a high-quality outdoor-rated cord with a locking socket to prevent the trimmer plug from disconnecting during use. A cord reel or hanger makes storage and deployment much easier.

When does a corded trimmer make more sense than cordless?

A corded trimmer is ideal when you have an outdoor outlet within 100 feet of your entire work area and your yard is small to medium sized. The advantages are unlimited runtime, lower purchase price, no battery degradation over time, and lighter weight since there is no battery pack.

A cordless trimmer is better for larger properties, areas without convenient outlet access, or users who find cord management frustrating. Many homeowners own both types: a corded model for quick front yard touch-ups and a cordless for larger jobs.

12. CRAFTSMAN WEEDWACKER 14″ Corded Electric (CMEST913) – Best Corded Lightweight

The CRAFTSMAN CMEST913 is the lightest corded trimmer in this roundup at just 5.7 pounds. That weight advantage makes it incredibly easy to maneuver, especially for users who find heavier trimmers fatiguing. The 6.5-amp motor provides steady power comparable to the BLACK+DECKER BESTA510.

The push-button line feed is a nice alternative to bump feed. Instead of tapping the head on the ground, you press a button on the handle to advance line. This is gentler on the trimmer head and more precise, though some users report the mechanism becoming unreliable after several months of heavy use.

I appreciated the VERSATRACK compatibility, which lets you hang the trimmer on CRAFTSMAN’s wall organization system. The adjustable pole length accommodates different heights, and the overall build quality feels solid for the price point.

The cutting performance matches what you would expect from a 6.5-amp corded trimmer. It handles regular grass and light weeds well but can struggle with very thick or woody material. The 14-inch swath provides good coverage for most residential yards.

How does the CMEST913 compare to the BLACK+DECKER BESTA510?

Both trimmers offer 6.5-amp motors and 14-inch cutting swaths, so core performance is similar. The CRAFTSMAN is lighter at 5.7 pounds versus 6.3 pounds, making it slightly easier to handle. The CRAFTSMAN uses push-button feed while the BLACK+DECKER uses auto feed.

The BESTA510 has a significantly larger review base (17,295 versus 1,325), which suggests stronger long-term reliability data. The BESTA510 is also less expensive. Choose CRAFTSMAN for the lighter weight and push-button convenience, or BLACK+DECKER for proven reliability at a lower price.

What maintenance does a corded electric trimmer need?

Corded trimmers require minimal maintenance compared to gas models. After each use, clean grass and debris from the cutting head and air intake. The CMEST913 has an air intake that can clog, so checking this regularly prevents overheating.

Replace the trimmer line when it runs low, and inspect the extension cord for damage before each use. Store the trimmer in a dry location to prevent electrical component corrosion. With basic care, a corded trimmer can last five to ten years.

How to Choose the Best Electric String Trimmer: Buying Guide

Choosing the right electric string trimmer comes down to understanding your yard size, power preferences, and budget. This buying guide walks through every key decision factor based on what our team learned from testing 12 models across different yard conditions.

Corded vs Cordless Electric String Trimmers

Corded trimmers plug into a standard outdoor outlet and provide unlimited runtime. They are lighter, less expensive, and never need battery replacements. The limitation is range: you need an outdoor outlet within 100 feet of your work area, and managing the extension cord adds a layer of complexity.

Cordless trimmers run on rechargeable batteries and offer complete freedom of movement. They are more expensive upfront and batteries eventually need replacement, but the convenience of no cords is significant. Modern 40V to 60V batteries deliver 30 to 90 minutes of runtime, which covers most residential yards on a single charge.

Choose corded if you have a small yard with convenient outlet access and want the lowest cost and lightest weight. Choose cordless if you have a larger property, value freedom of movement, or plan to invest in a battery ecosystem with multiple tools.

Cutting Swath Width

Cutting swath is the width of grass the trimmer cuts in a single pass. Wider swaths cover more ground quickly but can be harder to maneuver in tight spaces. Most electric trimmers range from 12 to 17 inches.

For small yards with lots of obstacles (trees, flower beds, fences), a 12 to 13-inch swath provides better precision. For medium to large open areas, 15 to 17 inches is more efficient. The DeWalt DCST972X1 offers an adjustable swath that lets you switch between widths depending on the task.

Battery Voltage and Runtime

Battery voltage directly correlates with cutting power. Here is how the common voltages compare: 20V systems are entry-level and best for light trimming, 40V systems are mid-range and handle most residential needs, 56V to 60V systems deliver near-gas-equivalent power, and 80V-plus systems are professional-grade.

Runtime depends on both voltage and amp-hour (Ah) capacity. A 4.0Ah battery roughly doubles the runtime of a 2.0Ah pack at the same voltage. Consider buying a spare battery if your yard requires more than 30 minutes of continuous trimming.

Weight and Ergonomics

Weight is one of the most important factors for user comfort. The trimmers in this guide range from 5.5 pounds (WORX WG163) to 15 pounds (DeWalt DCST972X1). Lighter trimmers reduce fatigue and are essential for users with physical limitations.

Beyond raw weight, balance matters enormously. A well-balanced trimmer feels lighter than its actual weight because the load is distributed between your hands rather than concentrated at the cutting head. Telescoping shafts help match the trimmer length to your height, reducing back strain.

Line Feed Systems

The line feed system determines how fresh cutting line is advanced as it wears down. Bump feed requires tapping the head on the ground to release more line. Automatic feed senses when line is needed and advances it without user input. Push-button feed lets you control advancement from the handle.

EGO’s PowerLOAD system goes a step further by automatically winding new line onto the spool when you need to reload. This eliminates the most frustrating maintenance task in string trimmer ownership. Forum users consistently cite string loading as their top pain point with trimmers.

Battery Ecosystem and Brand Compatibility

When you buy a cordless trimmer, you are investing in a battery platform. Most brands design their batteries to work across dozens of tools. This means buying a trimmer from Ryobi, EGO, or Milwaukee opens the door to mowers, blowers, chainsaws, and hedge trimmers using the same batteries.

Consider which brand offers the tools you are likely to need in the future. EGO and Greenworks focus exclusively on outdoor power equipment. Milwaukee and DeWalt bridge power tools and outdoor equipment. Ryobi offers the widest range at the most affordable prices. Buying multiple tools from the same brand can save approximately 30 percent by eliminating redundant battery purchases.
