Our top picks

1. Ryobi RY40290 – Best cordless electric

Our overall favorite electric string trimmer is the 15-inch Ryobi RY40290. With superb power and extended runtime, it’s the best battery-powered model. Its carbon fiber shaft is highly durable, lightweight, and attachment-capable. You can turn the trimmer into additional yard care tools, including a brush cutter and cultivator.

Cutting Power: Its high-performance brushless motor makes it as potent as many gas trimmers. When the dual-speed trigger’s on high, the pre-cut 0.095-inch dual-string effortlessly gashes through dense weeds and overgrown grass. The Reel Easy 3-in-1 head provides versatility with three cutting options — bump feed, fixed-line, or serrated blades.

Ease of use: The RY40290 is easy to assemble, operate, and maneuver. It’s well-balanced with an adjustable handle and comfortable grips. The line feed system takes some getting used to, but loading a new line gets quick and easy with time.

Battery life: The included 40-volt, 4 Ah battery provides up to 72 minutes of runtime. Heavy-duty trimming rapidly reduces battery life, but the trimmer typically runs at least 45 minutes on a single charge. It comes with a fast charger that fully refuels the battery within an hour.

Specifications

• Battery: 40-volt, 4 Ah
• Cutting swath: 15 in.
• Line gauge: 0.095 in.
• Line feed: Bump / fixed
• Motor: Brushless
• Shaft length: 50.5 in.
• Shaft type: Straight
• Warranty: 5-year tool / 3-year battery
• Weight: 11.5 lb.

2. Ego Power+ ST1523S – Cordless runner up

The second best battery string trimmer is the 15-inch Ego Power+ ST1523S. It features innovative technology, efficient power, and a user-friendly design. Additionally, it’s highly durable, with weather-resistant construction and a lifetime warranty on its carbon fiber shaft.

Cutting Power: The professional-grade, 0.095-inch dual-line potently penetrates pervasive weeds and severely overgrown grass. A high-efficiency brushless motor empowers Ego’s patented PowerLoad head. It has variable speed control. But even at the slowest speed, it trims delicate areas like a bull in a china shop.

Ease of use: It’s user-friendly and easy to set up. Loading new string is child’s play with Ego’s push-button auto-feed. However, it’s heavy. Being a petite woman, I strained with its weight. Since the weight’s well-balanced, I think most average-sized men can handle it.

Battery life: Its 56-volt, 4 Ah ARC Lithium battery provides up to 50 minutes of runtime, and most homeowners get at 30 to 45 minutes of battery life. The battery recharges in about 80 minutes with the included standard charger. Ego’s ARC lithium batteries are top-ranked for performance and durability.

Specifications

• Battery: 56-volt, 4 Ah
• Cutting swath: 15 in.
• Line feed: Bump / Auto
• Line gauge: 0.095 in.
• Motor: Brushless
• Shaft length: 42 in.
• Shaft type: Straight
• Warranty: 5-year tool / 3-year battery
• Weight: 18.5 lb.

3. Greenworks 21142 – Best corded electric

The best corded electric string trimmer is the 18-inch Greenworks 21142. It’s ergonomic, robust, and less than ⅓ the cost of the previous trimmers. Additionally, it turns into other lawn care tools using many branded attachments, including Ryobi and TrimmerPlus.

Cutting Power: A mighty 10 Amp motor ignites its pro-style metal-gear head. With its broad swath and 0.080-inch dual trimmer line, it quickly cuts most tall grass and yard weeds. But with just one speed, it’s too powerful to properly care for delicate areas.

Ease of use: The trimmer is well-balanced, easy to assemble, and straightforward to use. Its cushioned over-mold grip and auxiliary handle enhance comfort and control. The long shaft makes weeds easy to reach, but the trimmer is cumbersome for small users to maneuver.

Extension cord: Its cord lock feature keeps the plug secure. The owner’s manual recommends extension cord specs shown in the table below.

Specifications

• Cutting swath: 18 in.
• Line feed: Bump
• Line gauge: 0.080
• Motor: 10 Amp brushed
• Shaft length: 54 in.
• Shaft type: Straight
• Warranty: 3-year tool
• Weight: 9.9 lb.

4. WORX WG154 – Best for flower beds

The WORX WG154 is the best electric string trimmer for flower beds. It’s affordable and practical. The 2-in-1 tool has two modes — trimming and edging. Additionally, it has an adjustable flower guard that prevents accidental damage to flowers, ornamentals, and lawn decor. It’s the ideal tool for light-duty trimming throughout yards and gardens.

Cutting Power: The 0.065-inch single-line is excellent for light-duty trimming but can’t handle heavy-duty weeds.

Ease of use: It’s easy to set up, operate, and maneuver. The 4-pound trimmer is light enough for me to manage single-handedly. With its push-button auto-feed, loading new line is lightning fast. Switching the cutting mode (i.e., trimmer/edger) is quick and painless; just pull and twist the rotating head.

Battery life: The included 20-volt, 2 Ah battery typically provides 15 to 30 minutes of runtime and recharges in about 5 hours.

Specifications

• Battery: 20-volt, 2 Ah
• Cutting swath: 10 in.
• Line feed: Automatic
• Line gauge: 0.065 in.
• Motor: Brushed
• Shaft length: 41 in.

5. Echo DSRM-2600R2 – Best for pros

If you crave cutting power, you’ll covet our favorite electric pro trimmer — the 17-inch Echo eForce X Series Trimmer. It’s potent, reliable, and quiet. Echo’s cutting-edge tech lets you weed eat like a pro without gas fumes or earth shaking noise.

Cutting Power: A reliable brushless motor gives the trimmer head about as much force as a 25-cc gas engine. Its 0.095-inch Silentwist trimmer line quickly cuts through dense overgrowth. It has three cutting speeds and a broad 17-inch swath.

Ease of use: It’s easy to use. The long, 59-inch shaft can reach just about any weed. With ergonomic grips, low vibration, and a rare-mounted motor, it’s well-balanced and easy to control. Its Speed Feed 400 trimmer head doesn’t require disassembly to load a new spool.

Battery life: The 56-volt, 5 Ah battery provides up to 54 minutes of runtime and recharges in 2.5 hours with the included standard charger. Echo’s MAXOUT technology ensures the trimmer maintains full power, even when the battery’s low.

• Line gauge: 0.095 in.

6. Ego Power+ ST1511T – Best telescopic shaft

The 15-inch Ego Power+ ST1511T is the best telescopic string trimmer. With IPX4 weather-resistant and an adjustable aluminum shaft, it’s built for performance, durability, and comfort.

Cutting Power: The pro-grade 0.095-inch spiral-twist string crisply cuts thick weeds and tall grass. It has two cutting speeds and only bogs down when weeds are both tall and thick.

Ease of use: It’s easy to assemble, operate, and maneuver. The weight is well-balanced and easy to handle for prolonged periods. The shaft is easy to adjust, which improves comfort and reach. Additionally, it features the same user-friendly auto-feed as the Ego Power+ ST1523S.

Battery life: The 56-volt, 2.5 Ah Arc Lithium battery provides up to 45 minutes of runtime and recharges in under an hour with the included Power+ charger. Heavy-duty trimming can cause the battery to drain in as little as 20 minutes, but most homeowners get at least 30 minutes of runtime per charge.

• Cutting swath: 15 in.
• Line gauge: 0.095 in.

7. Black+Decker GH3000 – Best curved shaft

The best electric curved-shaft string trimmer is the 14-inch Black+Decker GH3000. It’s light as a breeze with unlimited runtime and a paltry price. Featuring Black+Decker’s Groom N’ Edge trimmer head, the corded tool quickly converts between a string trimmer and an edger. Additionally, its wheeled edge guide makes accuracy effortless.

Cutting Power: With a 7.5 Amp motor, the Groom N’ Edge head spins as fast as 7,500 RPM. The 0.080-inch line cuts through thick weeds and tall grass quicker than most electric curved shaft trimmers. However, it bogs down on excessively thick weeds and highly dense overgrowth.

Ease of use: Setup is simple, and trimming is as easy as pie. The tool is very lightweight and easy to maneuver. Quickly flip a latch to switch between edging and trimming. Crisp, clean edges are pain-free with the edge guide, even around curved walkways and landscaping. The auto-feed system needs no bumping, but its intuition is sometimes off, resulting in wasted string.

Extension cord: The owner’s manual recommends extension cord specs shown in the table below.

Specifications

• Cutting swath: 14 in.
• Line diameter: 0.080 in.
• Line feed: Auto
• Motor: Brushed, 7.5 Amp
• Shaft length: 45 in.
• Shaft type: Curved
• Warranty: 2 years
• Weight: 6.9 lb.

Buyer’s guide

To buy the best string trimmer, you must compare critical specs. If you’re shopping for an electric model, consider the following:

• How string trimmers work
• Corded Vs. Cordless
• Electric Motors
• Cutting swath
• Shaft style
• Weight
• Price

How string trimmers work

String trimmers are the best tools for cutting grass, weeds, and ground cover in places a lawn mower can’t. They have long shafts that reach beneath decks and patios. They also edge along lawns, landscaping, and fence lines.

A spool of string called a trimmer line feeds through the head. The string speedily spins, slicing through overgrowth. Trimmer line comes in various widths, and the best weed eater string depends on the thickness of your weeds and the specs of your trimmer. Some use string as thick as 0.105 inches or as thin as 0.065 inches.

Corded Vs. Cordless

Electric string trimmers come in corded and cordless models.

• Cordless electric string trimmers cost more than corded models but are more convenient and better for larger yards. Powered by lithium-ion batteries, cordless models have limited runtime and lengthy charge times. Choose the best battery-powered trimmer by ensuring it can cut your entire yard on a single charge.

• Corded electric string trimmers cost significantly less than cordless models. They have unlimited runtime and don’t need charging. However, an extension cord keeps homeowners on a leash. Most models have a max extension cord length of 100 or 150 feet.

The table below shows the typical battery life and charge time of cordless electric trimmers.

Electric Motors

The type of motor in an electric string trimmer is crucial to its performance and durability. The motor converts electrical energy into mechanical energy, causing the trimmer’s head to spin. Corded electric string trimmers typically have brushed motors, while battery-powered models may have a brushed or brushless motor.

Brushed vs. brushless motors:

• Weight: Brushless motors are lighter, improving comfort and prolonging battery-powered runtime.

• Durability: Brushless motors tend to have a longer lifespan.

• Maintenance: Brushless motors have less moving parts, thus require less maintenance and fewer repairs.

• Cost: Brushed motors are more affordable.

• Vibration: Brushless motors vibrate less, so they’re typically quieter and more ergonomic.

Cutting swath

Electric weed eaters have a 10- to 20-inch cutting swath (i.e., cutting width). This tells you how large an area they trim in a single pass. Homeowners with large yards prefer a wider swath, but smaller trimmers are lighter and easier to maneuver.

Corded string trimmers tend to have a slightly broader swath than cordless models, as shown in the table below.

Shaft style

There are three main trimmer shaft styles:

• Straight-shaft string trimmers are the most common and most durable. Additionally, they have the best cutting power.

• Curved-shaft string trimmers are handy for maneuvering around landscaping. Although lighter and more affordable than straight-shaft models, they have a shorter reach and lifespan.

• Telescopic shaft string trimmers have an adjustable reach. You can adjust the trimmer’s height to suit the job or your stature.

Weight

A typical electric string trimmer weighs 6 to 15 pounds. Lighter trimmers are more comfortable and easier to maneuver, but models with a wider cutting swath typically weigh more.

The table below shows that corded string trimmers tend to weigh slightly more than cordless trimmers.

Price

Most electric string trimmers cost $80 to $300, with the average model costing about $170.

Corded Vs. Cordless Cost: Cordless electric string trimmers cost significantly more than corded models, as shown in the table below.

Cost of batteries: If you decide to purchase one of the best cordless string trimmers, don’t forget to factor in the cost of lithium-ion batteries. All the models on our list come with a battery and charger, but that’s not always the case. Additionally, most string trimmer batteries have a 2 to 3 year warranty and need replacing within 5 years.

Cost of extension cords: If you choose a corded model, expect to pay $20 to $225 for a new string trimmer extension cord. Most models don’t come with one. Longer cords with thicker gauges cost more. However, I like to hunt for extension cords at thrift shops to save a pretty penny.
