Best Electric String Trimmer: Corded and Battery Models Compared

As an Amazon Associate we earn from qualifying purchases. Details

If you are looking for the best electric string trimmer, the answer turns on one question: is there an outdoor outlet within reach of your lawn? A corded model has no battery to charge, but its cord limits how far you can work. A battery model frees you from the cord, but a tool-only listing needs a pack and charger you may not own. This guide compares eight electric string trimmers using only their listing data, explains the trade-offs, and sets out the safety checks that apply to cords, batteries and flying debris.

Quick answer

• Choose a corded model if an outdoor outlet is close and you would rather not charge batteries. The Virginia Tech guide notes that the power cord limits the area a corded trimmer can cover.
• Choose a battery model if your yard is far from any outlet. Three cordless picks here list two 2.0Ah packs and a charger in the box, and two of them give about 30 minutes of run time.
• Check the battery platform before buying a tool-only listing. The Worx WG163.9, Worx WG186.9 and Elegarden listings all say the battery and charger are not included or sold separately.
• Read the safety section before you start. Thrown debris, damaged cords, wet grass and lithium-ion battery handling are the hazards the pages we opened cover.

What an electric string trimmer is

A string trimmer, also called a line trimmer or weed eater, cuts grass and weeds with a flexible line spinning on a head at the end of a shaft. An electric version replaces the gasoline engine with a motor that runs from a cord or a battery. The Virginia Tech guide describes electric trimmers as relatively light and easy to handle, but generally less powerful and less robust than gasoline models. It also says newer electric models can match gasoline trimmers in performance, so an electric model can suit a small or medium yard well.

In this comparison, the corded group draws power from an outdoor outlet through an extension cord. The battery group uses lithium-ion packs. The listings name 20V, 21V and 40V systems, plus one tool-only listing that is compatible with selected 18V packs. The keyword does not specify a power source, so this guide covers both groups and marks which picks need a pack you may not own.

Corded or battery: what each one gives up

Corded models

Corded trimmers have no pack to charge, and their power stays steady for as long as the cord reaches. The trade-off is reach. The Virginia Tech guide says the power cord limits the area that can be covered. It also ties the low power output of electric trimmers, roughly 400 to 1,200 watts, to a line size limit of 2.5 mm (0.10 inch).

Two corded listings in this set show that line size at work. The CRAFTSMAN CMEST900 lists a 0.065 inch line, and the Hoteche lists a 2.0 mm string head. The conversion is 2.0 divided by 25.4, which is about 0.08 inch, so the Hoteche line sits under the 0.10 inch limit the guide gives.

Corded trimmers also depend on the extension cord. The UT Austin extension cord factsheet says a cord must handle the amperage rating of the equipment it powers, that an indoor cord should not be used outdoors, and that cords must be the three-wire grounded type. The CRAFTSMAN listing’s style name reads “Cord Not Included,” so budget for an outdoor-rated cord from the start. The Hoteche listing does not state its cord length, so measure the distance from your outlet to the far corner of the lawn before you buy.

Battery models

Battery models trade the cord for a pack, and the pack is where most buying decisions sit. Two listings in this set give about 30 minutes of run time from two 2.0Ah packs, and both phrase it as up to or around that figure, not as a guarantee. The KOMASTY listing advises letting the batteries cool for a few minutes after use before recharging, and says this helps the battery lifespan.

The Worx WG186.9 listing says its batteries are sold separately and recommends Power Share Pro packs WA3012 (4.0Ah) and WA3571 (5.0Ah). That detail matters because a tool-only purchase can mean a second purchase before the trimmer works. The Elegarden listing names selected 18V models from BL1820 to BL1860 and tells you to verify your battery model before buying.

Battery models also bring handling rules. The EPA says to tape the battery terminals, or to place each lithium-ion battery in a separate plastic bag, to prevent fires. It says used lithium-ion batteries belong at separate recycling or household hazardous waste collection points, not in household garbage, and that a damaged battery needs the manufacturer’s handling guidance.

Who should buy which type

Buy a corded model if an outlet can reach the whole lawn, you want no charging, and you can keep the cord clear of the trimmer head. The CRAFTSMAN CMEST900 suits a smaller lawn with an outlet nearby. The Hoteche suits taller grass and thicker weeds when the outlet is close enough.

Buy a battery model with packs and a charger included if your lawn is more than a cord’s length from an outlet. The KOMASTY, SUNCHERS and RAXONE listings all say two packs and a charger are in the box. Buy a tool-only model only if you already own a compatible pack, or if you are ready to buy one. The Worx WG163.9, the Worx WG186.9 and the Elegarden fall into this group.

If you plan to edge along walkways as well as trim, the listings for the Worx WG163.9 and the SUNCHERS describe an edger mode or auxiliary wheel. The Hoteche listing names trimming as its only recommended use, so it is not the pick for a dedicated edging job. For a related guide, see how to edge a lawn with a string trimmer.

How we chose

We started from the twelve listings that the research file matched to this keyword. For each one we read the title, the bullets and the specification lines, and nothing else. We did not use prices, customer ratings or sales rank, because none of those show how a trimmer behaves in a yard.

Two filters came first. We kept only listings for an electric string trimmer, corded or battery. We dropped two listings whose titles present them as 4-in-1 brush cutters with multiple blade types, which is a different job from string trimming. Of the remaining ten, we chose eight.

We left out the JAGROM listing because its 20V, two-pack and 9,500 rpm setup duplicates the KOMASTY and SUNCHERS listings, and its listed weight of 7 pounds is the highest among the 20V cordless listings. We left out the Yudara listing because its bullets describe a brush-cutting set with a circular saw blade for branches, and its 23,000 rpm figure is far above the other listings.

Each pick then had to pass four checks:

• Power source, and whether the battery and charger are included.
• Listed speed and listed cutting width.
• Listed weight.
• One feature that changes daily use, such as auto line feed, an edger conversion, a dual-interlock switch or a spool count.

Where a listing leaves a field blank, we write “not listed” rather than estimate it. We do not rank the picks, because listing data cannot show which one cuts better or lasts longer.

Side-by-side listing data

Pick	Power	Listed speed	Listed cutting width	Battery and charger	Listed weight
CRAFTSMAN CMEST900	Corded electric	Not listed	12 inches	Cord not included (style name)	Not listed
Hoteche G840211A	AC (mains) power	10,500 rpm	13 inches	Not listed	Not listed
KOMASTY TT-BBC2012BM-1Z	20V battery	9,500 rpm	12 inches	Two 2.0Ah packs and charger included	Not listed
SUNCHERS	20V battery	9,500 rpm	12 inches	Two 2.0Ah packs and charger included	Not listed
RAXONE HG0556	21V battery	9,500 rpm	12 inches	Two 2.0Ah packs and fast charger included	5.95 lbs
Worx WG163.9	20V battery	7,600 rpm	12 inches	Not included	4.6 pounds
Worx WG186.9	40V battery	Not listed	15 inches	Sold separately	8.8 pounds
Elegarden EL-BBC2030A	Battery (selected 18V models)	8,500 rpm	12 inches	Not included	3.8 lbs

Three short calculations come straight from the table.

Weight spread. The heaviest pick is the Worx WG186.9 at 8.8 pounds, and the lightest is the Elegarden at 3.8 pounds. The gap is 8.8 – 3.8 = 5.0 pounds, which is more than the full 4.6-pound weight the Worx WG163.9 listing gives for its tool.

Cutting width. The 15-inch head on the Worx WG186.9 is 15 – 12 = 3 inches wider than the 12-inch heads in the table.

Run time. Taking the listed figure of up to 30 minutes at face value, a one-hour job (60 minutes) needs at least two full pack cycles. The listing figure is a ceiling, so plan for a second charge on bigger jobs.

Safety rules that apply to these trimmers

Thrown debris and bystanders

Weed trimmers can throw stones, sticks and other objects at high speed. The Texas A&M AgriLife lawn maintenance safety guide says so, and the Virginia Tech guide says the same for string trimmers. Walk the area first and remove glass, limbs, rocks and trash that could become a projectile. Keep children and bystanders out of the way before you start.

The Virginia Tech guide also warns that automatic-feed and bump-feed heads may release more line than you expect, which raises the chance of the string striking the operator. Check the string length often, and keep the head below waist level.

Eye, ear and body protection

The Virginia Tech guide advises eye and ear protection whenever you operate power tools. The Texas A&M guide lists goggles or safety glasses and ear plugs for trimmer work, along with long pants, long sleeves, gloves and hard boots. The University of Florida IFAS mower safety guide also says eye and ear protection are always a good idea.

Cord checks for electric trimmers

Inspect the power cord for cuts, nicks and scrapes, and replace a damaged cord right away. The Virginia Tech and Texas A&M guides both give this instruction for electric trimmers. The UT Austin factsheet adds that if a cord’s conductors become exposed there is a danger of shock, burns or fire, and that electrical tape is not a solution for a damaged cord.

Watch for exposed electrical wires, communication lines and extension cords in the work area, since the string can damage them. Both the Virginia Tech and Texas A&M guides name this hazard.

Wet grass, unplugging and stance

Do not run an electric trimmer when conditions are wet or near puddles. The Virginia Tech and Texas A&M guides both say so. Unplug the trimmer before you inspect it, clean it, adjust it or replace the string. Texas A&M also advises never leaving an electric trimmer plugged in while it is unattended.

Maintain balance and firm footing, and avoid over-reaching, according to the Virginia Tech guide.

Outlets and household wiring

The pages we opened cover the trimmer, its cord and its battery. They do not cover household wiring. If you suspect a problem with an outlet or the wiring behind it, have a licensed electrician handle the work. Do not open outlet boxes or work on live wiring yourself.

Lithium-ion packs

Handle lithium-ion packs as the EPA describes: tape the terminals or bag each battery separately to prevent fires, take used packs to a separate recycling or household hazardous waste point, and contact the manufacturer for handling information if a pack is damaged.

Picks at a glance

Each card gives a reason drawn from that listing, a skip-if case and at least one limitation.

What we could not verify

• The run times, speeds, cutting widths and weights in this article come from the listings. The pages we opened do not give measured run times or cutting results for any of these models.
• Claims such as the 1000W motor power in the Hoteche listing, the gas-like performance in the KOMASTY listing and the brushless motor in the Worx WG186.9 listing come from those listings. We have no independent page that confirms them for these models.
• Battery compatibility for the Elegarden, which names selected 18V models, rests on the listing text alone.
• Warranty and after-sales service wording in several listings is not covered by the pages we opened.
• The pages we opened do not compare these models with each other, so this guide does not say that one brand lasts longer than another.
• Noise, vibration and real-world weight during use are not covered by the pages we opened. The weights given are the listed figures.
• Where a field reads “not listed,” we have not estimated it.

FAQ

Is a corded or battery electric string trimmer better?

Neither is better for every yard. A corded trimmer suits a lawn that an outlet and cord can reach, and it avoids managing packs. A battery trimmer suits a yard far from outlets, but you need to plan for packs, chargers and the run time each pack allows. The pages we opened do not rank the two types by overall performance, so the choice comes down to your reach and how you feel about charging and cord management.

Do the cordless picks include a battery and charger?

Three of them do. The KOMASTY, SUNCHERS and RAXONE listings all say two packs and a charger are included. The Worx WG163.9 listing says the battery and charger are not included. The Worx WG186.9 listing says they are sold separately and names Power Share Pro packs. The Elegarden listing says they are not included and names selected 18V models from BL1820 to BL1860, and it asks you to verify your model before buying.

How long does a pair of 2.0Ah batteries run?

The KOMASTY listing says two 2.0Ah batteries provide up to 30 minutes of continuous power, and the SUNCHERS listing says around 30 minutes. Neither listing gives a measured figure for a specific task, so treat the number as an upper guide. For larger jobs, plan a second charge, and let the packs cool for a few minutes before recharging, as the KOMASTY listing advises.

Can an electric string trimmer clear thick brush?

The Virginia Tech guide says electric trimmers are generally less powerful than gasoline models, so heavy brush is outside what most electric listings promise. The KOMASTY listing says to avoid cutting excessively thick or dense grass to prevent line breakage. The Hoteche listing does include a 230 mm three-tooth blade for thicker weeds and brush, but the pages we opened do not confirm how that blade performs.

Do I need eye and ear protection with an electric trimmer?

Yes. The Virginia Tech guide advises eye and ear protection when operating power tools, and the Texas A&M guide lists goggles or safety glasses and ear plugs for trimmer work.

Bottom line

If an outdoor outlet cannot reach the whole lawn, choose a battery model whose listing includes its packs and charger. If an outlet is close and you want no charging, choose a corded model with an outdoor-rated extension cord that handles the tool’s amperage. Choose a tool-only listing only when you already own a compatible pack.
