Whether you’re slashing your way through waist-high grass, trimming the edges on your lawn, or cutting away weeds in the driveway bricks, a weed eater is a versatile and indispensable machine that belongs in every gardener’s tool shed.

Most of us think of a lawnmower as the backbone of our garden care tools. However, a weed eater is a more versatile machine. A weed eater might not give you the stunning level finish on your grass that a lawnmower provides, but you can still use it to cut back grass where a lawnmower can’t reach.

A weed eater is an essential gardening machine that you can’t do without in the yard. However, if you head online to your favorite retailer, you might find the amount of selection somewhat intimidating.

Reading through spec sheets and analyzing the performance of a prospective weed eater you’re thinking about purchasing takes time. We decided to take the effort out of choosing the best weed eater for your yard.

Our reviews of the best weed eaters allow you to make an informed purchase decision on the weed eater that’s right for your garden. In the review section, we look at the top models on offer and follow it up with a buyer’s guide to help you narrow down your choices.

This battery-powered weed eater also comes with an automatic feed spool, taking the hassle out of your trimming.

Depending on the power level you use while running the machine, you can expect anywhere from 20 to 40-minutes of run time. It takes the charging unit around an hour to fully charge the battery pack to capacity.

Those homeowners with a passion for DIY will recognize the Makita brand. Makita design and construct some of the best DIY power tools available. The battery-powered weed eater from Makita is no exception to this rule.

The Makita features top-quality design and premium components in its construction.The Makita XRU09PT1 Cordless String Trimmer gets the award for the best premium model in this review, and when we take a look at the specs, combined with the brand reputation, it’s easy to see why this machine costs a small fortune.

Still, die-hard Makita fans won’t use anything else, and this machine offers you the best weed eater performance in this review.

With the machine weighing under 10-pounds, it feels light in your hands, with an excellent balance. Makita also offers an adjustable sling strap accessory for those gardeners trimming large properties.

The machine uses a bump head, line feeding system, and some users report they experience wear on the bump head. Fortunately, Makita offer replacement bump heads for this model as well.

Worx WG163 Battery Weed Eater – Best Value Model

If you’re working with a budget, and you’re looking for the best value option in this review, then you can’t go wrong with the Worx WG163 Weed Eater. This machine will suit the cost-conscious gardener and still manages to provide excellent performance.

The Worx provides you with a dual cutting operation for trimming and edging, and you also get a telescopic handle to adjust the machine to your user height.

The machine operates on the 20-volt Worx lithium-ion battery setup, and the battery is interchangeable with other Worx machines as well.

The only gripe we have with this machine is that it comes with small wire spools, and the trimming line breaks quickly. These factors mean that gardeners will replace the line and cutting heads often, driving up the cost of ownership in the long term.

However, you can’t beat the price of this battery-powered weed eater, and that’s why we chose it as the best value offering in this review.

  • The winner for the best budget machine in this review
  • Affordable
  • Dual trimming and edging functionality
  • Telescopic handle
  • Compatible with all Worx 20-Volt battery systems
  • Small cutting wire spools

DeWALT DCST920P1 Battery-Powered Weed Eater

If there’s another brand that’s synonymous with quality in DIY power tool manufacturing, its DeWALT. This company releases some top-quality machines, with a wide range of functionality. The weed eater is no different, and dedicated DeWALT fans will find this offering suits all of their weed-eating needs.

The DEWALT DCST920P1 battery powered weed eater has a powerful motor capable of ripping through the most robust grass.

The 20-volt battery pack provides enough energy to the machine to allow it to cut through any task you throw at it. The battery run time is excellent, and you can expect anywhere from 25 to 40-minutes of use on a single charge.

Some users report cutting sessions as long as an hour off of one charge when using the low power setting.

The only gripe we have with this battery-powered weed eater is the user reviews. There are quite a few reviews regarding the quality control on this model. Therefore, if you experience any issues, don’t hesitate to send it back to the manufacturer.

Because of the quality control issues with this battery-powered weed eater, we feel more comfortable recommending the Makita for the top premium buy in this review.

  • Premium, reputable DIY power tool brand
  • Compatible with all 20-Volt DeWALT battery pack systems
  • 13-inch clearance range
  • Low and high operating modes for better user control
  • Extended run time from a lithium-ion 20-volt battery pack
  • User reviews reveal some quality control issues

Greenworks 2101602 Battery-Powered Weed-Eater

The Greenworks 2101602 Battery-Powered Weed-Eater offers gardeners with an affordable and powerful weed eater to suit any garden. It was challenging for us to choose between the Worx and this model for the best value weed eater in this review.

However, while the Greenworks may have lost the title to the Worx, that’s not to say that this machine is not worth the buy. The Greenworks comes with a 40-volt battery pack, which is better than many of the models in this review.

The battery packs are also interchangeable with other 40-volt Greenworks batteries, allowing you to keep the charge going while you’re cutting your lawn. While the 40-volt battery is impressive, it didn’t provide the machine with the run time we expected.

With the high power setting, some users report run times as low as 20-minutes, which is considerably lower than we expect when considering the 40-volt battery pack.

This weed eater also features a variable speed control trigger, allowing gardeners to boost power to the machine when they encounter a tough spot of grass.

There are also some reports of users encountering issues with dysfunctional battery packs as well. If you have any problems with your machine after purchase, contact the manufacturer or dealer for a replacement.

  • Lightweight and compact
  • Comes with a 40-volt battery
  • Variable speed operation for better user control
  • Compatible with other 40-Volt Greenworks battery packs
  • Low runtime, with some users reporting as little as 20-minutes on a charge
  • User reviews reveal some quality control issues with the machine

Earthwise LST02010 Battery-Powered Weed Eater

This machine is the ideal battery-powered weed eater for small gardens. The lightweight and compact design of the Earthwise makes it easy to maneuver. It’s the perfect machine for seniors that enjoy gardening, as it’s easy to use, and the lightweight nature of the weed eater causes less operator fatigue.

The 4.4-lb weight of the machine and the 10-inch cutting range prove our point about this machine being for smaller gardens. The battery pack provides enough charge to run the weed eater for up to 20-minutes, which is more than enough run time to trim a small yard.

This weed eater is also remarkably affordable. While we still prefer the Worx as our value choice in this review, it might be too much machine for a small garden to handle. If this is the case for your home, then this little beauty will do you fine instead.

  • Lightweight for user-friendly operation and comfort
  • Excellent value for money
  • Adjustable height handle
  • Good for small lawns
  • Minimal run time of 15 to 20-minutes on a single charge

Worx WG 184 Battery-Powered Cordless String Trimmer

Worx cracks our review list again with the WG184 model. This model is the big brother to our value pick in this review. With the Worx WG184, you get a double battery, prolonging the run time of the machine.

Worx introduced a fast-charging system for this machine, and the total charge time on this weed eater is nearly as fast as the Makita, which has a considerably higher price tag.

With the Worx WG184, you get all the functionality and features of the Worx WG163 Battery Weed Eater, with additional battery life, and a fast-charging system.

  • Affordable price tag
  • Powerful motor with high cutting speed
  • Powerful cutting operation suitable for long grass
  • Extended battery life
  • 3-year warranty
  • Not suitable for landscaping use

DeWALT DCST925M1 Battery-Powered Weed Eater

DeWALT is back again with another top-quality model for this review. If you like the Worx WG 184 Battery-Powered Cordless String Trimmer, but want a model from a premium manufacturer, then we recommend you go with the DeWALT DCST925M1 Battery-Powered Weed Eater.

This machine has all of the features and functionality of the Worx. However, it runs on a single 4.0aH lithium-ion battery, instead of the two 2.0aH batteries in the Worx model.

Therefore, gardeners can expect the same cutting rpm and run time with this machine, but this model won’t be able to provide the gardener with the same power as the Worx model when cutting through tough grass in the garden.

However, the weight and balance of the DeWALT are far superior to the Worx, which is one standout point that makes this the more attractive machine of the two. That is until you look at the price tag.

  • A premium brand with an excellent reputation
  • Excellent build quality and design with top-quality components
  • Lightweight and compact
  • 13-inch cutting width
  • 3-year warranty
  • A tough choice between this model and the Makita for the best premium model

Black & Decker LSTE525 Battery-Powered Weed Eater

This unit is the bigger brother to our top choice in this review. With this machine, you get two 1.5aH batteries, providing a total run time of around 30-minutes depending on the terrain you’re cutting.

This model is similar to the Worx WG163 in cutting width, voltage, and price. However, we feel the Worx provides a better run time and operation between the two machines.

However, as with most other Black & Decker power tools, it sports a long service life and quality components that make it a pound heavier than the Worx.

  • Excellent functionality and features
  • Affordable
  • Versatile dual trimming and edging function
  • Batteries are interchangeable
  • Comes with two battery packs
  • Low run time of 10 to 15-minutes

Ryobi RY40204 Battery Powered Weed Eater

The Ryobi RY40204 2016 model is an example of junk for sale. While the Worx is a great value machine, the Ryobi is nothing more than cheap.

The unit doesn’t come with a battery pack or a charger, and gardeners will have to buy these spares separately. It also has a short string length, and we feel its underpowered as well. User reports state that Ryobi is not very good at honoring its warranty as well.

However, we felt we needed to include this model in our review to show readers an example of what not to buy. We suggest you go with the Worx if you’re looking for the most affordable model for a medium to large yard.

  • Cheap build and design makes it an affordable choice
  • No battery or charger included with the unit
  • User reviews report early burnout of the motor
  • A short cutting string length

Battery Powered Weed Eater Buyer’s Guide

If you need a little assistance with selecting the best battery powered weed eater, then review this buyer’s guide section. The functionality and features of weed eaters can be somewhat overwhelming, especially for first-time buyers.

In this section, we’ll unpack everything you need to know to help you make an informed decision when selecting the best battery powered weed eater for your yard.


The first factor you need to consider when selecting the best battery powered weed eater for your yard is the weight of the machine. The weight of the weed eater determines the user-friendly operation of the weed eater.

Lightweight machines are easy to maneuver, and you can get them into tight spaces. A lightweight weedeater also reduces the stress on your arms during operation, allowing you to trim for longer before feeling tired.

The heaviest part of the machine is the battery pack. Remove the battery pack, and you’ll notice that the weed eater feels unbalanced in your hands. Most manufacturers take the weight of the battery into account when designing the machine.

As a result, you get a lightweight machine that’s comfortable to operate. It’s also one of the primary reasons why you should never swap battery packs with another brand. The other brand might have a battery design that affects the user operation and comfort of handling your machine.

Weed Eaters are also known as String Trimmers

Machine Power

When assessing your battery powered weed eater, take a look at the power output. Most models will have an operating voltage of at least 20-volts. 40-volt models offer you more power, but they often drain the battery faster as well.

If you do want a higher power machine, it’s advisable to get a spare battery, especially if you have a large yard, and you plan on trimming for more than 30-minutes.

Manufacturers measure battery output in ampere-hours or amp-hours, with top manufacturers offering maximums of 5-Amp-hours in their machines. Those gardeners wanting to cut tough grass or weeds should consider investing in a weed eater that has a minimum power output of 5-Amp-hours.

Feed Reloading Features

The line feed also makes a difference when selecting your ideal battery powered weed eater. There are a few different models to choose from concerning the line feeding features of the machine.

Before selecting your preferred line feeding mechanism, make sure that you understand that the thicker gauge line lasts longer, requiring less need for replacement than the thinner gauge line.

The common types of line feeding mechanisms in weed eaters are the following.

  • The Manual Feed – This is the type all gardeners should avoid., Why feed the line manually when you can let the machine do the work?
  • The Bump Head – This system is a popular line feeding mechanism found in many weed eaters. The user bumps the cutting head against the ground, and the machine automatically feeds the line into the cutting head.
  • Auto-off Feeds – This mechanism feeds line into the cutting head when you switch the machine off.
  • Automatic feeding – This is the best option. The machine detects when you’re low on cutting line and automatically feeds it into the cutting head.

Battery Powered Weed Eater FAQs

Here are a few commonly asked questions we get concerning purchasing the best battery powered weed eater.

How Does a Battery-Powered Weed Eater Work?

Weed eaters have a cutting head that spins at high rpm. The cutting head has two line ports which feed cutting line into the cutting head at a specific length. Some weed eaters feature dual cutting and edging functionality.

The machine receives its power source from lithium-ion batteries. The batteries are rechargeable, with an average service life of 5-years.

What is the Best Brand of Battery-Powered Weed Eater?

All of the brands mentioned in this review are worthy of mention, apart from the Ryobi. Makita and DeWALT are renowned as the premier DIY power tool brands in the world.

What’s the Average Service Life of a Weed Eater

Most battery-powered weed eaters don’t require much maintenance. The most gardeners will have to do for general maintenance is to replace the line spool from time to time, and keep the machine clean. If you experience any issues that are not related to your battery, then take your weed eater to your local dealer for a service or repair.

Most of the problems that occur with battery-powered electric weed eaters are due to issues with the battery pack. Lithium-ion batteries last a long time, but they can be somewhat dysfunctional in some cases. If you have any problems with your battery, and it’s still under warranty, ask your manufacturer for a replacement.

As mentioned, most lithium-ion batteries have a service life of 3 to 5-years. After this time, you’ll need to replace it with a new unit.

Can I Swap My Battery Pack with another Brand?

While many machines will operate using battery packs from other brands, we recommend you avoid this practice. Using another brand’s battery pack may damage your weed eater. The design of the battery pack may also affect the balance of the machine in your hands during operation, leading to injury.
