Every lawn needs a good weed eater. And when it is cordless, work is effortless, since you have the reach and the maneuverability of trimming hard-to-reach areas.

Battery powered weed eaters require less maintenance compared to their gas counterparts. With the turn of a button, the tool is up and running. Some string trimmers also double as edging tools. They make it easy to complete trimming and edging in the shortest time.

In Short

In today’s list, we are talking about weed whackers that cut your trimming time in half. If your lawn needs whacking, and you want an ideal tool for most tasks, the Ego Power+ ST1502 has got your back. It can take care of acres of land impeccably and in a short time.

We have also listed gas-powered models for tough jobs. Our winner is Husqvarna 128LB. It is ideal for commercial landscapers thanks to its 28cc engine. It can deal with tall grass and thick weeds before you go in with a mower.

  • Thick, dual twist line
  • 15-inch cutting swath
  • Durable aluminum shaft
  • Speed trigger control
  • Powerful 56V lithium-ion battery

A completely balanced tool, Ego Power+ ST1502 is perhaps the most comfortable yet powerful string trimmer. This model will cut through thick grass and can even deal with Japanese Knotweed that’s up to one inch thick.

It couples a 56V battery and a brushless motor to perform its job efficiently. The motor delivers faster-cutting speed making it possible to create a 15-inch cutting swath with no problem. If you have an overgrown lawn and don’t want to deal with gas and oil, you will love the convenience presented by this string trimmer.

The variable speed trigger is a nice addition since you can increase and reduce the speed according to the power you need. When the tool is around delicate flowers, and you don’t want to harm them, a moderate speed will help you out.

When you need blasting speeds for invasive weeds, the highest speed gets the ST1502 cutting with no fuss. It is fast, efficient, and the kind you pick when you have a large property to maintain in peak condition.

What’s not to like about a weed whacker that is not noisy like other models. It’s tolerable, noticeable yes, but no one will be shouting at you to turn down the noise. Most people compare the noise to that of a blow dryer. It is a significant change if you are used to gas-powered string trimmers.

This model uses the advanced, dual, 0.095” twist line. It is a professional-grade string that is 20% thicker. It cuts longer, meaning you won’t be making replacements any time soon. With a solid shaft and trigger control, it is easy to trim over hedges. Every area of your property should be pristine with the same tool.

We like how comfortable it is since it has a soft grip. If blisters make you cringe at working on your lawn, this one offers you comfort that will get you working with your worries aside. You will also find that the weight is balanced since the battery is on the rear while the head is at the front.

This is not the cheapest lawn trimmer. The batteries are expensive to replace. It is a professional-grade tool, so you should consider whether it is an investment worth making.


Ego Power+ ST1502 stands out from the competition. It is efficient in so many ways including a dual line that is not eaten up fast. It can deal with notorious weed and thick grass while getting to all the awkward places your lawnmower can’t. With its edging capabilities and powerful battery, it’s going to take a lot to pass up this string trimmer.

2. DEWALT DCST990H1 Review "A Battery-Powered String Trimmer for Commercial Use "
  • Gear drive design
  • Brushless motor
  • Metal case housing
  • The handle is removable
  • Dual string design with either 0.08 or 0.095-inch diameter string
  • Variable speed trigger with two-speed settings
  • Efficient bump feed mechanism
  • It is a bit heavy and expensive
check price

If you are looking to replace a gas string trimmer and wondering which model to pick, DeWalt’s DCST990H1 may be for. It comes with a powerful 40V battery that performs as well as some of the gas trimmers. It gives you more than enough runtime to complete demanding jobs on time.

You shouldn’t worry about the size of your overgrown lawn. This tool allows you to finish work in the least passes and in record time. This DEWALT tool has a 15-inch cutting path – a godsend for professionals and large property homeowners.

Its brushless motor is energy efficient, ensuring that you get the most power out of your string trimmer. You will notice it is large and takes most of the space on the handle. This allows for more torque without decreasing the life of the tool. Because fewer parts are moving, the friction generated is smaller.

The speed trigger is close to your fingertips, which allows you to adjust the speed as you wish. The DCST990H1 has an exclusive gear drive design. The gear drive design allows you to power through thick shrubbery, long grass, and debris without jams. The dual string line offers durability and improved performance if your lawn tends to be invaded by weed every once in a while.

We like that it comes with all the necessities including the guard already installed in the motor. It is appealing in the sense that the metal case at the top protects the motor and the gear drive to increase their longevity.

With the battery in the trimmer, this tool is well-balanced. It comes with a support handle that gives you more leverage. It is still a bit heavy at 13.9 pounds. Working for a long time may be tiring since the tool will put a strain on your back and hands after a while.

You can use the DCST990H1 as an edging tool by turning it slightly to the side. It has a guide wheel that helps you make clean and straight edges.  The bump feed mechanism works efficiently to provide you with smooth work.

One issue with this weed eater is the price. Notice that we did not recommend it for residential use. As such, it is not ideal for small homeowners.


DEWALT DCST990H1 is one of the top performing string trimmers on the market. It prides itself on improved torque, over an hour of run time, and adjustable speeds. It can trim and edge efficiently, which is why many users forgo gas-powered models for this one.

If you want an alternative with more power and the ability to use different batteries, then think about the DEWALT DCST970X1 FlexVolt 60V.

3. Ryobi One+ 18V Review "Best for Small Homeowners "
  • Gets into tight locations
  • It has a speed trigger button
  • Comfortable handle
  • Compatible with different types of batteries
  • Simple to convert to an edger
  • Rotatable shaft
  • It does not come with a battery and a charger
check price

Ryobi ONE+ is a relatively compact string trimmer. That’s why it is recommended for small homeowners. It can get to the tightest places thanks to the 10-inch cutting swath. It is a flexible weed eater that allows you to use many batteries, including the ones from the Ryobi One+ line.

You will notice that assembling the Ryobi ONE+ is straightforward. You won’t waste a lot of time between receiving the tool and starting to work with it. The handle may be hard to adjust, but once you get the correct angle, working with this tool becomes second nature.

This weed whacker comes with a speed trigger. It is unique since not many string trimmers in its price range include such convenience. With the guard, it is easy to trim and edge around delicate plants. The head of this tool swivels, which allows you to create straight edges that portray a perfectly manicured lawn.

The 18V lithium-ion battery will last for around 20 minutes. Compared to bigger cells like WORX WG160, which we’ll review later, it is a considerable time. Since it is designed for small homeowners, you will find that the work time it offers is adequate.

Ryobi ONE+ uses the regular single line that is 0.065 inches thick. It has an automatic feed that eliminates a bump feed mechanism. Changing it is easy since it uses Reel Easy trimmer heads that are installed using a reel handle. A fast replacement gets you back to the job quickly, and it allows you to finish your work in good time.

The battery goes into the back of the handle. As such, this trimmer keeps its balance and saves you from fatigue. It allows you to work without having to worry about muscle cramps.

Ryobi ONE+ doesn’t come with a battery and a charger. If you don’t have a spare battery, you will have to buy a new one. NiCad cells are cheap but not efficient. Lithium-ion batteries are expensive, but they have a long shelf life and a longer running time.


Ryobi ONE+ is a small, lightweight string trimmer that is useful to small homeowners. If you trim grass regularly and have areas that are hard to reach with trimmers that have wider cutting paths, this one will do just fine.

Ryobi also offers a more powerful and versatile model; the Ryobi ONE+ 40Vcordless string trimmer.

4. Black + Decker LST136 Review "Best 40V Cordless String Trimmer "
  • Can cut through thick grass
  • Height-adjustable shaft
  • Powerful battery with a long lifespan
  • PowerDrive Transmission system
  • Automatic string feed that works efficiently
  • PowerCommand Dial to increase runtime or power
  • String advances faster than on other cordless string trimmers
check price

Black + Decker LST136 40V is a popular model. It boasts high power and affordability for homeowners and for commercial use. If you are a landscaper, you will benefit from a string trimmer that brings out an inviting lawn for your clients.

Whether you are working on small paths or around your home, Black + Decker LST136 cuts faster and edges better than other models. It is a top consideration for most people.

We like that this weed whacker comes with a PowerCommand dial that allows you to choose between MAX power and MAX runtime. The PowerCommand feature lets you spend less time on longer growths. But, it also allows you to work longer to perform finishing touches on short grass.

You can get up to 60 minutes or running time on the lowest setting, while the highest setting provides only 20 minutes. The medium setting, which is the normal mode, gives you 25 minutes. You will want to choose the mode each time to get the most from this string trimmer.

A 40V MAX lithium ion battery and a 13-inch cutting swath make your work way more manageable if you need to cover a wide area. It uses the AF100 string trimmer line that advances automatically. The trimmer line allows you to work continuously, without interruptions.

To turn this trimmer into an edger, you only have to press a knob while twisting the cutting head. You don’t need two power tools to complete work in one session. With the guide, you will be able to cut in a straight line making it effortless to achieve an appealing garden.

At 7 pounds, this is one of the lightest string trimmers. You can avoid back pain and hand fatigue since the shaft is height-adjustable. The auxiliary handle also comes in handy to offer more control in the way you handle the trimmer. Since it has no vibrations, the LST136 is a comfortable tool that works exceptionally well.

This string trimmer, however, uses string faster than other models in its class. Replacing the string could get annoying since you will have to do it often.


If you are a suburban homeowner or a landscaper, this string trimmer might be exceptional for your needs. This includes general lawn trimming. But if you live in the backcountry, this model is not powerful enough to fulfill your needs. Its 40V battery and motor are useful for thick grass, thin shrubbery, and fresh growths of weed.

5. Milwaukee Electric Tools M18 2725-21HD Review "Best for Professionals "
  • 14 or 16-inch cutting path
  • Can trim thick shrubbery
  • Variable speed trigger
  • Battery and motor balance on the handle
  • Up to one hour of running time
  • Comes with a support handle
  • Dual string line
  • Can reach full throttle in a second
  • Does not have an edging option
check price

The Milwaukee M18 provides enough power to cut grass and clear shrubbery. Designed with professionals in mind, this tool balances performance and maneuverability to give you incredible productivity.

This string trimmer uses the M18 battery platform. It can run on any of Milwaukee’s batteries, even on the 9Ah one. This battery gives you up to one hour of runtime for cutting grass. The speed trigger allows you to switch from 4,600 to 5,800RPM. The battery life decreases at the highest setting, but it’s ideal for cutting thick bushes.

Milwaukee 2725 21HD comes with a dual string design. It will accept a 0.08” or a 0.095” diameter string. You will get the 0.08-inch string preinstalled with the new model. The cutting swath is either 14 or 16 inches. When you want to clear a wide area, a 16-inch swath will do it for you. When you need to get to hard-to-reach places, a 14-inch swath will do it perfectly.

This trimmer doesn’t have an automatic feed mechanism. It comes with a bump feed mechanism, which is efficient. It has a metal ring that is useful in maintaining the durability of the plastic parts. This trimmer won’t wear and tear as fast as the other bump-feed string trimmers.

You get an adjustable guard that allows you to select the ideal length when cutting around gardens. The over-molded grip on the main handle and a rubberized support handle make this tool easy to use over long periods of time. We find that it has little vibration that is barely noticeable.

So what’s not to like? The shaft and line cutter are adjustable. An onboard lever or something similar that allows us to make adjustments would have been a nice addition. Besides the missing onboard lever, the Milwaukee 2725 21HD doesn’t have tool storage. If you want to make adjustments, you will either have to bring your tools with you or do it before you start working.


Milwaukee 2725 21HD is a remarkable outdoor power tool. It will give you hours of life and power when you need it most. With its 9Ah battery and a brushless motor, it combines some of the best features that make lawn maintenance enjoyable and less of a chore.

6. Makita XRU09Z 18V x 2 LXT Review "Midrange Trimmer for Small Lawns "

  • Both batteries charge at the same time for only 45 minutes
  • Up to 60 minutes of battery life at low setting
  • The brushless motor lasts longer
  • LED battery indicator
  • It is heavier than other 36V string trimmers
check price

Outdoor power equipment continues to change rapidly. And when it comes to working more efficiently, battery-powered options take center stage. Makita brings us the XRU09Z cordless string trimmer. It is not the most powerful our list, but neither is it underpowered.

If you have a small or medium-sized property that you want to trim in a short time, you will want more power than the other residential weed whackers offer. This model offers 36V of power by combining two 18V batteries. Makita balances the weight by placing the batteries side by side on the top end of the handle.

The batteries are efficient for most tasks since they can give you an hour of battery life. The speed trigger facilitates this feature. This way, you can trim short grass on mid-sized lawns for an extended period of time.

You can dial in the ideal handle length. For most people, it is an advantage since it lessens the backache. It may, however, not be of much help if you are over 6’2 because it won’t extend further to cover your height.

The guard prevents the clippings from reaching your eyes, but you should always wear protective glasses and clothing. The Makita XRU09Z is easy to control. You will only have to adjust the guard and advance the string by bumping the tool.

Unfortunately, there are times when the string won’t advance even when you bump the tool. Reloading the string can also be a hassle.


If you want instant torque, less maintenance, and increased performance for tall growing weeds, the XRU09Z is a good tool. If you want to avoid the problems with the bump feed, you might want to switch it with a different one. However, this model’s power and ease of use allow it to maintain its reputation as a great string trimmer.

With a 20V lithium-ion battery, it can cut a path up to 12inches wide. It provides the power you need for short grass, but you should avoid using it on an overgrown lawn. It is ideal for homeowners with small yards, more so if you regularly do the trimming. Knowing the mentioned facts, you won’t get disappointed if it requires several passes to cut thicker growth.

It will also deal with new weed growth, but not sticks and debris that require gas-powered models. The battery life is around 20 minutes. But it comes with an extra battery, so trimming for 40 minutes seems possible.

We do like that it converts from a trimmer to an edger in seconds without requiring any tools. The dual in-line wheels make it super easy to perform the finishing touches that make your lawn welcoming.

If your lawnmower can’t reach tight areas, this trimmer can do the job instead. You will like that the edger guide also functions as a flower spacer that protects your delicate flowerbeds.

Using this trimmer comes effortlessly. The quick release lever allows you to adjust the length of the tool, which allows anyone to use it without experiencing back pains. What’s more, the trimmer head can tilt to 90 degrees in two easy steps.

It gives you an automatic line feed, so you don’t have to deal with a bump mechanism. This allows you to work without interruptions. You get free spools for life. You won’t have to supply your string trimmer, WORX will do it for you.

The battery requires 3-4 hours to recharge, and then you can use it only for 20 minutes. This is a clear disadvantage for busy homeowners. Two batteries may not be enough for a whole session of lawn trimming. Remember that this unit isn’t useful on the overgrown lawn, so adjust your expectations.


If you enjoy owning a beautiful lawn that requires almost daily maintenance, WORX GT 2.0 WG160 may be the string trimmer for you. It has multiple functions that come in handy when the lawn maintenance day comes. It is lightweight, and it gives professional results each time.

Cordless String Trimmer Buyer’s Guide

You’ve decided to maintain your lawn, but you don’t want to drag a massive cord behind you. Cordless string trimmers are an excellent choice, but there are too many of them on the market.

Finding the best one can be a tedious task that could waste a couple of days of your time.

Fortunately, we have spent plenty of time researching cordless string trimmers. We have gathered all of the relevant data and presented it for you.

Types of Cordless String Trimmers

Before you go out and buy a new cordless string trimmer, you need to know that you have two choices.

  • Battery-powered cordless string trimmers: Battery-powered weed whackers are a good choice if you have a small property. They are capable of doing work on big properties, but short battery life is a downside. On the other hand, most of the batteries that come with string trimmers can be used in other devices of the same brand. Another plus is the fact that battery-powered string trimmers aren’t hard to maintain. If you want to avoid gas fumes and you have a small yard, then consider battery-powered weed whackers.
  • Gas-powered cordless string trimmers: If you own a large property, then you might need a gas-powered weed whacker. Some come with a translucent gas tank that allows you to monitor the fuel level. You can find models with a two-cycle engine, which require adding oil to the gasoline. But, you can also find models with a four-cycle engine. You don’t have to add oil to the gasoline if you use a weed whacker with a four-cycle engine. The biggest problems are the toxic fumes and loudness.

Types of Trimmer Shafts

Before you can purchase a new cordless weed whacker, you need to make an important decision.

There are two types of trimmer shafts on the market.Straight shaft string trimmers, and curved shaft string trimmers.

Straight shaft models are common, and you won’t have any problems finding them. They are excellent for reaching under the fence and other tight spaces. Another useful feature is a telescopic shaft. If you need more reach, simply adjust the shaft and you will be good to go. Straight shaft string trimmers are suited for tall people. The design of the shaft allows tall people to do their work without the need to bend over.

Curved shaft string trimmers aren’t as common as their straight-shaft counterparts. Reaching small corners with a curved shaft can be tricky, but it is possible. Curved shafts are good when you want to trim weed and grass in open areas. Short people will find cordless string trimmers with curved shafts easy to use. They allow short people to keep the cutting head at a 90-degree angle to the ground.

String Feed Systems

There are two different systems that feed the string to the trimmer. The bump-feed allows you to tap the head of the tool on the ground, which provides you with more string.

An automatic-feed does all the work for you. As soon as the string breaks off, the string feed system delivers more string out of the spool.

There is nothing wrong with any of the two feed systems, but the string needs to be delivered smoothly. You should look for a weed whacker that has an easy-to-replace spool, or a spool that allows you to easily load a new line.

Consider Before You Buy

Now that you know which type of a trimmer suits you, as well as which shaft is the right one for you, you only need to know a few more things. Consider the following few things, and you will be able to find a good cordless string trimmer.

  • Weight: Your body will bear the full weight of the weed whacker. So, you need to know which weight feels comfortable to you. Consider for how long you will be doing yard work, as well as the weight of the trimmer. Most of the models weigh around 10 pounds, but you can find a couple of models that go far below 10 pounds.
  • Battery life: Most of the cordless string trimmers that use a battery can work from 15 to 60 minutes. The problem is that the battery charging can take from 30 minutes up to two hours. So, an extra battery is a smart investment, but only if the tool allows you to switch batteries.
  • Interchangeable batteries: We have mentioned that some manufacturers allow you to use their batteries in different tools. If you already own a chainsaw and a lawn mower from the same manufacturer, you could think about getting a weed whacker from the same manufacturer.
  • Variable power output: The best cordless string trimmers allow you to change the power output, which influences the cutting speed. You can use low speeds for light-duty work, and higher speeds for intense work. Bear in mind that high speeds drain the battery faster than low speeds.
  • Adjustability: Adjustability of your new weed whacker plays an important role in comfort. Good models allow you to adjust the handle, the cutting angle, and the shaft length. If you cherish comfort during work, look for an adjustable weed eater.
  • Yard size: The size of your yard should play an important role in your choice. Electric cordless string trimmers are great for yards that require little work. On the other hand, if you own a large yard, you will get more work done with a gas-powered unit.
  • Cutting path: Most of the cordless string trimmers come with a 12-inch wide cutting path, which is good enough. But, you should consider the type of work you plan to do. If you will be clearing large areas, go for a cutting path that is 15 inches wide, or more. Contrarily, if you only need to work on tight spaces, then even a 10-inch wide cutting path could be enough.
