Have you been putting off weeding? Help is at hand with the best electric weed eaters. They’re a fast, convenient way to eliminate weeds and keep your yard looking at its best. Best of all, this frees up your time for more rewarding gardening jobs, or simply for admiring the view.

Not only are weeds unsightly, but if left to their own devices, they can spread quickly and steal water, nutrients, and sunlight from your favorite plants. If you struggle to keep on top of those pesky weeds, investing in an electric weed eater is a practical solution. 

When it comes to figuring out the best electric weed eater for you, we’ve got you covered. We looked for the best tools to keep your garden pristine. We considered features like high power output, a high number of revolutions per minute, and a wide cutting stance for maximum power. Our round-up includes models from top brands including Black + Decker, Worx, and Ryobi. 

In your search for the best electric weed eater, you may come across gas-powered versions. We focused on electric models as they make for a more planet-friendly choice. Your neighbors will thank you as they are much quieter. Even better, you don’t have the hassle of replacing the gas. For these reasons, they’re better suited to your average gardener. 

While gas weed eaters offer higher power, they’re not common in a domestic setting. You’re more likely to see landscapers using them when gardening on a larger scale. Electric-powered options are more suited to tackling neglected plots that are choked with weeds.

1. RYOBI RY40204A: Best electric weed eater overall

A powerful electric weed eater with great battery run time

Specifications

Power: 40 volts
Weight: 5lbs

Reasons to buy

+
Multiple speed options
+
You can alter the cutting width

Reasons to avoid

-
No shoulder strap
-
Will need charging

It’s hard to find a negative about the RYOBI RY40204A and we think it’s the best cordless electric weed eater on the market. It’s powerful, without the limitations of being corded, the battery has enough power to keep you trimming for over an hour and it’s quick to recharge too. It’s also quite light, so it’s not going to put extra strain on your back or muscles.

It doesn’t have the same range of adjustability as other models on this list, so if you need to tailor your weed eater for height or mobility needs, the Black + Decker LST300 might be a better option. However, it does have edging capabilities so you can adjust the head for both trimming and edging your yard.

It also has some nice features you won’t find on any other model on this list. The adjustable cutting width allows you to choose whether to save battery power or quickly breeze over your lawn. The variable speed is also another nice feature that allows you to choose how to trim.


2. Greenworks 21142: Best corded electric weed eater

A durable and eco-friendly alternative to gas weed eaters

Specifications

Power: 10-Amps
Weight: 9.9lbs

Reasons to buy

+
10-Amp motor 
+
No need to charge the battery

Reasons to avoid

-
Cord length is restrictive
-
Shaft doesn't extend

If you’ve got some doubts as to whether an electric weed eater could ever measure up to a gas-powered one, then the Greenworks 21142 deserves a closer look. It is almost double the weight of most electric weed eaters, but that’s because it’s designed for power and durability.

It has an impressive 18-inch swath, so you can cover a greater area quickly, while the dual string means it easily dispatches even thick weeds. The lack of edging features is a bit of a disappointment and this is not a great option for small, hard-to-reach areas.

The Greenworks 21142 offers great value for money too. It’s not the cheapest on the market, but at around $70, it’s still very affordable, especially considering the cutting power it offers. A corded model may be inconvenient for some, but a battery-powered model with this much power would be more expensive.


3. Black + Decker LST300: Best electric weed eater for hard to reach spots

This quiet electric weed eater is perfect for smaller yards

Specifications

Power: 20-volts
Weight: 5.7lbs

Reasons to buy

+
Adjustable
+
Comfortable to use

Reasons to avoid

-
Takes a long time to charge
-
More powerful options available

The Black + Decker LST300 Electric Weed Eater is a versatile trimmer and edger that’s designed to tackle small gardens and hard-to-reach spots with ease. While the battery power is good, there are better battery-powered options for larger areas, like the RYOBI RY40204A.

If you already have one or two battery-powered Black + Decker products then you might find their batteries are compatible with this weed eater too. As the weed eater only comes with one battery and has quite a long charge time, this would be particularly useful. 

The Black + Decker LST300 Electric Weed Eater is both lightweight and quiet, making it a pleasure to use. It also offers the ability to adjust the weed eater, so you can set it to a more comfortable setup for you.


4. Worx WG163: Best premium electric weed eater

Two-in-one weed eater that comes with free replacement spools for life

Specifications

Power: 20-volts
Weight: 5.3lbs

Reasons to buy

+
Comes with two batteries
+
Comfortable to use

Reasons to avoid

-
Takes a long time to charge
-
Expensive

The Worx WG163 is the priciest electric weed eater on this list, but it’s also an adaptable option that comes with a spare battery too. While it does take a while to recharge the batteries, you can keep one charging while the other is in use and swap them out if the first dies before you’ve finished.

The head is adjustable, moving through 90 degrees so it can adapt to a range of terrains. When using the Worx Weed Eater as an edging tool it becomes wheeled for extra ease of use too. 

The patented line-feeding system allows you to feed through more string with the push of a button. With the free replacement spools for life that come with this weed eater, you won’t need to worry about the cost of string replacement either. With the two-year warranty too, the Worx WG163 has been created with longevity in mind.


5. Sun Joe TRJ13STE: Best budget electric weed eater

Sun Joe's budget corded weed eater is lightweight and easy-to-use

Specifications

Power: 4-Amps
Weight: 5lbs

Reasons to buy

+
Light
+
Good warranty

Reasons to avoid

-
Need to replace spools regularly
-
Not as powerful as other models

At just $30, the Sun Joe TRJ13STE is a bargain electric weed eater. It does have less power than the other models on this list, so it’s not best-suited for tough weeds and overgrowth, but it is light and easy-to-use so perfect for lawn trimming. It does have a tendency to work through spools quickly, so it’s worth keeping in mind the cost of replacement spools when deciding whether this model is for you.

The four degrees of cutting is a nice feature that allows you to adjust the weed eater to the terrain you need to trim. The 13-inch swath is a good cutting swatch, but it is smaller than that of other models like the Greenworks Corded String Trimmer. The cord can be a bit inconvenient, but the cord hook is a nice little feature that helps keep it out of the way.

As a budget model, it’s not going to be especially powerful, but it still manages to offer a good range of features and a two-year warranty. It’s not a great option for anyone looking to take on a big yard clearing project, but it can trim across a variety of terrains with ease.


Are electric weed eaters any good?

If you’re looking for a fast, effective way to keep your yard a weed-free zone then a weed eater is a solid investment. They help take the hassle out of weeding so you can relax and enjoy your garden. The best electric weed eaters boast high power, with some models providing around 40 volts. This means the device can handle an hour’s worth of weeding. Compared to gas weed eaters, they’re much quieter and so can keep your garden feeling like a tranquil haven. 

If you’ve tried a gas weed eater in the past, you may have found it cumbersome to use. You’ll be pleased to know that electric weed eaters are much lighter, with the average machine weighing in at about 5lbs. This is because they don’t have a tank of fuel attached, unlike their gas counterparts. As electric weed eaters are lightweight, they are much easier to use for long periods. 

If you’re looking to do your bit for the planet and save yourself money, then an electric weed eater is a great option. Unlike gas models, they don’t rely on fossil fuels. They also offer great value for money with the average model costing around $70. Plus you’ll have none of the fuss of buying replacement gas.  


Gas vs electric weed eaters

What’s the difference between gas and electric weed eaters? You’ll typically find gas weed eaters in a professional gardening setting. This is because landscapers are working on a much larger scale and may need to tackle extremely overgrown plots. In this scenario, the power of a gas weed eater is necessary to blitz established weeds and last all day.  

If you’re looking for a device for everyday use at home, then we would recommend choosing an electric weed eater. They’re lightweight which makes them easy and convenient to use and you don’t have the hassle of topping up the gas. They produce zero emissions so are far more planet-friendly than their gas counterparts. Electric weed eaters are much quieter so can keep your garden feeling peaceful and avoid disturbing the neighbors. They help you fast-track your way to a tidy yard meaning you have more time to sit back and enjoy it.



Cordless electric weed eaters vs corded

Corded electric weed eaters provide you with constant and consistent power without having to recharge your machine. They are quite often a lot lighter too as they haven’t got the added weight of a battery. However corded weed eaters don’t give you as much flexibility in terms of reaching the furthest place in your garden. More often than not, corded models require the purchase of an extension lead – particularly if you have got a large and lengthy yard to clear. 

Cordless electric weed eaters give you more mobility. You can travel far and wide to rid your weeds with this type of battery-powered gadget because you aren’t limited by a cable. However cordless electric weed eaters can often be a bit heavier than their corded counterparts. That’s because they have the added weight of the rechargeable battery. 

Some cordless options also have lengthy battery charge times so watch out for that. Plus if you forget to recharge the battery before using your outdoor power tool, this can be a pain. Due to the fact you are running on battery – rather than mains power – you also have a limit to your cutting time. 


What to look for in an electric weed eater 

There are plenty of options when it comes to purchasing a good electric weed eater, but it’s crucial to decide on a model that’s suitable for you. That includes looking at the design and working out if it’s lightweight enough for you to carry around for as long as you’d like, especially if you have any issues that might impact your strength. 

You’ll also want to decide on power options depending on how big your garden is, and amp up the power if your garden is larger. Warranty is another thing to bear in mind, as though an electric weed eater won’t break the bank, you don’t want to be lumbered with a model you can’t replace or get help with.


Electric weed eater power and battery

One of the most important things to consider when purchasing an electric string trimmer is if it has the power you need to accomplish the type of work you do. We looked for weed whackers that have high amps for corded models and high-voltage batteries for cordless ones. 

The more power a weed trimmer has, the tougher the grass and weeds it can tackle. We evaluated and compared cordless and corded electric string trimmers and found that regardless of the power source, if you choose a trimmer with enough power, you can trim efficiently.

When choosing between a corded and cordless weed eater, consider the type of work you need the trimmer to do and the size of your yard. Buying a trimmer that requires an extension cord limits your mobility, but that may not be a problem if you have a small yard. 

The advantage of using a cord is you don’t have to worry about the battery eventually dying and needing to be replaced. However, a cordless trimmer gives you limitless mobility, so it’s likely the best option if you have a large yard or need to trim in a remote location.


Maintaining your electric weed wacker

While electric trimmers don’t require nearly as much maintenance as their gas counterparts, there are things you can do on a regular basis to keep them running well for an extended period. Kristi Howard, of Black & Decker Outdoor Products, says that a common problem with electric string trimmers involves people using the wrong gauge of extension cord to power them. Howard says you should be sure to use an extension cord that is heavy enough to carry the current your product will draw.

“An undersized cord will cause a drop in line voltage resulting in loss of power and overheating,” Howard explains. “When in doubt, use the next heavier gauge.” She says the letters WA on the cord jacket indicate a cord that is suitable for outdoor use. Regarding corded versus cordless trimmers, Howard feels they are comparable in terms of power. Corded trimmers are generally less expensive than battery-operated trimmers and are easy to maintain, but they have less mobility. 

To properly maintain an electric trimmer, Howard suggests checking for damaged parts and cleaning off the air intake slots before each use to avoid overheating. She says you should never immerse an electric string trimmer in water or clean it with a pressure washer, and you should store it indoors, out of reach of children. “Keeping your trimmer regularly maintained should minimize your need for larger repairs,” Howard adds.
