It is true that any weed eater that is powered by anything other than a cord can be considered ‘cordless.’ But for this post, any time we refer to a cordless weed eater, we mean a battery powered weed eater.  And while we don’t consider the Stihl weed eater, the best “battery powered” weed eater, we do offer our review of the Stihl weed eater in our Gas powered weed eater reviews.


Best Overall: Worx WG184

Worx WG184 40V (2.0Ah) 13' Cordless Grass Trimmer/Edger with in-Line Edging, and Command Feed, 1 hr. Dual Charger, 2 Batteries

  • Lightweight and easy to maneuver
  • Pivoting cutting head makes navigation a breeze
  • Two 20-volt batteries that can be used simultaneously or separately
  • Variable speed control (usually only found on gas trimmers)
  • 2-in-1 use – trimming and inline wheel edging


    • Premium performance comes at a price.
  • The Command Feed button is generous and you may feed more string than you intend. Once you get the hang of it, you’ll be able to control it better.



The Worx brand is well known throughout the lawn care community, and they have a reputation for bringing quality products that do more than last a long time. They provide amazing high quality products.

The Worx WG184 is a precision weedeater propelled by 40-volts of power with two lithium-ion batteries (both included) that provides an ample amount of power.

They don’t skimp on battery life either. It’s stated to be able to complete yards as large as half an acre, with many reviewers saying they can complete yards measuring a full acre.

That’s all in one charge.

You’ll also love the variable speed control and the easy command feed spool system. Perhaps my favorite is the ability to swap from trimming to inline wheel edging seamlessly.

All it takes is a bush of a button.

The Verdict

It is understandable if you don’t want to spend a lot of money on a tool that isn’t going to be used for extended time intervals. But if you want the most professional looking lawn, without lugging around those bulky and cumbersome gas weed eaters… Well, this is where your search ends.

Runner-up for Best Overall: Greenworks 13-inch Cordless Trimmer

Greenworks 13-Inch 40V Cordless String Trimmer, 2.0 AH Battery Included 21302

  • Battery and Charger are included (make sure you select the option specifying that)
  • Extremely lightweight
  • Battery balances out the weight of the rest of the weed eater
  • Compatible with multiple Greenworks battery models
  • Pivoting head makes controlling where you trim easy and effortless
  • Used as a trimmer and wheel edger
  • 40-volts of power and 2.0 AH battery offers up to 60 minutes of battery life
  • Tough and durable machine


  • The stock string isn’t great.
  • Command feed doesn’t work well with the included string, but all is solved with new string/line.



If you don’t want to pay top dollar for a battery operated weed eater (I understand why someone wouldn’t), but you still want a highly capable tool.

You’ll probably be interested in this Greenworks model. It offers the same 40-volt battery (which is included), and the same 13-inch cutting deck as the Worx model.

If lightweight products are your thing, then this is perfect for you.

Weighing less than 10 pounds, anybody can handle using this. And since it is battery powered, there is no added idling weight. If your looking to save some money Greenworks is a solid choice:

The Not So Good

The biggest complaint with this device is the trimmer line that it comes with. The line shipped with it doesn’t seem to feed very well, and the command feed doesn’t work much at all with it.

Thankfully, it is easily remedied by purchasing a new line (something you’ll need to do eventually anyway).

The Verdict

This product offers excellent power, and sufficient battery life (especially for a cordless model), but does lack an easy spooling method. Instead of utilizing a bump spool, or command spool, it opted for an automatic one.

You’ll find yourself starting and stopping the weed eater to extend the cord fairly often. This means weed eating is going to take a little longer than you might expect it to.

Versatility on a Budget: Black and Decker LSTE523

BLACK+DECKER LSTE523 Li-On String Trimmer

  • Lightweight – 6.3 pounds total
  • Fairly priced for a respectable amount of power
  • Black and Decker warranty
  • EASYFEED spooling system offers one-touch control
  • 2-in-1 system for trimming and edge wheel capability
  • Variable control for longer run time or more power
  • The battery is lower capacity than some other options.
  • Lower power at 20V than other options.
  • Not great for very large yards.
  • Some owners think using the trimmer as an edger doesn’t work very well.

Black and Decker’s tools seldom let you down. You can always expect quality performance at a manageable price.

That has never been more obvious than it is with the LSTE523. You’ll like the price tag (especially if you catch it on sale) and you’ll be more than happy with the results too.

This model converts from a weed eater to wheeled edger, giving you multiple uses for it. But perhaps more impressive is the variable control that it offers, allowing you to increase the runtime or add some extra power to the machine. The choice is yours.

I also enjoy the Black and Decker EASYFEED system that advances the line using a button. This is much easier than a bump spool and way more efficient than an automatic spool. This weed eater is simple to control too, weighing well under seven pounds you’ll never worry about arm fatigue again.

The Verdict

If you want something that is versatile and doesn’t leave you strapped for cash until your next payday, this is a weed eater you could use. Don’t expect perfect edge lines from it, but if you aren’t too anal about your lawn anyway, then I think you’ll enjoy the results you get from the Black and Decker LSTE523.

Budget: Black and Decker LST300

  • Automatic spooling
  • 2-in-1 design – edger and trimmer
  • Longest run time in its class
  • Weighs less than 6 pounds
  • Incredible Price


    • Feels like a budget option.
  • Shorter battery life than other options.



Looking for the lowest price product is never easy when you’re also trying to get quality.

Thankfully, Black and Decker made a model with that specific thought in mind.

This model offers an automatic feed spool, and it can still be used as a trimmer and edger.

It even offers the longest runtime than any other cordless weed eater at its price point.

The Not So Good

The unfortunate reality of looking for budget trimmers is that you have to forego the highest quality parts for cheaper ones. This means you don’t get a professional looking lawn, and you may have to purchase another one down the line.

However, this product is no slouch. You’ll still have a respectable lawn, and you get the added benefit of saving hundreds of dollars.

The Verdict

Those of you with very small yards, and not a lot of weeds, will benefit from this Black and Decker weed eater. If the price is your biggest concern; this model is a no-brainer. It is lightweight, easy to control, and the best product at this price.

Why Cordless Weed Eaters

If you are reading this, it is likely that you already understand why cordless weed eaters are objectively better than trimmers with cords. But the benefits of cordless weed eaters go far beyond the fact that there isn’t anything tethering you to an outlet.

Freedom of Movement

If you want your lawn to have that finished, well manicured look, you can't be lazy and not trim around trees, posts, or along your sidewalk. A string trimmer or weed eater is the perfect tool for the job.
If you want your lawn to have that finished, well-manicured look, you can’t be lazy and not trim around trees, posts, or along your sidewalk. A string trimmer or weed eater is the perfect tool for the job.

The obvious benefit of this is you can go anywhere you need to go without having to manage the cord while doing so. Furthermore, you’ll never have to worry about getting cords tangled around your bushes or delicate flower gardens being trampled by them.

One not so obvious reason that cordless trimmers are better than their corded counterparts is that you will never need to worry about what type of power cord to get for your trimmers.

But what does that even mean?  Each weed eater is powered by a motor, and certain motors run more efficiently when partnered with cords with specific gauges. This doesn’t necessitate that you get the exact gauge recommended for the weed eater. But it does mean that its possible your motor lasts longer if you do so.

No Toxic Fumes

To be fair, gas weed eaters are also cordless ones, but as I stated earlier, I’m talking only about battery powered weed eaters today.

Weed eaters fueled by gas give off unpleasant odors and sometimes even downright dangerous fumes are emitted from them. The worst part is, the motor is often only a few inches away from your face, making it nearly impossible to get away from those fumes.

Electric weed eaters have none of those problems. With a cordless trimmer, you can put away your breathing mask and enjoy the scent of freshly cut grass that we all love so much.


Cordless weed eaters aren’t as powerful as gasoline propelled ones, but they are much stronger than weed eaters that need to be plugged in. There is nothing quite as frustrating as the trimmer line getting caught on the weeds you’re trying to cut down. Battery operated trimmers usually have more powerful motors, so it is something that you probably won’t ever experience if you keep up with your lawn regularly.

Light Weight

Cordless trimmers are always going to be lighter than trimmers that use gasoline. The motors are smaller, there are less moving parts, and there is no tank attached to house the fuel.

If you are looking for something lightweight, then you should be looking for a cordless weed eater.

Challenges of Cordless Weed Eaters

Most of you reading this already know that you want a cordless weed eater. But that doesn’t mean that everyone who is reading is going to benefit from a cordless weed eater. There are some frustrations that you may have if you purchase a wireless trimmer, and these frustrations are going to be amplified if you aren’t the right candidate for a cordless weed eater.


Cordless weed eaters (particularly the more powerful ones) tend to cost quite a bit more than gas-powered, or weed eaters that use extension cords. The fact is, this technology is pricier than most other types of yard trimmers.

We can assure you, the comfort and ease of use you get with these are well worth the initial price tag. But if you are looking for the cheapest possible solution, these models may not be for you.


Earlier we mentioned weed eaters operated by batteries are more powerful than those that require a cord going from your outlet to the tool itself. But if you need extreme amounts of power output, then you should probably look into getting a gas powered weed eater. This usually is only the case for those who do landscaping work as their profession though.

Most of us using weed eaters strictly for residential reasons are fine with battery operated trimmers.

Battery Life

As with anything that is powered by batteries, you only have a limited time before you need to plug in your battery a let it recharge. Many manufacturers of cordless weed eaters remedy this by shipping two batteries with their product. And if they don’t, you could always purchase another one if need be.

If you have a giant yard that takes a lot of time to weed eat, then you may be better off purchasing a gas powered weed eater.

The second aspect of battery life is how long the battery lasts before you need a new one. If you’re buying batteries every six months to a year, then you aren’t saving any money on gas. Instead, your simply spending that money on batteries for your weed eater.

Make sure you get a weed eater that comes with batteries that will last a few years. At the very least, make sure they have a warranty for their batteries.


When it is time to do yard work, you want to know that you have the tools at your disposal to get it done correctly. And weed eaters are one of those tools. Today we showed you four of our favorite cordless models, and we’re confident one of these will fit your needs. But if you’re still undecided, and need a little nudge, I’ll help you out.

Our top pick for a cordless, battery-powered weed eater is the Worx WG184 (See latest price on Amazon). The battery life is unmatched, and the power almost rivals the power of gas trimmers.
