  • Battery Size Limits Run Times

Ease of Use

The battery powered weed eater has become a popular choice for many homeowners. These tools are really easy to use: anyone can slap a battery in, and start trimming weeds in seconds.  To use a battery powered wacker, you just need to charge the battery and plug it in to the weed eater.  There’s no smelly, flammable gasoline to deal with, or a long copper cord to haul around.  When it comes to ease of use, the battery powered line trimmer wins by a knockout.  An additional benefit is if you have other battery powered outdoor tools in the same brand family – you can then usually share batteries between them. Just make sure they are the same voltage.


As for power, most battery powered trimmers  aren’t going to overwhelm you and cut down that 5 foot tall nest of weeds in your backyard; but they do pack enough power for most yard needs . The better models will have a 40 watt or higher battery – 80 volt is really the way to go if you can afford it. If you’ve ever used a cordless drill with just 18 volts, you know how underwhelming that experience can be when tackling a tough job it can be.  Since this is a purchase you’d expect to last for more than a couple years, don’t cheap out and buy technology that’s already seen it’s prime.

In 2018 – you shouldn’t settle for any outdoor power tool that’s less than 40 Volts. 80 volts is quickly becoming the norm. If you are having trouble deciding between two equally-matched weed eaters, go with the one with higher voltage. You won’t regret your choice.

Limited Run Time

The main downside to battery powered string trimmers is also it’s advantage: the battery itself. While light, versatile and easy to use, a small power source has it’s disadvantages.

To begin with, a lithium ion battery has a set amount of charges.  Eventually, it will die – especially if you overheat it or run the charge down too low.  This will require you to purchase another battery.  While we’ve written an more in-depth article on battery care that provides a full list of ideas, rotating two or more batteries can help to slow their eventual demise.  That’s what I did then I purchased my Black and Decker last year – I picked up two extra 2amp 40V batteries at the same time.  I also purchased a battery powered mower and blower from Black and Decker to use in my smaller yard – so as long as I remember to charge after usage, I’m good to go.

You are also limited to the amount of usage time per charge.You need to look at the amperage rating of the battery – 2amp rated batteries will last longer than 1 Amp.  Of course, they take longer to charge as well – nothing is free in this life.   Once it’s dead, you need to wait until it charges back up.  As stated above, having more than one battery on hand is really a must if you have a yard of any size.

The battery powered weed eater is a good option if you have a small to medium yard that only needs general lawn care. You could get away with an acre or two with some bushes and small trimming to take care if you have more than one battery.  If you have vines thicker than a pencil to deal with, you probably want to look for a more powerful device.

Our Choice For The Best Battery/Cordless Powered Weed Wacker

BLACK+DECKER LST136W 40V MAX Lithium Ion String Trimmer, 13"
  • The PowerDrive Transmission delivers more power from the motor to the cutting string so you can get the job done faster
  • 40V MAX* lithium battery for long runtime
  • PowerCommand dial to choose between MAX power and MAX runtime

This monster from BLACK+DECKER is head and shoulders above the competition. Loaded with plenty of features that not only sound cool; they are actually useful. It is lightweight for great mobility and comfort.

40 Volt MAX Lithium Battery

One of the most powerful batteries on the market, this one will last longer, and is more powerful than almost every other brand out there. It’s 33% more powerful and holds a larger charge than regular lithium batteries.

Even better is the fact these will work with most BLACK+DECKER products that use a 36 volt lithium battery.

Power Command Dial

On the handle is a power control knob that lets you dictate how much power the battery will use. For maximum trimming power, set the dial all the way up for 8500 RPMs. Or, for longer battery life, lower the dial and turn it down to 6500 RPMs.

Auto Feed Spool

The BLACK+DECKER auto feed spool means no more bumping. As the string wears out, the auto spool feeds new line out. This is time effective and cuts down on leaving divots in the grass from bumping.

Rotating Trimmer Head

Quickly go from regular trimming, to edging in seconds. The head rotates 180 degrees to make your yard look like it was edged by a professional.

The one downfall is the small cutting radius. It only cuts a 13” diameter which is much smaller than other weed eaters we looked at.

Overall, this is the weed eater you want if you prefer battery operated weed eaters. The ability to swap out batteries with other BLACK+DECKER products only adds to its charm. You can’t go wrong when you consider all you get for the low price you pay.

Electric/Corded Weed Eater Reviewed


  • Very Easy to Use
  • No Maintenance
  • No Emissions
  • Lightweight
  • Low Cost


  • Not as Powerful
  • Cord Can Get in the Way

The corded electric weed eater has been around for some time. It’s no stranger to lawn care and has built a reputation for being a cost effective tool to maintain your yard.

Low Cost – Ease of Use

The main draw to using these types of weed wackers their cost effectiveness and very easy maintenance load. To use one, just plug it in and start attacking your weed enemy . This ease-of-use does come at a price, however.

Limited Distance

Since they are powered by the AC grid, you need to have them plugged in at all times to use the tool. This can mean lugging around an extension cord (that can get heavy), or stopping periodically to plug it in to different outlets. You also run the risk of cutting the electric cord since it can get in the way at times.

While an electric corded weed eater does it have limitations; it can be the perfect fit for some. If you have a small yard with little grass to cut, this would be an ideal choice. You won’t be cutting down any large brush with one of these. But for small yards, they are perfect.

Gas Weed Eaters Reviewed

  • No Cords – Not Limited to a Small Area
  • Professional Grade Cutting


  • Stinky and Loud
  • Maintenance Required at Times
  • Carbon Footprint

A gas powered weed eater is common among professional lawn care crews. They are more powerful than electric and battery powered weed eaters. They are ideal if you have a larger yard since there is no issue with not having enough cord like an electric weed eater.

However, they take a little weed eater know how, to keep them maintained and running smooth.

Most gas powered weed eaters require a mixture of oil and gas. It’s rather simple to mix gas for a weed eater, but still an added step.

You will also need to perfrom some general weed eater maintenance. Changing spark plugs every so often; cleaning out the carb and so on. They aren’t extremely difficult to maintain. But some people would rather not have to deal with this.


Gas powered eaters will cost a bit more than most other weed eaters as well. You can find low priced weed eaters for smaller jobs, so this isn’t to say you can’t buy a “cheap” gas weed eater. Just keep this in mind when shopping for your next string trimmer.

Weed Eater Buying Guide

If you are struggling to determine which weed eater is right for you, our buying guide will help aide in your decision. Our goal here is to find out what your needs are, and fit you with the right weed eater.

What Are Your Weed Eating Needs?

The first step in choosing the right weed eater, is to determine what it will be used for.

  • How big is your yard?
  • Do you have thick weeds?
  • Are you handy?
  • Are you environmentally friendly?
  • Can you handle a powerful weed eater?

These, along with other questions are what you should be asking yourself before purchasing a weed eater. You don’t want to spend $300 on a top of the line weed eater; when all you need is a $90 battery powered one that will do the job just as well.

Yard Size

Larger yards require a weed eater that will last for the duration of the cut. A corded weed eater will be rendered useless on a bigger area. If you need a weed eater that will be able to reach across a distance; and last longer. A gas, or battery powered weed eater is a solid choice.


You also need to factor in cost. If you are on a budget, a gas powered weed eater may not be the best fit. They are generally the most expensive out of all types of weed eaters. You may instead look at electric or battery powered ones.

Thick Weeds

Trimming down brush, or other thick areas will need a more powerful trimmer. Battery and corded weed eaters lack the essential power to take down larger weeds. Gas will be the only way to go on tougher jobs.

Ease of Use

All weed eaters are relatively easy to use. But gas powered ones will require a little extra work. You will need to mix fuel, change spark plugs from time to time. And general repairs may need to be made over time.

If you aren’t very handy, or just want something simple with low maintenance, a battery powered, or corded weed eater will be what you want.

Angled Shafts vs. Straight Shafts

Some weed eaters will have a shaft that has a 90 degree bend at the trimming blade. Others will be straight. The ones with the bend will be easier to use and manage. The angle makes it hit exactly where you need it most of the time.

However, the bend in the shaft does have limitations. You won’t be able to get into hard to reach areas for one. It can be very difficult to get a good cut underneath bushes since the angle will stop the blade from going to deep. Trying to edge with an angled shaft is also very difficult.

A straight shaft weed trimmer will a little trickier to use, but if you can get the hang of it, you can do more. They will reach tough spots and can easily be flipped to get a nice edge around or garden.
