Battery timing can be an important factor for you if you are dealing with larger area as most of them can only run up to an hour so you would be required to recharge them after use. You should choose the product with best battery timing if you are required to use it more in a single session. Always choose trimmers which come with some warranty as they can cause some issues sometimes. Buying a product that provides technical support and warranty can save your money.

Your trimmer should be easy to use:

Always buy a trimmer which is easy to use and you are comfortable with it. A cordless trimmer can give you ease of mobility as compared to electric trimmers that come with a chord. Looking at the battery timing your trimmer should provide you enough flexibility and ease to finish your work around an hour or so.

The weight of trimmer:

For a cordless trimmer this is an important factor as you need to carry it around while working where fatigue factor comes into play after sometime and it can be hard to use it further.

You should go for a light weight trimmer which can solve your problem if you have any back issues. You should be aware of the weight you can carry easily and while buying a trimmer for your garden you should consider the weight of device.

3 Best Battery Powered Weed Eaters – Reviews

1) Black & Decker LST300 12-Inch Cordless Trimmer 20-volt

The Black & Decker LST300 12-Inch 20-volt Cordless Trimmer and Edger already has accumulated a lot of great views, drawing our attention to test what so many users like about this weed eater. Based on our tests, this weed eater is best for the casual gardener, or those that use this tool for light lawn maintenance and not in any professional or heavy impact applications.

The Black & Decker LST300 12-Inch 20-volt Cordless Trimmer and Edger is light-weight even with the battery on board, making it easy to use around the yard. Please note that those over 6 feet or taller, might find they have to bend over more a bit more with this weed eater due to the compact nature. The 20-volt battery does provide up to 33% more runtime than previous models but is still not robust enough to hold hours of use, and it will take a few hours to recharge. We found at best, it can provide about 30 minutes of continuous use. If needing this for thick turf and weeds we found this to not be a sufficient tool to use.

The plus of this weed eater is the affordable price tag and the size, which makes usage on small lawn maintenance projects an ideal for this weed eater.

Why then, should you purchase this weed eater? Well, it is very affordable and is absolutely appropriate for small lawn maintenance work.

2) WORX GT 2.0 WG160 Cordless Lithium Yard Trimmer/Edger and Mini Mower, 20-volt

The WORX GT 2.0 WG160 Cordless Lithium Yard Trimmer/Edger and Mini Lawn Mower, 20-volt with a price tag under $125, and boasting the ability to do three varied types of lawn maintenance made it an ideal weed eater to evaluate next. We took it out for a spin and here’s what we found.

The WORX GT 2.0 WG160 Cordless Lithium Yard Trimmer/Edger and Mini Lawn Mower, 20-volt wins in the lightweight category due to its weight making it easy to manipulate. There was no pressure or discomfort when using this weed eater, and had some pros but as a mower, we found this model sadly lacking. The wheel attachments are not sturdy nor sufficient to move easily over grassy lawns and absolutely needed to be used for optimum outcome as a weed eater that would be over the grass in a gliding motion.

Here’s a video showing the various functionality.

Best Electric Weed Wacker

When it came to judging this weed eater for power the WORX GT 2.0 WG160 performed well as an upkeep and light maintenance tool. Again, this is not the tool to be used for thick weeds or high thick turf.

A disadvantage to this product is its battery life, based on the reviews posted show users getting an average of 20 minutes usage only on this battery. Obviously, when doing a large lawn this can cause undue disruptions while you wait for a recharge. The best outcome by reviewers was noted when they have a back-up battery on hand to allow quick swapping of said battery in this model.

Overall, the WORX GT 2.0 WG160 Cordless Lithium weed eater/Edger makes a great addition to any gardening shed for the basic lawn needs.

3) Greenworks 21302 13-Inch 40V Cordless String Trimmer

Among the highlights of the GreenWorks 21302 Cordless weed eater is the capability of the pivoting head to smoothly change its position for a more even cut. Also, it is equipped with a security feature that stops the trimmer from starting accidentally. This weed eater is the most suitable to novice lawn maintenance users, due to the ease of setup and use.

The only disadvantage to selecting the GreenWorks 21302 Cordless weed eater is the expense of replacement batteries, as some users have reported having to replace their batteries after only 6 months.

Factors to Consider

Battery Life

How long do you plan on using your weed eater for at a time? This can make a big difference in the type of cordless weed eater you choose.

Nickel Cadmium batteries are generally cheaper, but will have shorter life. Additionally, as they get low, the performance drops. So while the manufacturer may say that it has a 60 minute battery life, it may only be good for 40 minutes. Of course, if you have a very small yard, that may be plenty of time.

Cordless trimmers with lithium ion batteries might cost a bit more, but they will also allow for much longer trimming time. You’ll spend less time recharging which ain’t nobody got time for. Plus, lithium ion batteries tend to perform more consistently.


Weight is a big factor that everyone should consider. Cadmium batteries tend to weigh more than lithium ion types, and different models have different weights. Usually to get a lighter string trimmer, you trade off one of two things: power or price. So choose wisely.

Shaft Type

Cordless weed eaters are no different than any other type in that they come with two shaft types: curved shafts and straight shafts.

Curved tend to be preferred by most, as they are a bit easier to get under bushes and around obstacles. They’re a bit more ergonomic. Straight shafts are a bit better if your cutting is always routine and straightforward, which is why often landscapers prefer straight shafts.

Either way, it’s personal preference.


Of course, you have to consider price. The reality here is for the most part, you get what you pay for. Cheaper battery powered weed eaters are going to be less durable, need more recharging, and be heavier…on average.

However, you also have to consider your use case. Do you live in a townhouse with 10 feet of edging to trim? By all means go with a cheaper model; it will last you a century at that rate. Do you have a larger yard that will take 30-40 minutes to trim? Probably worth investing in a more expensive model. Of course, you can always look at corded and gas-powered weed eaters as an alternative.
