2. Black+Decker Max Cordless Sweeper LCC340C

 

The motor on this trimmer and edger comes with Power Drive high torque transmission that will deliver a cleaner, faster cut every time you use. On the other hand, the LSW40 40-volt Max Sweeper can blow with a wind speed of up to 130 mph, enough to clear leaves and debris from hard surfaces such as concrete and pavement.

Both products are equipped with low-noise technologies to make them quieter and easier to use all day long without worrying about waking up the neighbors or your baby. Moreover, both units provide a state-of-charge indicator that shows exactly how much battery you have left before you’ll have to recharge. This way, you can plan your gardening chores and never worry about running out of power.

3. GreenWorks G-MAX Cordless Trimmer STBA40B210

 

GreenWorks boasts an entire line of equipment based on interchangeable batteries, which is a more sustainable and lightweight option than products that run on gas or electrical power.

The set contains a blower, a string trimmer, as well as a battery and a charger included so that you can start on your gardening chores as soon as possible.

The innovative axial fan design can blow wind with up to 110 mph, enough to handle tough cleaning jobs from various types of surfaces.

Cons

Although the manufacturer states that you’ll get up to 45 minutes of run time on a single charge, you don’t need to get your hopes up too high. Even after just a few uses, the battery won’t seem to last more than 20 minutes, making it difficult to finish trimming a bigger lawn.

The blower only uses a total wind speed of 110 MPH, lower than other models within the same price range.

The item features a lightweight and ergonomic design, making it easy to handle it using only one hand, without suffering from fatigue even when operating it for a long time.

Equipped with Power Drive Transmission, this trimmer will deliver increased torque. You also get to choose between two different speeds, depending on the necessities of your grass and weeds.

What we also liked about the new LSTE525 is the easy feed function that allows you to advance the line with a single push of a button, without requiring any bumping. And, if you’re willing to cut the grass on the edges of your lawn, you can convert the device from a trimmer to a wheeled edger in just a matter of seconds.

Cons

After taking the battery out of the box for the first time, you’ll have to fully recharge it for about 3 hours before being able to use the weed eater. And, even though the manufacturer states you’ll get up to 45 minutes of continuous use with a single charge, don’t expect to perform your tasks for more than 20 minutes at a time.

Prepare to benefit from one of the most powerful batteries on the market, a 56V one that will deliver more cutting power.

It is delivered with a rapid reload trimmer head that rewinds your line faster and easier so you can finish your cutting grass operation as fast as possible.

The handle is ergonomic and won’t cause hand fatigue even when you operate the device for a longer time.

 

Cons

All EGO parts should be genuine to ensure quality, performance, and compatibility, and this includes a powerhead, a battery, and a charging station.

The rubberized wheels ensure cleaner cuts and straighter lines.

 

Cons

Buy from Amazon.com for ($94.99)

 

 

 

7. Worx WG191 Cordless String Trimmer & Edger

 

Boasting a powerful 56V battery, this product promises to deliver gas-like performance with zero emissions and up to one hour of full, uninterrupted use in just one charge.

We also liked the rotating rear handle that is ergonomic and provides maximum comfort while edging.

 

Cons

As with many other products that run on batteries, even though this means zero gas emissions, you will experience less running time after a while. The battery takes about 3 hours to fully charge but won’t provide more than 30-40 minutes of continuous use in time.

Another weakness of this particular weed eater is the fact that it holds little string that constantly jams.

Our Comprehensive Buying Guide

 

When picking a cordless electric weed eater you’ll need to pay attention to several factors to make sure the product you are buying is the right one for your gardening requirements. Here is what to look for.

 

 

Running power

There are three main types of weed eaters available on the market today, so pick the type that is suitable for you.

Gas-operated units are amongst the most powerful and will use a combination of ethanol-free gas and oil to operate. The downside of these products is that you’ll have to make sure there is enough gas in the tank to finish the operation, as otherwise, your engine will die in the middle of the job. And, since they use a full tank of gas, they are heavier and less convenient to carry around.

Battery-powered weed eaters are an eco-friendly option and one of the most popular today. You won’t have to look for a long cord to fuel your weed eater and, since technologies evolved in the field, you can now run such a device for up to 60 minutes. Most batteries are rechargeable too, and you won’t have to spend more than 45 minutes recharging them. Thus, you can finish trimming and eliminating weeds from your garden or lawn faster.

Electrical weed eaters are lightweight and portable but you will still need a cord to keep them running. This makes for less convenience as you’ll always have to look for a power outlet nearby. They are good for a small yard and are powerful enough to get the job done.

 

Weight

Weight is one of the most important factors you need to consider when looking for these items. Battery-operated cordless weed eaters are lightweight by comparison to the ones that run on gas because they don’t require the use of a tank. They can be easily operated with just one hand and won’t cause fatigue or wrist pain even when you use them for an hour.

 

Battery life

When going through numerous online cordless weed eater reviews, another important criterion to focus on is the battery life of your product. Opt for products operated by high-power batteries with longer lives and you won’t have to replace them or recharge them too often.

Generally speaking, a cordless weed eater can run for up to 60 minutes on a single battery charge but this will change once you start using your device more often. In time, the battery won’t seem to last more than 10 minutes, and this is when you’ll have to replace it.

And, if you don’t want to run out of battery with plenty of work in the garden ahead of you, we always recommend having a spare battery already charged and ready to use. It won’t take more than a couple of minutes to change and you’ll be able to continue your gardening chores.

 

The trimmer’s design

In our opinion, the best cordless electric weed eater is not only lightweight but also features an ergonomic design. The product should be easy to operate with just one hand and should be compact enough to be easily carried and stored.

You also need to check the way the weight is distributed to make sure the weed eater doesn’t feel too heavy even when it shouldn’t. Look for units with straight shafts as they can easily transfer power from the motor to the lines cutting the grass.

 

 

Frequently Asked Questions

 

Q: How do you use a cordless weed eater?

These products are simple to use and most of them come with step-by-step easy-to-follow instructions on how to build them and operate them. Once everything is in place, all you’ll have to do is turn the engine on and start cutting grass and weeds on your lawn.

However, there are various cutting techniques that you will learn to master in time, depending on your needs. For instance, when it comes to treating the edges of the lawn, you can choose between tapering or edging.

In tapering, you have to hold the tool so that the string strikes the grass at a slight angle. Edging may sound more complicated but will help you achieve a clean and symmetric cut all over your backyard, even between the grass and the driveway. For that, you’ll have to start with your trimmer in a vertical position. Walk the tool into the cut path so it can eject grass where you just cut.

 

 

Q: Based on what criteria should you choose a cordless weed eater?

As we previously mentioned in our comprehensive buying guide, there are various criteria you should take into account. However, going for a cheap cordless weed eater won’t always equal quality, so it would be best to rule out the price from your list of things you should look for.

The first and most important is the power of the motor. A powerful motor will help you finish the job faster and better and is less likely to get clogged with dirt and debris.

A lightweight and compact design is another important feature to consider given that you will be operating the machine with your hands. Such a device shouldn’t weigh more than 10 pounds if you want to cut or trim grass for a full hour in a row.

Some products on the market are sold together with a leaf blower which will help you finish all your gardening and cleaning chores faster and easier.

 

Q: How long does the battery last?

As we have mentioned above, battery power is an important feature to take into account when opting for a weed eater. As technologies evolved, batteries are now more powerful and can last up to 60 minutes of continuous use with one single charge. However, it depends on the battery’s power, producer, and how often you use your device.

Unfortunately, batteries aren’t meant to last forever, and you will soon notice that they drain faster. Although certain techniques can prolong your battery life, you will have to replace it sooner or later.

If you don’t want to run out of power while you’re cutting the grass, we suggest you have a battery replacement at hand. All products are usually delivered with spare batteries and a recharging station so that all your gardening chores are done without effort and as fast as possible.
