8 Best Cordless String Trimmers 2020

8 BEST Cordless String Trimmers 2020

If you have a smallish yard with those spots you can't easily maintain with a lawnmower, and you like to keep your garden tidy and polished, consider trying an electric string trimmer.

Compared to traditional gas-powered string trimmers, electric models are easier to maintain because you don't need to worry about the mess of mixing fuel or storing gasoline. Having an electrical outlet will fix the powering issue.

One the other hand, even if corded electric string trimmers are a better option than gas-powered tools, this one must always be plugged into an outlet to operate, which limits your freedom of movement.

With a cordless electric string trimmer, you will be able to roam wherever you like on your property, making it so much easier and comfortable for you. And the most suitable option for your home yard.

In this light, we created the following list of the best cordless trimmers in the market, listed according to the need of each one reading this.

So before going into it, you need to understand your needs right.

Choosing The Right String Trimmer for Your Needs

Here are some basic guidelines for which model is right for you and what other features you need. Here are some points to take into consideration.

How big is your yard?

If your yard is small, a standard battery will do the work for you. So spending too much money on a trimmer with a greater battery capacity while you don't even need it would be a waste of money.

And vice versa, having a large yard requires more trimming time, which leads you to get a battery capable of completing the work for you efficiently.

Are there obstacles in your yard?

Look at where you will be trimming around, are there any obstacles for your trimming, or would you be working around basic planting beds and trees? That would help you know the features you'll need. A pivotable head for the hard-to-reach spots, a space guard so you won't damage your plants and flowers, …

Other features to consider:

  • Weight: keep in mind that you will carry the tool in your hand for a long time, so consider weight and good balance when choosing your trimmer.
  • Quick charging: Some models need hours for a fully charged battery. In case you're using a single battery repeatedly for a large yard, it would be better for you to get a fast charger so you'll save plenty of time.
  • Connection capability: Some models feature a universal connector that lets your trimmer work with attachments from other brands, without voiding the warranty.
  • Noise: Even though electric weed eaters are considerably quiet, it's best to use ear protection when running string trimmers. The manufacturer's instructions specify the type of ear protection you need.

1- WORX WG163 GT3 (Most Popular on Amazon)

WORX WG163 GT3 - toolspros

The WORX's cordless weed eater model WG163 GT3, is the most purchased string trimmer on Amazon yet.

The tool comes with a pack of two 20-Volt batteries easily replaceable, providing a long time of use. The cutting diameter is 12 inches across, with a no-load speed of 7600 rpm that will cut through weeds and grass effortlessly, plus an option of a 90° pivotable head helping you access areas like those under your swing sets.

It also includes the ability to convert from a trimmer to an edger in a few seconds without the need for any additional tool for the conversion. All you have to do is use an easy pull to turn the trimmer head and turn to lock it in place. You'll end up then with a wheeled edger letting you trim along your sidewalks.

Besides what's mentioned, the WG163 is incredibly lightweight with 5.3 pounds only, making it a very comfortable tool to use, and the lightest model among other Worx's cordless trimmers.

All these functionalities and features come at a very affordable price compared to many other string trimmers in the market—no wonder for it to be the highest purchased weed trimmer.

  • An extra battery offered
  • Light-weighted
  • Pivotable head (90°)
  • Affordable
  • Warranty of 3 years

Cons:

  • Long charging time
  • Short shaft
  • Not meant for tough vegetation trimming

2- BLACK+DECKER LSTE523 (Several Features With Low Cost)

BLACK+DECKER LSTE523 - toolspros

This BLACK+DECKER weed eater has numerous functionalities at a very affordable price.

One of the main advantages is the two-speed setting, which is different from basic weed eaters we tend to see.

The speed selection is made using a switch between a 5200 Rpm speed for extended runtime, Which is suitable when cutting a wide area of thin grass growth because it will keep your battery charged longer.

The second switch offers a 7200 Rpm speed that will provide more power instead, Which is ideal when dealing with tough weeds.

It also uses the Power Drive Transmission system, which increases the torque as you approach heavier grass or weeds areas to give you more power to cut through them.

And the EASYFEED system allows you to advance your line with the push of a button - no bumping required.

The string trimmer comes with a flip-to-edge collar, which means you can switch between trimming and edging without worrying about adjusting the shaft length as you might usually have to do before.

A battery of 1.5 Ah is included, which is part of the manufacturer's 20V lithium battery system, it implies you can use it in any tool from the Black & Decker family as long as it has the same voltage.

The trimmer with the battery attached weighs 6.3 pounds, which is not heavy and overall comfortable to use.

Pros:

  • 2 Speed settings
  • High torque PowerDrive transmission

Firstly, the LST300 comes with a high speed of 6200 rpm, ready to go through all the thick weeds of your yard. Also equipped with a 2.0 amp-hour 20-Volt battery, that can be released and slides in quickly while offering a decent working time (an average of 20-30 minutes). However, to charge it, you need to wait a few hours. Therefore, in case your yard is large, a spare battery is necessary.

Besides, the string trimmer has a pivoting handle and an adjustable length, as well as the ability to turn into an edger in a few seconds, only by: unlocking the shaft, turning it on, and locking it again.

No wheel is contained to keep a distance from the ground while edging, yet the small metal guard will help you with that.

The automatic Feed Spool in this trimmer will ensure continuous work without bumping, with a line diameter of 0.065 inches.

The LST300 is a perfect trimmer for a small garden. It is lightweight, cordless, and quiet, so you'll have complete freedom of movements during the work. And yet at a very fair price.

  • Solid battery run time
  • Lightweight and very easy to use
  • Warranty of 3 years
