Best String Trimmers: Our Top Three Contenders

A string trimmer, also called a weed whacker in some areas, is usually a cordless power tool that runs on rechargeable batteries. These fast and reliable machines not only help keep lawns and gardens in perfect condition but can also be used for edging.

Here, we review the best ones from Worx, VonHaus, and Ryobi.

The Worx WG154 Cordless Grass Trimmer/Edger

This remarkable machine from Worx can easily be converted from a trimmer to an edger with just one touch, allowing you to move between functions effortlessly. It runs on a rechargeable 20V lithium-ion battery that only takes five hours to charge fully. You don’t have to worry about its charger, too, as it already comes with the package.

Depending on your needs and preferences, you can choose between two cutting width options— 10-inch or 12-inch. It is manufactured using lightweight yet materials and only weighs a little over six pounds. This means that you can edge and trim your entire lawn with minimal muscle straining.

With your convenience in mind, this trimmer/edger is equipped with a rotating head. An ergonomic front hand is also added to ensure a comfortable grip yet secured control. It also features a folding spacer guard, which allows you to use it to trim your garden while keeping the flowers protected.

If you are looking for an edger/trimmer that can be used out of the box, then this is the product for you. It powers up with just a push of a button, so there is no learning curve. Though it may require some assembly, it is nothing extraordinarily time-consuming.


  • Long-lasting battery
  • Dual purpose function
  • Easy to handle
  • Minimalist design
  • Durable
  • Can work on a medium-sized lawn on one charge


  • The spools are not high-quality
  • May need recharging if used on a large lawn

The VonHaus 40V Max Cordless String Trimmer/Edger

If what you are after is a powerful machine that is capable of trimming grass and edging lawns, then this string trimmer from VonHaus is the answer. It is a 40V cordless string trimmer with a 0.065-inch auto-feed line cutting system that offers a 9.8-inch cutting path.

This machine is remarkably awesome for edging and does so in a sophisticated way, leaving you with properly edged garden beds, walkways, and driveways. Its adjustable trimmer head rotation and edge guide make it the perfect power tool for this purpose.

If you are worried about straining your arms, you don’t have to with this machine as it weighs no more than 10 pounds. It also comes equipped with an auxiliary rubber handle that ensures a soft yet firm grip. This feature makes it possible to move it across your lawn without exerting too much force.

This product comes with a 2.0A lithium-ion battery and charger. An hour and 15 minutes of charge time provides you with a fully charged battery that is capable of getting the job done. The great thing about this machine is that it is also compatible with the batteries from other VonHaus gardening power tools.

For your safety, also included in the package are accessories like an edge guard and safety guard.


  • Powerful performance with speed
  • Battery charges quickly
  • Sophisticated design
  • Lightweight and easy to operate
  • Great for edging curves and around trunks


  • Cannot add another battery
  • May feel bulky after some time using it

The Ryobi P2052 One+ Cordless String Trimmer/Edger

The Ryobi P2052 One+ String Trimmer/Edger is arguably one of the lightest trimmer/edger you can find on the market today. Weighing only five pounds, not only does it feel lightweight but also not bulky like most trimmers. For this reason, it can be used to trim an entire lawn without fear of straining the arms.

In addition, and like the other two products we have reviewed so far, this trimmer/edger is also designed with a rotating shaft that allows for quick conversion from trimmer to edger. It works great when used to trim grass and edge around flower beds, trunks, and fences.

One major problem, however, is that the battery and charger are not included in the package. It is the user’s discretion as to which battery to use. For your reference, though, a small lithium-ion battery can give your about 15 minutes of operation, while a bigger one could deliver up to 30 minutes of runtime.

Save for the battery, it comes ready to be used out of the box. Even if you have never had a power lawn edger or trimmer before, you can master the ins and outs of this one quickly and easily. As such, it makes for a perfect trimmer/edger for beginners.


  • Extremely lightweight
  • Works great for trimming as well as edging, especially around difficult to reach areas
  • Simple design


  • Battery and charger not included

The Final Words

The three best string trimmers above all have a few things in common. First, they can be used as either a trimmer or edger. In addition, all three of them are also very easy to operate, run on powerful batteries, and are cordless, allowing you to move around the lawn to trim the grass or edge it with ease.

The Worx String Trimmer is a simple but robust trimmer that gives you two cutting widths. The VonHaus one is even most powerful and charges pretty fast. However, due to the auto-feed and extra accessories, it is a little expensive than the other two. The Ryobi trimmer is the lightest of the three and, therefore, highly maneuverable and portable.

All three offer great value for money and are suitable for normal use in the backyard, front yard, and lawns. You can get clean looking garden beds, trees, and grass that can elevate the look of your entire home.
