Portable Battery Lawn Edgers That Keep Your Lines Sharp
The Worx 20V Cordless String Trimmer and Edger stands out for its lightweight pivot design that turns from trimmer to edger with a simple twist. It suits small to medium yards where maneuverability matters most. Its main advantage is the tool-free conversion and adjustable head for precise edging. The main limitation is that it lacks the power for heavy, overgrown edges.
A clean edge along your driveway or flower bed instantly upgrades your lawn’s look. Portable battery edgers offer freedom from cords and gas, but picking one requires attention to weight, battery life, and cutting power.
In this roundup, we compared seven cordless edgers that vary in design and capability. Some are dedicated edgers, while others convert from trimmers. We focused on models that are genuinely portable and easy for most homeowners to use.

Good to know
What is the difference between a string edger and a blade edger?
A string edger uses a nylon line that spins to cut grass. It is flexible and good for curved edges. A blade edger uses a rigid metal blade to cut a clean trench, ideal for straight lines along sidewalks and driveways.
Can I use a battery edger for trimming too?
Some models like the Worx are 2-in-1 and convert from edger to trimmer. Dedicated edgers are not designed for trimming. If you need both, consider a convertible model.
How long does a battery edger run on one charge?
Run times vary from 20 to 60 minutes depending on battery voltage and amp-hour rating. Heavier grass and deeper cuts reduce runtime. EGO’s 56V model runs longest, while budget models often last 25 minutes.
Are battery edgers as powerful as gas edgers?
Modern battery edgers, especially 56V models, offer comparable power for residential use. They are quieter and require less maintenance. Gas edgers still lead in raw power for commercial work.
Do I need a separate battery and charger?
Many models come with a battery and charger. Some, like Ryobi, require you to use existing One+ batteries. Check the product description to see if the battery is included.
How deep can a battery edger cut?
Most edgers can cut up to 1 to 2 inches deep. You can adjust the depth on many models to suit your lawn. Blade edgers tend to cut deeper than string edgers.
Can I edge wet grass?
It is best to edge when the grass is dry. Wet grass can clog the blade or string, making the cut uneven. It also puts extra strain on the motor.
What safety gear should I wear when edging?
Wear safety glasses to protect your eyes from debris. Hearing protection is not necessary for battery models but can be comfortable. Long pants and closed-toe shoes are also recommended.
Our pick
For most homeowners, the Worx 20V Cordless String Trimmer and Edger is the best choice because it combines portability with versatility. If you have a large yard and need serious power, the EGO Power+ 56V Cordless Edger is worth the extra cost. For those on a budget, the Sun Joe offers reliable performance without breaking the bank.
