Pros
- ✓ Brushless motor provides efficient power and longer runtime
- ✓ Tool-free depth adjustment makes setup quick and easy
- ✓ Lightweight design reduces fatigue during use
Cons
- ✗ 0Ah battery may require frequent recharging for larger yards
- ✗ No variable speed trigger for finer control
My Honest Opinion
This edger is a solid choice for homeowners seeking a reliable, cordless option. Its lightweight build and brushless motor make it easy to handle, though the battery life could be better for bigger lawns.
The Greenworks 60V edger excels in convenience with its tool-free depth adjustment and brushless motor, which delivers consistent power without the hassle of cords. The 8-inch blade cuts cleanly along sidewalks and driveways, and the lightweight frame makes it easy to maneuver around flower beds. However, the included 2.0Ah battery may not last through a full large-yard edging session, so a spare battery is recommended for bigger properties.
Overall, this edger offers great value for its price point, especially with the 4-year warranty backing it. The lack of a variable speed trigger is a minor drawback, but the tool-free depth adjustment and reliable performance make it a strong contender in the cordless edger market. It’s ideal for small to medium lawns where portability and ease of use are priorities.
WORX Cordless String Trimmer
The WORX WG163 is a versatile 2-in-1 cordless string trimmer and edger designed for small to medium lawns. It comes with two 20V batteries and a charger, making it convenient for quick yard touch-ups without the hassle of cords.
Pros
- ✓ Lightweight design at only 5.5 lbs, reducing fatigue during use
- ✓ Command Feed system allows for automatic line advancement with a button press
- ✓ Converts easily from trimmer to edger with a simple twist of the head
Cons
- ✗ Battery life may be limited for larger yards, requiring frequent swaps
- ✗ Cutting width of 12 inches is narrower than some competing models
My Honest Opinion
I find the WORX WG163 to be a reliable and user-friendly tool for maintaining a tidy lawn. Its lightweight build and easy conversion between modes make it a great choice for homeowners who prioritize convenience over heavy-duty performance.
The WORX Cordless String Trimmer & Lawn Edger impresses with its thoughtful design and ease of use. The Command Feed system is a standout feature, letting you advance the cutting line without stopping to bump the head, which saves time during trimming sessions. The 20V battery provides enough power for light to moderate grass and weeds, and having two batteries included means you can keep working while one charges. The 12-inch cutting path is adequate for edging along sidewalks and flower beds, though it may require more passes on larger lawns.
In practice, the WG163 handles well thanks to its balanced weight and adjustable handle. Switching from trimmer to edger is intuitive—just rotate the head 90 degrees—and the edging guide helps maintain a straight line. However, the batteries drain faster when tackling thick or wet grass, so you might need to plan your work accordingly. Overall, this is a solid entry-level cordless option that delivers on its promise of cord-free convenience for routine yard maintenance.

My Honest Opinion
I find this edger to be a solid choice for small to medium lawns where precision and ease of use matter most. The battery life is a trade-off for the lightweight build, but it handles routine edging well. Overall, it’s a reliable tool for maintaining neat edges without the hassle of cords.
The BLACK+DECKER 20V MAX Cordless Edger excels in user-friendly operation, thanks to its lightweight frame and adjustable height settings. The 7.5-inch double-edge blade cuts cleanly along sidewalks and driveways, and the tool starts instantly with a trigger switch. However, the included 1.5 Ah battery provides about 20-25 minutes of runtime, which may not cover larger yards in one go. Charging takes around 1-2 hours, so planning is needed for bigger jobs.
For routine maintenance, this edger performs admirably on grass and soft soil, but struggles with thick weeds or compacted edges. The lack of a telescoping handle limits customization for taller users, though the four height positions help. Overall, it’s a great entry-level cordless option for those prioritizing convenience and lightweight handling over heavy-duty power.

- ✓ Adjustable depth control allows for customized edging and trenching
- ✓ Lightweight and easy to maneuver, reducing user fatigue
Cons

My Honest Opinion
I find this WORX edger to be a reliable and efficient tool for maintaining crisp lawn edges. Its corded power ensures consistent performance, though the cord can be a minor inconvenience. Overall, it's a great value for the price.
Buyer’s Guide: 3 Key Factors to Consider
Power Source
Battery voltage and amp-hours determine runtime and cutting strength; higher voltage (like 60V) handles thicker grass, while 20V models are lighter for smaller yards.
Blade & Cutting Width
Wider blades (8-12 inches) cover more ground faster, while double-edge or adjustable blades offer better precision for clean edges along sidewalks and flower beds.
Adjustability & Weight
Tool-free depth settings and adjustable handles reduce fatigue, and lighter models (under 10 lbs) are easier to maneuver for longer edging sessions.
Frequently Asked Questions
What’s the difference between a cordless edger and a string trimmer?
An edger uses a rigid blade to cut a clean vertical line along hard surfaces, while a string trimmer uses a flexible line for general grass trimming and shaping.
How long does a battery typically last on these edgers?
It depends on the battery size and grass thickness. A 2.0Ah battery usually runs 15-25 minutes, while a 4.0Ah battery can last 30-45 minutes on a single charge.
Can I use these edgers for trenching or digging?
Some models like the WORX WG898 have a trencher mode for shallow digging, but most cordless edgers are designed for surface-level grass cutting only.
Do I need to buy extra batteries separately?
Most kits include at least one battery and charger, but if you have a large yard, buying a second battery (like the WORX 20V 4.0Ah) can help avoid downtime.
Are cordless edgers powerful enough for thick, overgrown grass?
Yes, especially brushless motor models (like the Greenworks 60V) which provide more torque and efficiency for tackling dense or tall grass without bogging down.
