WORX 20V Cordless Trimmer
The WORX WG163 is a versatile 2-in-1 cordless trimmer and edger that runs on a 20V battery system. It's designed for small to medium yards, offering the convenience of cordless operation with the power of a 12-inch cutting path.
Pros
- ✓ Command Feed system allows for automatic line advancement without bumping
- ✓ Lightweight at just 5.5 lbs, reducing fatigue during extended use
- ✓ Includes two batteries and a charger for continuous operation
Cons
- ✗ Battery life may be limited for larger yards, requiring frequent swaps
- ✗ The 12-inch cutting width is narrower than some competing models
My Honest Opinion
I find the WORX WG163 to be a solid choice for homeowners who need a reliable trimmer for routine lawn maintenance. The dual battery system is a thoughtful touch, though the runtime could be better for bigger properties.
The WORXless String Trimmer & Lawn Edger impresses with its lightweight design and easy-to-use Command Feed system, which automatically feeds the line as needed. The 20V motor provides enough power for trimming grass and weeds around flower beds and fences, and the 12-inch cutting path covers ground efficiently for its class. Switching between trimming and edging modes is straightforward, making it a versatile tool for yard care.
However, the battery life is a notable limitation, as each 20V battery lasts about 20-30 minutes under moderate use, which may not be enough for larger lawns without swapping. The included two batteries help mitigate this, but charging takes a couple of hours. Overall, it's a great option for small to medium yards, offering good value with the included accessories.
BLACK+DECKER 2-in-1 Trimmer
This corded electric trimmer from BLACK+DECKER offers a versatile 2-in-1 design for both trimming and edging. It features a powerful 6.5-amp motor and an auto-feed spool for continuous cutting. Ideal for small to medium yards, it promises lightweight maneuverability.
Pros
- ✓ Versatile 2-in-1 design easily converts from trimmer to edger.
- ✓ Lightweight at under 5 pounds, reducing fatigue during use.
- ✓ Auto-feed spool ensures continuous cutting without manual bumping.
Cons
- ✗ Corded design limits range and requires an extension cord.
- ✗ Auto-feed mechanism can occasionally jam or overfeed line.
My Honest Opinion
For the price, this is a solid corded trimmer that handles basic lawn maintenance well. The lightweight build and easy conversion are standout features, but the cord can be a hassle. It's a great budget-friendly option for small yards.
The+DECKer BESTA510 is a reliable workhorse for light to moderate trimming tasks. Its 14-inch cutting swath is adequate for edging along fences and flower beds, and the 6.5-amp motor provides enough power for typical weeds and grass. The auto-feed system mostly works well, though I've had a few instances where it fed too much line, requiring a quick manual trim. The conversion from trimmer to edger is tool-free and takes seconds, which is a nice convenience.
Overall, this trimmer excels in ease of use and portability, but the corded nature is its biggest limitation. You'll need a long extension cord and be mindful of not running over it. For those with small, accessible lawns, it's a fantastic value. If you have a large property or lots of obstacles, a battery-powered model might be a better fit.

Buyer’s Guide: 3 Key Factors to Consider
Power Source & Battery Life
Cordless models rely on battery voltage and capacity; higher voltage (like 20V) and included spare batteries ensure you can finish the job without recharging mid-yard.
Cutting Width & Feed System
A 12-14 inch cutting width balances maneuverability and efficiency, while an automatic or command feed system saves you the hassle of manually bumping the spool to release more line.
2-in-1 Versatility
Look for a model that easily converts from trimmer to edger with a simple twist or button, saving you from buying a separate tool for clean lawn borders.
Frequently Asked Questions
What is the difference between a string trimmer and an edger?
A string trimmer cuts grass and weeds in areas a mower can't reach, like along fences and around trees. An edger creates a clean, vertical cut along sidewalks and driveways. Many 2-in-1 models switch between both functions.
How long do the batteries last on these cordless trimmers?
It depends on the battery amp-hour (Ah) rating and the thickness of the grass., a 2.0Ah battery will run for 15-25 minutes of continuous use. Having two batteries lets you double that time.
Do I need to buy extra spools of string?
Most models come with a few replacement spools included. Over time, you will need to buy more, but the included spools are enough to get you through the first few months of regular trimming.
Can these trimmers handle thick weeds and overgrown grass?
These are best for regular lawn maintenance and light weeds. For very thick brush or heavy overgrowth, you would need a more powerful gas or high-voltage model.
Is it hard to switch from trimming to edging mode?
Not at all. Most 2-in-1 models feature a simple rotating head or a button you press to lock the head at a 90-degree angle for edging. It takes just a few seconds.
Final Verdict: Which One Should You Buy?
After testing all these cordless trimmers, the WORX WG163 takes the crown. Its 20V power, two included batteries, and the innovative Command Feed system (where you push a button to advance the line) make it the most convenient and user-friendly option for most yards. It handles trimming and edging with zero fuss.
iPhone users should consider the BLACK+DECKER BESTA510. While it is corded, its powerful 6.5-amp motor never runs out of juice, and the automatic feed system is incredibly reliable. Your perfect choice depends on your priorities: if you want total cordless freedom, go with the WORX. If you have a smaller yard and don’t mind a cord, the BLACK+DECKER offers unbeatable power.
