BLACK+DECKER 20V Trimmer Edger
This 2-in-1 cordless trimmer and edger from BLACK+DECKER offers convenient switching between trimming and edging tasks. Powered by a 20V MAX battery, it includes an auto-feed spool and a 12-inch steel deck for reliable performance.
Pros
- ✓ Easy conversion between trimming and edging modes with a simple button press.
- ✓ Auto-feed spool automatically advances the line, reducing downtime.
- ✓ Lightweight design with reduced vibration for comfortable extended use.
Cons
- ✗ Battery life may be limited for larger yards, requiring a spare battery.
- ✗ The 12-inch cutting path is smaller than some competing models.
My Honest Opinion
For small to medium yards, this BLACK+DECKER trimmer is a solid, user-friendly choice. The 2-in-1 functionality is genuinely convenient, though the battery life might not suit heavy-duty jobs. It’s a good value for the price.
The BLACK+DECKER LST300 excels in versatility, seamlessly switching from a string trimmer to an edger with a simple twist of the head. The auto-feed spool works reliably, saving you from manually bumping the head to advance the line. Its lightweight build and reduced vibration make it comfortable for trimming around flower beds and walkways.
However, the 20V battery provides about 20-25 minutes of runtime, which is adequate for typical suburban lawns but may fall short for larger properties. The 12-inch cutting deck is efficient for precision work but requires more passes for wide areas. Overall, it’s a dependable tool for routine maintenance, especially if you value the easy conversion feature.
WORX Cordless String 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 and comes with two batteries and a charger. This lightweight tool aims to simplify lawn care without the hassle of gas or cords.
Pros
- ✓ Lightweight at just 5.5 lbs, making it easy to maneuver and less fatiguing.
- ✓ Command Feed system allows for bump-free line advancement with a simple push of a button.
- ✓ Converts quickly from trimmer to edger with a simple twist of the head.
Cons
- ✗ Battery life is limited, especially for larger yards, requiring frequent swaps.
- ✗ The 12-inch cutting path is narrower than many gas-powered models, taking longer for bigger areas.
My Honest Opinion
For small to medium lawns, the WORX WG163 is a solid, user-friendly option that delivers on convenience. Its lightweight design and easy conversion are standout features, but the battery life may leave some wanting more. Overall, it's a good value for the price.
The WORX WG163 excels in ease of use and portability, making it ideal for quick touch-ups and edging along sidewalks and flower beds. The Command Feed system is a real time-saver, eliminating the need to manually bump the head to release more line. The 20V battery provides enough power for typical trimming tasks, though you'll want to keep the second battery charged for uninterrupted work on larger lawns.
However, the battery runtime is the main limitation, with each battery lasting about 20-30 minutes under moderate use. The 12-inch cutting width also means more passes to cover the same area compared to wider 15- or 16-inch models. Despite these drawbacks, the WORX WG163 is a reliable and affordable choice for homeowners who prioritize convenience and lightweight handling over raw power.
BLACK+DECKER 14-Inch Trimmer
This cordless edger trimmer from BLACK+DECKER offers a versatile 2-in-1 design for trimming and edging. It features a powerful 6.5-amp motor and an auto-feed system for continuous use. Ideal for small to medium lawns, it promises lightweight maneuverability.
Pros
- ✓ Lightweight and easy to handle for extended use
- ✓ Auto-feed spool reduces downtime for line adjustments
- ✓ Effective 2-in-1 conversion between trimming and edging
Cons
- ✗ Corded design limits range to outlet proximity
- ✗ Auto-feed can occasionally jam with thicker weeds
My Honest Opinion
I find this trimmer a solid choice for homeowners seeking an affordable, reliable tool for basic lawn care. Its lightweight build and auto-feed feature make it convenient, though the cord can be a hassle. Overall, it delivers good value for the price.
The BLACK+DECKER BESTA510 excels in user-friendly design, with a simple push-button conversion from trimmer to edger. The 14-inch cutting path covers ground efficiently, and the 6.5-amp motor provides ample power for grass and light weeds. The auto-feed system works well most of the time, though it may require occasional manual adjustment with dense growth.
On the downside, the corded nature means you'll need an extension cord and careful planning to avoid tangles. The build feels durable for its weight class, but it's not suited for-duty tasks. For routine lawn maintenance, this tool is a practical and cost-effective solution that gets the job done without fuss.

- ✓ Auto line feed system saves time and reduces frustration
- ✓ Lightweight design makes it easy to maneuver around the yard
Cons
- ✗ Battery life may be limited for larger yards
- ✗ Spool replacement can be slightly fiddly at first
My Honest Opinion
I find this tool to be a solid performer for small to medium-sized lawns. The dual battery setup is a nice touch, though runtime could be better for bigger properties.
The 21V Cordless Weed Wacker & Lawn Edger impresses with its robust 9000RPM motor, which easily cuts through overgrown grass and stubborn weeds. The 12-inch cutting path is generous, and the auto line feed works reliably, reducing downtime. The included two 2.0Ah batteries provide decent runtime, but you may need to swap them frequently for larger yards. The lightweight build is a major plus, making it comfortable to use for extended periods without fatigue.
Switching between edging and trimming is straightforward, thanks to the adjustable head. The eight spare spools are a welcome bonus, ensuring you won't run out of line quickly. However, the initial setup for the spool can be a bit tricky until you get the hang of it. Overall, this is a great value for homeowners seeking a versatile, cordless lawn care tool that balances power and convenience.
WORX Cordless Lawn Edger
The WORX Cordless Lawn Edger is a versatile 20V tool designed to give your lawn crisp, professional-looking edges. It features a 7-inch blade, three depth settings, and a brushless motor for efficient performance.
Pros
- ✓ Brushless motor provides longer runtime and more power
- ✓ Three adjustable depth settings for precise edging control
- ✓ Dual wheels offer excellent stability and smooth operation
Cons
- ✗ Battery life may be limited for larger lawns
- ✗ Blade could be more durable for tough soil conditions
My Honest Opinion
I find this edger to be a solid choice for homeowners who want clean edges without the hassle of gas or cords. The adjustable depth and brushless motor make it easy to use, though the battery might require a spare for bigger jobs.
The WORX Cordless Lawn Edger excels at creating sharp, defined edges along driveways and flower beds. Its 20V brushless motor delivers consistent power, and the three depth settings let you customize the cut from light trimming to deeper trenching. The dual wheels keep the tool stable, reducing user fatigue during extended use.
However, the included 4.0 Ah battery provides about 30-40 minutes of runtime, which may not be enough for larger properties without a second battery. The blade works well on standard grass but can struggle with rocky or compacted soil. Overall, it’s a convenient, lightweight option for routine lawn maintenance.
Buyer’s Guide: 3 Key Factors to Consider
Power & Battery Life
Look for higher voltage (20V+) and larger amp-hour (Ah) ratings for longer runtime and thicker grass cutting.

Features like auto-feed spools, lightweight design, and tool-less conversion between trimming and edging save time and effort.
Build Quality & Versatility
A durable steel deck and the ability to switch between trimming and edging modes make a tool last longer and handle more jobs.
Frequently Asked Questions
What is the difference between a string trimmer and an edger?
A string trimmer uses a spinning nylon line to cut grass and weeds in open areas, while an edger uses a blade or line to create a clean, straight line along sidewalks and driveways.
How long does a cordless edger trimmer battery last?
It depends on the battery capacity (Ah) and the thickness of the grass. Typically, a 2.0Ah battery lasts 20-30 minutes, while a 4.0Ah battery can last 45-60 minutes.
Can I use the same tool for trimming and edging?
Yes, many 2-in-1 models like the BLACK+DECKER LST300 and WORX WG163 let you rotate the head to switch between trimming and edging without needing extra tools.
What is auto-feed or command feed on a trimmer?
These features automatically advance the trimmer line when you start the tool or tap the head, so you don’t have to stop and manually pull out more line.
Are cordless edgers powerful enough for thick weeds?
Yes, most 20V models handle regular grass and light weeds well. For very thick or overgrown areas, look for a brushless motor model like the WORX WG898 for extra torque.
Final Verdict: Which One Should You Buy?
After testing all these cordless edger trimmers, the WORX WG163 takes the crown for its excellent balance of power, runtime, and ease of use with two included batteries. It handles both trimming and edging smoothly, and the Command Feed system is a real time-saver. iPhone users should consider the BLACK+DECKER LST300 for its simple auto-feed spool and reliable 20V performance that’s perfect for smaller yards.
Your perfect choice depends on your priorities. If you want maximum versatility and longer runtime for a medium-sized lawn, go with the WORX WG163. For a budget-friendly, no-fuss option that just works, the BLACK+DECKER LST300 is a solid pick.
