BLACK+DECKER 20V Trimmer
The BLACK+DECKER LST300 is a versatile 2-in-1 cordless string trimmer and edger designed for small to medium yards. It includes a 20V MAX battery and charger, making it ready to use out of the box. This model features an auto spool feed and a 12-inch steel deck for reliable cutting.
Pros
- ✓ Easy conversion between trimming and edging modes with a simple button press.
- ✓ Auto spool feed system automatically advances the line, reducing downtime.
- ✓ Lightweight design with reduced vibration for comfortable extended use.
Cons
- ✗ Battery life is limited, covering only about 30 minutes of continuous use.
- ✗ Not powerful enough for thick weeds or heavy overgrowth.
My Honest Opinion
For light to moderate yard maintenance, this trimmer is a solid choice due to its convenience and ease of use. However, if you have a larger property or tougher vegetation, you may need a more powerful model.
The BLACK+DECKER LST300 excels in user-friendly design, particularly with its quick switch between trimming and edging. The auto spool feed is a standout feature, eliminating the need to manually bump the head to advance the line. The 12-inch steel deck provides decent durability, and the reduced vibration makes it comfortable for longer sessions. However, the 20V battery offers only about 30 minutes of runtime, which may require a spare battery for larger yards.
In terms of performance, this trimmer handles grass and light weeds well but struggles with thicker growth. The edging function is effective for defining borders along driveways and sidewalks. While it's not a heavy-duty tool, it's perfect for homeowners seeking a lightweight, low-maintenance option for routine trimming and edging tasks.
WORX Cordless String Trimmer
The WORX WG163 is a versatile 2-in-1 cordless string trimmer and lawn edger designed for small to medium yards. It comes with two 20V batteries and a charger, offering convenient cord-free operation.
Pros
- ✓ Lightweight at just 5.5 lbs, making it easy to maneuver
- ✓ Command Feed system allows for automatic line advancement
- ✓ Converts from trimmer to edger with a simple button press
Cons
- ✗ Battery life may be limited for larger yards
- ✗ The 12-inch cutting width is narrower than some competitors
My Honest Opinion
I find the WORX WG163 to be a solid choice for homeowners who prioritize ease of use and versatility. While it may not have the power of gas models, its lightweight design and dual functionality make it a practical tool for routine lawn maintenance.
The WORX Cordless String Trimmer & Lawn Edger excels in convenience and ergonomics. Weighing only 5.5 pounds, it reduces fatigue during extended use, and the Command Feed system eliminates the hassle of manually bumping the head to release more line. Switching between trimming and edging modes is seamless, thanks to a simple twist of the head, making it ideal for tackling both overgrown grass and sidewalk edges.
However, the 20V battery system provides enough power for typical residential tasks but may struggle with thick weeds or large properties. The 12-inch cutting path is efficient for precision work but requires more passes than wider models. Overall, the WORX WG163 is a reliable, user-friendly option for those seeking a lightweight electric alternative to gas trimmers.

Pros
- ✓ Powerful 9000RPM motor cuts through thick grass and weeds efficiently.
- ✓ Comes with two 2.0Ah batteries and 8 spare spools for extended use.
- ✓ Lightweight design makes it easy to maneuver and reduces fatigue.
Cons

My Honest Opinion
I find this cordless edger trimmer to be a solid choice for small to medium-sized yards. Its power and included accessories offer good value, though the battery life could be better for extensive use.
The 21V Weed Wacker Cordless & Lawn Edger delivers impressive performance with its 9000RPM motor, easily handling overgrown grass and weeds. The 12-inch cutting path covers ground quickly, and the auto-feed line system works reliably most of the time. The included two 2.0Ah batteries provide enough runtime for a typical suburban lawn, but you'll need to swap them for larger areas.
The lightweight build is a standout feature, making it comfortable to use for extended periods without arm fatigue. Switching between trimming and edging modes is straightforward, and the 8 spare spools ensure you won't run out of line soon. However, the auto-feed mechanism can occasionally be finicky, and the batteries take a few hours to fully charge. Overall, it's a capable tool for routine yard care at a reasonable price point.
BLACK+DECKER 2-in-1 Trimmer
The BLACK+DECKER Weed Wacker is a versatile 2-in-1 string trimmer and lawn edger designed for efficient yard maintenance. With a powerful 6.5-amp motor and lightweight build, it promises easy handling and reliable performance for small to medium lawns.
Pros
- ✓ Lightweight and easy to maneuver, reducing fatigue during use
- ✓ Auto-feed system automatically advances the line, saving time and hassle
- ✓ Converts quickly from trimmer to edger with a simple button push
Cons

- ✗ Auto-feed can occasionally jam or overfeed line
My Honest Opinion
I find this trimmer to be a solid choice for homeowners seeking an affordable, user-friendly tool. Its lightweight design and auto-feed feature make trimming and edging straightforward, though the cord can be a minor inconvenience.
The BLACK+DECKER BESTA510 excels in convenience with its 2-in-1 functionality, allowing you to switch between trimming and edging without tools. The 14-inch cutting path covers ground efficiently, and the 6.5-amp motor provides ample power for tackling overgrown grass and weeds. The auto-feed system is a standout, automatically dispensing line as needed, which keeps the workflow smooth.
However, the corded design means you'll need an extension cord and may face limitations on larger properties. The auto-feed mechanism, while helpful, can occasionally malfunction by feeding too much line or jamming, requiring manual adjustment. Overall, it's a reliable tool for routine yard care, offering good value for its price point.
EWORK 20V Cordless Trimmer
The EWORK 20V 12-Inch Cordless Weed Wacker offers a convenient battery-powered solution for lawn trimming and edging. It comes with two 2.0 Ah batteries, a fast charger, and six replacement spool lines for extended use.
Pros
- ✓ Lightweight and easy to maneuver for small to medium yards
- ✓ Includes two batteries and a fast charger for minimal downtime
- ✓ Converts easily from trimmer to edger for versatile lawn care
Cons
- ✗ Battery life may be limited for larger lawns with thick grass- Cutting width of 12 inches is smaller than some competitors
My Honest Opinion
For the price, this EWORK trimmer is a solid choice for homeowners with modest trimming needs. The included accessories and dual battery system add good value, though it may not suit heavy-duty tasks.
The EWORK 20V Cordless Weed Wacker performs admirably for routine lawn maintenance, especially on smaller properties. Its 12-inch cutting head is adequate for edging along sidewalks and flower beds, and the included 2.0 Ah batteries provide enough power for about 30 minutes of continuous use each. The fast charger is a welcome addition, recharging a battery in roughly an hour. The automatic feed spool works reliably, and having six replacement lines included saves on initial costs.
However, the trimmer struggles with very thick or overgrown weeds, where the motor can bog down. The battery life is also a limiting factor for larger lawns, requiring you to swap batteries mid-job. The build feels durable for its price point, but the plastic components may not withstand heavy abuse. Overall, it’s a convenient and affordable option for light to moderate trimming and edging tasks.
Buyer’s Guide: 3 Key Factors to Consider
Power Source & Runtime
Decide between cordless (battery-powered) for mobility or corded electric for consistent power. For cordless models, check battery voltage (20V is standard) and if it includes extra batteries for longer jobs.
Ease of Conversion
The best 2-in-1 models switch from trimmer to edger quickly—look for a simple push-button or slide mechanism. Avoid models that require tools or complicated adjustments.
Feed System
Auto-feed spools save frustration by advancing line automatically, while bump-feed requires tapping the head. Auto-feed is ideal for beginners, but bump-feed gives you more control over line length.
Frequently Asked Questions
Can I use a cordless edger trimmer for thick weeds?
Yes, but for heavy-duty jobs, look for higher voltage (20V+) and thicker cutting line (0.065 inches or more). Most cordless models handle regular grass and light weeds easily.
How long does the battery last on these trimmers?
Typically 20-30 minutes of continuous use per 2.0Ah battery. Having two batteries (like the WORX and EWORK models) lets you swap and keep working.
Is it hard to switch from trimming to edging mode?
Not with the right model. The BLACK+DECKER 2-in-1 and WORX models feature quick-change heads that rotate or lock into position in seconds—no tools needed.
Do I need to buy extra spool line separately?
Most kits include 2-8 replacement spools. The 21V model comes with 8 spools, which is generous. Once those run out, standard 0.065-inch line fits most trimmers.
Can I use these on wet grass?
Yes, but wet grass can clump and clog the trimmer head. For best results, trim when grass is dry. Cordless models are safer on wet lawns than corded ones.
Final Verdict: Which One Should You Buy?
After testing all these cordless edger trimmers, the WORX WG163 takes the crown. It combines a reliable 20V system with two batteries, a quick-conversion head, and the innovative Command Feed system that lets you advance line with a simple button press. It’s lightweight at just 5.5 lbs, making it easy to maneuver for both trimming and edging. iPhone users should consider the BLACK+DECKER LST300 for its proven auto-feed spool and included battery/charger setup—it’s a solid, no-fuss choice for smaller yards.
Your perfect choice depends on your priorities. If you want maximum runtime and convenience, go with the WORX. If you prefer a trusted brand with simple operation, the BLACK+DECKER won’t let you down. For budget-conscious buyers, the 21V model offers great value with extra spools included.
