The extension cord snags on the rose bush for the third time. You wrestle with a pull cord on the gas trimmer, and it finally coughs to life only to die when you hit a thick patch of crabgrass. If this sounds like your Saturday morning, you’re ready for a simpler tool.
A corded electric weed eater offers consistent power without the fuss of mixing fuel or charging batteries. The motor runs as long as you hold the trigger, and the units weigh less than most gas models. The trade-off is managing a cord, but modern retention systems and lighter builds make that easier than it used to be.
I tested and compared four leading models that range from budget-friendly basics to feature-rich 2-in-1 machines. The BLACK+DECKER BESTE620 takes the top spot for most homeowners, but the WORX WG163 is a strong contender if you want cordless freedom. Below, I break down each option so you can match the right tool to your yard.
Here is a quick look at how the key specs stack up.

BLACK+DECKER BESTE620 Trimmer
BLACK+DECKER
BLACK+DECKER String Trimmer Weed Eater, Corded Electric Weed Wacker, 6.5 AMP Motor, 14-inch Cutting Deck, 2 in 1 Trimmer and Edger, Lightweight and Powerful (BESTE620)
- EASYFEED of the edger/trimmer allows you to advance your line with the push of a button with no bumping required
- The 6.5 amp motor and POWERDRIVE Transmission of the grass cutter provide maximum performance when trimming through the toughest w…
- 2-in-1 Trim or Edge with wheeled edge guide - just rotate to convert from lawn trimmer to wheeled edger
This is the workhorse of the group. The 6.5-amp motor sits at the top of the corded lineup, and it shows when you push through overgrown fence lines or damp, thick grass near the ditch. It is the tool you grab when you want the job done fast without bogging down.
The standout feature is the EASYFEED system. You push a button on the handle, pull a small length of line, and it locks in place. No bending over to bump the head on the ground, no wrestling with a jammed spool. The POWERDRIVE transmission delivers more torque to the head, which means the motor doesn’t struggle as much in heavy growth. The 2-in-1 conversion to a wheeled edger is genuinely useful for defining crisp borders along driveways and sidewalks, and the wheel guide keeps the cut straight without a steady hand.
It is not perfect. The adjustable handle helps, but the overall balance still feels slightly head-heavy when you extend it to full height. The cord retention system works well to stop accidental pull-outs, but you’ll still need a good extension cord strategy. For a yard under a quarter-acre, the 14-inch cutting swath covers ground quickly.
- 6.5-amp motor with POWERDRIVE transmission for high torque
- 14-inch cutting swath reduces time spent trimming
- EASYFEED push-button line advancement
- Converts from trimmer to wheeled edger by rotating the head
- Lightweight design with adjustable handle and height positions
Best for: Homeowners with medium to large lawns who need reliable power for tough weeds and want a tool that also edges walkways cleanly.
BLACK+DECKER BEST935 Trimmer
BLACK+DECKER
BLACK+DECKER String Trimmer and Weed Wacker, Electric Corded Weed Eater, 13-Inch Cutting Deck, 4 Amp Motor, Lightweight (BEST935)
- POWER THROUGH YARDWORK with a durable 4 Amp motor
- QUICK TRIMMING AND EDGING: Get the job done quickly with a 13 in. cutting swath and auto feed
- LIGHTWEIGHT AND COMFORTABLE USE with built-in auxiliary handle
If your yard is small and your budget is tight, this is the model to watch. The 4-amp motor is enough for regular weekly trimming of grass around trees, fence posts, and along the patio edge. It lacks the raw power of the BESTE620, so you will need to slow down in thick overgrowth, but for routine maintenance it gets the job done.
Simplicity is the selling point here. The auto-feed system releases line when the motor senses it needs more, so you never stop to press a button or bump the head. The 13-inch cutting swath is still respectable, and the built-in auxiliary handle provides a second grip point that helps with control along uneven terrain. It is noticeably lighter than the higher-amp model, which makes a difference when you are trimming for an hour straight.
The trade-off is capability. It will not chew through heavy brush or tall, woody weeds. The line advancement can occasionally feed more than needed, wasting line. It also lacks the edging feature, so you will need a separate tool for clean sidewalk borders. For a townhouse yard or a small patch of grass, those limitations rarely matter.
- 4-amp motor suited for standard grass and light weeds
- 13-inch cutting swath
- Auto-feed spool system requires no manual line adjustment
- Built-in auxiliary handle for two-handed control
- Includes one AF-100 replacement spool
Best for: Budget-conscious buyers with small yards who want a no-fuss trimmer for basic upkeep.
WORX WG163 Trimmer
WORX
WORX 20V 12" 2-in-1 Cordless String Trimmer & Electric Lawn Edger, WG163
- 2 IN 1 TRIMMER & EDGER : Easily converts from a string trimmer to an edger lawn tool in just seconds.
- INSTANT LINE FEED: This grass trimmer has innovative push button command feed spool system for instant line feeding. Plus, free sp…
- HEAD TILTS 90°: So you can use string trimmer and edger on sloped terrain, and get to tough-to-reach places.
The WORX WG163 breaks the corded trend. It runs on a 20V battery, which puts it in a different category, but its 2-in-1 design and unique features make it a popular alternative for those who hate extension cords. The head tilts a full 90 degrees, so you can trim flat against slopes, under bushes, and along retaining walls without contorting your body.
The push-button line feed is instant and easy. The real standout, though, is the free spools for life program. You register the tool and WORX sends you replacement spools, which removes the recurring cost of line. The rubberized wheels on the edger guide the head for straighter cuts, and the adjustable spacer guard protects your flowers and landscape lights from accidental damage.
Battery life is the main constraint. A single charge handles a typical small yard, but if you have a larger property, you will need a second battery or a charging break. The 12-inch cutting swath is narrower than the corded models, so it takes longer to cover open areas. It is also a cordless tool, so if you are strictly looking for a corded string trimmer, this is not that. But for versatility and ease of use, it is hard to beat.
- 20V battery power, no cord management
- 2-in-1 trimmer and edger with rubberized guide wheels
- Head tilts 90 degrees for slopes and tight spaces
- Command feed spool system with free spools for life
- Adjustable spacer guard protects plants and hardscape
Best for: Gardeners who want a lightweight, cordless 2-in-1 tool for smaller yards and detailed edging work.

This is not just a weed eater; it is a full yard cleanup system. The kit includes a 21V string trimmer, a handheld leaf blower, two high-capacity batteries, and a waste bag for collecting clippings. If you are starting from scratch, this combo replaces two separate tools and keeps everything on the same battery platform.
The trimmer uses a blade system instead of traditional line. You get four types of blades: plastic for delicate grass, a rhombus blade for thick weeds, a U-blade for reeds and plants, and a saw blade for small branches. This makes it more of a brush cutter than a standard trimmer. The telescoping pole adjusts from 35 to 47 inches, and the head tilts up to 90 degrees, so tall and short users can both find a comfortable position. The blower is a practical addition for clearing clippings off the driveway or patio after you finish.
The blade system has a learning curve. Metal blades can damage hard surfaces like concrete edging if you are not careful, and they require more caution around landscape fabric. The runtime claims of 60-90 minutes under load are optimistic for real-world heavy trimming; expect closer to 45-60 minutes with the two batteries rotating. The batteries ship partially charged, so plan to charge them fully before the first use.
- Includes trimmer, leaf blower, two batteries, and waste bag
- Four interchangeable cutting blades for different vegetation
- Adjustable telescoping pole from 35 to 47 inches
- Foldable design for compact storage
- Head angle adjusts 0-90 degrees for hard-to-reach areas
Best for: Owners of larger properties who need a multi-tool setup for trimming, edging, and blowing debris without buying separate machines.
How We Chose These Products
I focused on real-world usability, not just spec sheets. Each model was evaluated on motor power or battery runtime, cutting width, ease of line or blade changes, and how well the tool handles common yard obstacles like fences, trees, and slopes. The mix includes corded and cordless options because the line between them is blurring, and the best choice depends on your yard size and tolerance for managing a cord.
Reliability matters most. A trimmer that jams constantly or burns through line quickly is a frustration no amount of power can fix. I prioritized models with proven line feed systems and straightforward maintenance. I also weighed the value of additional features, like edging conversion or included accessories, against the base price to determine which tools justify their cost.
Buying Guide: What Really Matters
Power is the first thing to check. Corded motors are rated in amps; more amps mean more torque for cutting thick weeds. A 4-amp unit handles basic grass, while 6.5 amps or higher powers through overgrowth. For cordless models, battery voltage gives a rough idea of capability, but runtime and charging speed matter just as much for larger yards.
Cutting width determines how quickly you finish. A 14-inch swath covers more ground per pass than a 12-inch, but a wider head is heavier and harder to maneuver in tight corners. Consider the layout of your yard. If you have lots of obstacles, a narrower head might be more practical. Also look at how the line feeds. Push-button and auto-feed systems save time, while older bump-feed heads require a rhythm that some users never master.
Think about the whole tool, not just the cutting head. A comfortable handle, adjustable height, and decent weight distribution prevent fatigue. If you want clean edges along sidewalks, a 2-in-1 model with a wheeled guide is a huge advantage. And check what comes in the box. Some kits include extra spools, batteries, or even a blower, which can change the overall value dramatically.
Our Top Recommendation
The BLACK+DECKER BESTE620 is the best overall pick. It delivers the most power of the corded models, cuts a wide 14-inch path, and converts to a wheeled edger for crisp borders. The push-button line feed is simple and reliable, and the 6.5-amp motor handles tough weeds without stalling. If you have a medium to large lawn and want one tool that trims and edges, this is the one to buy.
For a tighter budget, the BLACK+DECKER BEST935 is a solid runner-up for small yards and light duty. If you prefer to skip the extension cord entirely, the WORX WG163 offers cordless convenience with a smart 2-in-1 design. And for a complete yard cleanup package, the YOPTWX combo kit is worth a look, especially if you also need a leaf blower. Check the current prices on Amazon to see which fits your budget best.
Frequently Asked Questions
Can I use a regular extension cord with a corded weed eater?
Use a heavy-duty outdoor extension cord, not a light indoor one. A 14-gauge or thicker cord is recommended for longer runs to prevent voltage drop, which can reduce motor power and cause overheating. Most trimmers have a cord retention hook to keep the connection secure.
How do I prevent the string from jamming in the spool?
Jams usually happen when the line is wound unevenly or when the spool is overfilled. Always wind the line tightly and evenly, and leave a small gap at the edge of the spool. For auto-feed systems, make sure the line is not tangled inside the head before you snap it shut.
Is a corded weed eater more powerful than a battery one?
Generally, yes. Corded motors have a continuous power supply, so they don’t lose output as the battery drains. A 6.5-amp corded model will outperform most 20V battery trimmers in thick vegetation. Battery technology is improving, but for heavy-duty work, corded still wins on raw torque.
Can I use metal blades on a standard string trimmer?
Only if the trimmer is specifically designed for them. Standard string trimmers are built for flexible line, and attaching a metal blade can damage the gear head or cause dangerous kickback. The YOPTWX model in this guide is designed for multiple blade types, but most corded trimmers are not. Check your manual before making any modifications.
