Best Corded Weed Eaters for Trimming Around Your Yard
As an Amazon Associate we earn from qualifying purchases.
A corded weed eater draws power from a wall outlet through a cord, so its run time is set by the cord and the outlet, not by a battery. This comparison covers four corded trimmers that their listings describe as corded electric weed eaters or string trimmers. Each one is summarized only from what its own listing states, and the table and product sections show where a listing leaves a value out.
Quick answer
- The four corded models here are the BLACK+DECKER BESTE620, BLACK+DECKER BEST935, BLACK+DECKER BESTA510 and the DEKOPRO corded string trimmer.
- Three of them are BLACK+DECKER models with a 6.5 amp or 4 amp motor, and the listings name an automatic line feed on each of them.
- The DEKOPRO listing says the extension cord is not included, so budget for one.
- Cutting width ranges from 9 inches to 14 inches across the four listings. The wider deck covers more ground per pass, and the narrower one suits tight borders.
How a corded trimmer differs from a battery one
The choice between corded and battery power comes down to where you work. A corded trimmer never runs out of charge, so the listing’s runtime figures do not apply. The trade-off is the cord. You need an outlet within reach of the work area, and you need to keep the cord clear of the blade line. The listings in this group say little about cord length, so measure the path from your outlet to the far corner of the yard before you order.
A corded trimmer is also lighter than a battery model of similar size, because it does not carry a battery pack. The BESTA510 listing gives a weight of 6.3 pounds, and the DEKOPRO listing gives 3.3 pounds, which is a useful spread to compare against the battery models you may also be considering.

BLACK+DECKER BESTE620 Corded String Trimmer and Edger
The BESTE620 listing describes a 6.5 amp motor paired with the brand’s POWERDRIVE transmission, which the listing says gives maximum performance on tough weeds and overgrowth. Its headline line feature is EASYFEED, which advances the line with a push of a button and needs no bumping. The head converts to a wheeled edger by rotating it, and the listing says the wheeled edge guide helps you work along borders, sidewalks and flower beds. It has an adjustable handle and adjustable height, a premium soft grip and a cord retention system that the listing says prevents accidental disconnection. The title gives a 14-inch cutting width, and the listing carries a 2-year limited warranty. The listing does not give the cord length or the trimmer weight.
Choose this model when you want a 14-inch corded trimmer that also edges, and when push-button line advance matters to you.
BLACK+DECKER BEST935 Corded String Trimmer
The BEST935 listing describes a 4 amp motor and a 13-inch cutting swath. It says the trimmer uses auto feed to keep the line moving without manual adjustment, and it includes an AF-100 spool and a built-in auxiliary handle. The listing calls it lightweight and comfortable to use, and it gives a 2-year limited warranty. The motor is smaller than the 6.5 amp motors in the other BLACK+DECKER listings in this group, so the listing’s own numbers suggest a lighter-duty tool. The listing does not describe the tough-weed performance in the way the 6.5 amp listings do.
This model suits a small to medium yard with light trimming: borders, fence lines and the edges of a lawn. The listing gives no cord length or weight, so measure your outlet distance first.
DEKOPRO 2.2A Corded String Trimmer
The DEKOPRO listing names a corded string trimmer with a 9-inch cutting width and an 11,000 RPM motor. Its bullets say the trimmer weighs 3.3 pounds, which is the lightest figure in this comparison, and that its controls are simple enough for seniors and women to use without fatigue. The listing describes an automatic line feed that releases about half an inch of line each time you press the trigger, and a line-release button for extending the line by hand. It includes one built-in spool and two replacement spools. The listing says the trimmer is designed for long-term use, and it describes the 9-inch width as suitable for fences, sidewalks and garden edges.
The title and bullets both say the listing does not include the extension cord. That is a real cost to add, and the listing does not state the cord length you need. Budget for an outdoor-rated extension cord that reaches your work area. The listing does not give a warranty term, so ask the seller before you buy.
This model fits a light-duty job: edging along a walkway, trimming around a garden bed or cleaning up a fence line. Its narrow 9-inch width means more passes on a large open lawn.
BLACK+DECKER BESTA510 Corded Weed Wacker with Auto Feed
The BESTA510 listing describes a 14-inch cutting width, a 6.5 amp motor and an 8000 RPM speed. It states the trimmer is corded electric, which its specification sheet confirms. The bullets name the POWERDRIVE transmission, the automatic feed spool, a wheeled edger conversion and a cord retention system. The listing says the trimmer can trim grass in hard-to-reach areas where mowers cannot cut, and it describes edging along borders, sidewalks and flower beds. It weighs 6.3 pounds, and it carries a 2-year limited warranty.
Its specification matches the BESTE620 on motor and cutting width, so the choice between them comes down to the line-feed mechanism and the weight. The BESTE620 listing describes a push-button advance, while the BESTA510 listing describes an automatic feed spool. The listing does not say whether the two systems are the same part.
How to choose among the four
Start with the size of the area you cut. The two BLACK+DECKER 14-inch models, the BESTE620 and the BESTA510, cover more ground per pass than the 13-inch BEST935 or the 9-inch DEKOPRO. If you have a large lawn edge to trim, the wider cutting path saves passes.
Next, look at the motor. The BESTE620 and the BESTA510 both list a 6.5 amp motor. The BEST935 lists 4 amp. The DEKOPRO lists 11,000 RPM and does not name an amp rating, so the two numbers cannot be compared directly. Compare the motor description in each listing to the job, not just the number.
Then decide on the line feed. The BESTE620 uses a push-button system. The BEST935, the BESTA510 and the DEKOPRO each use some form of automatic feed. Any of these saves you from bumping the head on the ground, and the spool count varies. The DEKOPRO includes the most spare line in the box.
Last, check the weight and cord. The DEKOPRO is the lightest at 3.3 pounds, while the BESTA510 is heavier at 6.3 pounds. The cord length is not stated in any of the four listings, so measure first.
Cord and safety basics
A corded trimmer needs a safe, outdoor-rated cord connection. None of the listings give a full set of safety instructions in this comparison, so read the manual that comes with the trimmer. Keep the cord well away from the cutting head at all times, and plug in only after the trimmer is set up and the head is in position. The BESTE620 and the BESTA510 both list a cord retention system that helps stop the cord from pulling loose during use, which is a helpful feature when you are working around the yard.
Wear eye protection and sturdy shoes. The listings do not say what protective gear is required, but any string trimmer throws debris, so protect your eyes and legs. Keep children and pets clear of the cutting area.
Mistakes to avoid
- Buying the DEKOPRO without an extension cord. The listing says the cord is not included.
- Choosing the 9-inch DEKOPRO for a large lawn edge and then wondering why the job takes many passes.
- Assuming the BEST935 has the same power as the 6.5 amp models. The listing gives it a 4 amp motor.
- Ordering without measuring the outlet distance. None of the listings give a cord length.
- Treating the spool count as the same across models. The DEKOPRO names two extra spools, and the BEST935 names one AF-100 spool in its contents.
Relation to other trimmer types
If the cord is the limit for your yard, a battery model may be a better fit. The guide to top battery powered weed eaters compares cordless options with the same kind of listing detail. If you prefer engine power and do not mind the upkeep, the guide to 4-cycle gas weed eaters covers that category.
FAQ
Which corded weed eater has the widest cut?
The BESTE620 listing gives a 14-inch cutting width in its title, and the BESTA510 listing also gives 14 inches. The BEST935 listing states a 13-inch cutting swath, and the DEKOPRO listing states 9 inches.
Which one is the lightest?
The DEKOPRO listing gives a weight of 3.3 pounds, and the BESTA510 listing gives 6.3 pounds. The other two listings do not state a weight, so the DEKOPRO is the only one with a verified low figure here.
Does any of these include an extension cord?
The DEKOPRO listing says the extension cord is not included. The other three listings do not mention a cord in their contents, so assume you will need a cord for each and check the listing before you order.
Which model has automatic line feed?
All four listings describe some form of automatic or auto feed. The BESTE620 uses EASYFEED, a push-button advance. The BEST935 uses auto feed with an AF-100 spool. The BESTA510 uses an automatic feed spool. The DEKOPRO uses an automatic line feed that releases line when you press the trigger.
Do these trimmers have a warranty?
The BESTE620, BEST935 and BESTA510 listings each give a 2-year limited warranty. The DEKOPRO listing does not state a warranty term, so ask the seller before you buy.
Is a corded model better than a battery model?
It depends on the job. A corded trimmer has no battery to charge or replace, so runtime is not a concern. It does need an outlet and a cord, so a battery model suits a yard with no convenient outlet near the work area. The choice depends on your layout, not on a single rating.
Bottom line
For a 14-inch corded trimmer with a 6.5 amp motor and an edging conversion, choose the BESTE620 if you want push-button line advance, or the BESTA510 if you prefer an automatic feed spool and a slightly lighter feel. For a light-duty trimmer with the lightest listed weight in the group, the DEKOPRO is the one to check, but budget for the extension cord. Measure your outlet distance before you order any of them.
