21V 3-in-1 Cordless String Trimmer vs WEN ET1003 Corded String Trimmer

The WEN ET1003 is the safer pick for most people: a simple corded trimmer with a 10-inch cut, automatic line feed, a rotating handle for edging, and a two-year warranty. The 21V 3-in-1 offers more versatility with two batteries, a brushless motor, a telescopic shaft, and a metal blade for heavier weeds, but it comes from a no-name brand with only 17 ratings. Choose the WEN if you have an outlet near the yard and want a light, proven tool. Choose the 3-in-1 if you need cordless freedom and want edging and brush clearing from one tool.

  • Choose the 21V 3-in-1 if you want cordless trimming away from outlets, two batteries for longer runtime, and a metal blade for thick weeds and brush.
  • Choose the WEN ET1003 if your yard is within reach of an extension cord and you want a light 4.4-lb trimmer with automatic line feed and a two-year warranty.

What reviewers say

21V 3-in-1 Cordless String Trimmer

  • 5 / 517 ratings

Buyers rate it highly and mostly praise the three-in-one flexibility, the two included batteries and the adjustable shaft and handle. Complaints center on runtime and on the tool being suited to light yard work rather than heavy growth.

What people mention
  • VersatilityPraisedOwners like having trimming, edging and light mowing in a single cordless tool.
  • Battery lifeCriticisedRuntime is short, and heavy cutting drains the 21V packs quickly.
  • PowerMixedFine for grass and light weeds, but it struggles in thick brush.
  • AdjustabilityPraisedThe telescopic shaft, 180-degree handle and 90-degree head make it easier to reach edges and slopes.

WEN ET1003 Corded String Trimmer

  • 4 / 528 ratings

Rated 4 out of 5 from 28 ratings. Owners treat it as a light, simple trimmer for small jobs, and the automatic feed and low weight come up as the practical strengths.

What people mention
  • WeightPraisedOwners like that it is easy to carry and swing for a whole trimming session.
  • Line feedPraisedThe automatic feed keeps line out without stopping to bump or rewind.
  • PowerMixedFine for grass and light weeds, but thick or tall growth slows it down.
  • CordCriticisedBeing tied to an extension cord limits where it can go and adds drag.

Questions and answers

Which is better for a small yard?
The WEN is easier for a small yard with a nearby outlet. It is light, feeds line automatically, and edges with a twist of the handle. The 3-in-1 makes more sense if outlets are far from the grass.
Which handles thick weeds better?
The 21V 3-in-1, because it ships with a metal blade and a saw blade for brush. The WEN uses 0.05-inch string, which struggles with woody stems.
Which lasts longer?
The WEN has a two-year limited warranty and stocked replacement parts, which is a clearer long-term bet. The 3-in-1's lifespan depends on its batteries, and no warranty is stated.
Is the 3-in-1 worth stepping up to?
Yes if you need cordless use, edging and brush clearing from one tool. No if you mainly trim grass near the house, where the WEN is simpler and lighter.
Can the WEN trim along a fence line?
Yes, but you drag an extension cord along. The 3-in-1's telescopic shaft and 180-degree handle make fence lines and under-deck edges easier without a cord.
Do I need two batteries?
Two batteries let you swap and keep working when one drains. The WEN never needs charging, but it always needs a cord and outlet.
