1 / 7Greenworks 21212 4 Amp Corded String Trimmer
The Greenworks 21212 string trimmer is a corded electric model listed with a 4 Amp rating and a 13-inch cutting path in its title. It suits routine trimming where a power outlet is accessible, but the listing’s motor, cutting-width and dimensions details conflict, so confirm the selected configuration before buying.
At a glance
- Corded power avoids battery changes during use, though the work area needs access to an outlet and a suitable extension cord.
- The title identifies a 13-inch cutting path and automatic dual-line feed. Other feature text gives conflicting cutting-width claims.
- The feature text describes a telescoping adjustable shaft and ergonomic grip for adapting the handle to different users.

- Automatic dual-line feed is described as advancing line during operation, reducing manual adjustment stops.

What to know before buying
Listing details to confirm
Listing details are contradictory or unconfirmed: the title and size field say 4 Amp and 13-inch cutting path, while feature text claims a 5.5 Amp motor, a 15-inch swath and an additional 13-inch width entry. The structured cutting-width field says “1300 inches.” Dimensions are also inconsistent, listed as “100.5L x 25W centimetres” and “100.51 x 24.99 x 11 cm; 3.18 kg.” Confirm the exact configuration and dimensions with the selected listing before purchase. The description says the power cord is not included, so plan to provide a suitable cord.
Who is it for?
A good fit for
- Homeowners doing routine grass trimming in small to medium-sized yards with an outlet nearby.
- Buyers who prefer corded operation over managing batteries or fuel.
Less suited to
- Users needing unrestricted movement away from an outlet or who do not want to manage a power cord.
- Buyers needing a confirmed cutting width or motor rating without first resolving the listing discrepancies.

Customer feedback describes the trimmer’s performance positively, while reporting mixed impressions of quality, line removal, value and weight. For buyers considering routine trimming, this feedback makes ease of handling and line management worth weighing alongside the listed 3.18 kg weight and automatic-feed claim. Those listing claims do not establish that every user will find the trimmer light or line changes straightforward.
Positive themes
- Customer feedback describes trimming performance positively.
Mixed feedback
- Feedback is mixed on product quality, line removal, value and weight.
Frequently asked questions
Does the trimmer run on a battery?
No battery configuration is listed. It is identified as corded electric, so it needs an outlet and a suitable cord.
What is the cutting width?
The title and size field say 13 inches, but feature text also claims 15 inches and the structured detail gives “1300 inches.” Verify the cutting width for the selected listing.
Is a power cord included?
The product description states that the power cord is not included.
