What to know before buying

Listing details to confirm

Listing details are contradictory or unconfirmed: the title and description claim two 21V 4.0Ah batteries, but the explicit included-components field specifies a 21V, 4.0AH battery without a quantity. Speed claims also conflict, with 2800 RPM in the details and 0–3500 / 4500 / 5500 RPM in the feature text. The maximum torque is a listing claim, and customer reports of power are mixed, so confirm the selected listing and suitability for the intended fasteners.

Customer feedback highlights perceived functionality, battery life and durability, including a report of removing rusty wheel nuts. Opinions on power and ease of use are mixed, with some customers saying the wrench does not match its advertised specifications. That matters here because the 1200 Newton Meters figure is a listing claim rather than an independently established output, and the speed information is inconsistent. Aggregate ratings are mostly five-star but include a notable one-star share, so they do not settle whether this tool will meet a particular workload.

Frequently asked questions

What batteries are included?

The title and product description claim two 21V 4.0Ah batteries, but the detailed included-components field lists a battery without a quantity. Confirm the kit contents before buying.

What speed does it reach?

The details list 2800 RPM, while the feature text gives 0–3500 / 4500 / 5500 RPM for three settings. These figures conflict, so treat the speed specification as unconfirmed.

Which sockets are listed?

The included-components information names five sockets: 17 mm, 19 mm, 21 mm, 22 mm and 24 mm, plus an extension bar.
