Overview
The Dong DCPB488DM is a 20 volt cordless impact tool weighing 2 kilograms, with a 4.6 average rating across 240 ratings.
20 volt is a common cordless platform size for impact drivers and impact wrenches, and at 2 kilograms this leans toward the heavier, higher torque end of that category rather than a compact one handed driver. No description or torque figure is listed, so which fasteners it is rated for is not spelled out.

Who it's for
