Overview
Running on a 7.2 volt battery pack at up to 3000 RPM, the Fanttik REX K2 APEX is a compact cordless impact tool rated 4.5 out of 5 across 43 reviews, with about 100 recent monthly purchases.
At 7.2 volts, this is built for compact, one-handed impact driving rather than heavy fastening work; the low voltage and RPM figures point toward smaller fasteners and lighter-duty jobs rather than automotive lug nuts or structural bolts. Fanttik is better known for portable air compressors, so this impact tool is a newer addition to that lineup.

Who it's for
DIYers and light-duty users who want a small cordless impact driver for household fasteners, furniture assembly or hobby projects. It is not sized for heavy automotive or construction fastening, where higher voltage impact wrenches are the norm.
