The Protmex is a 3/8-inch cordless ratchet wrench built around a 21V brushless motor that delivers up to 74 ft-lbs of torque and 0-400 RPM variable speed. It ships as a kit with two 2.0Ah lithium batteries, a fast charger, eight metric sockets, a 1/4-inch drive adapter and a 3-inch extension bar. The slim ratchet head and built-in LED light target engine bays, under-seat work and other tight spots. Against corded and air ratchets it trades peak torque for portability; against premium cordless ratchets it gives up refinement and brand support but includes two batteries where many rivals ship one.

Ratings average 4.1 out of 5 across 25 buyers, a small sample that points to a generally satisfied but not unanimous reception. Owners tend to value the two-battery kit and the reach into tight spaces; the limited feedback makes long-term durability hard to judge.
This is a 3/8 inch cordless electric ratchet wrench powered by a 21V brushless motor. It delivers up to 74 FT-LBS (100 N.m) of maximum torque and 0-400 RPM variable speed for tightening and removing bolts.
The ratchet head is slim and compact, so it can reach into tight, narrow spaces such as engine bays, under seats and around machinery. A one-touch forward/reverse switch changes direction quickly, and a safety lock helps prevent accidental activation. A built-in LED work light illuminates dim work areas, and the soft insulated grip gives comfortable control during long use.
The kit includes two rechargeable 2.0Ah lithium batteries and a fast charger. It is used for automotive repair, motorcycle maintenance, bicycle assembly, equipment installation, home improvement and general garage fastening projects.
