Is the Kimo cordless ratchet strong enough for lug nuts?

With 89 ft-lbs it can loosen many car lug nuts, but heavily torqued or rusted nuts may still need a breaker bar first. Always finish tightening with a torque wrench.

How long does the battery last?

Run time depends on load, but the kit includes two 2.0Ah batteries so you can swap one in while the other charges. Expect the pair to cover most routine repair sessions.

Does it have variable speed?

No. It runs at a single 400 RPM, so control comes from pulsing the trigger rather than a speed dial.

What sockets fit this ratchet?

It uses standard 3/8-inch drive sockets, the same size as most air ratchets and hand ratchets.

What comes in the box?

The kit includes the ratchet wrench, two 20V 2.0Ah lithium-ion batteries, and a charger.

Is it better than an air ratchet?

It removes the need for a compressor and hose, which suits home garages. Air ratchets are usually lighter and faster, so pick based on whether you already own a compressor.
