EPAuto Tire Inflators & Air Tools

Two kinds of tools live here. The 12V inflators carry their own pump and plug into the lighter socket. The inflator gauge and air chucks connect to a compressor you already own.

The EPAuto 12V inflators are built for cars, bikes and midsize SUVs. They do not support light truck (LT) tires.

Tire & air questions

Can the EPAuto 12V tire inflator fill truck tires?

No. The 12V digital inflator supports cars, bikes and midsize SUVs with engines under 3.5 liters. It does not support LT or heavy-duty truck tires.

Does the EPAuto inflator gauge work without a compressor?

No. The 120 PSI inflator gauge is a gun, gauge and hose in one, and it needs an air compressor behind it.
