Our verdict
A simple plug-in inflator to leave in a car for top-offs. Truck owners and anyone who wants cordless use should look at the VIAIR or Fanttik.
Pros and cons
Pros
- Plugs into the car's 12 V socket: no battery to keep charged
- Stops automatically at the pressure you preset
- 2.2 lb and small enough to live in the trunk
- LED flashlight for roadside use at night
Cons
- 100 PSI and a 15-minute run limit suit car tires, not large truck tires
- Needs the car running or the socket live, so it is no help away from the car
- AstroAI's page gives no warranty term
