3.4/5
For Jeep and small-truck owners on stock or 31 in tires who want a cheap clamp-on compressor for airing up. Bigger tires call for the 2781 or a VIAIR 400P.

Pros
- Runs 40 minutes at a stretch, enough to air up all four tires after the trail
- Long 24 ft coil hose reaches every tire from the engine bay
- Clamps to the battery, so no blown socket fuses
- Much cheaper than the bigger 2781
Cons
- Half the airflow of the 2781: slow on 33 in and larger tires
- No auto shutoff, so you have to watch the gauge
- Only a one-year warranty
