- Small and light enough to live under a seat at under 5 lb
- Clamps straight to the battery, so no blown 12 V socket fuses
- Long 16 ft hose reaches all four tires from the engine bay
- Cheapest of the clamp-on compressors
- Slowest heavy-duty pick: fine for car tires, tedious for big truck tires after airing down
- No auto shutoff: you watch the gauge and switch it off
- Has to be clamped to the battery under the hood with the engine running
