The 12V compressor that actually fills RV tires.
Most portable compressors die trying to fill a Class B RV tire. The VIAIR 400P-RV is rated to 150 psi continuous and built specifically for high-pressure RV/truck tires. 33-minute fill time for a fully deflated 33" tire. Battery-clamp connection (don't try cigarette lighter for this much current).
What to look for
- 150 psi max working pressure (most portables max at 100)
- 2.30 CFM free flow
- 33% duty cycle at 100 psi
- 30-amp inline fuse + battery clamps
- Carries in included canvas bag
- Sand tray base (won't sink in soft surface)
