Power Tank

Power Tank builds CO2 tire inflation systems for off-road and overland use. A high-pressure CO2 cylinder airs up four oversized tires in a fraction of the time an electric air compressor takes — no duty cycle, no overheating, no noise.

The catalog runs deeper than tanks: Super Flow regulator kits for the XP400 Pro and HP250i Comp series, the Big Kahuna Digital Ventoso RED inflator with quick-switch chucks, Power Shot tire repair kits, a nitrogen regulator kit for shocks, and dozens of brackets, from Bronco roll bar mounts to Four Wheel Camper propane-tank mounts.

The trade-off is refills — CO2 runs out, so know where your local fill station is. And measure your cylinder diameter before ordering a bracket; they are sized to specific tanks.
