Compact and convenient for camping, or commuting - it's the power-packed rechargeable pump that's perfect anywhere power is at a premium -- like at the park, at the pool, or on the road. Keep tires at the perfect pressure, inflate a bike tire, pool float or sport ball in seconds. Simply set the PSI on the digital display and pull the trigger. The 24V-AJC-MAX automatically stops at your preset pressure.
