Four road tires on a single charge changes the math on electric inflators. Muc-Off's AirMach Mini Pro packs a 450mAh lithium-ion battery into a 122-gram aluminum body that fits in a jersey pocket, delivering up to 120 psi without the arm fatigue of manual pumping or the one-shot limitation of CO2 cartridges. The integrated LED display shows real-time pressure and battery level, eliminating the guesswork that comes with compact pumps that lack gauges. Set your target pressure, press the button, and the inflator stops automatically when it hits your number.

The Pro version upgrades from the original AirMach Electric Mini with a larger battery capacity, higher maximum pressure, and that pressure display. Where the original topped out at 100 psi and two tires per charge, the Pro pushes to 120 psi and handles four tires before needing a recharge. USB-C charging fills the battery in 30 minutes, so you can top it off during a coffee stop if you've been running it hard. The brushless motor handles the compression work, pushing air through the system without the reciprocating motion that wears out piston-style electric pumps.

The inflator head uses a knurled, anodized aluminum construction with a reversible design that fits both Presta and Schrader valves. For TPU inner tubes or plastic valve stems that can be damaged by heat buildup during inflation, the included AirHose extender creates separation between the motor housing and the valve. The kit also includes a ball inflation needle and toy nozzle for off-bike use, turning the inflator into a general-purpose tool for sports equipment or pool floats.... Read More
