AirTube was developed to facilitate stress-free pumping of bicycle tyres in case of a flat on a trip. It looks like a regular mini-pump but is operated electrically, powered by a lithium battery. When fully charged, it can pump about two 700 × 25 road tyres up to 120 psi or about three 27.5 × 2.5 mountain tyres to 35 psi. A stylish one-inch gauge provides precise pressure reading. It comes with an USB type C charging cable to recharge at any place and any time.
