The Hoto Air Pump Master is a multifunctional electric air compressor for tires, boards, tents and almost any other inflatable gear. It is powerful and still easy to carry and store. You can set the pressure with a digital control from 3 to 150 psi. The pump stops automatically at the set pressure and remembers your last setting for the next time you use it. You can use it for bikes, e-bikes, motorcycles, car tires, balls, SUP boards, tents, pools and other inflatables. The strong built-in lithium battery gives power for many uses and recharges fast via USB-C or a 12V car plug. A small indicator shows the charging status. The set includes Schrader, Presta, Dunlop, quick release, needle and other valve adapters, a 75 cm high-pressure air hose for tires and a 100 cm high-volume air hose for large inflatables, plus a storage bag. This portable air compressor is great if you want a compact and strong pump for your tires and inflatables.
