Regardless of whether a car is powered by electricity or gasoline, it has tires. And those tires can go flat and lose pressure over time. The One Pro portable tire inflator works fast, has a massive battery, and accurately inflates flat or low tires to the specified pressure. The compact, tough exterior has a digital LCD display with a simple push-button interface that shows settings and real-time information like pressure and mode. Power comes from a 10,400mAh battery with 400 days of standby time, and can inflate a standard 225/60R18 from completely flat to 35 PSI in under three minutes, with an 80-100% of less than 50 seconds. Built into the One Pro is an LED flood light with strobing SOS mode and a USB-C charging port.
