accelerated air volume and speed to help you get back on the road more quickly Thanks to enhancements that provide 45.4% better inflation performance when fully charged, you can fill your tires up to eight times. Up to 150 psi of pressure can be supported by the high precision cylinder block. The alloy-based high-precision cylinder block can be used with both high-pressure tires on road bikes and shock absorbers on mountain bikes because it can inflate from 0 psi to 150 psi in just 20 seconds. The use of highly precise air pressure sensors eliminates the need for manual pumps. Tire pressure checks during inflation are eliminated thanks to digitally controlled air pressure sensors, which increase inflation accuracy to ±1 psi. For added convenience and comfort, set the tire pressure beforehand. The Xiaomi 1S
