New upgrade tire inflator, 4 important upgrades. More powerful, more durable, faster, and less noisy. This air compressor can inflate your tires with the 35L/m and can inflate the 195/55/R15 tire from 0 PSI-36 PSI in 4-5 minutes. The tire inflator will shut off automatically once reaches the pre-set value. (Please make sure the pre-set pressure is higher than the current pressure of the tires.) The portable features are also present in the storage function of the back. The storage function design of the pump makes your inflation experience better. Ultra-long power cord makes inflation almost available anywhere and anytime. The car tire pump is attached with an LED light, which is more convenient to operate in the dark. It also allows you to read and work at night simultaneously.
