Review on 🚗 FUMOSI Portable Cordless Air Compressor Tire Inflator - 150PSI with 2000mAh Power Bank, Digital LCD, LED Flashlight, SOS Alarm Light - Ideal for Car tires, Bicycles, Motorcycles, Balls, Pool Toys, Swim Ring by Dan Buycks

I give this device a 3 because it really works. But I would never recommend this for cars or motorcycles in the US. It's crazy that this device doesn't measure the pressure of car tires or MC tires in psi. It uses bars that are not common in the US. NOTE: US vehicle/vehicle manuals list recommended tire pressures in psi. Although the instructions provide a conversion from 14.5 psi to 1 bar, it would be difficult for an American driver to calculate the conversion for his vehicle. In addition to this problem, the device took about 1 hour for each 8-9% charge. So it took over 4 hours to go from 65% out of the box to 100%. Note. When inflating a car tire, the tube gets hot. And using psi instead of a bar doesn't turn it off automatically. Only if you use a bar will it be turned off in your settings. Also, we went from 35psi to 37psi for a car tire and used 10% battery. My husband set it to 36 but because he was using psi instead of a bar it didn't turn off automatically. So you can use auto-psi, but you have to turn it off manually.
