Review on YTA Portable Mini Air Inflator Hand Held Tire Pump 2000mAh - Digital LCD LED Light - Max 150 PSI Inflation - for Ball, Car Bicycle Tire & More by Drew Diaz

Accuracy - 1 Durability - 1 Ease of use - 10 It worked once. When it arrived I read the instructions and loaded it up. I set the PSI to 33 and let it run. When it turned off I checked the tire with a tire pressure gauge which read 42. Once I had deflated and checked the pressure readings again, I recharged the compressor. As I approached the next tire, I accidentally dropped it from about tire height and it broke.
