Over inflates by 2 psi (target 33 psi)
Reviewed in the United States on March 4, 2020
It over inflates tires by 2 psi based on readings from an analog pressure gauge and the vehicle TPMS (tire pressure monitor system) which both match. It is not accurate to the tenths of a psi, but only 0.5 psi. It already has slight fraying at hose end where it meets valve connector. LCD screen is poor quality with a rainbow effect and is difficult to read so not sure how it will hold up which could make it useless in the future. LCD is not back-lit either so filling tires at night could be difficult. Auto shut off seems to work, but there is a "delay"--it will continue to pump while readout shows it is at set pressure - but turn it off and reading can drop - so this seems like a feature more than a bug. I own a Tacklife volt-meter so thought this would be good quality. Overall disappointed for the $38 spent. Able to top off all four tires (so far, unlike some other reviewers) and it is reasonably quiet and fast for the size. I will probably return it for a more reliable and possibly less expensive tire inflator. I have a Jeep Cherokee KL Trailhawk, so airing up and down when going off/on-road may be a common event. I also want a unit I can trust in case of emergency even though I have a full size spare. For now I know to set it to 31 psi if I want 33 psi and then double & triple check with analog gauge and tpms. Not ideal.
