NMaverick Tested it today with a professional tire meter for air. It is inconsistent and the meter is wrong. I Inflated my car tires to 32 PSI and metered them against a professional meter. There was 4-2 PSI difference towards up (results varied per tire from 34.5 to 36 PSI). Not suitable for this kind of precision. To make things worse, after inflating all four tires, the pump started to smoke. As I read afterwards you need to let it cool after 5-8 minutes of use. This is ridiculous if you take into account that you need as much to inflate a flat bike tire, let alone a car or motorbike. This is completely useless for inflating, but could be used as a very fat flashlight and powerbank.
