NEXPOW Tire Inflator Portable Air Compressor, 150 PSI Portable Tire Pump for Car, Motorcycle, Bike, Ball

Although I have had the NEXPOW only a few days it does appear to be a quality product. I really like that it is battery powered in addition to having power from the dc charger in the auto. Adequate accessories especially the value stem converter for bicycle tires.

I bought this to replace one that I previously purchased that broke during first use. I was able to quickly inflate all my tires to 38 psi. One was 11.5 psi (because of the previous tire inflator I bought and broke) and the other 3 were 31.5 psi. I didn't charge the battery before use and used the 12 volt adapter instead. I plugged into my console and the cord was long enough that I could take it out the driver or passenger door and reach both tires on that side. I like that the nozzle screws on to the tire stem. My previous inflator had the kind where you lock it in place with a valve which broke when trying to use. I basically screwed it on each tire, set the pressure for the first one and turned it on. It automatically shuts off when the pressure you set it at is reached. I hope I don't have to use it again but I'm prepared now if my tires get low again.
