The instructions are very hard to understand. I know its just a portable tire inflator however getting the thing charged and ready for use is a challenge if using their instructions. There was not a supplied USB charging cord, so I plugged it into AC power and got nothing. Waited a full night and still nothing. The unit is quite small, not sure how it works because...well it didn't. I see issues with the cord that goes into the car for use off car battery as it seemed short and flimsy. Spend an extra 20.00 and get a good quality pump.

This inflator only works if it's plugged in to a power source. Internal battery refuses to hold a charge and thus makes it no longer portable.

Used it when I got it to check it worked, then put it in my car. After 6 months I had a flat tire and it didn't work. Battery states full but it starts then immediately dies and turns off even while plugged into an outlet. I wouldn't relay on this if you need it for emergencies.

Initially worked good. But after 2 uses not charging anymore. Cannot reach manufacturer. So, basically waste

Only thing i'd use this for is blowing up balls or bike tires but that's pushing it tbh.. As for use on actual cars though... it's a definite hell no Full charge, plugged in, first use motor died after 7ish mins of use gave it a break tried again, it started up when i was testing it but once I put it back on the tire it gave out. And no it wasn't stopping because it was on the target psi it had 8 more psi to go FAIL For those of you who are thinking of purchasing for auto emergency use don't screw yourself with this purchase

is not Cordless Rechargeable

Used one time and quit working way after the return window.

Stopped working after 1st use

Compressor outlet plug-in failed after very little use. Poor quality product. Return window is 30 days. Do not buy.
