This works well, though it does get really hot quickly, so be cautious.

Within minutes, it was filled!

It takes longer to inflate than advertised, but for $ 20, I have no complaints.

It works well and inflates quickly, although the cord gets a bit warm. This was easy to use and inflated my car tires to the correct pressure accurately.

All in all, it did the job well. My old inflator's plug broke, but this one plugs into the 12V adapter, so I don't have to worry about charging it. You can set the psi value on the LED screen.
