This is a pretty impressive little air compressor. I use it to inflate my e-scooter tires once or twice a week. I've used it about a dozen times and it still has enough battery left. The best part is that it shows you the air pressure of your tire and then inflates to the desired preset pressure. I have it set to inflate until the pressure reaches 50psi. Once this happens, it stops blowing. Pretty cool. It even has a built-in LED light so you can work on your tires at night.
