This weighs less than lunch.
You preselect, on the built in digital pressure Guage, the pressure you want your tire at, attach the short air hose, turn this on, and walk away. It shuts off when the pressure is reached.
It also inflates Inflatsables© like couches and air mattresses.
The other compressors mentioned here are complicated or require 110v or 12v cord or long obstinate air hoses to be dragged around.
It doesn't get simpler, and the battery also fits flashlights and a 3gallon vacuum and 160 other tools. That little bag is the compressor, battery, charger and a flashlight, the bigger thing next to it is a 3gallon wet/dry vacuum powered by the same battery.
Life can be simple.....
