this is a popular thread this week. I bought one of these. from Amazon for my "me to me" Christmas present. For my first test I filled Six 15" trailer tires from 20psi up to 55psi, put a couple PSI in my RV tires, topped off 2 cars that were a little low and my motorcyle tires. that used about 40% of the battery. But not sure about the 100psi you asked for. And its simple, set the pressure on front, press button 2x (1 to check pressure, 1 to inflate tire) and it turns on until it hits your pressure and shuts off. small enough to carry around under the seat of truck.
