The video shows me inflating a tire from 30 PSI to 35 PSI after which the unit will automatically shut off. The light used is an air pump light, which is very convenient. Also doubles as a battery if you want to use it to charge your phone. A great gift for frequent drivers or for those living in Florida as the constant weather changes here cause tire PSI drops. There are also attachments for the bike and balls in the kit, the attachments are in a compartment inside the device which is nice as it makes them harder to lose. The battery of the device is 2200 mAh. Charges from zero to full in about 5 hours. It may get warm during use. I would not recommend using 0 PSI to 35+ in a continuous session, it takes 1 minute to cool down.
