Look at this handy tire inflation pump. It is a compressor powered by a lithium-ion battery. The battery can be charged either from a wall outlet or from portable chargers. This compressor allows you to quickly inflate your tires on the road, in the garage, parking lot, or anywhere else. The pump has a digital pressure gauge to monitor the pressure. On it you can set a threshold, reaching which the pump will automatically shut off. The kit comes with all the necessary attachments and adapters, so you'll have no trouble inflating a mattress, lap, boat, pool or anything else.
