Review on AKASO Tire Inflator: Portable Cordless Air Compressor with Li-ion Battery, Digital Pressure Gauge, LED Light, Auto Shut-Off - 3pcs Air Nozzles & 12V Car Adapter by Paul Wilson

Very simple product. The plastic seems light and cheap, but that doesn't stop it from working. I opened it and use it without looking at the instructions. Inflated Dodge Caravan tires to 36psi. Inflated my son's bike tires from 0psi to 36psi in less than 30 seconds. Love the glowing screen that gives you tire pressure in psi and the preset worked great. He immediately passed out upon reaching 36 psi. If it lasts, it's worth the money. I will take this with me on all long trips as it can save me some heartache in an emergency!
