Review on 🔋 Efficient AUTOGEN Cordless Tire Inflator: Portable Mini Air Pump with Digital LCD, LED Light, 12V AC Lithium Battery - Ideal for Car, Bicycle Tires & More! by John Clark

Very simple design and easy to use. Simply set the PSI and desired pressure based on your vehicle's recommendations listed in your vehicle. Press the power button and it will inflate the tires according to the given PSI requirement and turn off automatically. I've filled 8 tires on two different cars and haven't encountered a single problem. I let the unit sit for a few minutes between each car to make sure it doesn't overheat. Supplied with cigarette lighter adapter and AC charger. Has a light that acts as a flashlight or emergency light if you need to use the curb at night. I'll update the review if I run into any issues, but so far so good!
