Review on ICARMAINT Mini Tire Inflator - Portable Air Compressor with 3000mAh Lithium Battery, Digital Gauge LCD Display, LED Light, 140 PSI - 110V AC/12V DC Air Pump for Car, Motorcycle, and Bike by Tony Nicholas

Beauty. I don't know about internal components but all accessories and bells and whistles are of very good quality and design. Extremely flexible power options (wall mount, car cigarette lighter, battery) but must use a USB port. Even old people can see the display (backlit) well, but the buttons are very small. Very easy to understand and use. I haven't tested the maximum print per square inch, and while it's a bit slow, it's still a perfectly adequate speed. The included light (constant, slow and fast flash), properly placed, is very convenient. Two separate multi-port air hoses offer flexibility of use, but it would be nice if they all fit in the unit's storage compartment. All in all a very good product.
