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 Darrell Beecher

The inflator turned out to be quite good despite a few minor flaws. Pros: The battery lasts a long time, the air hose is not too short, the quick-release arm is convenient, the metal body is solid and does not overheat, the motor is not too noisy, the airflow is good. Bad: 2 psi gauge reading too high at high inflation pressure. I run my road bike tires at 100psi. If I set my target pressure to 100psi, the inflator will reach and stop at 100psi with no problem. However, if I quickly disconnect the air hose and plug in a known-accurate pressure gauge, the pressure in each tire only reads 98psi. So I need to set the target pressure on the inflator to 102psi to compensate for this. Likewise, the battery level indicator is not accurate. It shows two bars or about half of the remaining capacity, although the battery is almost empty and needs to be recharged. A small issue is that the display is on the end of the device, not on the side. As a result, it can be difficult to see the current pressure while the inflator is running. All in all, this is a good air blower.
