Review on JOYTUTUS Cordless Tire Inflator - 6000mAh Rechargeable High Capacity Battery - Compact & Lightweight Air Compressor with Accurate LCD Display for Car, Bicycle, Balls, and More by Danny Lavimodiere

it is necessary to increase the tire pressure from 70 to 75 pounds on the readings of two manual pressure gauges. The digital pressure gauge on the inflator read 64 pounds, it took ten minutes and a lot of noise to add two pounds of pressure. Loved the compact format, hated the evening bag it came in, squeezing a tiny air hose and 12v cord. into a small cavity below - this is a joke. It's too late to return it, but I wouldn't buy it again. Replaced it with a Slime brand inflator, with the same poor results. But at least his gauge was accurate.
