Review on 🚗 EAUSPL Auto Portable Air Compressor Tire Inflator: Digital Pump for Car Tires, Truck, Bicycle, RV & More by Larry Blanco

The product inflated my tires, which is its primary purpose. However, it had two downsides that combined for me: 1. It only worked when connected to my wife's car, not mine. (I checked twice and all of our other devices work fine on both. Both have 12V outlets and same age batteries.) 2. When I compared the other two analog gauges to their PSI readings, they were at least 3 PSI higher . If it was a constant difference I could just explain it and that would be fine, but the difference was variable. It was least before inflation and worst (5-7 psi more) when I finished inflating before turning it off. This rendered the auto-shutoff feature useless, but more importantly, meant I had to over-inflate them to their readings and then depressurize them with my analog gauges to get proper inflation. I am returning this product.
