Review on 🚗 High-Performance Dual Power Digital Air Compressor: 150PSI Fast Tire Inflator for Car Large Tires with Auto-Off and Tire Pressure Gauge – Portable 26ft Pump for Car RV SUV by Sean Maples

First the battery terminals were missing the cover on the negative terminal. I had to cut off some of the old rubber tubing to securely close the exposed copper clamp. But then I tried setting the gauge as directed and it came out at 6 lbs. Screeching and shaking, and then back to zero. The device is about shaken up, but 6 pounds. does not understand at 80lb. Tires! A better English translation for the directions would also be nice.
