Review on 🚗 GSPSCN 150Psi Portable Digital Car Tire Inflator with Auto Shut-Off & LED Light - Heavy Duty Double Cylinders 12V Air Compressor Pump for Auto, Truck, Car, Bicycles, RV, SUV, Balls (Titanium) by Andrew Webster

1. I've tried inflating my RV tire to 85psi but I need 90psi. After 20 minutes the pressure only reached 87 PSI. It takes 5-6 hours to inflate 6 tires! THIS IS DIRECTLY POWERED FROM THE BATTERY AND NOT FROM A CIGARETTE.2. After 20 minutes I turned off the pump - according to the instructions. After 15 minutes I tried again, the fuse blew. I replaced the fuse and it still doesn't work.3. The insert states that the helpdesk is open 24/7 - NO PHONE NUMBER TO CALL!
