Review on DSV Standard Digital Portable Heavy Duty Double Cylinder Air Compressor Tire Inflator, 12V DC 150PSI Air Pump with Auto Shut Off, LED Light & Extension Hose - Perfect for Truck Tires, Bicycle, Dinghy, Balls by William Chavez

DSV Standard Digital Portable Heavy Duty Twin Cylinder Air Compressor Tire inflation looks very well done. On arrival I tested it and found it works as expected. The cable was long enough to comfortably reach all 4 of my tires. The screw attachment to the power rails worked perfectly. It was no problem to check and add air to all 4 tires one by one without additionally stopping the unit. The auto shut off worked as expected. Was easy to use. I really hope I don't have to use it in an emergency, but I'm glad I have it just in case.
