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 Zachary Spaulding

Seems to be a very good little compressor. The auto-shutoff is easy to set up and use, and I found it very intuitive (you don't need to read the instructions, but if you can't figure it out, they're well-written and easy to understand). The cord is long enough to reach all the tires from the 12v plug in my car and the hose is a manageable length too (about 3 feet). If you need a longer spiral hose, this is included in the scope of delivery. The fitting on the tire valve leaks a bit when tightening and loosening, but seals very well once fitted, which is important. The automatic shut-off inflated the tires to slightly over-inflated (per 1 psi from 32 to 39 psi). It only lasted 5-10 minutes so durability is questionable but if it lasts I'm very happy with it.
