Review on Compact 12V Portable Air Compressor Pump Inflator | Auto, Car & Truck Tire Pressure Gauge up to 150 PSI | Includes 3 High-Flow Nozzles and Adaptors | Ideal Airpump Kit for Motorcycle, Bike, Bicycle, and Ball by Andy Jolley

This will be the most compact high performance pump you can find. With all the reviews that didn't leave positive reviews, most likely they didn't know how the fork works. It's not rocket science, just find one of those portable quick start packs with the blue plug and that's it. The quick leveling and accurate reading make me wish I had this beast a long time ago. I like that it's small. The power cable and air hoses are short, but in between you can reach the valve stem to the battery perfectly.
