Review on Kensun Portable Air Compressor Pump: Efficient 12V DC & 110V AC Inflator for Car, Bike, Motorcycle, Basketball & More - Swift Performance and Analog Pressure Gauge (AC/DC) by Derrick Milkie

Great little car air pump! (I also bought a cigarette lighter extension and recommend it). This came in handy recently when my dad and I were loading firewood into our trailer and the tires started exploding. I hooked up my new little air pump and inflated all the tires from 20psi to 65psi. It's been a while, but what can you expect from a tiny box? It took 15-20 minutes for one hoop. Full size trailer hoop. Duty cycle was not a problem. I love the beautiful case it comes in. The case offers enough space to store a 12 inch cigarette lighter extension. I also like the AC powered option. I don't know when I'll be using it, but it's better than the battery-powered air pump my friend pulled out of the trunk a few months ago. It was great except it only worked for about 4 minutes before the battery died. This was the inspiration for this purchase. Overall I love this product and have purchased 11 of these for all my company and personal vehicles.
