It connects to the 12V port on your MICRO-START jump-starter, but also works with our Portable Power Stations or other 12v DC outputs. Extremely compact and easy to take anywhere,this mini air compressor allows you to to inflate your Car, Truck, Dirtbike or Motorcycle Tires no matter where you are. It's great for bicycle tires and other inflatables too, from sports balls to small rafts and more. The Antigravity Tire Inflator has a helpful pressure gauge built-in and features an integrated LED light to aid you in dark places. At a very small 3.5 x 1.5 x 4.25 inches (LxWxH) and weighing only a pound, it's the perfect road accessory to keep in your vehicle or motorcycle saddlebag.
