The built-in 12 volt DC inflator is the ultimate inflator for all vehicle tires and recreational inflatables. Three
different sized nozzles are supplied. Each nozzle will clip on the end of the standard tire valve connector located at
the free end of the inflator hose. The inflator nozzles are stored inside the hose hatch. The inflator hose with tire
fitting is stored in a retaining channel between the jumper cable channels on the rear of the unit. The ON/OFF
Switch is located on the back of the Main Unit. The inflator can operate long enough to fill up to 3 average sized
tires before the battery must be recharged.
