[Universal] Suitable for bicycles, cars, motorcycles, tricycles, electric vehicle tires, footballs, basketballs, inflatable boats, air beds, balloons, etc.Take out the lighter plug and insert it directly into the car lighter. Turn on the air pump switch. After the air pump is started, insert the valve at the top of the inflation hose directly into the tire valve. When you hear the sound of tire leakage, it means that the air has circulated and you can tighten the air nozzle to inflate. At this time, the air will no longer leak out.When inflating, the gauge pointer rises as the tire becomes saturated. When the pointer reaches the appropriate tire pressure (general car tire pressure is 223kpa=35PSI), remove the plug and valve, and the work is completed.Please use the professional ball needle, connector and air nozzle equipped with this machine to inflate the ball and other air-demanding equipment.Working voltage:DC 12VMaximum working current:10A (super high power)Maximum air pressure:100PSIFlow:35L\/minPower cord length:285cmContinuous working time:15min[Precautions]1. When using, please start the car engine first to increase power and do not consume the car battery.2. This machine only uses DC (DC12V10A) power supply and cannot use household high-voltage power supply.3. When inflating, please run continuously for 10 minutes, then cool down and rest to extend the life of the motor. The rubber boat can work continuously for 30 minutes after being inflated.4. Generally, when inflating tires, it takes about 3-6 minutes to reach the normal tire pressure of 220KPA. Bigger tires last longer. If the indicator needle rises quickly when you start to inflate, the tire is not yet filled with air. You have to stop working and start over. Otherwise, the instrument and motor will be damaged.Colour:Black & SilverMaterial:ABS+aluminum alloySize:13x8x15x11cmPackage Contents:1set * car air pumpOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
