Features: Electric Inflator zhaolong JOYYACHT power type dc type electric charge pump. Voltage 12 (V) pressure 380 (psi) The main application range of the machine is the customized model GP80. of the simple use of professional charging pump: Inflation rate: 500L/min. Maximum pressure: 80KPa. Minimum pressure: 10KPa. Voltage: DC12V Continuous working time: 1H. Power line length: 2.7M. Inflatable tube length: 1.5M. The full automatic electric pump USES 12V dc power supply, the maximum current 20A. Please connect the car battery directly or the electric car battery; Please make sure to adjust the air pressure before inflating, which can be preset by red dial. If you inflate the rubber boat, adjust the pressure value to 25(or the corresponding pressure value), and the charging pressure of the keel is 35. The pressure can be adjusted to 60 if the inflatable floor is inflated. Improper pressure setting can cause fatal damage to rubber dinghy. Please read the instruction carefully Fully automatic inflatable pump can be filled with air, and there is a gap in the interface for pumping air. Please pay attention to the positive and negative poles, and the red is positive. The charging principle of the fully automatic charging pump is to inflate the inflatable boat to 80%(without pressure) with the fan, and then inflate it with the piston until the pressure is set and the air is finished. At the same time the pump will stop working automatically. Easy to carry and easy to carry. includes:1* Pump
