Specifications:QC3.0 and PDOutput Ports: QC3.0 + Type-C PDMax Output: 60W(22.5W+45W)Output Voltage: DC 5V/4.5A, 9V/2.5A, 12V/1.875ADual USB QC3.0Output Ports: Dual QC3.0Max Output: 36W(18W each)Output Voltage: DC 5V/4.5A, 9V/2.5A, 12V/1.875As:Material: nput voltage: 12V-24VWiring instructions: ''+''is connected to the positive pole; ''-''is connected to negative pole.Operating temperature: -40℃-80℃Application: Mobile phone tablet charging, car charger.Product features: flame resistance, high temperature resistance, corrosion resistance, bility and deformation resistance.Description:1: This is a ligent fast charger, with voltage display, high voltage warning, it can display charging rate, there is a switch that can freely switch the mode of display and turn on/off the power.2: Pre the switch lightly to turn on the power, it can display the real-time voltage after the full-screen lights up for 2 seconds, and then pre the on once again to switch to the red power indicator. Both display modes can be freely switched by the on, Pre and hold the switch for two seconds to turn off the power of the device. After turning off the power, it means that the device has cut off the power input and then achieve the the effect of saving electricity.3: When the input voltage exceeds 14.6V, the red indicator light is on (warning function, it indicates that the input voltage is too high)4: When the power is turned on and the USB charging is performed, the flowing of color screen indicates that it is in charging; it will reflect the speed of charging according to the flowing rate of color screen . When the mobile phone is fully charged, it will light up on the full screen. Two minutes later, It will display the real-time voltage again . The display mode can be switched to a separate red indicator light by preing the switch lightly. Pre and hold the switch for two seconds to turn off the power of the device.5.Multi-purposes: supply power for cellphone, tablet PC, and other USB-devices,Wide Application: cars, motorcycles, ATVs, SUVs, UTVs, Boats, etc6.Pre on once,turn on power or turn off the ,pre on to turn off power.
