???LED Voltage Display??This car charger builts in digital red LED voltage monitor, displays the real-time voltage status of your vehicle battery, prevents problems caused by low voltage. The LED light also makes quick and easy to find USB ports in the dark or at night. ???Faster Than Fast??Designed with official Qualcomm QC 3.0 USB port, whose max single output is 18W. Built-in smart chip will intelligently detect your devices and charging devices at optimal current, charge compatible devices up to 4 times faster than conventional charging, twice as fast as Quick Charge 1.0 and 38% more efficient than QC 2.0. ???Certified Safe Guarantee??Certified by CE & ROHS with Over-charging, Over-current, over-heating and Short Circuit Protection to ensure safety, meanwhile, built-in Smart IC ensures the circuit won’t be burnt out if wrong wiring.
Quick Charge 3.0 Technology Smartphones, tablets and other accessories can be charged much faster, significantly saves you time. Built-in Smart IC, outputs stable current without fluctuation. Red LED Voltage Display LED voltmeter can shows the voltage status of car battery in time, prevent your vehicle from starting hard, off and on intermittently and the headlights not enough bright cause by too low battery voltage, or prevent your vehicle from engine instability or horns stopping working. Contrast blue, red is still visible under strong sunlight.
