Backward-compatible with QC2.0, QC1.0, provide standard charging for non-Quick Charge devices.Samsung AFC(Adaptive Fast Charge) TechnologyAdaptive Fast Charge is suitable for Samsung series mobile phones that AFC supported, 60% faster than ordinary car chargers, more efficiently and more applicable.NOTE:Pls pay attention to the positive and negative terminals when connecting the USB charging socket to the powersupply.The maximum charging current can be reached only when the battery voltage of the car is stable and normal, the device charged is short of power and the suitable cable is used.The charging current is not the only indicator to measure the speed of charging. for example, 5v 2A normal charging, and 9v 2A fast charging, car usb outlet's output power is 10W, 18W. The same is 2A current but the power is very different.Please cover the usb power socket with the cap when not in use to avoid dust and water get inside.colour: blackMaterial: ABSPackage Contents:1 x Dual port socket2 x Terminal2 x Blue insulated connector1 x 23.6 inch copper core red and black wire (60cm)Only the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
