Please note: the total current of the two output ports is 3.4A, if you want to charge your phone quickly, please do not use two output ports at the same time. ⭐[Convenient Design] - The car phone charger owns cord which will work suitably with your devices. Don't worry about forgetting to carry the USB cable. Please note: our USB car charger is equipped with a Type C cable, which cannot charge phones (like Samsung S7/S6/S5) that charging port is Micro USB.
