1byone car charger is equipped with intelligent technology on all ports to identify each attached device and provide the highest charging power that the devices can adapt to. It features 3 Port 7.2A/36W USB car charger which can charge any 3 tablet or smartphone devices at the same time. The charger has been made out of top-grade aluminum alloy and works as a fast charge chip with a fashionable design. You can use cowling to keep the temperatures low thus ensuring stable working conditions, long life time and a low-temperature charging environment. It will automatically stop charging when there is a danger of overcharging or lower/over voltage to prevent damage to the batteries from overheat, over current, and overcharge. The Smart IC chip intelligently communicates with connected devices to maximize both compatibility and charging speed (up to 2.4 amps).
