Just plug the Samsung mobile device or tablet to micro-USB/USB-C Fast Charger and, with Qualcomm Fast Charger technology, it charges your smartphone rapidly. Compact design fits in your glove compartment or map pocket when you're not using it. Intelligent IC chip ensure optimal charging and cuts off power supply to the phone when battery is fully charged.
