Efest LUC BLU6 OLED Intelligent Charger
The Efest BLU6 OLED Intelligent Charger is the first ever to have the ability to charge six batteries all at once with Bluetooth capability so you can check on the status of your batteries straight from your phone. Each slot has its own LED indicator for battery status notification. If it is flashing, the battery is charging. If it is solid, charging is complete. If it is off completely, there is no charge. This device offers safety protection features such as short-circuit protection, over-voltage protection, over-current protection, and reverse polarity.
