Smart USB Charger with Fast Charging - Portable Phone Charger for iPhone, Android, Samsung - Perfect for Travel, Home, Office & Car Use

The Smart Charger efficiently manages the process of re-charging your light; the first 90% of charging is \"rapid charge\" and the final 10% of charge is trickled. The Smart Charger has an LED that varies between red and green depending on its state of charge. Red = charging Green = charged. When on charge the function button on the light flashes green constantly to indicate that charge is being taken.
