The Spark Portable Charging Station supplies power to Intelligent Flight Batteries and smart devices wherever you go with an impressive amount of total power. When fully charged, it can charge up to three Spark batteries. Without removing the battery from the aircraft, you can simply place Spark into the station to begin charging, and the Charging Station features two additional charging ports for spare batteries. When charging, it will first charge the battery on the aircraft, and then the two spare batteries in accordance with their power levels from high to low. When connected to an external power source, the Charging Station will charge itself as well. It can also supply power to mobile devices such as smartphones or tablets through the power port.
