US Patent 10433396 Portable electrical device with integrated charger

A portable electrical device, such as an electrical lighting device, comprises a charging channel configured for directing electrical power from the electrical device to a separate electrical device connected via the charging channel (e.g., a charging port). While the charging port is unused, the electrical device generates outputs (e.g., lighting outputs) at a first output power level (e.g., a first brightness). The electrical device also comprises an onboard controller configured to monitor the charging channel, and upon detecting an electrical device connected via the charging channel, the onboard controller decreases the output power to a second output power level (e.g., a second brightness) to conserve power.
