Patent attributes
Portable lighting devices, systems and methods are provided. The portable lighting devices may include a light source, a rechargeable battery, a battery charging and control circuitry, a power connector port and a wireless communication circuitry. The battery charging and control circuitry may be configured to control transmission of current from the rechargeable battery to the light source, and transmission of current from the rechargeable battery through the power connector port and onto an external device. The transmission of current to the external device may occur when the rechargeable battery has a charge capacity above a predetermined threshold level and terminates when the charge capacity of the rechargeable battery is at or below the predetermined threshold level. The wireless communication circuitry may be configured to transmit a battery condition information of the rechargeable battery to an external communication device through a wireless link.
