Multi-mode portable lighting device with novel battery charging unit

A portable lighting system comprising:

• a flashlight, the flashlight comprising
• a housing having a proximal end and a distal end,
• a light source disposed at the proximal end of the housing,
• a rechargeable battery electrically coupled to the light source,
• a battery charging and control circuitry disposed in the housing and operatively coupled to the light source and the rechargeable battery bank, the battery charging and control circuitry coupled to a power connector port for receiving and supplying current, the battery charging and control circuitry configured to control transmission of current from the rechargeable battery bank to the light source, the battery charging and control circuitry further configured to supply current from the rechargeable battery bank through the power connector port and onto an electrically coupled external device when the rechargeable battery bank has a charge capacity above a predetermined threshold level, the predetermined threshold level is set at a value within a range between 5% charge capacity and 30% charge capacity, and
• a wireless communication circuitry operatively coupled with the battery charging and control circuitry, the wireless communication circuitry configured to transmit a battery condition information of the rechargeable battery to an external communication device through a wireless link;
• and
• a software application running on the external communication device, the software application provides the battery condition information of the rechargeable battery pack.

A portable lighting device comprising:

• a housing having a proximal end and a distal end, the housing defining a hollow cavity;
• a light source disposed at the proximal end of the housing;
• a rechargeable battery bank electrically coupled to the light source;
• a power connector port operatively coupled to the rechargeable battery bank and configured to receive current from a power source and supply current to an external device;
• and
• battery charging and control circuitry disposed in the cavity of the housing and operatively coupled to the power connector port and the rechargeable battery bank, the battery charging and control circuitry configured to facilitate transmission of current from the rechargeable battery bank to the light source, the battery charging and control circuitry further configured to facilitate transmission of current from the rechargeable battery bank to the external device when the rechargeable battery bank has a charge capacity above a predetermined threshold level, and to preclude transmission of current when the charge capacity of the rechargeable battery is at or below the predetermined threshold level.
