Abstract
A power accessory for apportioning electrical current between an electronic device and a rechargeable battery used in connection with the device includes two current limiting circuits. The first current limiting circuit limits the current supplied to the device to the peak current that device may demand. Any remaining current from the first current limiting circuit is passed through the second current limiter to the recharge the battery based on a charging algorithm. When the battery is fully charged, the second current limiting circuit stops providing current to the battery.
