Patent ID: 8373391

Claim:
A system for flash charging a portable device with a charging device, the system comprising a portable device and a charging device; wherein the portable device comprises: a first interface; a plurality of power-using components; and a first capacitive power supply configured to deliver current to the power-using components; wherein the charging device comprises: a second capacitive power supply; a first interface engageable with the portable device and configured to couple the second capacitive power supply of the charging device to the first capacitive power supply of the portable device thereby allowing the first capacitive power supply of the portable device to be flash charged by a current directly delivered from the second capacitive power supply of the charging device through the first interface; and a second interface engageable with the portable device and configured to couple to the first capacitive power supply of the portable device, thereby allowing the first capacitive power supply of the portable device to be discharged by a current which flows from the first capacitive power supply of the portable device through the second interface.
