BATTERY PACK FOR WIRELESSLY CHARGING TWO OR MORE DEVICES
First Claim
1. A rechargeable battery pack for use with a first electronic device having a first wireless charging interface and with a second electronic device having a second wireless charging interface, the rechargeable battery pack comprising:
- a housing;
a rechargeable battery configured for storing electrical power;
a first inductive coil configured for wirelessly transmitting a first portion of the electrical power from the rechargeable battery to the first electronic device through the first wireless charging interface when the first electronic device is in proximity to the first inductive coil, wherein the first portion of the electrical power is transmitted to the first electronic device according to a first wireless charging protocol;
a second inductive coil configured for wirelessly transmitting a second portion of the electrical power from the rechargeable battery to the second electronic device simultaneous to the transmitting of the first portion to the first electronic device, wherein the second electrical power is transmitted through the second wireless charging interface when the second electronic device is in proximity to the second inductive coil, and wherein the second portion is transmitted to the second electronic device according to a second wireless charging protocol that is different than the first wireless charging protocol;
an electrical interface for receiving external electrical power from an external power source for recharging the rechargeable battery; and
electrical circuitry contained in the housing and configured for driving the first inductive coil and the second inductive coil.

Abstract
A rechargeable battery pack includes a housing, one or more rechargeable batteries contained in the housing, a first inductive coil, a second inductive coil, and electrical circuitry. The first inductive coil is configured for inductively transferring first electrical power from the one or more rechargeable batteries to a first electronic device through a first wireless charging interface according to a first charging interface protocol. The second inductive coil is configured for inductively transferring second electrical power from the one or more rechargeable batteries to a second electronic device according to a second charging interface protocol that is different than the first charging interface protocol simultaneous to the transferring of the first electrical power to the first electronic device. The electrical circuitry is configured for driving the first inductive coil and the second inductive coil for inductively transferring the electrical power to the first and the second electronic devices.
