Protective cover with wireless charging feature
First Claim
1. A protective cover for a portable electronic device, the protective cover comprising:
- a protective shell for receiving and at least partially covering the portable electronic device when the portable electronic device is installed in the protective cover, the protective shell having a back surface;
a rechargeable power storage device contained in the protective shell;
an electrical coil proximate the back surface of the protective shell;
electrical circuitry configured to;
transfer first electrical power from the rechargeable power storage device to the installed portable electronic device; and
transfer second electrical power from the rechargeable power storage device to the electrical coil, the electrical coil configured to wirelessly transfer at least a portion of the second electrical power to a second portable electronic device that is not in the protective shell when the second portable electronic device is positioned near the back surface of the protective shell proximate the electrical coil, the wireless transfer of the at least a portion of the second electrical power to the second portable electronic device occurring through electrical induction; and
a visual indicator for indicating at least a status of the wireless transfer of the at least a portion of the second electrical power to the second portable electronic device when the second portable electronic device is positioned near the back surface of the protective shell.

Abstract
A protective cover for a portable electronic device includes a protective shell for receiving and at least partially covering the portable electronic device. The protective cover includes a rechargeable power storage device and an electrical coil proximate a back surface of the shell. The protective cover also includes electrical circuitry configured to transfer first electrical power from the rechargeable power storage device to the installed portable electronic device. The electrical circuitry is also configured to transfer second electrical power from the rechargeable power storage device to the electrical coil. The electrical coil is configured to wirelessly transfer at least a portion of the second electrical power to a second portable electronic device. The protective cover may also include a visual indicator for indicating a status of the wireless transfer of the second electrical power to the second portable electronic device.

16. A protective case for a first portable electronic device having a battery, the protective case comprising:
-
a shell for receiving and at least partially covering the first portable electronic device when the first portable electronic device is in the protective case; an inductive electrical coil proximate a surface of the shell; an electrical connector at an interior surface of the shell, the electrical connector for electrically interconnecting to an electrical interface of the first portable electronic device when the first portable electronic device is in the shell; electrical circuitry including a microprocessor, the electrical circuitry configured to receive electrical power from the battery of the first portable electronic device through the electrical connector when the first portable electronic device is in the protective case, the electrical circuitry and the inductive electrical coil configured to wirelessly transfer at least a portion of the electrical power received from the first portable electronic device to a second portable electronic device positioned outside the protective case and near the inductive electrical coil, the second portable electronic device being a separate device from the first portable electronic device; and a visual indicator for indicating at least a status of the wireless transfer of the at least a portion of the received power to the second portable electronic device when the second portable electronic device positioned outside the protective case near the inductive electrical coil. - View Dependent Claims (17)

18. A case for a portable electronic device, the case comprising:
-
a shell for receiving and at least partially covering the portable electronic device when the portable electronic device is in the shell; a rechargeable battery contained in the shell; an inductive electrical coil contained in the shell, the inductive electrical coil configured for inductive wireless power transfer to an electronic accessory device when the electronic accessory device is positioned proximate the shell; and electrical circuitry adapted to wirelessly transfer first electrical power from at least one of the rechargeable battery contained in the shell and the portable electronic device to the inductive electrical coil for wireless transfer of the first electrical power to the electronic accessory device when the electronic accessory device is positioned proximate the shell, the electrical circuitry adapted to visually indicate a status of the wireless transfer of the first electrical power to the electronic accessory device, the electrical circuitry further adapted to transfer second electrical power from the rechargeable battery of the shell to the portable electronic device when the portable electronic device is in the shell. - View Dependent Claims (19, 20)
