Abstract: A portable device charger is disclosed, which is able to charge portable devices whether it is connected to an external power supply or not. The charger connects to household AC power as well as USB DC power, and further has a photovoltaic cell. It manages the input power from these three sources to charge a portable device and/or recharge the charger's battery, by supplementing the input power with battery power if the device demands more power than the input source, and charging the battery with remaining power if the device demands less power than is provided by the input source. The charger turns off the AC/DC converter and draws no power from the AC source if the battery is full and there is no attached device.

Abstract: A portable battery charger with inductive charging has a housing, an output inductive coil beneath the surface of the housing to transmit power to a portable device also having a coil therein, and a battery within the housing connected to the output coil, wherein the output coil operates at the battery voltage and transmits power from the battery to the portable device. The charger may also have an input inductive coil beneath the surface of the housing to receive power from a source, and transmit the power to the battery, and the output coil and the input coil may be the same coil. A method of charging the battery of a portable device comprises the steps of aligning the input coil of a portable device adjacent to with an output coil of a charger using magnets positioned near the respective coils, and inductively charging the device battery without connecting the device to the charger.

Abstract: A portable power system which contains a battery, which is intended for use as a power source for charging the batteries of portable electronics devices or for powering other electrical systems. It contains a USB connection for power input and a myriad of adapters for connecting the power system with the proprietary connectors of portable devices, as well as a screen to output system information to the user. The power system also contains a microcontroller which controls internal systems, input and output current and voltage, such that the power system may operate with any portable device as well as any type of USB port.

Abstract: A portable power and/or memory device is disclosed, which device includes integrated management circuitry enabling on-board management of energy storage, power management, and memory management. In a preferred embodiment, the device of the present invention can store and make available both memory and power, and provides an on-board means for displaying the various memory and/or power parameters associated with the device, using a USB interface to receive power for storage and to communicate between onboard memory and a device to which the portable power and/or memory device is connected.

Abstract: Briefly described, the invention provides a photovoltaic assembly power output utilizing device which partially charges a capacitor assembly. This capacitor assembly is then partially discharged by a DC/DC power converter in different ranges of voltages in which the power output from the photovoltaic assembly peaks for different light intensities.
