A Pocket S.H.E.R System unit and appliance with Pocket S.H.E.R System and an audio player which includes a manual power generation circuit, an output interface, and a safety control circuit. The input of the safety control circuit is electrically connected to the output of the manual power generation circuit, and its output is connected to the output interface. The system can provide a stable operating current for pocket-size electric appliances which greatly facilitate users. It features low production cost, simple process, and can serve as an independent power for various kinds of electric appliances. With the application of the Pocket S.H.E.R System to the existing players with audio play function, leads to the appliance with Pocket S.H.E.R System and an audio player. A user can manually charge rechargeable batteries or directly supply stable operating current for such players, which greatly facilitates the use of users, featuring convenient use and environment protection. The additional use of a USB interface and a flashlight facilitates users.

A cord reel box with recharging unit has a housing, a rotating plate, a volute spring, a communication cord, a recharging unit, and a pressing device. The gear mechanism is assembled between the rotating plate and the regenerator. The pressing device is pivotally mounted on one side of the housing. The gear mechanism is assembled between the pressing device and the regenerator. An AC plug is mounted on the housing and electrically connecting with the PCB. The PCB has a transformer mounted thereon, and the communication cord electrically connects with the PCB. The cord reel box can recharge a cell phone via the recharging unit or plug with the AC plug.

The invention provides a manually-powered electrical assembly. In one aspect, the manually-powered electrical assembly can be a light assembly that comprises a light source, an electrical generator, and a manual actuator assembly. The electrical generator is electrically connected to the light source and is operable to provide an electric current to the light source to operate the light source for providing light. The manual actuator assembly is arranged with the electrical generator for selectively manually operating the electrical generator. The manual actuator assembly includes an operator handle movable over a range of travel between a normal position and an operated position, a biasing mechanism for biasing the operator handle to the normal position, and a drive train connected to the operator handle and the electrical generator for rotating the rotor of the electrical generator. The invention is operable to power other electrical devices such as a mobile phone or a fan.

A human power generation system includes a generation module and a generator. The generation module includes two speed-up great sets and a rack. Each speed-up gear set includes a shaft to which a pinion and a gear are coaxially mounted. The pinion of the first gear set engages the rack. The gear of the first gear set engages the pinion of the second gear set. The gear of the second gear set is drivingly coupled to the generator. Thus, by attaching the system to a wearer by a mounting device, the systems continuously operates by the natural activity of the wearer and the rack drives, through the gear sets, the generator to generate electrical power.

An organizer for organizing and storing one or more of adapters provided with rechargeable devices includes an AC power supply to provide access to electricity for the adapters to permit one or more of the adapters to operate simultaneously; a mechanism for storing excess adapter wiring; and a mechanism adapted to permit selectively extension or retraction of the wire of the adapter.
