The invention concerns a handheld power generator for generating electrical power for a consumer device, the generator comprising a main casing housing an input gear for driving an alternator via at least one intermediate gear so as to provide a step-up drive ratio in the range of 10:50; the input gear, the or each intermediate gear, and the rotor of the alternator all having their rotational axes perpendicular to the base of the main casing so that the gears and rotor rotate parallel to the plane of the base; a rectifier circuit for rectifying the alternator output; means for mounting a storage device for storing the output of the alternator, a control circuit for modifying the rectifier output to a voltage/current appropriate for the consumer device, and wherein the input gear is connected to a drive member rotatable by manual action to rotate the input gear in turn, the axis of the drive member being parallel to the respective axes of the input gear, the or each intermediate gear and the rotor with all the axes lying in a single straight line.
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 power source that is powered by a user to generate electrical energy includes a generator assembly and a fluid source. The generator assembly includes a rotor, a stator, and a fluid driven motor that is coupled to the rotor. Movement of the rotor relative to the stator results in the generation of electrical energy. The fluid source is manually powered by the user to direct pressurized fluid to the fluid driven motor to move the rotor relative to the stator. The fluid source can include a first fluid pump that is powered by the user to generate the pressurized fluid and a second fluid pump that is powered by the user to generate the pressurized fluid. One or both of the fluid pumps can include a fluid bellows that is powered by the user to generate the pressurized fluid. Alternatively, one or both of the fluid pumps can include a cylinder and a piston that is moved within the cylinder by the user to generate the pressurized fluid.
Enhanced internal electrical generators are provided which include pole pieces that form air gaps flanked with conductive wire coils. Rotatable armatures supporting permanent magnets are arranged to swing or revolve relative to the air gaps such that the magnetic flux thereof is intersected by the wire coils to generate electrical voltage and current therein. These generators may be incorporated within the housing of many portable devices such as cell phones to self generate electrical current useful for operating the device or recharging its batteries or other component that stores the generated electrical energy.
A power generation and/or storage device utilizes human motion inputs or other power sources (i.e. hydraulics, pneumatics or explosive gases) to create mechanical kinetic energy that is stored (preferably in springs) and later released on demand to rotate a generator to produce electricity.
