Using the battery and the capacitor are examples in the application of electricity. These 2 storage devices are used in all types of applications where stored electricity is needed. The common use is to have the electricity storage device dispense its stored electricity for use in the operation of various types of electric equipment, electric vehicles and other electronic devices as a means of powering them. The powering of these different types of devices has been limited to the storage capacity of the storage device. The difficulty in these electricity storage devices are that once they have been depleted, they have to be recharged. The recharging time has created great periods of which these electric devices have to be taken out of service and cannot be used.

A voltage converter converts the received voltage from the adapter when the first control switch is closed. An output interface provides a voltage of the adapter to an electronic device. Some output ports connected to the voltage converter to provide a converted voltage of the voltage converter to electronic devices connected to the output ports.09-29-2011
20100315045WIRELESS POWER TRANSMISSION SYSTEM - The wireless power transmission is a system for providing wireless charging and/or primary power to electronic/electrical devices via microwave energy. The microwave energy is focused to a location in response to receiving a beacon signal from a beacon device by a power transmitter having one or more adaptively-phased microwave array emitters. Rectennas within the device to be charged receive and rectify the microwave energy and use it for battery charging and/or for primary power.12-16-2010
