Benefits of technology

[0009]Embodiments of the present invention relate to using a dedicated charging USB hub-device to charge a portable electronic device using a standard electrical and mechanical interface. This plug-in transformer/hub may be used in conjunction with any notebook or desktop computer and various other USB devices. The travelling user can equip himself with several USB charging cables for his small rechargeable gadgets, which can recharge his cellular phone, or other similar products available for handheld devices. When travelling light, the user need only carry his USB charger cables and his notebook computer. The notebook computer can recharge any or all of his other devices. If a personal area network hub is needed, the user can also use the plug-in transformer/hub. The hub need not be plugged in since the notebook can provide power to each device. If the user happens to be located near a utility power outlet, then the transformer/hub can be plugged into the wall, and the USB recharger cables connected t

Problems solved by technology

However, these devices require a specific recharging unit for each unit being recharged and, when using this system, cannot simultaneously be in communication via the same cable.

Abstract

Embodiments of the present invention relate to an apparatus for supplying power to electronic devices, comprising a housing, an electric power source connector coupled to the housing, an electronic circuit enclosed in the housing and electrically coupled to the power source connector, and a universal serial bus connector coupled to the housing and electrically coupled to the electronic circuit, wherein the connector is capable of supplying electrical power to one or more electronic devices for battery charging. The electronic circuit is capable of controlling the charging of the batteries of more than one device and can be enabled to provide data communication between data devices. The apparatus may receive power from a utility power outlet or from another electronic device through the USB connector.

Description

FIELD OF THE INVENTION[0001]The present invention relates to the field of recharging battery-powered electronic devices.BACKGROUND OF THE INVENTION[0002]As the number of small, portable, electronic devices in daily use have multiplied, so too have the devices used to charge the batteries of these devices. Each new device seems to arrive from the store with a recharging unit, or “brick,” in the sales package.[0003]Many modern portable electronic devices are capable of processing data. There are even complete personal area networks comprised entirely of devices that are solely powered by internal batteries.[0004]Such useful devices are commonly found in use by those travelling in the employment of technology concerns. Engineers in high tech often find themselves working in a hotel room with an array of devices, such as a laptop computer, a printer, a scanner and sometimes a cellular phone, all linked together into a personal area network and connected to the internet. Frequently, the ...
