An apparatus which provides the ability to charge or power multiple devices from multiple different power sources, and to communicate
electronic data to and from one of the devices. The apparatus utilizes simple construction, requiring no active
electronics, thereby reducing the cost of production and the reliability of the device. The apparatus employs a single
USB connection cable with connectors on both ends and a second power-only cable and connector which is connected to the power wires of the
USB cable and thereby is able to power a second portable device from a single
USB port. USB master provide sufficient power for two average portable devices without additional circuitry. Moreover, restricting the
data path to only one device also eliminates the need for
USB hub circuitry. Finally, greater
end user flexibility is provided by using a USB male connector as the source of the data and power connection, a USB female connector for the output of the data and power connection, and a standard
barrel-type power connector for the power-only output connection. Having two different output connectors ensures that the user will not confuse the two connectors.
