To use the Microsoft Kinect with your computer you need the power adapter which you connect with the power-usb-port on the data cable.
In closed rooms you mostly have no problems with the power supply but what do you do in the wild wild nature, where no man had gone before, or in the urban jungle where you also can’t find a power outlet. To handle with these problems we build a Battery-Pack to use the Kinect independent of any power outlet. At first we informed us about the power consumption of the Kinect. The Kinect needs 12 V potential and 1080 mA amperage. We bought 10 rechargeable batteries with 1.2 V potential and 2000 mA/h and connect them in series.
