<p>A combined power supply and charging device has a 110 volt power input supply, a casing 3 and cable strain devices 7 and 24. A printed circuit board 4 transforms the 110 volt input voltage to that suitable to charge mobile devices such as phones, computers etc from a USB or mini USB port 2. The device also continues to supply an output cable 23 at 110 volts irrespective of the status of the charging port 2 thereby allowing a 110 volt power tool to be used at the same time as a device is being charged from the USB port.</p> |
