Do you want to know how much electricity a device consumes? You can with the Allocacoc PowerCube Extended Monitor, which shows the energy consumption in the form of a car speedometer. So you can quickly and easily see the consumption and the costs. The consumption is displayed to four decimal places, so that you can also measure devices with low consumption. The Monitor shows the total consumption and you can always reset the counter to set a new consumption period. The On/Off button on the display can be used to turn a connected device on or off.
