Gives the voltage, current, power, consumption, cos phi and even the cost spent. The screen is small (and there are many things so it is written small), it requires 3 LR44 batteries (included but the device can operate without batteries - they are only necessary if one wants to calculate the cost of consumption: the price of KWh memory and clock) and you must use an extension cable when the wall socket is not easily accessible for reading. But for the price! In normal use, I use it as the display of power and consumption.
