Query: Useful for finding power hungry devices

This meter will record the power usage of whatever is plugged into it. I have used it on kitchen appliances and with the powerstrip for my computer or entertainment center and it gave me a good idea of power usage. It needs to be plugged in somewhere with access if you want to make use of it, so behind a microwave or under a computer desk may not work for you.I would recommend this if you are worried about always on devices using a lot of power.
