device to measure electricity usage

[Want2Go]

Does anyone know of a device we can purchase to add to a home outlet to see how much electricity our RV is using?

My sister-in-law has offered for us to store our RV at her house. She has a regular outlet we can plug in to, if we need to run heater or dehumidifier (if it can be run with that situation). I just would like to know how much we are adding to her bill.

Know its a strange question. She will not randomly take money from us and I just don't want to abuse her kindness.

Thanks for your thoughts.

Not sure if this is what your looking for. I have one to measure the power used when our Escape is plugged in on shore power at home and AC is on. Link is from Amazon & indicates it's no longer available from them, however. But I've seen the device available elsewhere.
