Power inverter consumption?

[DageonYar]

I have parked my trailer at my house, and I have it plugged into my AC (battery is disconnected) in order to power the smoke detector, and some ultra-sonic rodent thingies. Just wondering though, the power inverter seems to be humming quite good, and is warm. Does the inverter use quite a bit of power itself? Wondering if it makes more money sense to just leave it un-powered until I'm ready to use it.

Thank you -

IMO I would just disconnect power all together till you are ready to go. We use Koenders bait stations around the house, garage, quonset and trailer.
