electrical calculation please

We are looking at a portable dehumidifier.

It apparently runs off a/c via a d/c adapter.

specs says it draws 20w DC and is " energy efficient "

How much of and energy hog will it actually be?

I think I got all of that correct.

Thanks,

Think of it as the equivalent of running a 30 W electric lightbulb 24 hours a day. That will be a close approximation.

Sorry if not clear. I'm trying to figure how much power the unit would use if plugged into a/c at home. In other words, how much affect on my electric bill.

Don't plan on using it while camping

That would be 1.66 amps if thats what your asking.

20w/12.1V (50% SOC)*24hrs = 40 Ah. The typical 2 GCs will have 110Ah to 50% SOC. So it will consume 40/110 = 36% of the battery in a day. Part of that will be the conversion loss to AC.
