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?...

agreed. if you have a humidity issue you likely will need to remove at least a few gallons of water/day. the device you mention is likely a peltier device, lucky to remove a cup of water/day.
Go to a big box store and look for a portable compressor driven unit. small ones hold 3-5 gallons have an external drain. Now, they will draw about 1-2A on 120V when running, 1A is about 120Watts, so at $.10/kwh, it will cost about 10-20 cents/day to run it for 8hrs/day.
