New And Improved Eva-Dry E-333 Renewable Mini Dehumidifier

I don't understand where you place it to "recharge". Putting it outside in -5 degrees is not an option. Where have others placed it? Thanks

Does this work on 220-230v without a stepdown transformer?Thanks

I get a lot of moisture around my windows in the winter, would this help if I put it on the window ledge?

I was thinking of putting these inside an air duct to prevent mold. Does the back need to have open access to air?
