So can I with this carry-on. You do some laundry in the sink, have it done at the hotel, and/or find a local laundromat to do it for you or you do it there.

I don't need to worry myself with charging my luggage to juice my mobile technology. I carry a small battery charger in my purse that weighs a mere 4.8 oz that can charge both of my iPhones and my iPad mini 4. This is in addition to the mophie battery case on my phones. So I really don't to waste money on luggage doing the same.
