This review is from: USB Cup Warmer - USB Coffee Mug Warmer (Personal Computers)
This warmer is useless. I still use it thinking that it might actually do something, but I am saddened daily by the lack of heat it gives off.
The only good thing about it is that it turns on and off as I shut down my computer so I never have to worry about leaving it on. (but in reality it doesnt heat up all that much anyways, so who cares if I leave it on!)

Do you know if it would keep coffee warm(er) if it were plugged into a USB 3.0 port?
I can't find any that are made for 3.0.
