So, my sister appears to have sent me a USB hub/coffee warmer device. It's essentially a heated placemat that has a 4-port hub in it.
It's rated at 2.5W, so I was wondering what sort of rate a mug of tea/coffee loses heat. Is the 2.5W output, minus all the inefficiencies of transferring heat going to make a significant difference. It gets pretty warm, but I dunno...
Also... would you guys be concerned about plugging in a device that basically uses a short to generate heat into your motherboard?
yeah.... pure adrenaline life here, tonight....
