USB foot warmer

Once again, we owe another USB specialty to a Japanese company, this time Thanko.

Introduced in a few weeks handheld mouse pad after that, here is also the foot warmer, so we no longer have to worry about freezing any of our limbs during the winter zimankó. Mammoth-like footwear, which warms our feet separately, requires a USB port, so if you want to keep both your mouse control hands and your feet warm, you already have three less USB ports for traditional devices.
