In the morning, I’d like to have a cup of hot coffee, so I need the USB cup warmer to keep my coffee warm while working in front of the computer. Perhaps, after my lunch, I’d like to have a can of coke that needs me to have the USB chiller to keep it cold. It’s pretty inconvenient that I have to unplug or plug in another gadget just for the opposite effect. Or else I have to sacrifice another USB port in order to power both the warmer and the chiller, which would add up a little mess on my work desk.
Thanks to Brando, which has taken a step ahead that I think they should have done this much earlier on. So, it’s both a drink warmer and chiller on one. To choose any of the functions, just by a toggle of the switch shown in the picture above. Be sure you know what to do when you have a can of carbonated soft drink in it. Do not accidentally switch to the heating function, which would likely cause it to explode!
