Keep yourself powered up for work whether it's winter or summer with the USB Cup Warmer, Cooler Holder by Thanko. Just connect your computer or other device's USB port to the cup holder and it will maintain a cool or hot temperature perfect for continuing to enjoy your drink no matter how long that presentation takes you to finish. After all, when it's winter and you're keeping yourself warm with a hot cup of tea, the last thing you want is it to cool down. And likewise, in the summer, you want a drink that stays chilled.
The cup holder uses Peltier thermo-elements to maintain the temperature. Just slip the switch to toggle between the cooling or heating functions. Thanko experimented with their nifty device and found that it kept beverages warm or chilled even after 45 minutes! In fact, there is hardly any noticeable temperature change even after 3 hours!
While it's not large enough to hold a regular mug, it can hold a paper cup or a small can (super popular in Japan as sold in the millions of vending machines), and will prove a dainty addition to your desk and working life!
