This is not your average cup warmer. There are plenty of cheap ones around that keep your mug warm but don’t do a whole more. This one by Thanko also holds your drink safe and can cool it. Just connect it to your laptop via USB, and you are set. The cup holder uses Peltier thermo-elements to maintain the temperature. It automatically turns off when temperatures exceeds 90°C. This may be a bit small but works great for paper cups
