Product Description

"USB Bottle & Cup Cooler & Warmer" is an epoch-making product that can do both by just turning a switch with USB connection to a computer. With USB, even if it can make it warmer, is it possible to make it cooler? It is possible! "USB Bottle & Cup Cooler & Warmer" is an epoch-making product that can do both by just turning a switch with USB connection to a computer. Is it really possible to make and keep it both cool and warm on the voltage of USB? That is because Peltier device is used for the cooking/heating system. Thanks to Peltier device incorporated in the body, cooling and heating system could be realized in lower voltage by switching electrodes, which makes the body smaller than any of others. Changing between warmer and cooker is one touch by just turning the switch. Also turning off the power of USB bottle cooler and warmer, without disconnecting USB with a computer, is possible. Even with there is no additional AC power supply available in your office or home, it can make and keep your drink cool or warm powered by USB from a computer. You can enjoy drinks as you like anytime!

This review is from: USB Bottle & Cup Cooler & Warmer (Electronics)

This product is nice because it is relatively compact and sturdy. It does use quite a bit of USB power, so you will have to plug it directly into your machine and not into a USB hub. But it has a heat and cool function and doesn't make any noise or even feel hot/cool to the touch aside from the plate. It also has a nice, long cord.

My major annoyance, however, is with the heating/cooling plate. The size of my mug is slightly larger than the plate, so it does not do a good job of keeping my drink warm. I can tell that the device itself is working because the plate is warm, but it probably won't warm your cup unless it makes direct contact with it. (ie. the cup has to be flat on the plate). I'm trying a smaller cup this time, hopefully it will work nicely. I haven't tried the cooling function yet, should be interesting.
