USB Cup Warmer

It’s no wonder that now, every morning at about 8:30am, I make myself a cup of hot tea. It doesn’t matter if it’s Spring, Summer, Fall or Winter, my day wouldn’t be complete without a cup of tea. The thing is though, I’m a sipper, not gulper. By the time I drink the last drop, my hot tea has turned into cold tea… bleh! So, when Brando sent me the USB Cup Warmer.

The USB Cup Warmer is a black stretchy neoprene 11.5 inch wrap with a 38 inch USB cable extending out of one end. A 2.5 inch cutout to allow for a coffee cup handle is located on one end of the wrap. The idea is that you slide the cup handle through the cutout, then pull the wrap around the cup, where it is held in place with Velcro. In practice, the wrap fit my standard sized mug perfectly snug.

You then plug the USB connector into a free USB 1.1 or 2.0 port on your PC or MAC computer, where it will draw enough power to warm the wrap and the cup that it is enclosing. By the way, it’s a good idea to put the wrap on before you fill the cup up with boiling hot water. Wrestling with the wrap while the cup is full, is a good way to spill hot water on your hand… ouch!

The USB Cup Warmer is a novelty more than anything. Although it will keep your beverage somewhat warmer for a longer period of time, it’s up to you to decide if warm is warm enough.
