Mr.Coffee

Mr. Coffee mug warmer is no doubt one of the most popular items on Amazon (with more than 46,000 ratings), and of course, it is also among the best mug warmers available. This 17-watt cup warmer keeps coffee, tea, and other hot liquids warm for as much as you want. It is lightweight and portable, and the extended power chord adds to the mobility. The on/off button has an LED indication for further convenience.

There were a few worrying concerns about the item on Amazon from customers, however, which centers on potential safety issues. One client said that, though this Mr. Coffee mug warmer maintains an ideal temperature for the coffee, he was unaware the light was on. Hence, he had let the product stay on overnight and melt all the interior content.

Another reviewer, on the other hand, noted that if you read the guidance steps carefully and unplug the gadget after usage, you should have few problems in the long term.
