Oracer

This Oracer 18-watt cup warmer has a one-touch on/off button that is very easy to operate. In addition, it also boasts an automated shut-off after eight hours to avoid product damage. Furthermore, the Oracer mug warmer employs a proprietary coffee cup detecting method, which allows it to enter sleep mode five minutes after you have removed the cup. The beverage's temperature will range between 20°F and 140°F (40°C and 60°C). You do not need to worry about water harm, as this warmer is waterproof.

Even though the tutorials state that you should use flat-bottomed mugs for the greatest results, one customer said that this mug warmer still performs an excellent job of keeping their large cup warm and pleasant as well. Moreover, he said that if you strictly adhere to the cup requirements, it is capable of heating colder liquids, too.

Overall, while a few customers complained about the automatic shut-off failing to operate correctly, most clients we know appeared to be very satisfied with this product.
