However, if you’re getting ready in the morning or you get distracted easily, it doesn’t take long for your coffee to slowly get freezing cold–and nobody likes that. The great news is that you don’t have to keep drinking cold coffee. We’ve collected a list of some of the most effective mug warmers to keep your cup of coffee warm for as long as possible. A nice mug warmer will make sipping your hot tea or coffee a more enjoyable experience. If you’re a person who likes to slowly sip their coffee as they get ready in the mornings, or if you need a way to keep your tea or coffee warm while working at the office. When enjoying a delicious cup of coffee in the morning, it’s nice to sip it while it’s still warm.

What is Coffee Mug Warmer?

A mug warmer is a small desktop device that works similar to the way electric kettles do. Functionally, a Tea or coffee mug warmer is a tiny hot plate that sits on your desk and heats the bottom of your cup to keep the liquid inside hot. A good mug warmer will keep your drink warm without exacerbating unpleasant flavors via scorching. But it’s important to remember that, due to the inevitable effects of oxidation and the way these drinks break down chemically over time, there’s no way to completely preserve the body and flavor of freshly brewed coffee or tea.

Most coffee mug warmers are electric, allowing you to plug them into a wall socket or a USB port.
First off, because they’re simple yet nifty little tools that won’t only make you feel fancy when you use them, but will also make sipping your coffee a lot more relaxed. And Keeping Our Coffee (and Tea) Hot.

All coffee mug warmers aim to maintain a specific beverage temperature, according to what the company deems ideal for drinking; most of the warmers we researched and tested claimed to target a range between 120 °F and 155 °F (though in practice none could achieve a temperature above 145 °F). In our own testing, we found the ideal range to be between 130 °F and 140 °F. Any colder tasted lukewarm, and any hotter made sipping uncomfortable. Of course, your own preference may differ.

How does it work?

Tea Mug warmers use heating coils in the same way electric kettles do. Once plugged in and switched on (most have an on/off switch on the side), electricity flows to a small heating coil built inside the device. A mug warmer works by using the simple properties of heat transfer and thermal energy. If we look at the temperature on a microscopic scale, a material with higher thermal energy just means the molecules in that material have high kinetic energy and are moving around much faster than molecules in a cooler material.

The molecules in a hot cup of coffee, for instance, are moving faster than the molecules in a cold cup of coffee. As the molecules collide, some of that energy transfers, warming up the cooler molecules and cooling down the hotter molecules in a process known as conduction. When you put your cool hands against a warm cup of coffee or tea, your hands will eventually get warmer because heat is transferring from the cup to your skin. So the mug warmer’s coils transfer heat to the base of the mug warmer, and once you place a cup onto the device, the heat from the base will transfer to the cup and the liquid within.
