Coffee drinkers know that in order to fully enjoy a cup of coffee, the coffee's temperature needs to be exactly how you like it for the duration of your drinking experience. If you're tired of constantly reheating your coffee (or tea) in the microwave, the right self-heating, electric coffee mug warmer will change your life. Seriously, once you've tried a warming mug, you're never going to want to drink out of a regular mug again. Not only do warming mugs keep your coffee hot, but they also keep the flavor intact, as opposed to continuously nuking it in the microwave.
There are two types of coffee mug warmers: A standalone warming pad that requires your own mug (ceramic, glass or metal) or a warming pad set that comes with an electric mug. A heating pad is the less expensive option, but it doesn't allow you to control the exact temperature or have any other special features, but you do get to use your favorite coffee mug. Coffee mug warmer sets are higher-end and can sometimes be controlled via the company's app for precise temperature control, auto-off functionality and even wireless charging capabilities. The coffee mug, however, isn't dishwasher-safe.

What to Consider When Purchasing a Warming Mug
Battery Life: If you buy a cup warmer like the Ember that has a charging pad and relies on the battery life to stay heated, you'll want to make sure the rechargeable battery works with your routine. Some mugs stay charged for upwards of an hour and a half and can take over two hours to fully charge. If you drink your coffee slowly or drink more than one cup within that time frame, battery life is something to consider.
Capacity and Size: Capacity refers to the number of ounces a warming mug can hold. However, if you end up going with a warming base and use your own mug, you'll want to make sure that the size of the base can hold your favorite mug. A base is typically pretty small and won't take up too much countertop space but it needs to be large enough to hold an oversized mug, if that's what you use.
Care: When it comes to a coffee mug—especially one that you use daily—it's important for it to be easy to clean. Most warming mugs and pads can be wiped down with a clean damp cloth after use and dried right away. The bottom of the mug has to stay dry or it'll damage the charging saucer.
Special Features: Some electric warming mugs come with special features that others don't offer, like smartphone connectivity, wireless charging, an automatic shut-off function and precise temperature control. If you go with just the warming pad, there won't be any bells and whistles.
When you want your coffee hot, lukewarm doesn't cut it. So, take a look at the best mug warmers of 2022 and say goodbye to reheated coffee.
