This sturdy, stainless-steel, self-heating coffee mug quickly warms your drink to your chosen temperature and automatically turns off when empty. The LED indicator light ensures that you always know your mug’s temperature, and it offers up to 2 hours of heating or all day when placed on the charging coaster!

Hot coffee & tea drinkers love this mug!

Working in management causes me to get pulled from my desk numerous times a day. Previously I would have to warm up my coffee multiple times a day leaving it taste bad and have to purchase or make new coffee but not anymore. I love the multiple temp settings as well. It heats up quickly and does the trick!!


Easy to use and works amazingly. It keeps my tea at the perfect temperature right by my bedside. I always drink a cup of tea before bed and having this nearby helps so I don’t have to walk to the kitchen!

    I have this mug as well as an ember mug. I don’t notice much of a difference in the functionality. It’s definitely worth the savings to get the one from walmart.
