Travel mugs are great. They keep your beverage (tea, coffee, hot chocolate) hot during cold winters. Sure, sometimes the beverage is too hot to drink right away and you have to wait for it to cool a bit but eventually it will be comfortable to drink. In really cold weather, it might cool off a little too quickly but if you purchase a good quality travel mug, your hot beverage will stay hot longer.
But if you’re willing to pay $150, consider the Ember Temperature Control Travel Mug. It will keep your drink at the perfect temperature all the time.
Let’s say you pour boiling water in your mug but your preferred drinking temperature is 137ºF (58ºC). Your Ember Travel Mug will cool your drink at a much faster rate than a normal travel mug and keep it at 137ºF (58ºC) until you finish drinking your drink. Just think, you can start drinking your coffee first thing in the morning and if you don’t finish it, it will still be exactly 137ºF when you return to it late in the afternoon!
You’ll have to ensure that you keep the mug in the charging dock. Yes, it is another item to keep plugged in and another battery and system of electronics that you’ll need to eventually figure out how to dispose of in an ecologically safe way, but hey — coffee at the perfect temperature all day long.
