Back in 2021, I found myself curious about the Vsitoo self-heating mug. While I do drink iced coffee, I'm one of those people who can drink hot coffee year-round. And I do mean hot; I don't want lukewarm coffee. I've never enjoyed coffee reheated in the microwave: I like milk (no sugar), and the milk skin on a reheated coffee is unappealing. Was a heated mug the answer?
We've deemed this Vsitoo the best of the best when it comes to self-heating mugs, and for good reason — it keeps your drink heated evenly at your preferred temperature from 86°F to 140°F without a hitch, thanks to the battery built in to the mug. That may seem like the baseline for self-heating mugs or heated coasters, but achieving that feat and avoiding a burned coffee taste isn't easy. Somehow, the Vsitoo smart mug can do both.
The app makes your preferred temp highly customizable, too, letting you adjust degree by degree within its range. Off the charger, the temperature will hold for one and 2 hours. While your mug is in use, you can't use the charging coaster to juice its battery back up, but it will keep the battery life from going any lower, and your drink warm.
This mug does only hold 14 ounces of liquid though, so you likely won't need more than an hour a half to finish your morning coffee.
