You don’t have to settle for coffee that slowly gets colder as the morning wears on. This mug has a battery and heating element built right in, and can maintain the temperature of your choice.
The Cauldryn travel mug is basically an uglier (but significantly cheaper) alternative to the more popular Ember travel mug, but with a few added features. Notably, one setting can actually boil water on the go, which makes it great for camping, and its battery includes a couple of USB ports for charging your phone as well.
It normally sells for between $120-$130, but Prime members can get one for just $90, today only.
