Whether you're outdoors hiking or sitting in your cube at work, the Cauldryn Fyre Mug is a great companion. The mug is battery powered an can keep 16 ounces of your beverage at an exact temperature all day long, or even boil water.
If the ability to boil water in a battery powered mug isn't enough, you can also charge your devices from the base of the mug. The mug itself is made from stainless steel and double walled, which helps to keep the cold drinks cold and the hot drinks hot. Not only that, but it has two spouts: one for sipping and one for pouring.
