Ember Mug 2
The Ember Mug 2 warmer is somewhat different than other options: because the cup itself - rather than the coaster - will help you warm the coffee. Though this mug still comes with a base, it serves as a power adapter rather than a warming point. The mug's battery life is around 1.5 hours, and it accommodates up to 10 ounces.
The Ember Mug 2 mugs and coasters are designed with a clean and minimalist style. They are available in a variety of hues, including stainless steel, copper, gold, white, and black. Apart from its attractive design, this cup warmer provides you with complete control by letting you choose your favorite temperature - between 120 and 145 degrees - via the Ember app. When the desired temperature is attained, the indication light on the bottom of the cup will flash to inform you.
To maintain optimal cleaning methods, this mug should be gently hand-washed. You should not let it get in close contact with strong cleaners, as this might result in irreparable damage.
