Yes! The charging coasters for all Ember mugs are all interchangeable and laterally compatible to each mug, including the new Tumbler! All Ember charging coasters use the same charging technology so you can charge any of our mugs on any of our charging coasters. For example, the Ember Mug (Gen 1 & 2) can be charged on the Travel Mug coaster (Gen 1 & 2) and vice versa.
