If there’s one thing I can count on in the mornings, it’s that my cup of tea will get cold before I’ve finished drinking it.

While it delivers at maintaining my coffee’s not-too-hot temperature ... A simple platform mug warmer is a low-key hot plate, so it’ll heat up whatever you throw on it (within reason).

or heating plate that plugs into an AC outlet ... You might argue that a coffee mug warmer (you know, those $20 Mr. Coffee things) would accomplish the same goal for a fraction of the price ...
