FAQs
Do mug warmers work with any cup?
Most plate warmers work with flat-bottom mugs. Smart mugs like Ember use their own cup for consistent heating.
Can I heat other drinks besides coffee?
Yes—tea, cocoa, even soup. Just make sure the container is safe for warming.
Are mug warmers safe to leave on?
Models with auto shut-off are safest. Smart induction warmers only activate when a mug is placed on top.
