Coffee Mug Warmer.  Also warms cocoa, tea, milk, etc.

The warming surface is 3.15" wide (8 cm).

It will warm to two temperature ranges:
The warmer will turn off automatically after being on for 8 hours.  

This is a coffee warmer, not a coffee heater.  Also, do not expect it to keep your coffee super hot.  

It works best with a flat bottom ceramic or glass mug, especially when covered.

Do not use with cups with thick or double bottoms, nor with plastic, paper or styrofoam cups.  

Plugs into a 110V standard wall outlet.

It consumes 18 watts of power.

Brand new; it still has the protective film on the warming surface.
