What is the surface temperature?

The surface temperature of the plate fluctuates from 210F-247F, measured with an IR thermometer. Note that this doesn't mean will keep your coffee that hot because your coffee & mug are losing heat through the sides and top.

What is the measurement of the heated plate only? Looking for a warmer for a large cup. Thx!

3.25 inches. A 3.5 inch diameter coffee cup will not touch the heated surface.

How long can you keep this on? Does it get damaged after elongated periods of time?

The longest I have had it on was 12-14 hrs (several times) when I forget to turn off at night. There was no damage to the warmer or surface I had it resting on.

What is the length of the cord on this warmer? I purchased a warmer locally & returned it due to the cord only being 18 inches long.

I bought a tease and the cord is only 24". It does not even reach the floor when sitting on the end table. Would it be safe to plug into a extension cord? It's no good this way.
