How warm does it keep a drink?

It holds a mug at a steady warm temperature rather than bringing it to a boil. Expect a drink to stay pleasantly warm for a long session, not to heat a cold cup quickly.

Which mugs work on it?

The plate is made for cups of any material, so glass, ceramic, and metal mugs all work. Thin-walled mugs warm faster than thick stoneware.

Does it have more than one heat setting?

Yes. A touch icon switches between low and high temperature.

Is it safe to leave on a desk?

The top is tempered glass and the body is ABS plastic, and the design is described as waterproof and anti-leakage. Keep spills away from the cord and unplug it when not in use.

What comes in the box?

One cup heating pad, a power cord, and a white travel plug adapter.

Can it heat a cold cup of coffee?

Only slowly. It is a warmer, not a hot plate, so it is better at holding temperature than raising it.
