Will it keep coffee hot all day?

It keeps a mug warm for hours at 113°F or 131°F, but it will not bring cold coffee back to hot. Expect drinkable warmth, not steam.

What is the hottest setting?

167°F, the top of three settings. That is below brewing temperature, so it holds heat rather than heating a cold drink quickly.

Does it work with any mug?

Most mugs fit, but the base needs to sit flat on the glass plate. Thin-walled mugs and flat bottoms transfer heat best.

Does it shut off automatically?

No auto shut-off is listed. You turn it off or unplug it when you are done.

Can I use it for candles?

The listing names candle warming as a use, and the glass plate handles the heat. Keep the candle jar flat and within the plate size.

It is one of the cheaper three-setting warmers with a display. If you mainly want to stop microwaving coffee, it is a reasonable buy.

Our take on the 40W Coffee Mug Warmer for Desk with Temperature Display

A corded 40W desk warmer that keeps a mug of coffee or tea warm on a microcrystalline glass heating panel. It has three temperature settings (113°F, 131°F, 167°F) and a temperature display, plus a 59-inch cord and a wood-grain finish option. It is a low-cost entry into a category where many warmers sell for more.

What reviewers say

4.4 / 5126 ratings

Rated 4.4 out of 5 from 126 ratings, buyers generally find it does what a desk warmer should: keeps coffee and tea drinkable for hours at the lower settings. Complaints center on the top setting being weaker than expected and on mugs that do not sit flat.

What people mention

Mug fitMixedFlat-bottomed mugs heat well, while mugs with recessed or uneven bases warm poorly.
SafetyCriticisedReviewers note there is no auto shut-off and the plate stays hot after unplugging.
