A mug warmer is a small heated plate that sits on a desk and keeps a filled cup warm between sips. Plates differ in size, wattage, the temperature steps they offer, and whether they switch off on their own after a set time, so those are the details worth comparing.
The six warmers below range from a simple 17 watt plate with an on and off switch to a 50 watt plate with four temperature steps and a 12 hour timer. Sizes, wattage and temperatures come from each product’s listing page. We have not used these warmers ourselves, and heating claims are the makers’ own.

Mug Warmer FAQ
Can it heat a cold drink?
Makers describe these as keeping a hot drink warm, not heating a cold one.
Which ones switch off by themselves?
The KitchekShop, SWEETFULL, VOBAGA and Cafzed list a timer. The BESTINNKITS stops when the mug is lifted. The Mr. Coffee lists only a switch.
The Short Version
For the most heat and a 12 hour timer, the KitchekShop. For a wood look, the SWEETFULL. For a small plate, the VOBAGA. For a plain switch, the Mr. Coffee. For a sensor, the BESTINNKITS. For six steps and a display, the Cafzed.
