Overview
The COSORI CO294-CW is a digital mug warmer with a stainless steel heating plate adjustable from 77 to 194 degrees Fahrenheit in 1 degree steps. A pressure sensor requires a cup of at least 10.4 ounces before it will heat, and it shuts off automatically after 8 hours.
- 304 stainless steel heating plate
- Touch controls with LCD digital display
- Pressure sensor requires 10.4 oz minimum cup weight
- Fahrenheit and Celsius display options
Who it's for
Good for desk workers who nurse a cup over an hour and want it to stay drinkably warm rather than go cold. Not for anyone who wants near boiling reheating, or who mostly uses light, oddly shaped, or non flat-bottomed mugs.
What buyers say
From Amazon customer reviews.
Several reviewers rate this above other warmers they have tried, citing the wide temperature range and digital display. The recurring complaints are the pressure sensor being finicky about flat, heavy cups and one reviewer describing slow heating on the highest setting that left coffee lukewarm.

Questions about the Cosori CO294-CW
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".

Can the COSORI CO294-CW boil my coffee?
No, Cosori states it is built to keep beverages warm, not to cook or reheat them to boiling.
Does the COSORI mug warmer shut off by itself?
Yes, it automatically shuts off after 8 hours of activity, and the pressure sensor also cuts heat if the cup gets too light.
