Mr. Coffee mug warmer: As I use it, I will update this review. Cord is long (3.5 feet), the actual heating surface is 3 and 3/8 inches diameter, and it's well made and inexpensive. It turns on with a red light on the unit (unlike another brand that has the on/off switch on the AC electric cable). A superb substitute for schlepping my soups in with a thermos every day (hard to clean, extra work at home, etc.)
My goal: warm soup at my desk. I don't want an open flame (e.g. alcohol cook stove), or a very hot 750+ watt cooking element/hot plate. A small Crock pot is hard to eat from and wash--so, I thought this Mr. coffee might be what I want. I don't drink coffee, but could see using it for hot cocoa.
The test: I can put a room-temperature full 8 ounce Campbell's Soup--chicken noodle, to be exact--contents in an enamel-coated aluminum 12 ounce cup with lid, and in 30 minutes it's fairly heated and I could eat it, but in one hour, it's nice and toasty and ready to eat. It's hot enough that I cannot touch the bottom of the cup. I was concerned about the honest reviews that said this does not get hot enuogh--but after using daily for a week, it's mighty hot. I certainly cannot touch the warmer surface--it's far too hot. My office is not near a microwave, and this is a lifesaver for me. I may try canned stews next. I adore eating at my desk. A fellow office mate actually warms water--not to boiling, but very hot--over and hour and then dumps it from the cups into camping meal bags (cook in bag types, like Mountain house) and eats well every day. Sure, if someone had a microwave it's faster, but why challenge the entire office for microwave time in the grody kitchen room when you can set this out an 11AM and be eating well by noon.
Here's the exact cup I use, which fits the Mr Coffee well.
Coleman 12 Ounce Enamelware Coffee Mug (Blue)
Tips: The cup makes a big difference. I use an enamel Coleman aluminum cup, which holds one soup can well (not too close to the top), and conducts heat exquisitely. I have no clue is a hard and thick ceramic coffee mug would work. Also, I put a lid on the cup to hold heat, and so I don't get paperclips and junk in there while it "cooks". Lids reduce heating time by 18% (according to camping websites). I use a simple ceramic drink coaster that I had at home for my lid--any nonflammable lid would work. The lid helps. Also, the Coleman mug that I use is flat bottomed, thus using the entire heating element successfully. A curved bottom mug may not heat as well.
P.S> Okay, I just did Campbell's Vegetable Beef soup in it today, thick and I added no water, and it took about 1.5 hours to get fully hot. Still worked great, but clearly the thicker the soup, the longer the heating time. Also, the heating is most intense at the bottom of the mug or cup, so (1) stirring helps, and (2) a tall style ceramic mug or cup would not be as good as a squat one.
I bought a second one for home since I liked the first one so very much, and to test if the first one was a fluke and just extra hot or something. Guess what, no fluke. The first and second are equally as hot.
Postcript: just for kicks, I put tap water at room temperature in the blue Coleman cup for 60 minutes on the Mr Coffee warmer, and I couldn't even stick my finger in it at all. It was hot! Not boiling, for sure, but clearly hot. I wouldn't want it that hot to drink or to eat. And, so, I added an ice tea bag and took it off the Mr Coffee and drank tea. PLenty hot! Lovely! Bon appetite!

Trusted brand. Sadly it was already chipped.
I had a Mr Coffee warmer for almost 20 years when it decided the die. I decided to get a replacement that came quickly and works fine. A little disappointed that there was already chipping paint in the warmer plate. It doesn’t interfere with performance. Just wish it had looked NEW.
