Review this product

Share your thoughts with other customers

Customers say

Customers find the mug warmer works well and consider it worth the price. The temperature control receives mixed feedback - while some say it keeps coffee at fresh-brewed temperature, others note it gets too hot. The quality and size receive mixed reviews, with some saying it holds up well while others find it flimsy and too small for big mugs. The scratch resistance is concerning, with customers reporting that the plate coating scratches off very easily, and the paint peeling off is a common issue. The auto shut-off feature is also mixed, with some wishing it had an automatic switch.

OK, I read a number of the reviews posted here before purchasing this mug warmer, and did a little research to check what the power used (wattage) was supposed to be. The manufacturers seem to want to keep this a mystery for some reason -- all of them. There were reports that this Mr Coffee device had the same wattage rating as other similar mug warmers that had decent feedback ratings. So, I decided to try it. The power number mentioned was 17 watts, which sounds about right for a device this size. The watts of power generated is THE most important characteristics of any heat producing device and this Mr Coffee mug warmer seems to live up to the purported 17 Watt rating. They don't put any power or energy information anywhere on the packaging material and there is no information in the small instructions pamphlet either but the bottom off the device says: "120 V 60 Hz 17 W", so, 17 watts it is. Now, if this electrical device consumes around 17 watts, you can assume some of the heat energy is lost to the table and the edges of the plastic housing and if you put your hands around the device, there is some loss there and my desk beneath does get a little warm. So, clearly 17 watts is not going into the cup. But for such a simply made device, like all the others I see advertised too, it appears to generate a majority of the heat energy at the indented area where the cup will sit. And by the way, the heating are where a mug sits is 3-1/4 inches in diameters -- which will accommodate some pretty big mugs. The depressed area where your coffee mug sits gets noticeably warmer than the sides of the device. It is hot but not so hot I can't touch it. I wouldn't want to hold my fingers there for very long but it's not like its glowing red. It's touchable. So, I took it out of the packaging, plugged it in, set a cup of coffee on it, and did a little work -- like maybe twenty minutes. The coffee was a bit cold to start, not even cool, and when I picked the mug up a little later the coffee was warm, the mug was warm.. The mug warmer doesn't heat it to a hot coffee temperature but check it's name -- it isn't supposed to. It "warms" the coffee. As a couple of reviews pointed out, the manufacturers are skirting the boundary of generating enough heat to make it dangerous to be left heating on a desk. You can't have a relatively small, inexpensive plastic device have a red-hot burner on it, not when it's intended use is sitting next to my monitor amidst piles of note and maybe near a textbook or two. If you want really hot coffee, clear a space on your desk and get a true hot plate with which you can also fry bacon. Or get a small stand to hold a microwave. After all that, I was quite pleased with how effective it was in "warming" a drink. If you want it to make your coffee hot hot, you will be disappointed. If you want your coffee to stay warm, it does it's duty.

    I bought this warmer as it was way less expensive than all the others. It works just fine. Will fit almost every size mug, has an easy on-off switch and keeps your coffee/tea, whatever, very, very warm. Depends how much liquid is in your cup, and what temperature your cup is when you put it on the little plate. Will not heat a cup of cold water with a tea bag in it. I left mine on for two days, the coffee was way gone, and, had a hard film in the bottom of the cup. Soaked the cup and the burned coffee dissolved, and my little Mr. Coffee still warms up- for another day. Linda Kesselman
  • Reviewed in the United States on December 14, 2011
    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!

    This mug warmer has lots going for it: Plug it in, turn it on, and set your mug of tea or coffee to keep it warm. It’s a no-brainer to operate and the cord is a good length. I didn’t give it 5 stars because it does not have auto shut-off (and I knew that when I bought it). The higher-tech warmers are too fancy, take up too much space and—most importantly—I want to use MY mug, not be constricted to the one that must be used with theirs. All in all, a great buy at a really appealing price.

    The depressed area where your coffee mug sits gets noticeably warmer than the sides of the device. It is hot but not so hot I can't touch it. I wouldn't want to hold my fingers there for very long but it's not like its glowing red. It's touchable.

    So, I took it out of the packaging, plugged it in, set a cup of coffee on it, and did a little work -- like maybe twenty minutes.

    The coffee was a bit cold to start, not even cool, and when I picked the mug up a little later the coffee was warm, the mug was warm..

    The mug warmer doesn't heat it to a hot coffee temperature but check it's name -- it isn't supposed to. It "warms" the coffee.

    As a couple of reviews pointed out, the manufacturers are skirting the boundary of generating enough heat to make it dangerous to be left heating on a desk. You can't have a relatively small, inexpensive plastic device have a red-hot burner on it, not when it's intended use is sitting next to my monitor amidst piles of note and maybe near a textbook or two.

    If you want really hot coffee, clear a space on your desk and get a true hot plate with which you can also fry bacon. Or get a small stand to hold a microwave. After all that, I was quite pleased with how effective it was in "warming" a drink.

    If you want it to make your coffee hot hot, you will be disappointed. If you want your coffee to stay warm, it does it's duty.

    The warmer works well, however, the coating on the warmer is already flaking off after only 4 days. It heats up quick and keeps my coffee heated so I'm not reheating in microwave multiple time. My usage has been 1 hour each day. The flaking isn't bad but I suspect the rest of the coating will be flaking off. I'm thinking the coating is for pure aesthetics and the warmer will still work without it, but, still after 5 days of what I would consider minimal usage, not what I was expecting. My previous warmer I got at menards for $3 and worked and looked great until I dropped in water. Pros: it works , Cons: coating flakes

    5.0 out of 5 stars Compré hace año y medio. En definitiva un excelente calentador para taza.

    Si buscas un calentador para taza, por mucho esta es la mejor opción, sobre todo si amas tomar café, té o cualquier bebida caliente en general. Tengo casi año y medio, y puedo confirmar que sigue funcionando a la perfección, mantiene caliente mi bebida usando cualquier taza (de cerámica obvio) con un tamaño promedio. Incluso ya se me ha caído 2 o 3 veces del escritorio (claramente no lo recomiendo jajaja) y ni así dejó de funcionar bien. El cable considero es lo suficientemente largo, mide más de metro y medio. El único detalle es que el recubrimiento en la base se pierde con relativa facilidad conforme a su uso pero no afecta en nada, por el precio es aceptable. EXCELENTE CALENTADOR :D
