I bought this to keep my tea warm I figured I could use it on the cup but actually decided to try it on the pot I have a small 24oz pot and I sip on tea all day and it stays quite hot to where I have to let it cool a bit before I can drink it hot.

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.

We've been looking for a cup-warmer that would actually work...the usb-powered type just didn't have enough power, so we returned them to the local store. What really won this particular model is the fact that someone wrote in their review of this product, "...a drop of water on it sizzles." So we gave it a try; sure enough, a drop of water on it sizzles, the coffee stays warm, and we're happy we got it. It works best with flat-bottomed glass/ ceramic cups, but it will also do something for cups/ mugs that have a ridge around the bottom edge. It will work for an 8- to 14-oz. mug, but it works best with the 8-oz.
All that being said, here are a couple of satisfied customers who recommend the product we just acquired.

This product is perfect. It does exactly what it claims to do...keeps your beverage warm. It won't be boiling hot, but it will be at a drinkable temperature until you are done. The chord is long enough and gives a decent range of use. I like to sip the same cup of coffee for hours while I am working, reading or studying and now I never have to microwave it again. I have noticed that it doesn't do as good of a job when the mug is full, but the end of the cup will be quite hot. Well worth the price.

I was wary about getting this as I kept seeing people say that it only keeps things lukewarm and I prefer my coffee/tea just shy of scalding. However, this product is my new best friend. As long as you start with a cup of something HOT it will stay that way - especially when your drink gets near the bottom. Sometimes if i start with a cup that isn't pipping hot, I just put an old CD case over the top and it will heat up a little more , but its not as good as when you start with something hot. Also, I found if you turn it right before you go fix your coffee, its starts keeping the heat quicker/better. All in all, great product when used as it was created for - maintaining heat, not as a hot plate.

I'll start with some specs since Amazon isn't always good at providing them. The cord length is about 68 inches. The flat surface for the mug is 3 5/16". The switch and indicator are on the base (not the cord). The watt rating listed on the warmer is 17 watts, although my Kill-a-watt meter shows it drawing 12-14 watts, depending on the line voltage. There are less expensive units for sale here, but I chose the Mr. Coffee unit because of the longer cord length and the switch and indicator on the warmer rather than the cord like some models. (If you have to use an extension cord, you won't save much over cheaper models.) Starting with a fresh hot cup of coffee, I found it maintained a good drinking temperature, getting slightly hotter as the volume decreased in the cup. I think the price is good considering the quality and construction of the product. Recommended. I see no cons at this point, except that the underside does get a bit hot, as other reviewers have noted. I put a 4 1/4" floor tile under mine to protect my desk.

I have this for almost a year I believe, and so far so good! I don't use it everyday, but maybe once a week, when I'm so busy I can't drink my coffee or tea right away... it keeps them warm, not very hot, specially if your cup is full! it makes the contents at the bottom warmer than top, but I don't mind... and you should just be careful don't put your cup on your lap soon after you have picked it up from this warmer, or you mark yourself a round circle on the lap!

I love this product!! We started with one, two years ago and now we have three!!! All work fabulously. They keep our coffee/espresso deliciously warm while we read, listen to music, work on the computer, swing on the porch outside (we plug in an extension cord and power strip) etc. My husband is a real coffee S N O B and this is the best thing invented since fresh roasted beans. Highly recommend.
By Alexandria Buchholz
I was expecting this to keep my coffee and other drinks warm BUT it keeps it hot! I have to blow on my coffee or hot chocolate before I take a drink. I can walk away and come back an hour later and it is still hot! I love this thing! I'm sooooo glad I bought this!

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!
