But the best gift of all that I received was the smallest item of them all. Mr Coffee Mug Warmer, take a bow... Truly, this mug warmer* really has changed the quality of my life significantly over the last few weeks. Now, you might read that statement and think, 'wow, your life must really suck for it to be possible for a mug warmer to make it better'. But no, my life doesn't suck. I just really, really like hot tea. You see, I work at home. And I don't have any work colleagues to shoot the s*** with - so, to keep me on my toes, I use caffeine. Lots and lots of caffeine. But, much as I like caffeine (delivered through the medium of tea and, of course, it's more sultry sister, coffee), I get very sad when it goes cold. Indeed, taking a swig of cold tea or coffee is about as pleasant an experience as, say, getting smacked in the face with a wet pair of underpants (we've all been there, right?) Anyway, so I got this mug warmer and I switched it on and, lo and behold, there are no more such unpleasant moments in my life anymore (until someone turns up with a pair of wet underpants anyway). One of the small but incredibly irritating daily occurrences that I had come to think was inescapable has now been resolved! (Yes, things can actually get better!) So now, when I am distracted by a Skype call or any other task and so have to abandon my tea for 20 or 30 minutes, I can now confidently return to it knowing that it will still be piping hot (or very warm at least) and utterly satisfying. In other words, this mug warmer product delivers the goods and then some. The tyranny of cold tea has been defeated. And the misery of having to trudge downstairs to heat it back up in the microwave is no more. (Heck, at this rate I might never need to move from my office chair again - progress, eh?) But seriously, if you want a cheap mug warmer that keeps your drink at approximately the same temperature as you prepared it at, then this warmer will do the job nicely. I leave it on all day (yes, us home workers are total rebels, didn't you know?) and it has paid for itself many, many times over by now. *One thing that I have to say is that, while brilliant, this product is NOT a 'warmer' - i.e. it does not *warm* your drink up at all. Rather, it *maintains* your drink at approximately the same temperature as you prepared it at and for a good length of time. For example, if I prepare a cup of tea (which I am about to go an do, by the way), and put it on the warmer, it'll keep it at the same temperature - with only a very slight loss of heat - for up to an hour and beyond. As a voracious tea drinker, I've never actually let a mug linger long enough to see if there is indeed a point at which it will lose all heat. So surely that's a good sign, no? Bottom line: how can you call yourself a serious fan of hot drinks and not own this product? Shame on you! SHAME! Update (2 weeks later): bonus feature detected! If you are like me in that you tend to spill drinks and in the process your mug tends to drip with coffee a lot, you are going to love this... This mini hot plate warmer will sizzle all drippage away instantly once you place your mug down on it, meaning that you can also avoid any future coffee stains on your table. Then all you need do is wipe the warmer clean once it is turned off / cooled down (unless of course you're like me and you don't care). Score! Review: like all the others I see advertised too - 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. ## Features - 17 watt mug warmer for use with coffee, tea, hot cocoa & more - Easy to tote and take anywhere - Surface easily wipes clean - On/off switch with indicator light - Longer power cord for increased mobility ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000CO89T8 | | Best Sellers Rank | #70,690 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #21 in Tea & Espresso Beverage Warmers | | Brand | Mr. Coffee | | Brand Name | Mr. Coffee | | Capacity | 8 ounces | | Color | Black | | Customer Reviews | 4.2 out of 5 stars 57,915 Reviews | | Global Trade Identification Number | 00072179223504 | | Item Dimensions L x W x H | 8.6"L x 5.2"W x 1.3"H | | Item Type Name | Coffee Mug Warmer | | Item Weight | 0.21 Kilograms | | Manufacturer | Mr. Coffee | | Manufacturer Contact Information | For any technical issues contact Manufacturer | | Manufacturer Part Number | MWBLKPDQ | | Manufacturer Warranty Description | 1-year limited warranty. | | Material | Plastic | | Material Type | Plastic | | Model Number | MWBLKPDQ | | Number of Trays | 1 | | Power Source | hand_powered | | Product Dimensions | 8.6"L x 5.2"W x 1.3"H | | UPC | 072179223504 | | Unit Count | 1.0 Count | | Wattage | 17 watts | ## Product Details - **Brand:** Mr. Coffee - **Color:** Black - **Material:** Plastic - **Power Source:** hand_powered - **Product Dimensions:** 8.6"L x 5.2"W x 1.3"H ## Images ![Mr. Coffee Mug Warmer for Coffee and Tea Portable Cup Warmer for Travel Office Desks and Home Black | Gifts for Teachers - Image 1](https://m.media-amazon.com/images/I/81Ja08WuPUL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What is the surface temperature?** A: The surface temperature of the plate fluctuates from 210F-247F, measured with an IR thermometer. Note that this doesn't mean will keep your coffee that hot because your coffee & mug are losing heat through the sides and top. **Q: What is the measurement of the heated plate only? Looking for a warmer for a large cup. Thx!** A: 3.25 inches. A 3.5 inch diameter coffee cup will not touch the heated surface. **Q: How long can you keep this on? Does it get damaged after elongated periods of time?** A: The longest I have had it on was 12-14 hrs (several times) when I forget to turn off at night. There was no damage to the warmer or surface I had it resting on. **Q: What is the length of the cord on this warmer? I purchased a warmer locally & returned it due to the cord only being 18 inches long.** A: I bought a tease and the cord is only 24". It does not even reach the floor when sitting on the end table. Would it be safe to plug into a extension cord? It's no good this way. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It's the little things in life that make ALL the difference... *by P***E on January 16, 2013* I had a very nice Christmas (thanks for asking!), and I got lots of nice gifts.

(but do NOT use as coaster for cold drinks) *by C***A on June 29, 2025* I own 3 of these (for different rooms in my house) and they work great! Simple to use (you flip the on/off switch) and it keeps my tea to the PERFECT drinkable (not too hot, not too cool) temperature for me. It doesn’t have the fancy features of some of the other options out there (no auto shut-off, no temp selection) but I recently tried another brand that DID have those features and still much prefer this one. The other one’s coolest temp kept my tea too cold and all the others made it too hot so I kept having to turn it on and off. This one I can just leave on the whole time I’m using it to keep something warm and the temp remains consistent until the drink is almost gone. Other reviews ARE correct regarding the paint scratching off the heating plate…one of my 3 warmers has a LOT of scratching after 8 years of use (the others a little) but it doesn’t affect function, just looks. **I’ve only ever had to replace one of these (just this week) and the issue was caused by a very specific scenario so it’s worth warning others: do not put FROZEN drinks on this device (or anything else wet), even when it is off.** I had set a bottle of water that had been partially frozen on top of it (with the device off) because I’d misplaced my normal coaster and didn’t want the condensation on the outside of the bottle to drip onto my nightstand. I started hearing a sizzling sound, as if the warmer was on, and noticed the red light was glowing despite it being in the “off” position. I assume some of that condensation must have dripped down through the on/off switch and caused a short. The device stopped working after that, and this could be a potential safety hazard. But should be avoidable if you just don’t put ice cold drinks or other wet things on it. I can overlook any of the other cons of this device due to how effectively this keeps my drink at the perfect temp compared to other brands, but I took off one star for this issue because it IS a potential safety issue, even if it is only likely to occur during an unintended use-case (since I could see a lot of people not thinking it would be an issue to use it as a coaster while off). Overall it has worked great and unless I find another one that actually heats to the correct temp (so far I haven’t), this is the brand I’ll keep using, regardless of the cons. Since there’s no point in having extra features if a drink warmer doesn’t actually warm my drink properly. This one does. Will update this review if that ever changes. —— **Pros** - It’s straightforward to use. Just an on-off switch. - It’s reliable. I’ve only had to replace one of these 3 I own after 8 years (due to getting water in it). - Doesn’t over-heat the surface it’s on (won’t damage wood) and concerns about mild heating (like if it’s above a desk drawer containing stuff that shouldn’t be heated) can be mitigated by placing it on a tile coaster or something. - The sides of the device don’t get too hot to touch, only the heating plate in the center. - Doesn’t require only flat-bottom mugs. - Doesn’t take up a ton of space compared to some other options while still being big enough for multiple mug sizes (all but my largest/huge mug). - It’s the only one I’ve tried that ACTUALLY keeps my tea the perfect drinkable temperature (warm without burning my tongue). I admit I weighted the pros of this feature heavier in my rating, since regardless of any extra features or other pros and cons, a mug warmer is somewhat pointless if it can’t do this. **Cons** - Paint can scratch off the heating plate but this doesn’t affect function, only looks. - It can make drinks that are almost empty a bit too hot. I turn it off once my mug is at that point. - No auto shut-off or temp control features. - The surface that it’s on does get slightly warm. Not so much that it’s damaged any of the wood surfaces I’ve had it on, but I did notice it melted some Aquaphor in the desk drawer of my nightstand (must have been directly under it) so you may want to place a tile coaster under it if using in this setting. - This device is NOT a good option for someone who wants something that can double as a coaster for an ice cold drink when off (due to the safety risk posed by condensation dripping into the switch), but if you don’t plan to use it for that, it should be fine. ## Frequently Bought Together - Mr. Coffee Mug Warmer for Coffee and Tea Portable Cup Warmer for Travel Office Desks and Home Black Gifts for Teachers - COSORI Coffee Mug Warmer & Mug Set for Desk, Cup Heater, Office & Christmas Gifts, 1°F Precise Temperature Control, Touch Tech & LCD Digital Display (77-194℉), 304 Stainless Steel, Silver/Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/670366-mr-coffee-mug-warmer-for-coffee-and-tea-portable-cup](https://www.desertcart.co.uk/products/670366-mr-coffee-mug-warmer-for-coffee-and-tea-portable-cup) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-11*
