The best mug warmers we tested

With the best mug warmer within arm’s reach, keeping your favorite hot beverage at the perfect sipping temperature is effortless. Whether you’re on your third cup of coffee in the office, nursing a cold with some herbal tea or curling up with a good book and a cup of hot cocoa on a rainy day, a mug warmer is a simple yet very effective way to keep that hot drink hot for longer. It’s also a great gift for coffee lovers this holiday season.

Currently, there are three different types of mug warmers: warming plates like the Misby Coffee Warmer, self-warming mugs that usually have a built-in rechargeable battery and smart mugs that offer in-depth app support, such as the Ember Mug 2. And every product is different, particularly when it comes to heating performance, safety measures, design, price and even extra features.

We got our hands on 10 of the most popular mug warmers from brands like Ember, Thermacup, NextMug and Mr. Coffee and put them through rigorous testing. After an immeasurable (and probably unhealthy) amount of caffeine, lots of wired early afternoons followed by hard crashes on Uber rides home, and the occasional upset stomach, we found three standouts. All so that the next time things get busy at work or you get too immersed in the story you’re reading, you can rest assured that you have a steaming beverage waiting for you.

Best mug warmer

A much-improved version of the original, the Thermacup V2 Self-Heating Mug elevates the mug warmer scene with its impressive heating performance, long battery life with lid on and affordability, among other things. It’s a winner, in our book.

Best smart mug

The only true smart mug in existence, the Ember Mug 2 offers the convenience of app support so you can customize heating settings, check on battery life and more with ease. We also love its design, especially now that it comes in more fun colors.

Best warming plate

Impressive heating performance and effective auto shut-off features set the Ikago Smart Heated Coffee Mug Warmer above other warming plates. It’s slightly more expensive than its rivals, but a better value than the rest.

Best mug warmer: Thermacup V2 Self-Heating Mug

Michelle Uy/CNN Underscored

Putting a more versatile spin on travel coffee mugs, the Thermacup V2 Self-Heating Mug keeps your coffee warm on the road and at the work desk. Thermacup may not have popularized the concept of a self-warming mug, but it certainly elevated it, offering flexibility, quality and great all-around performance in an affordable package.

There’s a lot we love about the Thermacup. Its heating performance is the fastest and most effective we’ve seen, with our beverages consistently jumping at least 10 degrees Fahrenheit higher in temperature in just 10 minutes and maintaining their target temperature for longer, and that’s with the mug lid-free and off its charging base.

The Ember Mug 2 does beat its battery life by more than 30 minutes without a lid (and its charging time by half an hour), but with the lid on, it’ll last for hours. During our testing, it stayed toasty for three hours and 20 minutes at the 130 degrees Fahrenheit setting without a drop in its heating performance. That’s more than enough time to enjoy your favorite hot beverage at your ideal temperature. Considering the Ember is more expensive and doesn’t include a lid in the box — that’s $15 extra — you can easily see which one is a bigger bang for your buck.

Adding to its value is its bigger capacity. The Thermacup V2’s 12-ounce model is much cheaper than the Ember Mug 2’s 10-ounce model (coming in at $90 and $130 respectively). And if you need a bigger or smaller mug, it comes in 10-ounce and 14-ounce versions, priced at $80 and $100 respectively.

Its lid isn’t spillproof, but we’ve turned this mug upside down (with tepid water inside, of course), and we can confirm that you only run the risk of spilling droplets. Though we certainly would not recommend performing the same experiment with piping-hot liquid inside, rest assured that it’ll keep most of your caffeine inside for consumption. You can fill this up with coffee for your morning commute without worrying about getting scorched, just as long as you remember to close the sealing slider between sips.

It doesn’t have app support, which means it’s technically not a smart mug, but it offers an easy one-button operation. Its single readily accessible button is all you use to turn the mug on and off and to cycle through its five temperature settings (110 degrees Fahrenheit, 120 degrees Fahrenheit, 130 degrees Fahrenheit, 140 degrees Fahrenheit and 150 degrees Fahrenheit). There are two light indicators as well, one for its battery status and the other for its current temperature setting, so you’ll never want for anything in terms of on-the-fly operation.

To keep things safe, it boasts an effective auto-shutoff function and a very responsive motion sensor for waking. When it doesn’t detect liquid inside, it automatically turns the heating element off and goes into standby mode. All you need to do to wake it up is lightly touch it or pour water in.

The Thermacup V2 also feels robust and is made of quality materials, with a six-foot cord that makes it easier to place around the house or your work area. We recommend keeping it secure to minimize falls or hard knocks, however. The one time we accidentally dinged our test unit, a tiny bit of paint came off. Also, the mug is hand-wash only, so please don’t toss it in your dishwasher. In fact, as a general rule, don’t put any self-warming mugs in the dishwasher or microwave oven.

Best smart mug: Ember Mug 2

Michelle Uy/CNN Underscored

Out of all the self-warming mugs and mug warmers we tested, the Ember Mug 2 takes the award for most elegant-looking. Sleek, stylish and compact, with a soft matte finish (excluding the metallic collection styles) that feels nice to the touch, it’s likely the first thing we’d pick up if all our tested models were displayed side-by-side on a shelf. That’s especially true with its new colors, lavender and powder blue, now available.

It doesn’t just get by on looks alone. Its heating performance is excellent, second only to the Thermacup V2. It heats coffee by almost 10 degrees in 10 minutes at a heat setting of 130 degrees. Beverages don’t always make it to the exact target temperature, even after an hour of heating, and do tend to get about 3 to 5 degrees Fahrenheit colder past the one-hour mark, likely due to the lack of a lid in the box. However, the mug performs better than the Thermacup in longevity. Ember rates its battery life at an hour and 50 minutes on the 10-ounce model, but we’ve seen it last 10 minutes longer. Charging that battery to full also only takes two and a half hours, 30 minutes faster than the Thermacup.

It’s just too bad we didn’t have the lid handy so we could gauge its heating performance with one on. Then again, not having a lid included is also big factor here since, in this economy, most people wouldn’t deem it practical to spend $15 more when they’re already paying $130 for a 10-ounce self-warming mug. The 14-ounce model is even pricier at $150.

Without the lid, however, know that the mug isn’t designed to be used on commutes, which somewhat beats the purpose of its built-in battery. If you decide a lid isn’t necessary for your needs, we recommend keeping it on the charging base, giving you all-day heating.

If you have a bigger budget, the Ember Mug 2 is worth the splurge, as it comes with app support. It has a power button at the bottom (as well as a battery and heating light indicator) and works without the app, but you’re limited to the 135 degrees Fahrenheit heat setting. The Ember app expands its functionality, since it lets you set your desired heating temperature with a simple swipe of a slider. The app also offers different heating presets for different types of hot beverages, lets you know how much battery life the mug has left and sends notifications on statuses like empty-cup detection.

Speaking of which, when the mug doesn’t detect any liquid inside, it automatically shuts off after a minute. To wake it up, you just need to pick it up or pour liquid in. Both work like a charm, so there’s no need to worry about overheating.

The Ember Mug 2 is the most expensive of the bunch, but if you want a true smart mug, it’s hard to beat.

Best warming plate: Ikago Smart Heated Coffee Mug Warmer and Mug Set

Michelle Uy/CNN Underscored

Coffee warming plates are often the cheaper mug warmer options, which means they’re the way to go if you’re on a budget. The problem is not many perform as well as the mugs with built-in batteries. We tested six warming plates, and only two truly matched the self-warming mugs in heating performance. Out of those two, it was the Ikago Smart Heated Coffee Mug Warmer that truly impressed us — so much so that we shared the extra test units we had with our colleagues.

To be very fair to the other warming plates we tested, this one is a little more expensive at $70. Still, we think it’s worth the money for two big reasons: its impressive heating performance and its auto-shutoff features.

While the others either struggled to get close to the set heating temperature (we set every single model at 130 degrees Fahrenheit during testing apart from one) or reach that temperature in under 30 minutes, this warmed our beverages up to at least 130 degrees Fahrenheit in just under 20 minutes. That’s with and without the lid covering the included mug. The only mug warmer to rival that heating performance is our current top pick, the Thermacup V2, whose heating efficiency slightly struggled without the lid.

Its auto-shutoff features are also superior to that of its rivals. There’s still the issue of the heating pad being hot enough to mildly burn your skin if you come in contact with it, something most warming plates have in common. However, it automatically shuts off after 15 minutes when it’s not detecting a cup on the pad and after two hours of no activity, minimizing the risk of overheating or a fire breaking out. Both these features work like clockwork after testing them ourselves.

The temperature touch buttons on the LED display also lock after five seconds of no activity, and you’d have to double-tap either button to unlock them, minimizing accidental presses. That’s not too shabby for a mug warmer in this category, especially one that’s very easy to set up and incredibly intuitive to use.

That LED display is another great feature. It sticks out in the front in a small cube, making the mug warmer look space-age retro, and displays real-time temperature, a status bar, the set temperature and an indicator that lets you know whether or not it senses a cup, which is a vital feature, as the device uses dual infrared sensors to detect the presence of a cup. If it’s not sensing one, then it’s likely that you’re using the wrong type of cup. Ikago recommends using ceramic mugs for best results, and we do love the one included in the box and the stirring spoon that comes with it.

Our biggest complaint about the Ikago Smart Heated Coffee Mug Warmer is that it isn’t the most portable. Compared to the others, the warming plate is thicker and bulkier. You would also have to store the mug and its lid separately lest you risk one scratching, cracking or chipping the other. But if you’re planning on keeping this in one spot, that isn’t really a factor.

How we tested

We tested all the models we had in a span of three weeks, using them in our day-to-day routines at home and in the office as well as putting in hours of lab testing. We not only got a feel of how they perform in the real world but took measures for fair and accurate comparisons.

Not only do mug warmers come in many shapes and sizes but they come in several styles, so we had to make little tweaks to our testing process to accommodate those differences. For example, because a couple of mug warmers in our testing pool did not come with a lid included, we tested those that did with and without their lids.

Since warming plates don’t typically have a built-in battery, we didn’t include battery life criteria when judging their overall performance either, especially against the self-heating mug models. While we did pit each one of those warming plates against the self-heating mugs, we only focused on their heating performance, safety measures, ease of use and portability.

We evaluated each mug warmer using the following primary criteria.

  • Heating performance: Looking beyond a mug warmer’s heating effectiveness, we also considered efficiency and speed. After all, one may successfully heat your coffee or tea, but if it takes 30 minutes to an hour to reach your ideal sipping temperature, you might as well make a fresh cup. To gauge each model’s heating performance, we used timers and a waterproof thermometer, measuring how fast each one could heat beverages, how long it could sustain the target temperature and if it even reached that temperature in the first place. We used 130 degrees Fahrenheit as our target temperature because coffee enthusiasts tend to prefer their coffee at 120 degrees Fahrenheit to 140 degrees Fahrenheit and one or two of the models in our testing pool could only heat at that temperature.
  • Battery life: Excluding the warming plates, which do not come with a built-in battery, we measured how long each self-warming mug would last while heating a hot beverage at 130 degrees Fahrenheit. On models that come with a lid, we did that battery test twice: first without the lid on and then again with the lid on — they tend to last longer with the lid improving heat retention, and we wanted to see just how long they could truly last. We also timed how fast each recharged from zero or 5% to 100% and made sure to charge every self-heating mug to full before each battery test.
  • Safety measures: Fire is a concern for folks who haven’t used a mug warmer before, so we made sure to test each model’s auto-shutoff features, paying close attention and even using a timer to see if it worked as promised. We also gauged how effective and useful those auto-shutoff features are, as well as tested any wake functions present.
  • Design: Not to be confused with the aesthetics, we looked at each mug warmer’s build quality and materials, size and capacity, cord length, controls, light indicators and more.
  • Ease of use: Mug warmers are pretty straightforward to use, generally speaking. However, some are more so than others, depending on their initial setup, features, how they implement their different features and how easy they are to clean. We noted all of those in our real-world testing.

For a fair assessment, we also considered the following secondary criteria.

  • Portability: We tested how portable each mug warmer is, based not just on its size and build quality but on its design and individual parts. Some mug warmers, for example, feature a ceramic mug with a cover that’s designed to just sit on top of the mug. To test portability, we spent several office days transporting each mug warmer to and from the office, noting how easy it was to carry in our bags and how they survived the commute.
  • Additional features: Outside of valuable functions like auto-shutoff and an LED display, mug warmers typically don’t have extra features. Occasionally, though, you will come across one that boasts phone-charging capabilities or app support. We tested these features on the models that had them, gauging how well they worked and if they add value.
  • Aesthetics: While it is a matter of preference, we still looked at how each mug warmer looks, noting their appearance, coating, style and more.
  • Price: After assessing each mug warmer on all the criteria we mentioned above, we then weighed its overall performance against its price tag so we could decide fairly whether or not it’s a great value to consumers. We also compared its value against the rest of the models in our product pool before making our recommendations.

How to choose the right mug warmer

Choosing the right mug warmer for you isn’t as straightforward as you may think.

As we have explained, there are at least three different types of mug warmers. The most common one is a warming plate, which is similar to a hot plate except its heating element doesn’t get as hot. Warming plates may or may not come with a mug in the box. The second type, which is getting more and more common, is the self-warming or self-heating mug. It typically comes with a built-in rechargeable battery and a charging base, meaning that it can keep coffee hot without being tethered to the base. Finally, there’s the smart mug, which is the rarest. In fact, we’ve only seen one available in the US: the Ember Mug. This type boasts app support so you can conveniently control and change its settings from your phone.

It’s also very surprising that no two mug warmers are even close to being alike, even ones of the same type. The six warming plates we tested, for example, are vastly different in design, the type of heating element they use and their features.

Know your needs and preferences before choosing

This means that before you go on Amazon, scan through reviews and hit buy, you should figure out your particular mug-warming needs and preferences. For example, do you need one that you can use during commutes as well as in the office, or do you just need one within reach at your desk? If it’s the former, how long do you need it to keep your drink at the perfect temperature before it needs to be charged?

Digging further, do you need one that gives you different heat settings, or do you want something simple as long it’s able to heat your drink at your preferred temperature? Do you need something that takes less work to use? Some mug warmers only turn on when they detect a mug and automatically turn off as soon as you remove the mug. Others, you have to remember to turn off yourself after every use.

These are just some of the pertinent questions you should ask yourself before looking at all the options available.

Heating performance is vital

Not only should you consider the different heating features available on a mug warmer but you need to look at how effective its heating performance is and how fast it takes to get to the target temperature.

You should also know that just because you’ve set the mug warmer to a certain temperature, it doesn’t mean that it’ll actually heat your drink to that temperature. Of all the models we tested, there were only a handful that managed to heat beverages to the temperature we set. What’s more, some are much slower to heat drinks than others.

Choose one with effective auto-shutoff and safety features

Because mug warmers typically have a maximum heat setting of 150 degrees Fahrenheit to 200 degrees Fahrenheit, they don’t pose as big of a fire hazard. Remember that paper burns at 451 degrees Fahrenheit, polypropylene and other clothing fibers ignite at 350 degrees Fahrenheit and wood starts to burn at around 320 degrees Fahrenheit. However, exposing an object to heat over time, even at low temperatures, can still cause a fire, which is why you should choose a mug warmer that comes with auto-shutoff and other safety features.

Most mug warmers have some level of automatic shut-off, so it’s just a matter of choosing one with shut-off features that actually work, and work best for you.

Budget doesn’t mean better value

There are a lot of cheap, under-$25 mug warmers on the market. A quick search on Amazon will yield at least a hundred options from both popular and unknown brands. However, we don’t recommend just choosing the highest-rated one that’s also the least expensive.

We found that the cheapest models in our testing pool aren’t as effective at heating as the ones that are over $50. Bear in mind, though, that just because a mug warmer is expensive, it doesn’t mean it’s going to deliver the best heating performance. We recommend reading our reviews of all the models we tested to get a better idea of which one would work best for you.

Other mug warmers we tested

Easy to use and stylish, the Nextmug Self-Heating Coffee Mug is one of the most popular self-warming mugs available. It comes with light indicators for battery life, heat setting and real-time temperature, and it delivers great heating performance.

Starting with its 14-ounce drink capacity and a stylish matte ceramic finish, the Nextmug Self-Heating Coffee Mug boasts several features that make it easy to recommend. We love its spacious handle, 6-foot-long cable and the three light indicators that let you quickly check battery life, current heat setting and real-time temperature. We also appreciate that it only comes with a single button, which functions as both the power and the heat setting controls, making it effortless to use.

Although it doesn’t have a sealing slider, it does come with a lid, which allows it to work as a travel mug; you just have to be careful not to tip it or slosh around that hot liquid inside. The lid also improves its heating performance considerably, heating beverages to 20 degrees higher at its warm (130 degrees Fahrenheit) setting in only 10 minutes, hitting that target 130 degrees Fahrenheit within 15 minutes and maintaining it for at least an hour.

Sadly, without the lid, the Nextmug Self-Heating Coffee Mug isn’t as effective, struggling to get past 120 degrees Fahrenheit even after an hour. For reference, both the Thermacup V2 and the Ember Mug 2 managed to get to 130 degrees Fahrenheit without the aid of a lid. That’s disappointing, especially considering the Nextmug’s $130 price tag.

That’s not all. This self-warming mug also underperforms in battery life. While Nextmug promises just over two hours without the lid and close to five hours with the lid on warm, it only lasted us two hours and 55 minutes, and a little over an hour, with and without the lid on, respectively. It also takes too long to charge, taking three hours and 10 minutes to reach 100%.

The Ohom Ui 3 Self-Heating Mug Set is the warming plate to get if you’re looking for something elegant yet functional. It also moonlights as a wireless phone charger, giving you two devices in one svelte pad.

“Meticulously handcrafted by skilled ceramic artisans,” according to Ohom’s website, the Ohom Ui 3 Self-Heating Mug Set looks more like it belongs in a Chinese art show or on display on your hallway console table. From its mug to its charging pad, this mug warmer boasts elegant curves, giving it a classier, nature-inspired look.

More of a warming plate than a self-warming mug, what’s unique about it is that it utilizes electromagnetic energy to warm beverages in its included mug. Although that does mean that you cannot use any other mug on this pad other than another Ohom Ui mug, you also get to enjoy the added feature of wireless phone and earbuds charging. And its heating performance is among the best of the warming plates we tested, with only the Ikago Smart Heated Coffee Mug Warmer surpassing it by a narrow margin.

It is slow to heat, taking about an hour to get to our target temperature of 130 degrees Fahrenheit, with and without the lid on. However, it managed to heat our beverages to almost 140 degrees Fahrenheit in two hours with the lid on. Not that you’d likely keep your coffee or tea undrunk for that long, but you’ll appreciate that it keeps it piping hot in those rare instances that you do. Phone charging is slow sadly — it took more than an hour to get our iPhone from 50% to 82% — but it works, and it’s there when you need it.

While there aren’t any controls present, the auto-shutoff feature is simple yet very effective. It detects when the mug is overheated or hasn’t been moved for 60 minutes, it turns off on the dot. It also won’t start heating unless it detects an Ohom Ui 3 mug on it.

The charging pad is incredibly slim, but since the mug and lid are ceramic, it isn’t the most convenient to take to and from the office. If you love this mug, we’d recommend getting one for home use and another for the office. That is if you’re willing to pay that $99 price twice.

The SmrtMugg Pro has a cool LED display panel that not only shows you the current settings but says things like “hello” and “goodbye” when powering on and off. More importantly, it delivers solid heating performance and long battery life.

We love a great product with a fun flair and the SmrtMugg Pro is here to indulge us. We love taking this self-warming mug with us when we’re out on walks or on our way to yoga just to show off its retro pixel display that not only shows you the real-time temperature and the current heat setting but says things like “hello” when turning on, “goodbye” when powering down and “empty” when it doesn’t detect any liquid.

Lucky for us, it comes is a secure lid, making it travel-friendly. It’s not completely spillproof, but we haven’t had any spills yet. Plus, the mug itself is very easy to carry, thanks to its sleek design and wide handle.

Its heating performance is solid. It’s not as impressive as the Thermacup V2 and the Ember Mug 2, but it keeps your coffee warm for about four hours with the lid on. While its auto-shutoff function only works when the battery is low and it’s not on the charging base, it does beat the other two at charging time, taking only two hours to charge to full.

If you love the Ember Mug 2’s design but cannot afford to shell out $150 for a lid-less 14-ounce mug, it behooves you to know that the SmrtMugg Pro has a very similar look for less. It even has a matte satin finish like the Ember. At only $90, it might be a more economical pick.

If you’re looking for something cheap, the Misby Coffee Mug Warmer is a decent budget choice. Its unique feature is that it allows timed power-ons and shutoffs so you can schedule heating times based on your daily routine.

A solid yet cheap warming plate, the Misby Coffee Mug Warmer has some nice features that make it an easy recommendation for budget-minded consumers. It has a reserved start-up feature that allows you to set it to turn on at a particular time, getting it warm and ready for use, especially during hectic mornings. It’s also very lightweight and portable.

What’s more, it comes with an intuitive touch control panel. Its very responsive buttons give you access to five heating modes as well as timed shutoff. And for safety, it has an automatic shutoff as backup, turning off unprompted after eight hours of continuous use, which is a good thing, as that heating element is not exactly touch-friendly when on.

Its heating performance isn’t anything to write home about. It hasn’t managed to heat our drinks to our target temperature of 130 degrees Fahrenheit, only consistently topping at under 120 degrees Fahrenheit. It also vastly prefers flat-bottom mugs over others, so if you purchase it, make sure that you have a flat-bottom mug handy since it doesn’t come with one.

However, because it allows you to set timed power-ons and shutoffs, it’s the most customizable mug warmer we tested and quite useful if you prefer a more hands-off approach after the initial setup. That’s not too shabby for a product that will only set you back $24.

Seeking something more straightforward? The Bestinnkits Smart Coffee Set may be the best budget option for you. It uses a gravity induction switch for its heating element, offering a use-it-and-forget-it approach to heating your favorite hot beverage.

The Bestinnkits Smart Coffee Set had the very unlucky fate of being the first product we tested. Don’t get us wrong; it’s great for what it is. Because it doesn’t have any controls, it’s pretty straightforward to use. It uses a gravity induction switch so it only turns on when there’s a mug on it and automatically turns off when you remove the mug. We love that feature, as it takes some of the pressure off us to make sure that it isn’t overheating when it’s not in use.

We also love that it doesn’t turn on unless it’s on a stable, firm surface. We tried putting it on a cushioned ottoman, and it refused to heat, which is great from a safety standpoint. Finally, because it’s so lightweight, you can just toss it in your work bag and take it to and from work. It does come with its own mug, but you can use other ceramic and glass mugs as well.

Sadly, the Bestinnkits Smart Coffee Set was inevitably overshadowed by the mug warmers that followed it. Its heating performance is about on par with the Misby Coffee Mug Warmer, if only slightly better. Considering it only has one heat setting (131 degrees Fahrenheit), doesn’t come with any controls and has a slightly higher price tag than the Misby, it’s a little harder to recommend.

Mr. Coffee is known for its coffee makers so it makes sense that it’s thrown its hat in the mug warmer ring. This cheap and simple warming plate is best for budget-minded coffee drinkers who want something easy to use and only $20.

The Mr. Coffee Mug Warmer’s one-switch operation is a double-edged sword. On one hand, it makes it easy to use. You just need to turn it on and put your cup on the heating element, and it’ll start turning up the heat. On the other, you also have to remember to turn it off after every use since it has no auto-shutoff functions like the others. So, in that way, it’s a bit more high-maintenance.

What makes this one even harder to recommend is that while its one-heat setting is around 155 degrees Fahrenheit, it was slow to heat during testing and never really managed to heat our coffee above 130 degrees Fahrenheit. It couldn’t even make it to 125 degrees Fahrenheit after an hour and a half, even though the heating element did reach its top temperature.

Of course, we do have to account for the fact that the Mr. Coffee Mug Warmer is only $20 and the cheapest one in our testing pool. If you’re looking for mug warmer with a bargain-basement price tag and are not too particular about getting your coffee piping hot, this might just do the trick for you. It’s also on the lightweight side so you can easily take it anywhere.

The Cosori Original Automatic Coffee Warmer offers a wider heat range, allowing you to set it at up to 230 degrees Fahrenheit. If you like that brushed stainless steel look, this one will also match your aesthetic nicely.

Though Cosori is best known for its kitchen appliances — the brand’s air fryers are very popular — it also makes a mug warmer. Sadly, it’s also the worst performer of the bunch we tested when it comes to heating. Though its heating performance did improve with the lid on its included mug, it took an hour and a half for our beverages to heat 15 degrees higher. And those drinks never really got hotter than 120 degrees Fahrenheit, even when set to 130 degrees Fahrenheit.

We do think it’s just a matter of Cosori swapping the included stainless steel mug for one that’s better at heat retention. If they sort that out, as well as throw in an auto-shutoff function, this has the potential to be one of the best warming plates on the market.

Both the touch control panel and the LED display are great, and we like that it beeps every time you adjust the setting. It also has a wider heating temp range of 77 degrees Fahrenheit to 230 degrees Fahrenheit, giving you more heating options. With a better mug, this would be a much better value than what it is now for its $40 price tag.

It’s worth noting that the Cosori website says that the Cosori Original Automatic Coffee Warmer and Mug has an auto-shutoff, but the manual doesn’t say how it works exactly.
