Ember Temperature Control Smart Mug 2, 10 oz, Stainless Steel, 1.5-hr Battery Life
The Ember smart mug is our favorite heated mug. It has the longest battery life, and is easiest to use.
The Ember Temperature Control Smart Mug app is a noteworthy improvement, but only when the mug is fully charged, and even then, the app is buggy. Otherwise, this is a simple, well-designed, and reasonably priced heated mug. It's easy to use and has a sturdy, modern design, with a great-looking stainless steel finish. It's designed to heat and cool quickly (no more than 30 seconds between modes), so you can always pour in a fresh cup. The default settings are right on, and the Ember app is easy to use, with helpful hints and how-to articles. The controls are intuitive, and the app makes it easy to create custom presets just the way you like them. The Ember was our top pick before the app was updated, and it remains a great option, but the new app means that the new mug enhancements, while certainly useful, aren't as significant as they once were.

NEW Glowstone Smart Mug 2
This self heating mug is for serious coffee drinkers. It's beautiful but the $200 price tag puts it out of reach for most.
This is by far the best Wi-Fi automatic mug we've tested. The heating element is built into the mug and uses a controlled-heating system to maintain a consistent temperature for 1 hour. This means that you won't have to keep the mug at the optimal temperature, and it lets you take it with you wherever you go. The mug also has a built-in charging coil (supplied with a USB adapter, but a wireless charging plate is also available). The mug does not heat up while you're drinking and is mess-free, as the mug sits directly on top of your drink, rather than below it. The mug's fine bone china construction feels more expensive than it is, and you'll find yourself enjoying higher quality beverages.

Ember Temperature Control Travel Mug 2, 12 oz, Black, 3-hr Battery Life
The Ember Temperature Control Travel Mug retains heat for hours, brews your favorite coffee, iced coffee or tea, and looks good in any room of the house. Plus, it comes with an Ember smart device thermostat you can use without Bluetooth or wifi.
The Ember Travel Mug 2 deserves the highest recommendation. In addition to its vastly improved battery life, the improved screen, and redesigned charging coaster, the Ember is hands down the best heated travel mug we've tested. The 2-hour max hot time on the included charging coaster is an improvement that's barely noticeable, but it does allow this heated mug to sip your beverage for hours at a time. The mobile app and presets are a nice touch, but they don't impact our overall rating. You're more likely to use the app to access various preset temperatures, but the app is pretty intuitive, and you can make custom presets if needed. The Ember app also keeps track of which preset you used last, so you can save your favorite setting in the app. The Ember also charges pretty quickly. In our tests, it charged fully from the included coaster in just one hour, but it charges even faster with a normal USB charger. The Ember's screen is also pretty responsive, and it didn't have a problem detecting taps or swipes. The Ember is comparable with the Gourmia GoGo , and while the Gourmia is slightly cheaper, the Ember's longer battery life and improved features make it the superior choice.

Ember Temperature Control Smart Mug 2, 14 oz, Black, 80 min. Battery Life
The Ember smart mug is a great value. While it doesn't heat your coffee as evenly as the Contigo, it makes a good cup of joe and keeps the coffee hot.
The Ember Smart Mug is an excellent product (and our top pick). You get a very customizable temperature control system, a durable heat-resistant surface, a fast charge, and a maximum battery life that tops all of the others we tested. The only drawback is that you have to pay extra for the simple charger, and if you need a replacement, or one that will work with your car's 12V outlet, you'll have to buy that separately. But otherwise, the Ember is the best smart mug product you can currently buy.

EAST MOUNT Heated Coffee Mug
EAST MOUNT Heated Travel Coffee Milk Water Warmer Cup, with Long Lasting Rechargeable Battery & LCD Display, allows you to have your favorite drink at any time. With the practical electric mug, you don't have to wait for your coffee to be brewed in the morning, you can enjoy your favorite drink at any time.
This smart travel mug is well-designed, easy to use, offers a variety of useful features, and is built to last. The manual says it can hold 12 ounces of liquid, but we detected no problems with filling it all the way to the top. The mug has a precise temperature setting dial, which keeps the system nearly vibration free. The display is large, bright, and easy to read, and the controls are easy to understand. The mug has convenient handles to make it easier to carry, but it's best used on anything stable and level, like a desk or table.

Muggo 12 oz Temperature Control Mug with 3 hour Battery Life
The Muggo is a versatile travel mug that delivers incredible heat for hot beverages and tea at an affordable price. This mug's ergonomic handle, simple touch display, and 3-hour battery life are some of its best features.
The Mugo Portable Electric Tea & Coffee Warmer is a great compact and stylish way to enjoy hot drinks, even when you're on the go. The Mugo is compact and portable enough to fit just about anywhere, and it includes a clip to easily attach it to your bag when it's not in use. The touch display is intuitive, easy to use, and requires no tools or additional items. You can adjust the temperature using the buttons, and when the lid is open, it's easy to pour your beverage out without spilling. The heating element is concealed in the bottom, but it heats quickly and reliably, and the battery lasts long enough to enjoy a hot drink through one work shift. Overall, this is a great portable electric travel mug solution.

Temperature Control Mug Travel Heating Cup LEJIEYIN Electric Heating Cup for Coffee in Car 12V Heated Mugs Smart Coffee Cup Keep Milk/Tea Warm LCD display Easily Washing 13OZ (Black)
The heated coffee mug is a superb way to heat coffee in a hurry-or at home. It's the best pick for car travel, but it makes a great home accessory for heating tea and milk or soup.
We were hesitant about the Lejieyin Electric Heating Cup at first, given the price, but the traveling mug turned out to be one of our favorites. The maker claims the mug works on 110, 120 and 24 volts outlets, but the only one that I had running in my car was 12 volts. That didn't stop the Lejieyin from heating up quick and putting it through its paces, and though it does heat up quickly, it warms up slowly enough for slow pours. Despite being the smallest and lightest of the mugs we tested, it has a 13oz capacity, which is perfect for most 12-oz cups of coffee or two larger cups of tea. The only downsides for us were the limited temperature control (we could only select and adjust temperatures between 81-194 degrees Fahrenheit), the sometimes erratic temperature readout (which, to be fair, seemed to be related to our outlet), and the somewhat awkward lid, which doesn't seal if it's tilted too far upward. That said, the fact that the lejieyin uses auto shutoff and comes up empty if it's left running for too long (another safety feature) makes it a reliable road trip companion. The only time we experienced any issues was when we accidentally overheated the mug and burned it. We would recommend the Lejie Yin to anyone traveling by car, especially those who like to drink coffee or tea on the road.

Funchic Heated Travel Mug Electric Coffee Mug Warmer 12V Thermos Cup Intelligent Travel Mug with Temperature Control for Car
Funchic travel mug can heat up coffee, tea, milk, cocoa or other beverages. The insulated food container can keep drinks and food hot up to 9 hours or cold up to 12 hours.
This travel mug was cool enough not to burn our hands after holding it for about 3 minutes, but it took about 10 minutes to bring it up to a comfortable temperature. The design was easy to grip, and the travel mug was small and light enough to carry without feeling like we were lugging around big, heavy brick. The USB port didn't provide enough power to charge a phone, but the travel mug did charge a GPS device quickly and provided enough power for a full-day trip. The travel mug was easy to find because it came with its own matching car charger, which was a nice bonus. We also liked that this travel mug was easy to carry because it had a carrying handle, and it felt lighter than many mugs we've tested.

Smart Temperature Control Travel Coffee Mug EAST MOUNT Electric heated Travel Mug 12V Stainless Steel Tumbler Smart Heating Car Cup Keep Milk Warm LCD display Easily Washing Safe for use (Black)
The travel coffee mug electric heated is considered the highest quality and value. The ceramic design maintains heat, and is very easy to clean.
The EAST MOUNT Car heating cup is very hot and attractive, the stainless steel surface is not easy to rust, the texture is very beautiful and feels good, it is a beautiful car travel mug. I was mainly interested in its heating function and microwave oven application. The first time I used it, I found that the electric heating cup had a very good heating effect, heating fast and quick. The milk in the heating cup was turned black at about 90 minutes, but there was no leakage, and the power cord was pulled out after the milk was sprinkled, so there was no problem. The safety of the EAST MOUNT car heating cup is very important. The power cord of the EAST MOUNT electric mug can be pulled out, which is a good safety guarantee. When using the EAST MOUNT car heating cup to microwave, the EAST MOUNT car heating cup is very convenient. It takes about 60 seconds to heat the milk to 88 degrees. After the milk is poured into the car heating cup, the EAST MOUNT car heating cup can be used in the oven, and the milk will gently heat up. The temperature can be automatically adjusted according to the temperature.

Smart Temperature Control Travel Coffee Mug GEEZO Electric heated Travel Mug 12V Stainless Steel Tumbler Smart Heating Car Cup Keep Milk Warm LCD display Easily Washing Safe for use (Green)
This "smart" thermos is simple to use and will keep drinks hot for hours. It's also very reasonably priced and has a good track record on Amazon.
This travel mug is pretty easy to use, but it's a bit confusing at first. You power on the mug by pressing the "+" or "-" buttons, and once the "+" appears, the mug is heating up. Then, you press the "+" or "-" buttons to set the temperature, and when the blue button is displayed, the mug is heating. When the blue button is displayed, you can taste it and enjoy the pleasure of drinking coffee or tea from the first mouth to the last drop.

UniqueMax Coffee Mug Warmer
A great mug warmer and coffee warmer, the UniqueMax coffee mug warmer is affordable and works quite well.
The Uqunique Max Air Mug Warmer and Warmer Mugs, 14 oz, Wireless Charging, Cup Warmer, Temperature Mug for Office and Home Use are pretty much the same, but the warmer mug has a more stylish appearance. The warmer mugs have an edge when it comes to heating liquids, but are a bit more expensive, and they don't charge mobile devices. The Uqunique Max is nicer to look at, is less expensive, and is wireless (which may be preferable when charging a phone is involved). Both warmer mugs are efficient at keeping your drinks hot, but the Uqunique Max heats much faster than the warmer mugs, though both do a good job of keeping your drinks warm for a long time. While it's nice to have automatic, heat control, the Uqunique Max does cost twice as much as the warmer mugs, so we recommend the warmer mugs for most people.

Soniker 12V/24V Smart Temperature Control Travel Coffee Mug
This smart heated mug is easy to clean, keeps beverages at the perfect temperature for hours. And it is perfect for a hot or cold drink.
The Soniker car coffee/tea mug is a compact coffee warmer with a sturdy, stainless steel body that automatically heats a beverage keeping it warm for hours. The mug comes with a built-in battery to heat your beverage up to 200 degrees Fahrenheit (93 degrees Celsius). The mug can heat any liquid or beverage including coffee, tea, hot cocoa, soup, milk, and more. The mug comes with a switch to stop and restart the heating, as well as the auto-off function. Plus, the mug comes with a convenient lid so you can keep the liquid warm while you're driving.

YEOSEN Coffee Mug Warmer and Cooler
This mug warmer and cooler is our favorite pick for keeping your drink maintained at the desired temperature every time.
The Yeosen Mug Warmer is a decent option for those looking for a compact mug warmer that's easy to carry, and if you do most of your drinking at home or the office, its variety of uses make it an excellent choice. Its temperature controls are debatable, and this cooler doesn't cool as easily as other pricier coolers. But if you're willing to spend a bit more, the Yoosen Mug Warmer is what we'd recommend.

Ember Temperature Control Smart Mug, 10 Ounce, 1-hr Battery Life, White
It has an iPhone app that lets you use the app to set the temperature of the mug, and the app will notify you on your smartphone when the mug has reached the proper temperature for your preferred beverage. The ember mug is advertised as keeping coffee hot for two hours, but we found that it kept coffee warm for about 90 minutes.
The Ember Smart Mug is a beautifully crafted, well-designed, and user-friendly smart mug that keeps your coffee or tea at just the right temperature. The Ember is intelligently designed to heat your drink and pause when it needs to cool down. The mug uses an app with offices in California and Pennsylvania and is backed by a 2-year warranty. Its app serves the dual purpose of informing you about your mug's status, enabling you to control it, and serving as a portal for other potential features like Alexa integration. The app, while well-designed, is ugly as a sin, though you can at least customize the colors of your Ember's LEDs to help mask its ugliness. The Ember uses a proprietary connection that requires drivers to be installed on Windows machines, which some reviewers have complained of. On top of that, the Ember charges over a micro USB connection, so you'll need an Ember charging coaster (included). But as a coffee person, the more settings I can get in my automated coffee maker, the better.

Smart Mug Warmer with Double Vacuum Insulation,VSITOO S3 Pro App Temperature Control Coffee Mug Warmer with Sliding Lid, 4-Hr Battery Life
This smart mug is a great gift idea for family and friends. It’s easy to use, just slide the lid up, add hot water and push the button. This mug can keep your coffee hot for 4 hours.
VSITOO S3 Pro smart mug is a coffee maker, tea maker, and hot water dispenser in one. It heats water to 180oF-205oF (82oC-98oC) to brew hot or cold beverages, and maintains a safe, comfortable temperature for hours. The heating process takes 2-3 minutes, and the sliding lid with handle and anti-slip surface helps to prevent spills. The mug is made of double-layer, vacuum stainless steel, and the inside adopts advanced Food Grade Ceramic Acrylic Paint Technology, which makes it more durable and safer. The insulated mug keeps beverages warm for up to 7 hours, and keeps beverage hot for 2-3 hours after drinking. VSITOO S3 Pro smart mug uses 2500Ah high-capacity polymer lithium battery, which is incased in the mug body. It is IPX7 waterproof rating, you can clean the smart mug more safely. The smart mug fits most mugs up to 14oz (400ml), making it a great choice for office, home or travel. The infrared sensor detects your mug and switches on the heating pad and lights automatically. It is easy to operate and maintain.

VSITOO Coffee Mug Warmer&Mug Set
The mug set is well-designed, easy to use and provides the right amount of heating. The heating time and temperature are adjustable, and there's also a built-in timer.
The VSITOO smart ceramic coffee mug is a great gift idea for the cat lover in your family. It will keep your coffee or tea hot for hours. The mug has three different temperature settings to help you brew the perfect cup - and to stay warm as long as possible. I like that this mug has an indicator light and that you can control the temperature from your smartphone. The bottom of the mug also has a built-in stand that helps insulate the cup. The mug feels sturdy but is still lightweight enough to use without getting tired. The only negative is that the mug is a little difficult to clean. The bottom of the mug is made of ceramic, so it can be hard to scrub off coffee or hot chocolate stains.

Yeewell Coffee Warmer
Best for office use, or as an office coffee and tea station. This smart mug warmer works without a computer or internet, and shuts off when your coffee cools. The wider plate, 1.5 inches, helps accommodate larger mugs, and the red, white, and blue design looks festive.
The Coffee Warmer is a smart electric mug warmer that uses infrared heat to keep beverages warm. It has 2 temperature settings, and the microwave and oven-safe mug it uses lasts 1.1 hours (220°C) or 1.6 hours (230°C) per use. The mug warms up quickly and evenly, and its 7.4-inch diameter and 5.3-ounce capacity make it compatible with a wide range of mugs and cups. It heats quickly and evenly, and the controls are simple and self-explanatory. The auto shut-off feature means that you won't have to worry about the mug overheating if you leave it alone for a while. However, the mugs we tested were too thin to be safe for microwave use, and the 2.0-amp USB port it only has enough power to charge one device at a time. The Coffee Warmer is a solid mug warmer, especially for the price.

COSORI Coffee Mug Warmer & Mug Set
This electric mug warmer looks nice, keeps drinks hot, and is backed by a lifetime-warranty. The digital thermostat is programmed to keep the contents hot for up to 5 hours, but its steam mechanism has been known to cause some early failures.
The COSORI coffee warmer keeps a cup of coffee hot long enough for you to finish your morning ritual and sip it slowly. While it's not for really long, a 10-minute brew time is long enough to brew a strong cup. It also takes less time to heat up than most mugs. And, unlike most electric coffee warmers, which are too big for your desk or countertop, COSORI's tiny design fits easily on the counter or in a small office drawer.

VOBAGA Imitation Wood Grain Coffee Cup Warmer & Mug Warmer For Desk
The cup warmer is beautifully designed, comes with three temperature settings and automatic shut off function, which is soft and comfortable and can help you drink hot water in cold weather.
This mug warmer is great. It has three different temperature settings, a blue light to let you know when the plate is hot, and an auto shutoff after 4 hours. It's perfect for keeping a cup of coffee warm on a cold morning, and for keeping it warm for tea in the afternoon. It also keeps your milk warm without burning it. The mug warmer is made of plastic, so it won't break and the plastic is still pretty durable. I can definitely see myself using this all summer long.

Ember Temperature Control Smart Mug 2, 10 oz, Black, 1.5-hr Battery Life
The Ember is a heat-controlled mug that lets you set your preferred coffee temperature, adjust the heat, and track your usage and battery life in the app. It's one of our favorite budget smart mug choices, thanks in large part to its development over the years and to the Ember team's willingness to accept user feedback.
The Ember smart mug 2 has a slightly redesigned lid that makes it easier to open, and it's now splash-proof. The charging coaster is longer-lasting, too, with a redesigned footprint. The mug itself delivers 10-15 minutes of heating time, which is enough for a cup of coffee. (It also lasts for about 12 hours if left unplugged overnight.) The mug also pairs with a smartphone app with support for 15 different presets, as well as the ability to customize each preset. It also syncs with Apple's HomeKit, so you can use Siri to adjust the temperature. The sound quality isn't great, but it's adequate for a coffee-water heater. Speaking of water heating, the mug comes with an upgraded heating element and a special water heating coaster. The Ember app has a handful of utilities, including the ability to control several other Ember accessories like the Ember Kettle, Ember Glass, and the Ember Desktop. But if you're spending $100 on a smart coffee mug, you probably want something that's more smart than smart mug. The Ember app and app-controlled features like presets and notifications are good, but they're by no means necessary for basic functionality. And, of course, the app isn't free. But if you have a smartphone, Ember is one of the few smart mugs you might want to consider.

Ember Temperature Control Smart Mug, 14 oz, 1-hr Battery Life, Black
The Ember heated coffee mug is definitely the coolest, most sophisticated gadget we tested. The mug pairs with an app on a smartphone, allowing you to monitor the temperature, customize presets, and receive notifications.
The Ember Smart Mug is a smart take on an age-old problem: wanting to drink hot coffee, tea, or a cocoa but not waiting while your mug heats up until it's just right. That's the idea behind Ember Coffee Mug, a smart, heated mug that heats your drink as you need it, using your smartphone as the controller. You set the mug's temperature through the Ember app; the app has a countdown timer to let you know when your coffee is ready. Your Ember mug has a battery that will last up to an hour, and it comes with a coaster to keep it floating while it's charging. The app also notifies you when it needs charging (it's recharging itself when the Ember is plugged in). In our tests the Ember Wireless Smart Mug delivered on our promise of keeping drinks the right temperature between 120°F and 145°F. In the 120°F range, the mug kept our coffee warm until we felt an urge to drink it (we probably could have waited much longer, but admittedly, we were impatient). The mug's built-in safety features shut off the unit if it gets too hot or too cold, and you can unplug it from your computer, smartphone or laptop when you're finished; there's an automatic shut-off after about three hours. The sensor on the mug is responsive and accurate, and the mug is durable and feels well-built. The matte black finish looks elegant and classy, and it hides fingerprints easily. The Ember mug is no slouch on battery conservation, either; the smartphone app and accompanying charger allows it to last up to an hour, assuming you use it just once a week. The app also lets you customize saved recipes, so you can create regular (or specialty) beverages. The Ember Smart Mug is more expensive than typical mugs, but it's one of the few smart-heated mugs on the market.

Adeney Coffee Mug Warmer with Mug
This mug warmer works well with mugs, pots, and glasses. The unit heats up quickly and evenly, and its design means you can leave it plugged in all day long.
This coffee mug warmer is very easy to use and is especially useful, since it keeps coffee warm without burning your fingers. The coffee cup warmer is more than I expected. With it, you can drink your hot coffee anytime and anywhere you want. Now coffee time will be more joyful, more enjoyable.

APEKX Auto On/Off Gravity-induction Coffee Mug with 24Watt Intelligent Temperature Control 113°F/45°C Cup Warmer Self-Heating with Wireless Charging Function Gifts for Home Office (Mug Included) White
If you are like many people, you wake up in the morning and the first thing you do is grab a cup of coffee. It is an essential part of your morning ritual, but in some cases, the mug you use can be a little flawed. You find yourself holding the mug with your hands when you should hold it with your arm, you often place a coaster on top of it to protect your table, and you end up spilling your hot coffee all over yourself. The Auto On/Off Gravity Induction Coffee Mug from APEKX solves all of those problems with one easy-to-use coffee mug that will quickly become your go-to mug in the morning. This mug is built to be durable and functional.
Like the BGR Top 9, the APEKX coffee mug is an unusual choice for our list, but it's extremely functional. Weighing only 2.1 pounds, it has built-in temperature controls so your coffee stays warmer, longer, and it doubles as an insulated mug that you can fill with hot liquids like coffee or hot chocolate. It has built-in wireless charging, so you don't need to lug around your wireless charger or plug in a USB cord. The charging signal is pretty weak, so don't expect it to work great with an iPhone or Android phone, though you can use any Qi-compatible phone. The heaters in our tests were rated by UL for safety, so you can feel good about tossing this mug into the microwave.

BESTINNKITS Smart Coffee Set Auto On/Off Gravity-induction Mug Office Desk Use
This wax warmer is not as good as a mocha pot or sukiyaki pot, but it would be reasonable as a backup heat pot if your coffee maker has issues.
This mug warmer is easy to operate and has decent heating performance. It's better than some products we tested since it heats quickly and evenly, and it holds its temperature well, so it always feels warm when I use it. It's made of flame retardant materials, so it's also a good choice if you have small children in the house. However, there's no auto shutoff, so you'll have to remember to unplug the charger when you're done with the cup, and this warmer only works with mugs. It's also not particularly attractive, which isn't a big deal when you're using it as a mug warmer, but it certainly wouldn't be as handy as a coffee or hot chocolate cup, either. Also, you have to unscrew the mug before placing it in the warmer, which is slightly annoying. I think the warmer would be much more convenient if it automatically heated the mug and placed the cup in it when you flipped the switch.
