The Kin Element Mug Warmer is reasonably priced yet offers a number of convenient features to help users get the most out of their coffee. The all-around value of the item makes it our top pick. As an alternative, the Ember Mug² is a high-tech—albeit pricy—coffee mug that keeps drinks at the desired temperature without the need for a separate heating device.
If you often find yourself heading to the microwave to reheat your morning java, there could be a better solution. While a quick nuke certainly does the trick, it can take away coffee’s original flavor, leaving you with a less-than-desirable cup. Another option is a mug warmer. These convenient heated coasters can keep liquids warm for several hours, allowing you to enjoy your cup of joe throughout the day without interruption.
Whether you’re a coffee connoisseur who wants the latest gadget with all the bells and whistles or someone who longs for something basic, there are a number of options available on the market to suit every preference.
Here are the best coffee mug warmers.
Best Overall: Kin Element Mug Warmer and Lid Set
Adjustable heat settings
Extra long cord
Top is flat, no rim
Only available in black
Users hardly notice this sleek and subtle mug warmer in their homes—until they take a delicious sip of hot coffee, that is. It has three temperature settings that range from 104 to 140 degrees. To alternate between settings, simply touch the front-facing sensor. The sensor also changes color to denote if the temperature is high, medium, or low.
While this model needs to be plugged into an outlet like most warmers, the 72-inch cord is longer than average and should reach any side table or coffee table. The brand throws in a unique touch with a dishwasher-safe silicone mug lid, which provides extra temperature insulation for coffee, tea, or hot cocoa. The item also an automatic shutoff after five minutes of inactivity for safety.
One possible drawback is that the warmer's surface is totally flat, whereas some models out there have rims to give mugs extra stability. For the most part, though, it's easy to safely place a mug on the Kin warmer without fear of spilling. There's even an added bonus that the lack of rim makes the surface slightly larger, accommodating bigger mugs. The base measures 4.5 inches total in diameter, but the actual heating part is 4 inches.
Dimensions: 1 x 4.5 inches (H x D) | Cord Length: 72 inches | Wattage: 18 watts
Best Mug: Ember Mug 2
Long battery life
Modern minimalist design
Interior coating is delicate
This mug warmer has a slightly different concept in that the mug itself heats the coffee instead of the coaster. There is a base included with this mug, but it acts as a charger rather than a heating point. The battery life for the 10-ounce model lasts around 90 minutes, while the 14-ounce model lasts 80 minutes.
The mug and coaster are sleek in design, boasting a minimalist aesthetic. There are several colors available, including black, white, gold, copper, and stainless steel. Beyond looking great, this mug warmer offers ultimate control by allowing users to choose their preferred temperature—between 120 degrees and 145 degrees—through the Ember app. Once the temperature has been reached, the indicator light on the mug’s bottom will flash.
For best cleaning practices, this mug must be carefully washed by hand and should not come in contact with abrasive cleaners, as this could cause permanent damage.
Capacity: 10 or 14 ounces | Dimensions: 3.25 x 4.2 inches (10-ounce model) | Weight: 14.5 ounces (10-ounce model)
Best Budget: Home-X Coffee Mug Warmer
Easy to use
Rim adds stability
This affordable option is easy to use and travels well if needed. The heating plate measures 3.5 inches in diameter and has an on/off switch with a bright red light indicator on the plate. In terms of design, it’s very simple with a plain exterior and a spot for the mug to rest. It should only be used with ceramic and glass mugs, though. For best cleaning practices, just give it a wipe after use.
Keep in mind that the cord is rather short, measuring 42 inches. Another slight drawback is that the item is lightweight and the materials may not be as high quality as that of other, pricier mug warmers. But considering the low price, the item offers great value.
Dimensions: 5.6 x 7 x 1.5 inches | Cord Length: 42 inches | Watts: 17 watts
Best With Cord: Norpro Decorative Cup Warmer
Easy to use
No auto shutoff
Temperature isn't adjustable
Who else recommends it? Best Products and Bob Vila both picked the Norpro Decorative Cup Warmer.
What do buyers say? 87% of 2,500+ Amazon reviewers rated this product 4 stars or above.
The Norpro coffee warmer is both functional and stylish. It has a heating plate that measures 3.75 inches, which is on the wider side and accommodates bigger mugs. It also includes an extra-long cord measuring 60 inches, allowing you flexibility as to where you can use it. There's a simple toggle switch on the cord to turn the warmer on, and there's an indicator light on the front to show when it's heating.
Another nice aspect of this mug warmer is its beautiful design. If you’re looking for something eye-catching, the base is made out of porcelain with a faux marble pattern. Unfortunately, that's the only design available, as opposed to other mug warmers that have multiple colors or patterns.
This is a 24-watt warmer, which is on the higher end for a heating coaster. Reviewers say that it keeps coffee hot for about three hours. The heating plate is nonstick and requires a simple wipe down after each use.
Dimensions: 1.25 x 3.75 inches (H x D) | Cord Length: 60 inches | Wattage: 24 watts
Best for Desks: Bestinnkits Gravity-Induction Mug Warmer
Large surface for mug
Automatically turns on
Temperature isn't adjustable
This mug warmer is very slim, so it won’t take up a lot of room on your desk. It has a built-in gravity induction switch that automatically turns on when you set your mug down and shuts off when you remove it. In terms of design, this mug warmer is simple, but sleek, boasting a minimalist aesthetic. Choose from several colors, including black, white, and pink.
The 19-watt mug warmer keeps coffee at a temperature of 131 degrees, and reviewers say it’s very easy to use. It's also waterproof, as the heating plate is covered with a layer of thermal conductive glass. It requires a wipe-down after each use to keep it in good working condition. One of the biggest drawbacks is that the cord is shorter than most at around 40 inches, so maybe consider the distance from your outlet to coffee table before purchasing.
Dimensions: 1 x 5.2 inches (H x D) | Cord Length: 40 inches | Watts: 19 watts
Best Crochet: Nandy's Nook Hand Crocheted Mug Wrap
Handmade and good quality
Easy to fasten button
Won't fit all coffee mugs
Not as effective as electric warmers
For a non-electronic way to heat your coffee, you can use a mug sleeve, such as this handmade crocheted wrap from Nandy’s Nook. This cozy contraption, made of 100 percent acrylic yarn, wraps around the mug and connects in the front with a wooden button. There are several color and button options available, measuring 10 inches in circumference and 3.75 inches in height.
One benefit of this mug warmer is that it has the added benefit of protecting the user’s hand from an otherwise too-hot mug. Reviewers love it because it's well-made and it makes for a great gift. Each item ordered comes with gift-ready packaging, too.
In terms of cleaning, the manufacturer recommends washing by hand and laying flat to dry. This mug sleeve can also be machine-washed in warm water and tumble-dried.
Material: 100 percent acrylic yarn with wooden button | Dimensions: 3.75 x 10 inches (H x C) | Color Options: 8 colors
Best Design: Cosori Original Coffee Warmer & Stainless Steel Coffee Mug Set
Comes with coffee mug
Easy to use
Displays precise temperature
Stands out more than other warmers
Steel mug can get too hot
For the coffee aficionado, this mug warmer has a number of features that offer more customization than some other heating plates. Not only does it boast a sleek look with its brushed stainless steel finish, but it also has touch-tech controls, an LED temperature display, and a water-resistant plate. Temperature readings are precise down to a single degree.
At 24-watts, this plate can keep beverages between 77 and 158 degrees. As a bonus, it even comes with a 17-ounce stainless steel mug with a cool-touch handle and silicone slip-resistant sleeve. Of course, this fits perfectly onto the warming plate.
To prolong the lifespan of the stainless steel mug, it should only be washed by hand. The warmer should be wiped with a damp cloth and dried immediately.
Dimensions: 4.2 x 5.3 x 0.7 inches | Cord Length: 61 inches | Watts: 24 watts
Best With Auto Shut-Off: Vobaga Coffee Mug and Cup Warmer
Three temperature settings
Available in multiple colors
Not the easiest to clean
If you’re someone who easily forgets things, this coffee warmer comes with an automatic shut-off feature, which kicks in after four hours. Once the warmer powers down, a blue light will flash to warn users that the heating plate is still hot.
This coffee warmer has three temperature settings, including 104 degrees, 131 degrees, and 149 degrees. The 20-watt device also has a waterproof design that helps to protect it from the occasional spill. The heating plate measures 3.5 inches, which should accommodate most cup sizes, and the cord measures 59 inches, which is on the longer side.
This warmer should be wiped down after each use. The only inconvenience that some reviewers have found is that the indented surface, which helps to accommodate the shape of the mug, makes it a little more difficult to clean versus a flat-top surface.
Dimensions: 5.3 x 4.5 x 0.9 inches | Cord Length: 59 inches | Watts: 20 watts
What to Look for in a Coffee Mug Warmer
If you've got an eye for style, you'll probably want to consider how this piece will look sitting on your desk, or your counter, for several hours, with the rest of your decor. You might also like a warmer that has an automatic shut-off feature, or one that's rechargeable and holds a charge for a long time.
The ease of care for a new kitchen gadget is another consideration. How easy is it to keep clean? Is it made of delicate materials that break easily? Most of these devices can be simply wiped down with a clean damp cloth after use and dried immediately.
In this case, size refers to two things that may or may not be present in every mug warmer available. First, you want to look at the size of the base, the warming device itself. Mug warmers don't typically take up a lot of space, but will the warmer accommodate your favorite mug if it's oversize? Additionally, some of these products include both a warmer and a mug designed specifically for this dual purpose. Make sure the size accommodates your coffee drinking needs.
Are coffee mug warmers worth it?
If you are serious about your coffee, the answer is yes. If you tend to drink your coffee over the course of several hours, get distracted easily, and/or have a habit of microwaving it to heat it back up, a warmer is a great solution. Coffee warmers also keep the coffee fresh tasting in addition to keeping the temperature consistently hot. Furthermore, they come at a number of price points, which can help you find the right one for your budget. Coffee mug warmers make a great gift for the serious coffee lover in your life.
Are mug warmers a fire hazard?
Many of these warmers have an auto shut-off feature and/or the ability set the coffee to a specific temperature. Exercise common sense and don't leave the item unattended for long periods of time, and definitely don't leave it plugged in if you have to leave the house. If you are at all concerned about a fire hazard, buy one that automatically shuts off.
Do mug warmers work with any mug?
Many will work with ceramic, glass, or metal mugs, but some of the brands we profiled here come with their own specifically designed proprietary mug.
