If you often find yourself heading to the microwave to reheat your morning java, there may 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 precious 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.

Best Overall: Norpro Decorative Cup Warmer

Norpro Decorative Cup Warmer

The Norpro coffee warmer is both functional and stylish. It has a heating plate that measures 3.75 inches, which is wider than some others, accommodating bigger mugs. It also includes an extra-long cord measuring 60 inches, allowing you flexibility as to where you can use it. The on/off switch at the front features a neon light indicator.

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, it comes with one downside: The porcelain can easily break if dropped. 

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.

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 lasts around 1.5 hours and the mug holds up to 10 ounces.

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.

Best Rechargable: Muggo Self Heating Travel Mug

Muggo Self Heating Travel Mug

This is a wonderful option that you can take on the go. The set includes one heating coaster with two warming plates, one travel mug, and one lithium-ion battery, which attaches to the bottom of the travel mug. Battery life is estimated to last about three hours, so you can enjoy your hot beverage for a while without a recharge.

Another great feature is this warmer’s ability to heat your beverage on one side of the coaster while the other side simultaneously recharges the battery. You can also choose to charge two batteries at once or heat two mugs at the same time. The mug itself includes a touch display that allows you to select your desired temperature ranging from 95 degrees to 150 degrees. It's spill-proof and you can open it with a single click to sip from any side.

Best for Desks: Bestinnkits Gravity-Induction Mug Warmer

Bestinnkits Gravity-Induction Mug Warmer

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. Its cord measures 50 inches in length.

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 wipedown after each use to keep it in good working condition.

Best Crochet: Nandy's Nook Hand Crocheted Mug Wrap

Nandy's Nook Hand Crocheted Mug Wrap

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.

Best Design: Cosori Original Coffee Warmer & Stainless Steel Coffee Mug Set

Cosori Original Coffee Warmer & Stainless Steel Coffee

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 range from 77 degrees to 194 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.

Best With Auto Shut-Off: Vobaga Coffee Mug and Cup Warmer

VOBAGA Coffee Mug and Cup Warmer

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 60 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.

Best for Travel: Home-X Coffee Mug Warmer

Home-X Coffee Mug Warmer

This lightweight option travels well—its small size fits just about anywhere. It 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 (options include white or black) and a spot for the mug to rest. It should only be used with ceramic and glass mugs, though.

One downside is that the cord is rather short, measuring 42 inches. For best cleaning practices, just give it a wipe after use.

What to look for in coffee warmers

Design Features

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.
