What is a Mug Warmer?

A mug warmer is a heated coaster that keeps your steamy mug of joe from turning into a cold brew, providing you a calming reassurance of an enjoyable drinking experience without interruption. A mug warmer is a great way to keep your drink warm without ruining the flavor via scorching.

It uses heating coils in the same way as electric kettles and emits enough heat to maintain a consistent temperature. By the time you finish drinking your cup of joe, it will remain considerably warm.

All mug warmers claim to be able to maintain a specific drink temperature. The most commonly used mug warmers have ranges between 120 °F and 155 °F. The ideal temperature range for drinking is between 130 °F and 140 °F

The 7 Best Mug Warmers On The Market Today

When you’re drinking your morning joe or afternoon tea, the last thing you want is for it to be cold. While you can use the microwave, it’s not exactly the most effective way to keep your coffee or tea warm. Instead, go for a mug warmer. Each style has its own benefits and drawbacks—some keep mugs warmer longer than others, while some come with all the bells and whistles.

Here are the best coffee mug warmers you can buy today.

1. Smart Coffee Maker by Bestinnkits – Best Overall

Specs: Brand: Bestinnkits | Colors: Multiple | Item Weight: 9.2 Ounces | Item Dimensions: 7.17*5.63*1.34 inches | Power Source: Corded

This Smart Coffee Mug Warmer by Bestinnkits is a no-frills option that quickly gets the job done while maintaining a steady temperature of 3 °F and 135 °F for hours.

It contains a gravity-induction switch built-in that serves to automatically turn on the device when you place your mug on top of it and shuts off by itself when you remove it. In terms of design and convenience, this mug warmer is very slim and won’t occupy much space on your office desk as well.

Also, the heating plate of the item is covered with a thin layer of thermal conductive glass, making it highly waterproof & easy to clean. Users can also choose between several color options, including pink, black and white.

The only flaw I noticed is that the mug warmer runs on a 50 inches cord; therefore, you must have a power outlet nearby in order to use it. The lack of several temperature settings is also something you should look at before buying it.

Reasons To Buy

  • FCC & UL certificated
  • Waterproof design
  • 5”-diameter enough for big mugs

Reasons To Avoid

  • One temperature setting
  • Corded design

2. Norpro Decorative Cup Warmer – The Runner-Up

Specs: Brand: Norpro | Color: White | Item Weight: 35.2 Ounces | Item Dimensions: 5*5*1.5 inches | Power Source: Corded

Norpro is another simple yet efficient mug warmer for those who prefer aesthetics over functionality. 

The product’s white surface is marble-like and comes slightly wider at 3.75 inches than can easily accommodate larger mugs. The 24-watt heated element is nonstick and is easy to clean with wipes. In addition to that, the on/off switch features a neon indicator light as well, which lets you know when your mug has reached the required temperature.

Aside from its design and efficiency, the only downside is that the item does not feature an automatic shutdown function, so you’ll have to switch off it on your own. Also, the porcelain finish is prone to break if not cared for properly.

Reasons To Buy

  • Functional and stylish
  • Extra-long cord
  • Neon light indicator installed

Reasons To Avoid

  • One-heat setting
  • Not automatic shutdown

3. Ember Temperature Control Smart Mug – Best With Mug

Specs: Brand: Ember | Colors: Multiple | Item Weight: 38.72 Ounces | Item Dimensions: 6.06*5.55*5.47 inches | Power Source: Rechargeable battery

This coffee mug warmer from Ember is quite different from its competitors in the sense that it heats itself with a built-in battery and heat source that can be used independently from its included coaster.

The included base of the warmer acts as a charger instead of a contact heating point. Meaning, you can walk around with coffee without worrying about getting it cold. The Ember Mug pairs with your smartphone over Bluetooth and sends you a notification once the desired temperature is reached.

You can purchase the Ember Mug in 10 and 14-ounce capacities, each having a battery life of up to an hour and a half. Users can even specify any particular type of beverage with the app so that it’ll recommend the ideal temperature for each ranging from 120-145 degrees.

  • 1.5 hours battery life
  • App controlled
  • Shuts off automatically

On the negative side, the warmer’s surface is only suitable for thin-walled, slightly concave-bottomed mugs and is relatively difficult to clean versus a flat-top surface.

Reasons To Buy

  • Several color choices
  • 3-temperature settings
  • Automatic shut-off
  • Safe & Durable

Reasons To Avoid

  • Difficult to clean
  • Corded design

5. Cosori Coffee Mug Warmer & Mug Set – Best Durable

Specs: Brand: Cosori | Color: Silver/Black | Item Weight: 17 Ounces | Item Dimensions: 5.4*0.7*4.3 inches | Power Source: Corded

Not only that, it even comes with a 17-ounce stainless steel mug with a heat-resistant handle and rubber slip-resistant sleeve with the intent to protect your hands from burning. Of course, you can use this mug warmer with all types of mugs, including glass and ceramic ones. However, keep in mind that the company only encourages using the mugs with flat bottoms for the best possible results.

It features a sleek, low-profile design with a plain exterior. The overall size of the heating element is around 3.5 inches, which is enough to accommodate one large-sized mug conveniently.

The only downside is that the item doesn’t have an auto shut-off function; therefore, it’s your responsibility to turn it off after each use. The cord size is also a bit smaller measuring around 42 inches only.

Reasons To Buy

  • Cost efficient
  • Lightweight & Portable
  • Sleek, low-profile design

Reasons To Avoid

The only potential downside is that there’s no auto-off function. However, the handy red light indicator lets you know when it’s on. The device also doesn’t work very well in cold temperatures.

  • 17-watt heating element
  • On/Off switch with indicator light

Reasons To Avoid

  • No auto shut off
  • One temperature setting only

Things To Look For In A Coffee Mug Warmer

There is a lot to consider when buying the best coffee mug warmer, but most decisions have to deal with design, size, and temperature settings.

Best Coffee Mug Warmer - Cup Of Caffeine

Design Features

If you’re a coffee connoisseur who has an eye for style, you’ll probably want to make sure if it’s compatible with your favorite mug. If you don’t have one already, smart coffee mugs that come with their own warmer will do the trick. You might also want to match your device with the rest of your decor as it will be sitting on your desk, or your counter, for several hours. Most of these warmers have a sleek, streamlined appearance, while some come with a more decorative look, with faux marble or wood grain finishes.

Size Matters

Another important consideration is the size of your mug warmer. You’ll come across a range of sizes for mug warmers, with some slightly larger in size than the average coaster. Make sure the mug warmer accommodates your favorite mug. They come in flat or disc-like shapes.

Consider compact models with a small surface area aside from the heating element if you’ve got a limited space at your desk or counter.

Wired vs. Wireless

Mug warmers are either wired or wireless. Wired mug warmers may sound better, but wireless can be more convenient. But it is not that simple as it sounds (no pun intended).

Wired mug warmers can be plugged into a wall socket or a USB port. Models with a USB port are more convenient, as you can connect them to devices like your laptop or desktop to keep your java warm. If you’re someone who works on their desktop and simultaneously sips coffee while working, you’ll probably find these perfect for you. At the same time, models with an AC power cord are more powerful than their wireless counterparts.

It would be best to consider the cord length of your mug warmer as well. Make sure it is long enough, allowing you flexibility as to where you can place it. It sure sucks to put your mug warmer on the floor if the cord length isn’t long enough to reach the plug.

Wireless mug warmers don’t have a cord and instead rely upon periodic charging. Some mug warmers require batteries to operate. These are convenient options for those connoisseurs who like to walk and drink or want to free up their outlet space.

Temperature Range & Controls

The sweet spot for the temperature to enjoy is around 120 and 140 degrees. Most mug warmers are designed to keep the drink’s temperature within this range, so you get to enjoy your drink for the next few hours.

However, it’s important to remember that your mug warmer won’t be able to heat your coffee if it is stone cold. In order to ensure the best results, place your steamy cup of joe on a mug warmer while it’s hot, and it should sit there when you’re not sipping.

Some basic mug warmer models have only one temperature setting, while high-end ones have adjustable temperature control. If you use your warmer for different drinks, like tea or coffee, a mug warmer with a range of temperature controls will be your best bet. Some feature a neon light indicator that lets you know when the desired temperature has been reached.

Automatic shut-off

If you’re someone who keeps forgetting things, models with an automatic shut-off feature could be perfect for you. Most high-quality mug warmers offer this feature, which kicks in after a set amount of time. It also makes your mug warmer more eco-friendly. If you opt for a model without an automatic shut-off feature, ensure that you turn it off when it’s no longer in use.


Waterproofing is another factor to consider to ensure your mug warmer can withstand the occasional drips and spills. Most of them are made with waterproof elements that can be wiped down easily with a clean damp cloth if any splattering occurs.
