What is a Mug Warmer?

A mug warmer is a device that works similar to the way electric kettles do. It has heating coils and elements that gradually heat and maintain a steady temperature. Therefore, not only does it warm up your coffee after it has cooled down some, but it keeps it warm for hours. 

Most mug warmers are electric, allowing you to plug them into a wall socket or a USB port. They are also flat and disc-like in shape, making a platform for you to place your cup on for it to be heated. 

Why Do I Need a Mug Warmer? 

First off, because they’re simple yet nifty little tools that won’t only make you feel fancy when you use them, but will also make sipping your coffee a lot more relaxed. And (if we’re being honest here) they’re just plain fun. 

However, chances are, a nice mug warmer will make sipping your hot coffee a more enjoyable experience. If you’re a person who likes to slowly sip their coffee as they get ready in the mornings, or if you need a way to keep your coffee warm while working at the office, a good mug warmer may just become your new best friend. 

Mug warmers allow you to go about your business without having to worry about your cup of coffee turning cold. Furthermore, they give you much more freedom and permission to get distracted from drinking your coffee without losing your coffee’s temperature or freshness. 

Different Kinds of Warmers

There are many different kinds of mug warmers out there for you to compare and contrast. The great news with this is that there’s likely to be a style that fits everything you need in a mug warmer. Here are just a few varieties for you to consider.

Before You Buy…

For any avid coffee lover, purchasing a mug warmer can be both an exciting, but also slightly overwhelming experience. Due to this, we recommend you keep these following characteristics in mind when deciding which mug warmer “style” would be the best fit for you. 


The material that your warmer is made out of is automatically going to define how well it is going to perform. Obviously, warmers made of plastic and lower quality materials aren’t going to last you as long as warmers made out of solid, sturdier material like stainless steel. 

Likewise, the material of the warmer will also determine how well it does its job. Stainless steel warmers will heat your coffee better because metal is a better conductor of heat in comparison to materials like glass or plastic. 


Depending on how much you’d like to splurge, you can either purchase a warmer that gets the basic job of warming done, or you can purchase one that does a multitude of things. However, our best advice is to get a machine that works well without breaking the bank. Thankfully, there are many mug warmers out there that typically range anywhere from $10-$40 that perform well and get the job done every time. 


Since mug warmers are mainly designed to maintain efficiency, they should be compact to maintain physical efficiency. If you’re trying to warm your coffee without having to pay too much attention to it, you’ll probably want to be able to accomplish this in an area that doesn’t take up too much space. 


Wanting to take your warming capabilities on the road? Then you’ll need to take portability into account. You can easily purchase warmers that are compact enough to be packed in a suitcase or a backpack, but there are options out there to not only take your warmers on the go, but use them in the middle of travel as well. 

Temperature Fluctuation

The fluctuation of temperature is also important to see how quickly and how effectively your machine is able to perform. Most warmers function but increasing and decreasing their temperature in intervals, and this controls how well your coffee is heated. Likewise, different warmers offer different temperatures and how effectively those temperatures can be reached. 

Cord Length

If you’re considering purchasing a mug warmer, you should try and make sure that the length of the cord will suffice in the area where you plan to store it. Cord lengths vary from inches to several feet long, and some warmers may not even require electrical cords at all. 

Frequently Asked Questions (FAQ)

Even if you’ve taken all of the characteristics you need to consider before purchasing a mug warmer into account beforehand, you can still have some remaining questions. Here are some answers to some of the most common questions that you may be asking yourself.

How hot do mug warmers get?

When it comes to brewing temperatures, the ideal range Is around 195-205 degrees F. For drinking temperature, the sweet spot is around 136 degrees F. This is important to keep in mind when searching for warmers because some offer temperatures significantly cooler and hotter than this median temperature. 

How long do mug warmers stay warm for?

Just as warmers offer a variety of temperature ranges, they also have different warming times and automatic shut-off times. Some shut off after an hour of heating, and others shut off after 4-5 hours. Really it just depends on how long you think you’ll be sipping on one (or multiple) cups of coffee throughout the day. 

What size cups do mug warmers hold? 

Most mug warmers have enough area space to support the size of an average coffee mug. Pretty much any regular looking coffee mug will fit just fine on the surface of the warmer, the average diameter of a mug base being around 80 mm. Though some mugs may be smaller or larger than the average, it shouldn’t really be that much of a hassle to accommodate. 

Wrapping Up

At the end of the day, with so many options out there to choose from, the best way to decide which mug warmer would work best for you is to consider what you need out of your mug warmer. Do you care more about automatic warming temperatures or selecting your own temperature? Questions like this are going to determine which option will fit best for your needs. 

So do some research, look around, and you’ll quickly be able to find one that best suits you. 

Happy caffeinating!
