The Best Coffee Mug Warmer (Self Heating, Battery, Auto, Etc)

Listen, I love coffee too. I work from home and I drink it all – day – long… the only problem? It cools down way before I can finish enjoying it!

If you take an hour or more to finish a cup of coffee, you probably know how frustrating it can be to constantly have to take trips to the microwave to reheat your beverage. Your cup of coffee will only stay at the optimal temperature for a short while before it needs to be reheated.

This is especially true when working from home. With the screen glaring at you and your furry coworker making cute little stunts around your workspace, getting some work done could be quite a hassle. A good cup of coffee makes all the difference. You take one sip, and you’re back to work. But before you know it, seconds have rolled into minutes, and your second or the third sip is a total letdown. So you’ve been there too eh?

Fortunately, you can avoid all this drama by getting a coffee mug warmer. I’m personally trying this one out now which I got from Amazon and so far I love it! Coffee warmers ideally let you take control of the temperature of your hot liquid companion so that you can take all the time you need to finish it. The good thing about them is that they come with fun, quirky, and helpful features, and you can be sure that you will find one that suits your lifestyle and needs.

Mine for instance has two-in-one functionality; its main job is to keep my coffee warm and the other a wireless charger for my phone. Also, what I like about this one is that it is a USB self-heating mug! You can’t see the USB cable in the back, but it’s a USB-C that I can plug directly into my iMac.

In this post, we have put together some of the best coffee mug warmers you can find in the market today. But first, let’s see what you want to look for when choosing the best coffee mug warmer to suit your needs.

How to Choose the Best Coffee Mug Warmer?

Coffee mug warmers generally work similarly to electric hot water kettles. They feature heating coils that heat up your beverage and keep it at your desired temperature. In most cases, they are compact, with a plate-like (or disc-like) design that takes minimal footprint. This means you can place them on your work desk without much hassle.

Ideally, the best coffee mug warmer should:

  • Let you enjoy your hot beverage of choice for as long as you need
  • Be portable and compact, allowing you to enjoy hot drinks on the go
  • Look cool or stylish on your desk

It’s also a great idea to know the features of the mug warmers you might be considering to know whether it’s exactly what you’re looking for. The following is a checklist of factors you want to keep in mind when choosing a coffee warmer:

Adjustable Temperature

Everyone has a way they like their coffee. Some like to play it safe or simply prefer it warm, while others want a piping hot drink. So, you want to account for exactly how you prefer your coffee when picking a mug warmer.

Some warmers will only warm your mug to a constant temperature, while others will give you several temperature settings to choose from. In most cases, a dual temperature option will be good enough. However, there are many warmers that give you a much wider control over the temperature you want.

Length of the Cord

Generally speaking, some of the best coffee mug warmers you’ll find are the corded ones. As such, you can’t really overlook the length of the cord. Getting the cord length right will depend on you knowing exactly where you want to place it most of the time. If your workspace is close to a power outlet, choosing a unit with a short to medium-length power cord will be great. It will look cleaner and less weird too.

Still, your safe bet would be still getting a unit with a long cord. This ensures more movability and avoids making you feel like your cup warmer is on a leash. Alternatively, you could go for a battery-operated or USB-powered coffee mug warmer. This will be ideal if you like moving around with your mug, or are looking for a portable solution.

Durability and Construction

The material of construction will call the shots when it comes to the durability of your device. Stainless steel units are great – they are easy to clean and are super durable. A tempered glass material will do the trick as well. However, you want to avoid plastic and choose such materials. It’s also important to look for water resistance and dust-proofing in the body construction. You want a mug warmer that can survive multiple spills.

Safety Features

Ideally, a great coffee mug warmer should have features like Auto-shut-off in place. This ensures that your device can turn itself off even after you’ve forgotten about it. Nearly all of our best coffee warmers for 2020 come equipped with this feature.


Aesthetics aren’t always important when choosing electronic devices, however, for coffee warmers, it’s a bit different. A well-designed coffee mug warmer that’s easy on the eyes will make your countertop or desk look good. Coffee mugs reflect our taste and personality, so should their warmers!


Of course, you will also want to consider how much you’re paying for the mug warmer. As you will soon find out, these devices come at a wide variety of prices. Plus, the cheapest one isn’t guaranteed to give you good service, and it might not be worth it to break the bank for a mug warmer.

Your best bet is to choose a quality coffee warmer that has a reasonable price point while delivering on the essential features as discussed above.
