If you’re prone to forgetting that you made a hot drink and don’t want to reheat it in the microwave, then we’ve found the best mug warmers to keep your cup steaming hot at your desk. Let's face it, we can all do much better about being energy efficient. Even the best kettle burns through electricity, so a low wattage mug warmer is a good money-saving investment in the long-run.
Whether a barista-style latte from a coffee machine or a homely cup of tea, we’re bound to be sipping on something warm any time of the day. Almost like a ritual, a hot drink wakes us up in the morning, sees us throughout the tough, busy working day and accompanies our wind-down before bed. A mug warmer keeps your hot drink at an optimal temperature for longer, ensuring it stays warm and enjoyable.

A mug warmer is a convenient device designed to keep your cup hot and drink warm so it doesn't cool down so quickly. This way, it keeps that lovely hot temperature - that your kettle worked so hard for - a bit longer. Mug warmers are designed as table-top gadgets with small heating coils inside that’ll heat up and act as a mini hotplate. You can rest your mug on top, and it’ll act like a heated coaster. Luckily, ceramic, metal, glass and enamel are all safe to be used on a mug warmer to keep your drink hot.
It might seem like this helpful gadget is just a cheesy gimmick, but be prepared to stand corrected in a moment’s time. Most coffee gadgets – like a milk frother – will help you out immensely and improve your morning cup. We've picked out the best available to buy.

GARMEE's mug warmer is fantastic for cramped and cluttered desk users, taking up very little space during use.
Customer review: "Got this for Christmas as I never seem to drink a full cup of tea at work. This keeps your drink at a good temperature for hours if necessary. I tend to use the high mode, but there are three so plenty to choose from. Just switch it on, select the temperature and it will stay on for eight hours if you don't switch it off. You do need a reasonably flat-bottomed mug but I've not had any problems with it. Just watch out for little fingers at home as the warming plate does get very hot."

This plug-in Duokon Electric Cup Warmer Pad is made of high-quality aluminium and a heat-resistant glass panel, so it looks super sleek. It's waterproof, so you don't need to worry about safety with any accidental spillages and can be used with glass, ceramic, metal or plastic mugs. The smart touch switch regulation is easy to operate, and you can switch between low-temperature heating (40-50 degrees Celsius) and high-temperature heating (55-60 degrees Celsius). It'll shut off automatically after eight hours, by which point we hope you'd have finished your cuppa anyway.

With three temperature settings to choose from, you can really get your perfect hot drink with this GREATCHI Mug Warmer. It'll keep your drink warm for a few hours, and there's a shut-off function after four hours for safety. The glass panel top is waterproof, fireproof and a decent size, making it suitable for certain cups, mugs, carafes and bowls (you can stop that lunchtime soup from going cold too!) It'll remember your temperature preferences, too.
**Customer review: "**I’ve had this on my wish list for a while not but only recently purchased and done because I work from home dealing with calls. By the time I’ve made a cuppa and taken a call, the brew is cold. With this device, I’m able to go for two-three hours without the coffee being affected. Still perfectly hot and sometimes even hotter than I prefer it so have to turn it down (even without a flat bottom cup)."

We recommend the Ember New Temperature Control Smart Mug 2. It's so much more than just a clever coaster, it's a smart mug as well. The temperature control, quality material and sleek design make Ember our cup of tea. While not all of us will want to embrace the app, it's a cool feature to play with too.
FAQs
What Should I Be Looking For?
Budget – How much are you willing to spend? We’re no strangers to a bargain at A Modern Kitchen, and finding a budget coffee machine for your kitchen is something we love to do. For our round-up, we’ve made sure to include various mug warmers at different price points.
Power – If you’re working from a desk, then a USB-powered mug warmer would be super convenient – as you can heat your coffee up with your laptop. Some on our list are even wireless and require charging. This is down to when and where you’d use it.
Cable Length – As some are wireless, so you won’t need to worry about this one. However, if you are in need of a power source for your chosen mug warmer, we recommend measuring the distance between your favourite coffee spot and an outlet – so there’s no tricky cable wrestling.
Dimensions – Check the size as you want your preferred coffee cup to fit your mug warmer.
Temperature – This can sometimes be altered with mug warmers. Here, you can choose between different settings, depending on your preferences. Some like it hot, whereas some just prefer it lukewarm. You’ll find that the temperature range will differ between gadgets.
Heating Time – Luckily, our picks vary, whether you need it heated for 30 minutes or throughout the day, we’ve got you covered. A mug warmer beats tipping your precious cuppa down the sink or attempting to sip through microwave-warmed tea.
Are mug warmers safe?
Most mug warmers you can buy are safe and are designed to be tea or coffee-proof. However, for peace of mind, it's worth choosing a mug warmer with built-in safety features.
These safety features can come in all forms, including an automatic shut-off after a set period of time or gravity detection so it'll switch off when not in use. All helpful and will help to prevent any incidents.
However, not all mug warmers come equipped with such features. So, if this isn't an option, make sure to be wary to turn it off when not in use – to save any burnt fingers or scorched dining tables.
Are mug warmers worth it?
If you’re staying indoors for work and your reusable coffee cup isn’t seeing much use, a mug warmer could be a good option for you. Or they could make a great gift for a forgetful loved one.
