Whether you take your time drinking your morning coffee or get pulled in a million directions before you can even take your first sip, one thing is true: Hot coffee has a very short lifespan. For those who would rather not depend on the microwave every time their coffee turns lukewarm or cold, I went in search of the best coffee mugs to keep coffee hot. Whether you prefer a customizable electric cup warmer or a portable insulated style, these picks are customer-approved options.

If you sit at a desk most of the day or prefer not to drink your coffee in a single sitting, a coffee mug with an electric warmer is a good investment. Similar to a hot plate, the electric warmer does double duty as a coaster and maintains the temperature of your mug’s contents when it’s in place. Certain models allow you to set the temperature to your preference, whether you like your coffee warm or steaming hot.

If you’re looking for a portable, standalone mug to keep your coffee hot, pick one with double-wall construction. The vacuum-sealed layer of air prevents heat from escaping and insulates your coffee from cold ambient air for longer. Also, pay mind the size of the coffee mug. No matter how hot your coffee is, if the mug isn't big enough for your needs, you'll end up having to get up and refill it.

No matter what your budget or aesthetic preferences are, these are the best coffee mugs to keep coffee hot.

1. The Overall Best: CORSORI Coffee Mug Warmer & Mug Set

Desk-dwellers and slow-sippers will love this two-piece set from Cosori. It includes a 17-ounce stainless steel mug and a heated base that will keep your coffee or other hot beverage at a consistent temperature for hours. Three touch-control buttons allow you to power the heater on or off, and adjust the temperature between 77 and 158 degrees Fahrenheit to your ideal sipping preference. The mug has a cool-touch handle and a slip-resistant silicone sleeve, as well as a lid to keep the contents warm, even if you bring the mug into a different room.

According to one reviewer: "I’ve had several different coffee warmers and this one is hands down the BEST! I’m able to keep my cup of coffee nice and hot for a very long time! I put hot water in the mug to “pre heat” it for a minute then brew my cup of coffee. I can then take it upstairs and put it on the warmer base and enjoy my cup of coffee for as long as I want without it getting cold. Anyone who is tired of their coffee getting cold so fast should absolutely get this item. It’s fantastic!”

2. The Best Value: SUNWILL Coffee Mug With Handle

If you’re looking to sip coffee away from an outlet, your next best choice is a double-wall vacuum-sealed mug like this one from Sunwill. The 14-ounce mug is made of lightweight but durable and rust-proof stainless steel, and will keep your drink hot for more than three hours. The included BPA-free clear lid fits snugly on the mug, and has a sliding opening so you don’t need to remove it to take a sip. The Sunwill comes in a range of fun colors, and if you like to drink iced coffee in the warmer months, the double-wall construction will keep iced drinks cold for up to nine hours, as well.

According to one reviewer: "I bought this mug because I rarely get to finish my cup of coffee in one sitting at work. From the minute I am in the door, I am going. I used to make a cup and have to end up reheating three or four times [...] This mug keeps my coffee hot (not warm) for hours. My cup lasts me all day, and by the time I take my last sip at 2:30, it's not piping hot, but it is still a warm cup of coffee.”

3. The Best Thermos: Zojirushi Stainless Steel Vacuum Insulated Mug

Zojirushi’s stainless steel vacuum-insulated travel mug has one of the best designs when it comes to temperature retention, and will keep coffee hot for up to six hours. In addition to the double-wall construction, the mug’s lid flips open so you can pour or sip from the mug without opening it. The lid clicks closed and has a lock to keep heat and spills contained. The tall, slender design of the Zojirushi fits in most car cup holders, and also takes up minimal space if you want to slip it in a travel bag or a purse. It is available in 12, 16, or 20 ounces, and comes in a variety of neutral and bright colors. It boasts an overall 4.8 star rating from over 28,000 Amazon shoppers, which is pretty impressive.

According to one reviewer: "It is winter here, and its cold. This thermos keeps the coffee hot in those conditions for 10++ hours. I went one day from 6am when I got the coffee to about 10pm at night before I noticed it being "lukewarm".”

4. The Editor’s Pick: Ember Temperature Control Smart Mug

If you’re very serious about keeping your coffee hot all day and like the look of a traditional ceramic mug, this temperature-control smart mug from Ember is an excellent – albeit pricey – option. The stainless steel mug conducts heat efficiently, and has matte black ceramic coating, giving it a classic look. The key difference between the Ember and the overall best (besides price), is that the heat source comes from inside this mug as opposed to the base, allowing you to bring it with you anywhere and still control the temperature. The saucer acts as a charging base for the mug, and the mug can last for an hour on a single charge. You can control the temperature of this mug from the Ember app, which even comes with pre-programmed temperatures for popular drinks like lattes, espresso, and tea, and has built-in timers you can set for how long you want to keep your drink hot. The app also comes with included recipes, and you can even sync it to your health app on your phone to track your caffeine intake against your other vitals.

Editor's note: After years of reheating cold coffee in my microwave, I invested in this smart mug. I love that you can control the temperature from an app, so I can bring it with me to another room and still control what temperature it is. Amy Biggart

5. The Best Double-Walled Glass Mug: Eparé Glass Coffee Mug

Whether you want to make photo-worthy layered specialty lattes or simply love a see-through mug, these double-walled mugs will keep your coffee hot while offering a sleek, modern look. Made from durable Borosilicate glass, each mug has a 12-ounce capacity, and can be run through the dishwasher for easy cleaning. These mugs are resistant to condensation, which is a great feature if you like to switch between hot and iced coffee drinks, and they produce a cool optical illusion that makes it look like your drink is floating inside of the glass. At just $25 for a pack of two, they’re a great value, too.

According to one reviewer: “I’ve been using my mugs everyday since I purchased them. I absolutely love them. I’ve put them in the microwave and dishwasher. They are lightweight, but very durable. I love being able to see my drink, whether it’s coffee or tea. The double insulated glass keeps the hot drink cool to the touch.”

6. A To-Go Mug With A Near-Perfect Rating On Amazon: YETI Rambler 20 Oz.

If you want to upgrade your to-go mug, get this YETI Rambler tumbler, which boasts a near-perfect 4.8-star overall rating on Amazon. It’s made from stainless steel, and has double-walled vacuum insulation that keeps hot beverages hot and cold beverages cold for hours on end. The sip lid also has a magnetic lock, which does not prevent leaks or spills, but will help to keep your coffee hotter for longer if you snap it closed when you’re not actively drinking. Despite the large 20-ounce capacity, its slim design means it fits in most standard car cup holders, which is a huge plus.

Editor’s Note: I’m obsessed with my YETI rambler mug, especially for long car rides. I’m a very slow coffee and tea drinker, but this to-go mug keeps my coffee hot for hours. It also just looks really sleek and nice. I have it in both the navy and maroon colors, and I love them both! — Carina Finn

7. A Set Of Insulated Mugs With Built-In Coasters: DOWAN Insulated Coffee Mug

These 15-ounces insulated ceramic mugs not only look beautiful, but they also have so many useful features. The ceramic body is insulated to keep your beverage warmer for longer, especially when paired with the removable sip lid, which can help to retain your drink’s heat. The bottoms, which can also be easily removed, are made of cork, so in addition to boosting insulation, they’ll also protect your tables from scuffs and scratches. They come in four neutral colors, have thousands of fans on Amazon, and should be hand-washed to keep them looking their best.

According to one reviewer: “I have been searching for something like this for A LONG time. I make myself a fancy-ish coffee/tea every morning. I am someone who, when drinking a hot beverage... actually likes it to stay hot. So I typically drank out of a "travel mug" while at home. But this is so much more... satisfying. The ceramic is great, as is the rich color, and the cork is not only aesthetic but functional (no ring marks on your wooden coffee table or nightstand). In fact, you could say that about the whole mug. Aesthetic and functional. My favorite combination for all things in life.”
