Staring at that cup of coffee you forgot about which is now undrinkably cool? This is the 21st century, friends — you don’t have to drink cold coffee. All you need is to starting using a smart mug.

The best smart mugs allow you to keep your drink at the precise temperature you prefer, and will keep your coffee or tea at, say, 131 degrees exactly throughout the rest of your afternoon meetings (yes, all of them). They charge easily via a USB cable and keep warm thanks to a coaster-style charging plate or built-in heating function.

When adding a smart mug to your cupboard, all you really need to think about is how effectively it regulates temperature, battery life, and whether you’re going to want to travel with it or not.

What Are the Best Smart Mugs?

The devil is in the details when it comes to smart mugs, so you need something that suits your tastes and which is highly-customizable and programmable.

Temperature Regulation: We love mugs that not only keep your drink warm throughout the day, but which can also cool your coffee or tea down to a level that’s comfortable to drink right away. Most mugs allow you to set your temperature settings, either directly on the mug or with a smart phone app.

Battery Life: Depending on where and how your mug is charged, the battery life will change. Many manufacturers claim around eight hours of battery life, but at the very least, the best smart mugs should at least be able to continually maintain temperature for several hours before needing to be recharged.

Travel vs. Standard Mug: Travel mugs are great because they are well, equipped for travel. They also tend to have larger coffee capacities. On the other hand, they can be a little less pleasurable to drink from and are lacking in the looks department. A standard mug replicates a classic coffee mug that you would be proud to display on your counter or desk. The best smart mug for you largely comes down to personal preference, but there are smart options for both… pun intended.

1. Ember Temperature Control Smart Mug

A smart mug shaped like a mug, the Ember temperature control coffee cup includes all the customization and operation features we’ve come to expect from any smart home object short of voice activation (though we think you’d look a little silly barking orders at your coffee mug in any case).

Using your phone, you can set your preferred temperature, customize presets, and even receive notifications. The LED display on the base of the mug lets you know when it’s heating up, cooling down, or just right, and the included charger doubles as a coaster. We’re in love, basically.

2. Cauldryn Coffee Smart Mug

This travel mug is a little less sleek than the Ember, but still includes customizable temperature control, a smart phone app, and LED display. Where it stands out is capacity and battery life. Because it’s a portable mug, the battery keeps java (or hot chocolate or tea) hot all day, and can contain a lot more liquid than the desktop model.

3. BURNOUT Temperature Regulating Mug

We’ve talked about keeping your coffee hot, but what about cooling it down? This Burnout smart mug’s claim to fame is the “instant drinkability” feature, which cools liquid down to the ideal temperature in minutes. Say so long to that burnt tongue that ruins your ability to taste anything for the rest of the day because you tried to sip your coffee too early.

Another fun feature to this mug is the high-tech/low-tech battery-free operation. Instead, Burnout uses the thermal energy sucked from the beverage’s heat to power itself.
