If you’re someone who reheats the same cup of coffee two or three times before finally finishing it, the Ember Mug 2 might be your kind of upgrade. It’s a 10oz smart mug that keeps your drink at your preferred temperature (anywhere from 120 to 145 degrees) for up to 90 minutes on battery or all day if you leave it on its charging coaster. This Open Box unit is on sale for $69.99 right now on StackSocial (down from $129.95), and while it isn’t sealed and pristine, it’s been verified to be in new condition and includes a full 1-year warranty. It ships free to the contiguous U.S., and everything you need is in the box—the mug, charging coaster, and cable. Just pour your drink, let it do its thing (it lets you know via a tiny LED light when your drink has hit your perfect temperature), and forget about lukewarm coffee.
You can use the Ember Mug 2 straight out of the box with its default 135-degree setting, but the real fun starts when you pair it with the Ember app (available on iOS and Android). You can dial in a specific temperature, assign custom presets for different drinks (tea, black coffee, green tea, etc.), and even change the color of the LED to match your vibe. It also shuts off on its own when it’s empty or hasn’t been touched in a while, which is great for people who forget everything, including whether they left their mug on the charger.
You’ll need to hand-wash it (it’s not dishwasher safe), but it’s water-resistant enough (IPX7) to rinse or even submerge if you get carried away with the sponge. It also charges via USB-C, so you’re not stuck hunting for a proprietary charger if you misplace the cable. If gifting season is coming up or if you’re just tired of babysitting your drink with a microwave, this is one of those gadgets that actually earns its place on the counter .
