The Ember Mug 2 Retails for Just $70 and Comes With Free Shipping and a Full One-Year Warranty.
If you’re the type to reheat the same cup of coffee two or three times before finally finishing it, the Ember Mug 2 could be a great upgrade for you. It’s a 10-ounce smart mug that keeps your drink warm (between 120 and 145 degrees) for up to 90 minutes on battery power, or all day when left on the charging pad. This Open Box model is currently on sale at StackSocial for $69.99 (down from $129.95), and while it’s not sealed or flawless, it’s tested like new and includes a full one-year warranty. Shipping is free within the continental US, and everything you need—mug, charging pad, and cable—is already in the box. Just pour your drink, let it do its thing (it’ll let you know via a tiny LED indicator when your brew has reached the perfect temperature), and forget about lukewarm coffee.
You can use the Ember Mug 2 right out of the box, with a default temperature of 135 degrees, but the real fun begins when you connect it to the Ember app (available for iOS and Android). You can set the temperature you want, assign custom settings for different drinks (tea, black coffee, green tea, etc.), and even change the color of the LED light to suit your mood. Plus, the mug automatically turns off when it runs out of water or hasn’t been touched for a while, which is great for those who constantly forget if they even left the mug on the charger.
You’ll have to wash it by hand (it’s not dishwasher safe), but it’s waterproof enough (IPX7) that you can rinse it or even submerge it in water if you get too carried away with the sponge. It also charges via USB-C, so you won’t have to hunt for a proprietary charger if you lose the cable. If gift-giving season is approaching or you’re just tired of babysitting a drink in the microwave, this gadget really deserves its place on your kitchen counter .
