Ember’s smallest self-heating mug is on sale for just $33

We’ve been fans of Ember’s temperature-controlled mugs for years, though given the price tag, we admit that they’re somewhat of a luxury purchase. Thankfully, if you’ve been looking for a more affordable option, Woot is selling the Ember Cup in black for $32.99 ($67 off) with a 90-day warranty through November 7th. You can potentially save even more as part of Woot’s larger Home and Kitchen Sale, which lets you save an additional $20 off orders of $100 or more when you use code COOK at checkout. Ember Cup (six-ounce) Where to Buy: $99.99 $32.99 at Woot Granted, six ounces isn’t much, but the smaller, handle-free cup is well-suited for cappuccinos, cortados, flat whites, and other espresso-based drinks. It’s also a perfectly fine option if you don’t mind refilling your cup of coffee, cocoa, or tea throughout the day. I’m actually tempted to pick one up myself at this price, especially since I’ve been trying (with varying degrees of success) to cut back on coffee. Like Ember’s larger mugs, the smart cup lets you choose and set your drinking temperature between 120 and 145 degrees Fahrenheit using a companion app, then remembers your setting for future drinks. It can then maintain that temperature for up to 95 minutes on a charge, up to four hours with a lid, or even all day if you leave it on the included charging dock. The cup also automatically enters sleep mode after two hours of inactivity to conserve power. Just keep in mind that, despite its IPX7 water-resistance rating, the cup is hand-wash only.
