You might think you're looking at a Thermos, but not quite. The Yecup is a connected drinking vessel with a 10,000mAh battery and enough tech to heat up or cool down the liquids it holds, and keep them there all day. If it senses the temperature deviating from what you've set, it'll fire up its mechanism and bring it back. It uses Bluetooth to connect to your smartphone, through which you can make all the adjustments you want. Left in the morning with a hot coffee but suddenly realized you'd rather have an iced one? No problem. And of course, when you're carrying a large battery around, you can use it for other things, like charging your phone or other electronics. The Yecup is made from stainless steel, and is easily washable, though it's recommended not to stick it in the dishwasher. The 12oz. cup is fully funded on IndieGogo, and will cost you a $125 pledge.
