Pour your favorite hot beverage into Art Lebedev’s Battery Mug and the indicator on the side will show you how hot the liquid inside is, as long as it’s above 96.8°F. As you drink it, the green indicator will show you how much is left, and if its temperature gets too cool, the green indicators will fade to black.

Art Lebedev does it again, taking something familiar and making it even better. This mug is just $28. You need this right?

Of course you do.
