Battery Mug – Black & Green

The porcelain Battery Mug is where ingenious science meets innovative design. This unsuspectingly conventional mug appears to be plain black until you pour in your hot beverage of choice and it responds to heat. When filled with hot liquid, a techy battery icon appears on the mug, “charging itself” according to the level of liquid in the mug. Recharge your mug then recharge your batteries with a good cuppa joe and you’re good to go!
