There's nothing like a sit down with a cuppa to recharge those batteries and this is the perfect mug with which to do so. The mug features battery design detailing – including a copper coloured rim displaying the sign. The mug’s body shows a recharge level which increases and decreases upon contact with hot liquid. When full with a nice cuppa, the levels fill up to 100% leaving you and the battery mug full and happy. Features Great novelty gift. Heat Change effect when hot liquid is poured in. Not dishwasher or microwave safe.
