The Happiness Smart Heated Coffee Mug is a 12 oz rechargeable electric mug that keeps coffee, tea or another drink at a chosen temperature. Temperature can be set in 1°F steps. LED lights show the battery level and the temperature.
The mug is made of stainless steel with double-walled vacuum insulation, which helps hold heat and keeps the outside from getting too hot to handle. It has a scratch-resistant coating that is safe to hand wash. The mug is IPX7 rated and can be fully submerged up to 1 meter deep.
You can set the temperature with the button on the bottom of the mug or with the Happiness app. The app shows the drink's temperature and lets you customize the setting. The 4000 mAh polymer lithium battery keeps drinks hot for more than 180 minutes, and longer with the lid on. It comes with a spill-resistant lid and a charging coaster.
