This portable electric car water keep warmer coffee mug is a 300ml stainless steel car kettle built for keeping drinks warm on the road. It plugs into a 12V car cigarette lighter socket and fits most cup holders, making it a simple option for commuting, road trips, office use, or outdoor breaks. Compared to a standard travel mug, it connects to your vehicle for continued warming while you drive.

• 300ml capacity, about the size of a compact personal drink flask
• Stainless steel outer wall and inner liner with mirror-polished interior
• 12V car power cord with cigarette lighter plug for vehicle use
• Fits most car cup holders for easier travel storage
• Food-grade rubber sealing ring helps improve leak resistance and hygiene
• Portable side handle with rubber grip for easier lifting

The bowl-shaped lid makes pouring water in easier, and the sealed design helps retain heat longer during everyday travel. Unlike a basic insulated mug that only holds existing heat, this car kettle is designed to stay connected in your vehicle for ongoing warmth. The stainless steel body supports durability for repeated use, while the high-spec car power cord is built for longer service life. Use it for coffee, tea, or hot water during long drives, camping stops, delivery routes, or desk work when you want a compact travel warmer without carrying full-size portable coffee gear.
