The Cauldryn DC Power Base will turn your Cauldryn Smart Mug into the ultimate travel companion. It attaches to your existing Cauldryn Smart Mug in place of the portable battery so that you can keep a steady supply of power from your vehicle to your travel mug while you drive. The DC Power Base plugs into 12V or 24V power sources such as an auxiliary power outlet in a car or boat so you can take it on adventures on land， lake， and sea. This unit’s base is more narrow than the standard battery base to fit the specifications of standard sized vehicle cup holders. Whether you’re on a fun road trip or long work commute， the DC Power Base will keep your beverage hot while you drive to your destination.
