Heating Sleeve Reusable Coffee Warmer with Portable USB Fast Charging Heats Cups

- Not Your Typical Coffee Mug Warmer Set - Many coffee warmers require a heated coffee mug and a coffee heating pad or base that is plugged into a wall socket. This means you always must use the same cup for your heated mug of coffee, and you always need to be close to an electrical socket for the coffee heating pad. Our reusable heated sleeve sets you free and provides you with the flexibility to always keep a heated cup of your favorite drinks close and ready to go. - Innovative Safe Heating Technology - Many mug warmer sets require an electrical outlet and use higher voltage. Our coffee mug warmer and hot drink sleeve holder uses Graphene Rapid Heating Technology. This ensures that your heated drink will stay at a specified temperature around 130°F for a long period of time when connected. This is achieved through using safe low voltage USB port technology. (Note: Please use a power plug above 5V2A to charge to maximize performance) - Uniquely Designed - Many heated coffee mugs are just a single mug. It may not be convenient to always use the same mug or cup all the time. Our product has Velcro on both sides. It’s flat and flexible design enables it to fit around most mugs and cups tightly. This makes it convenient for changing and using different cups. Our heating technology is designed to be powered by USB ports which are found in cars, most office spaces, airports, planes, hotels, portable power banks, etc.
