The ANSTY MR-01 magnetic phone cooler and external battery are designed for smartphone owners who want to maintain their device's performance at a high level. A powerful cooling system effectively reduces heat generation during gaming, video recording, or extended device use. The magnetic mounting system ensures a secure hold, and the built-in 3000 mAh battery provides additional charging when needed—a larger capacity than the MR-02, extending battery life. A digital LED display allows you to easily monitor the cooling time and status.
