Rapid, reliable cooling: Semiconductor cooling technology delivers a fast temperature drop with active heat absorption and efficient thermal management. This reduces device heat build-up, keeps your phone comfortable to hold, and helps maintain long-term device performance. Tool-free magnetic mount: A robust magnetic quick-mount design lets you attach and remove the cooler quickly without tools. The mount holds securely to most major phone models while allowing easy access to buttons and ports during use. Smart temperature control and display: The built-in intelligent display provides real-time temperature readings and automatically adjusts cooling power. This continuous monitoring helps prevent condensation and ensures the cooler runs only as hard as needed. Detachable battery and external power support: The removable battery system prevents your phone from being drained by the cooler and lets you swap batteries for uninterrupted use. You can also connect an auxiliary external battery to extend runtime when needed. Key benefits — why you need it Keeps performance stable during intensive use (gaming, streaming, long calls) by preventing thermal throttling. Improves user comfort by maintaining a cooler surface temperature during prolonged handling. Protects device health by managing heat more effectively, which can reduce wear on internal components. Compatibility and operation Magnetic quick-mount fits securely on most major smartphone models and is designed for easy on/off placement. Intelligent display gives instant feedback so you can monitor and trust the cooler’s performance. Detachable battery removes the risk of draining your phone and enables extended sessions via external power. Practical use scenarios Mobile gaming: Stay cooler during extended play sessions; the system reduces heat-related slowdowns and keeps the phone comfortable to hold. Live streaming or video recording: Maintain steady device temperatures for longer recording times without worrying about automatic shutdowns. Navigation and outdoors use: Keep your phone running reliably in hot conditions and swap batteries or connect to an external power bank for long trips. What makes this cooler stand out Semiconductor-based active cooling for faster, more controlled temperature reduction than passive options. Intelligent, feedback-driven operation that balances cooling performance with condensation prevention. A user-friendly magnetic mount and a removable battery strategy that avoids draining your phone and supports extended use. Note: Designed to work with most major phone models using the included magnetic mount; performance is managed automatically via the built-in display and control system.
