Full Product Description

Say Goodbye to Overheating and Dropped Frames

Nothing ruins a flawless gaming streak or a viral live stream faster than a thermally throttled smartphone. When your device overheats, the processor slows down, resulting in frustrating lag and drained batteries. The K31 Magnetic Phone Cooler is engineered to permanently solve this problem. Delivering a stable 119.8Hz frame rate during intense sessions, it ensures you never lose a match to hardware limitations again.

 

AI-Powered Precision Cooling

Not all cooling is created equal. While standard fans just push warm air around, the K31 acts as a professional temperature manager. Powered by a built-in AI Intelligent Chip, it precisely senses your phone's real-time temperature and dynamically adjusts its cooling power. This guarantees your device stays within an optimal operating range without over-freezing, saving energy and maximizing component lifespan.

 

Universal Magnetic Fit for Seamless Play

Designed with an ultra-strong magnetic grip, the K31 snaps perfectly onto the "heart area" of MagSafe-compatible iPhones. No clips, no bulky clamps—just pure ergonomic freedom that won't interfere with your grip. Don't have a MagSafe phone? No problem. The included premium magnetic sheet ensures seamless compatibility with any Android device.

FAQ Section

Q. Does this cooler need to be plugged in to work?
A. Yes. To power the 15W high-performance semiconductor, the K31 must be plugged into a power source via the included Type-C cable. For the best freezing effect, we recommend using a charging brick with an output of 5V/3A or higher.

Q. Will it fit my Android smartphone?
A. Absolutely! While it snaps natively onto MagSafe iPhones, the package includes a high-quality magnetic sheet that attaches to the back of any Android phone, allowing for a perfectly secure magnetic grip.

Q. Will the rapid cooling cause water condensation inside my phone?
A. The K31 is equipped with AI Intelligent Temperature Control precisely to prevent this. By monitoring your phone's actual temperature, it adjusts its power to maintain a stable environment, drastically reducing the risk of harmful condensation compared to "always-on" maximum coolers.
