Heat can ruin your game, slow your stream, and drain your phone faster than it should. This TH12Ai flagship magnetic semiconductor phone cooler is built to solve that problem directly, pulling heat away from your device fast so you stay in the game, on air, and at full speed.

Snap it on magnetically, select your mode, and let it work.

Cool Your Phone By Over 32°C in High Mode

At an ambient temperature of 25 °C, this cooler delivers a cooling reduction of over 32 degrees Celsius in high mode and produces visible frosting on the cooling surface. That is not passive cooling. That is active semiconductor refrigeration pulling heat directly away from your phone's back, before throttling ever kicks in.

AI Mode That Reads and Reacts in Real Time

The built-in AI cooling mode does not just run at a fixed speed. It continuously monitors the TEC surface temperature and adjusts power output step by step.

When the temperature is between 10°C and 40°C, it runs at full power — 24W — for maximum cooling. As the surface temperature drops below 10°C, the cooler automatically reduces output by one gear for every degree drop, checking every 3 seconds, stepping down up to 10 levels to protect against overcooling. When the temperature rises back above 10°C, it increases power back up at the same rate.

The result is intelligent, self-regulating cooling that protects your phone, saves energy, and never overcorrects.

Four Modes for Every Situation

You can also control the cooler manually. Three fixed power levels give you precise control, and AI mode handles everything automatically.

Low (L1) — 6W for quiet, everyday cooling during light tasks
Mid (L2) — 12W for streaming, video calls, and moderate gaming
High (L3) — 24W for competitive gaming, long streams, and peak performance demands
AI Mode — automatic step-by-step adjustment based on real-time surface temperature

A single button switches between gears. Long-press to power on or off. A second button toggles between power display and temperature readout, and long-pressing it switches the lighting effect on or off.

A Body Built to Handle the Heat

The housing is constructed from PC and aluminum alloy for a balance of lightweight durability and efficient heat management. The cooling fins are made from forged aluminum, engineered to maximize surface area and airflow without adding unnecessary bulk.

Works With Every Phone

This cooler is compatible with all phone models. Attach it using the magnetic mount or the included clip, connect power via the Type-C interface, and it is ready to go. No adapters. No complicated setup.
