Phone coolers

Phone coolers

— a compact phone cooler helps cool down the body in the processor and battery area to prevent the smartphone from overheating and maintain stable performance longer. Most often, it's an attachable module with a fan or thermo-element (sometimes with a Peltier effect), which is attached with a clip, magnet, or through a compatible case, dissipating heat outside and reducing throttling during games and video recording. Unlike a "cooling" case or simple ventilation without active airflow, a cooler has a significant impact on temperature but adds bulk, noise, and requires power (usually USB). Usage examples: long gaming sessions, phone streaming, 4K/60 shooting in the heat, car navigation under the sun when the smartphone often overheats and reduces screen brightness.
