K38 Mobile Cooler

K38 Mobile Cooler (often listed as the K38 Magnetic / Back-Clip Phone Cooler) is a popular semiconductor-based gaming radiator designed to prevent smartphones from overheating during heavy gaming, live streaming, or intensive multitasking.

Key Features & Specifications

• Semiconductor Cooling (TEC Technology): Uses a Peltier cooling plate combined with a high-speed turbo fan to achieve rapid "fast-icing" temperature drops, pulling heat away from the phone's processor.

• 2-in-1 Mounting System: Features a versatile design that supports both magnetic attachment (compatible with MagSafe or magnetic rings) and a back-clip mount, making it universally compatible with almost all iOS and Android smartphones and tablets.

• Adjustable Fan Speeds: Typically includes multiple fan speed settings (such as 3 adjustable levels) so you can balance cooling performance and noise levels.

• RGB Gaming Lighting: Built-in dynamic RGB lighting effects to match typical gaming setups, often with options to toggle the lights on or off.

• Power & Connectivity: Powered via a standard USB Type-C plug-and-play interface (generally requiring a 5V/2A or up to 15W power source for optimal semiconductor chilling).

• Lightweight & Compact: Weighing around 70g to 100g, it is compact enough not to strain your wrists during long gaming sessions.

Performance Benefits

• Reduces Thermal Throttling: Keeps device temperatures low to stabilize frame rates (FPS drops) and eliminate touch lag during games like PUBG Mobile, Free Fire, Call of Duty: Mobile, or Genshin Impact.

• Extends Battery Life: Lower operating temperatures help preserve overall long-term battery health by preventing excessive heat accumulation.
