About This

• Semiconductor Active Cooling, Not Just a Fan: Unlike cheap fan-only coolers, K51 uses TEC semiconductor technology with a larger cooling plate. Achieves visible frost at 30°C room temperature — true cooling fan performance at a budget price.
• Large Cooling Plate for Faster Heat Dissipation: Bigger contact area means phone cooler for gaming without frame drops, lag, or thermal throttling. Keeps your hands comfortable to hold even under load.
• 3 Adjustable Gears & RGB Light Switchable: Toggle between -9 rapid-cool, -6 quiet, and 99 full-speed modes. The 3-color RGB light adds gaming atmosphere; ; a single button press turns lights off completely for distraction-free, bedroom-friendly use.
• Universal Magnetic & Clip-On Fit: Snaps directly onto MagSafe iPhone 12-16 series. For Android phones, use the included clip bracket or stick-on magnetic ring. Fits 4-7 inch devices. Bonus accessories in the box. No battery, just USB Powered.
• Plug & Play Wired via USB: Powered by any 5V/3A USB-C charger (cable included, no charger). A wired USB fan, not wireless — delivers consistent high-performance cooling without battery worries. Whisper-quiet operation won't disturb your gaming voice chat.
