"I play competitive mobile shooters for hours. My phone used to dim its screen and throttle down to 40 FPS after 20 minutes. With CoolyFone, it stays locked at 120 FPS and the phone stays chilled to the touch."

Marcus Vance

"I livestream outdoor content in warm weather where iPhones constantly freeze up with high temperature warnings. CoolyFone snaps magnetically onto my phone and keeps it cold all day. Absolute essential gear."

David Reynolds

Streamer • Miami, FL

"The digital temperature screen is unbelievable. You can literally watch the temperature counter drop from 102°F down to 62°F in under a minute. The fan is super quiet and the RGB looks sleek."

CoolyFone uses active thermoelectric semiconductor refrigeration (Peltier effect) paired with a high-speed fan and aluminum heatsink. Rather than merely blowing air, it produces an actively cold surface that pulls heat directly from your phone's processor.

Yes! CoolyFone features integrated magnets that snap directly to MagSafe iPhones (iPhone 12 through 16 series). For Android smartphones or non-magnetic cases, use the included detachable clip designed to fit devices 67mm to 88mm wide.

To keep the cooler ultra-lightweight and prevent heavy battery weight on your hands during gaming, CoolyFone is powered via the included USB-C cable. Simply connect it to any standard USB phone charger, power bank, or laptop port.

No. CoolyFone is engineered with a custom low-noise hydraulic bearing fan running under 25dB—quieter than a whisper. Your team voice chat, Discord, and streaming microphones will not pick up background noise.

Not at all. The detachable clip is lined with soft silicone padding to safeguard your phone frame against scratches, and its slim arm profile avoids interfering with side volume and power buttons.

We offer a 30-day money-back guarantee. If CoolyFone doesn't keep your phone cool and your gaming smooth, simply contact our support team for a full refund. We want your purchase to be completely risk-free.

All orders are dispatched quickly with free standard shipping. Orders arrive within 4-8 business days with real-time end-to-end tracking provided straight to your email.
