Magnetic Phone Cooler 5 Pro for Gaming

The Black Shark BR52 FunCooler 5 Pro is a magnetic phone cooler built for mobile gamers and streamers who need sustained performance during long sessions. It uses a high-performance Peltier element to lower the device temperature by about 95. The cooler attaches with 12N magnetic force and requires a wired power connection exceeding 20W for optimal operation.

Who This Suits and Who It Does Not

This cooler suits iPhone MagSafe users, Android phones with magnetic cases, and tablets that can draw power from an external 20W-plus USB-C source. It is not for buyers who want a cooler with an internal battery for untethered use. It is also not for phones that lack magnetic alignment or cannot accept a clip-on accessory.

The Specification That Decides Fit

The single deciding specification is the mandatory 20W-plus external power delivery via USB-C. Without a charger or power bank that can sustain that output the Peltier element cannot reach its rated cooling capacity. If your typical power source is below that threshold this cooler will not perform as intended.

Questions about this item

Should I pick the 18 RGB version or a different LED count?

This model ships with 18 addressable RGB LEDs; no other LED-count variants are listed for the BR52.

What does the 20 W rating mean when I plug it into my phone?

The cooler draws up to 20 W from a USB-C power source to drive its TEC module, dropping the device surface by roughly 95 °F in overclocking mode.

Does the USB-C port limit cooling speed or noise?

The built-in Type-C input requires a charger that can supply over 20 W; silent mode runs at 30 dB while overclocking mode uses the full power budget for maximum cooling.
