Black Shark FunCooler 5 Magnetic Phone Cooler - Fast 20W Cooling

In this review of the Black Shark FunCooler 5, the bottom line is simple: it's for mobile gamers and heavy-phone users who need aggressive, plug-in temperature control. The FunCooler 5 uses a 20W Peltier element to pull heat away from the phone rapidly and its strong magnetic hold and RGB lighting make it a natural fit for handheld gaming sessions. It is not a battery-powered solution and requires a Type-C power source over 20W, so buyers who need cordless convenience should look elsewhere.

Key Features

• 20W Peltier cooling: The built-in TEC element drops device temperature quickly, which helps maintain performance during extended gaming or streaming sessions.
• Simple Type-C control: A built-in Type-C port makes it plug-and-play with supported power adapters so the cooler is ready to run as soon as it is connected.
• Two operating modes: Overclocking and silent modes are selectable with one button, giving users a choice between maximum cooling and very quiet operation.
• Strong magnetic hold: The 12N magnetic force and removable grips keep phones attached securely while allowing use on non-magnetic devices.
• Compact, lightweight design: At about 0.18 lb the cooler is easy to hold for long sessions without adding significant weight to the device.
• RGB lighting effects: Four configurable RGB levels add atmosphere to gaming setups and can be toggled with a double-click.

Who It's For

The FunCooler 5 is aimed at mobile gamers, streamers and anyone who pushes a phone hard enough to see throttling or overheating. Its fast 20W Peltier cooling and strong magnetic attachment suit modern phones and even small tablets when used with the removable grips.

It is not ideal for users who need battery-powered or fully wireless cooling since the unit requires an external Type-C power source above 20W and the data/power cable is not included. Buyers who prioritize long-term durability should also be aware of mixed reports about build longevity.

Pros & Cons

Pros

• Very effective temperature reduction thanks to the 20W Peltier element, which helps sustained performance.
• Quiet operation in silent mode at roughly 30db, suitable for focused play or video viewing.
• Lightweight, ergonomic vertical air duct design keeps heat away from the hand and does not obstruct gameplay.
• RGB lighting and simple one-button controls enhance the gaming experience without complexity.

Cons

• Requires an external power source over 20W and does not include a charging cable, which limits out-of-the-box use.
• Some users report inconsistent build longevity and occasional early failures, so durability may vary.

Our Verdict

The Black Shark FunCooler 5 is a practical, high-performance wired phone cooler for mobile gamers and heavy users who need fast temperature control and a secure magnetic mount. It offers very effective cooling, quiet operation and a compact feel, but requires a proper >20W Type-C power source and has mixed feedback on long-term durability, making it best for users who value immediate thermal performance over cordless convenience.

Frequently Asked Questions

Does the FunCooler 5 work without a power adapter?
The unit requires a Type-C power connection and will not operate without an external power source; power must exceed 20W for best performance.

Will it attach to any phone?
It uses 12N magnetic force plus removable grips so it works with magnetic iPhone models and many Android phones when the grips or copper nut adapter are used.

Is it noisy during use?
In silent mode the operating noise is around 30db, which is quiet enough for gaming or watching videos; overclocking mode is louder but provides stronger cooling.
