Black Shark Funcooler 3 Pro

The Black Shark FunCooler 3 Pro is a high-performance smartphone cooling fan designed specifically for gaming phones and heavy performance use, where devices tend to overheat during long sessions.

It uses a thermoelectric cooling (TEC) system combined with a high-speed fan, which actively pulls heat away from the phone instead of just blowing air. This helps reduce device temperature significantly during gaming or intensive apps.

In terms of performance, it can lower smartphone temperature by up to around 20–30°C depending on conditions, helping reduce thermal throttling, FPS drops, and lag during gameplay.

The cooler connects via USB-C power (recommended 20W or higher) and is controlled through a physical switch, with some versions supporting Bluetooth for extra settings and lighting control.

It uses an adjustable clamp design that fits most smartphones, typically supporting devices between 67mm and 88mm width, making it compatible with most modern phones including gaming devices.

The design also includes:

• RGB lighting effects for gaming aesthetics
• Vertical airflow design to keep heat away from your hand
• High-efficiency heat sink system for better heat dissipation

It is mainly built for users who:

• Play heavy games (PUBG, COD, Genshin, etc.)
• Record or stream for long periods
• Want stable FPS without overheating

One important note: it needs a strong power source (at least ~20W), otherwise cooling performance will drop or it may not run properly.

Overall, the FunCooler 3 Pro is a professional-grade gaming phone cooler focused on keeping performance stable by actively controlling heat during heavy use.
