Review on 🌬️ Ultimate Cooling Solution: IVY Semiconductor Refrigeration Phone Cooling Fan - Black - Ideal for Android & iOS Gamers by Dave Giri

No power button and you need to connect another USB-C cable to make it work. But in general it really cools down the phone. You'll feel it on the metal plate as soon as you turn it on. I would recommend this product if you have phone heating issues. Mobile players should get this. I used a Rog 2 phone before switching to Samsung and I can say that the fan really makes a big difference in the phone's performance. You will not regret buying this product.
