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

Too often phone/laptop coolers will simply turn on the fans and force air into the unit, which is extremely inefficient. As with the CPU, cooling is done by removing heat from the device, which is part of what happens. The fans on the outside are like a range hood, blowing out the current heat. In addition, the surface of this device that comes in contact with your phone becomes incredibly cold, which cools the device extremely effectively. Of course, it's frustrating that the phone itself doesn't power the cooler, but I think that's because the cooler uses power. much power. If it were just fans I think it could be powered by the phone but due to the semiconductor aspect it draws a lot more power. Consider a window air conditioner. It uses ONE ton more power when the active cooling aspect (compressor coils) is on. If you simply leave your window air conditioner in "fan" mode, it will use significantly less power but will not actually cool anything. When using it on the go, I use an Anker power bank to power both the phone and the cooler. When I'm home, I connect both. All this indicates that it is extremely effective.
