Black Shark FunCooler 5 Magnetic Cell Phone Cooler for Gaming, Portable Mobile Phone Cooling Fan with RGB Light, Cellphone Radiator for iPhone Magnetic Series/Android/Tablet/iPad (Black)

I will admit I was skeptical, but this actually works and gets about 10% more performance from your device from mitigating some thermal throttling. You must remove the case for this to work because it has to make direct contact with the back of the phone. I used the Wildlife Extreme Stress Test (puts you phone under heavy graphics load for 20 minutes) and there was a huge difference. Round 1 was 3743, and with cooling it only fell 12% to 3291 (88% stability) on its worst run. Without the cooler, it fell 21% from thermal throttling all the way down to 78% stability. The Solar Bay ray-tracing Stress test was even better. First run was 5431, with the cooler it only dropped 1% on its lowest run which means basically no throttling at all. Without the cooler it fell 11% from thermal throttling. Overal I'm impressed and its a good value for the cost to push a bit more performance from your device if its generating a lot of heat. It can save some battery wear and tear by keeping its temp down.

The few people rating this one star because they dont know how magnetism works need to grow a brain. Its not going to stick to your phone if your phone isnt magnetic in that particular spot . Cools my 'S25 Ultra' very well while playing intense games like 'Zenless Zone Zero' or 'Neverness to Everness' at max settings. Smooth gameplay with a cool looking device for hours at a time. The magnet could be a little stronger but I use the clips anyway, which fot great. Awesome product

Gets the job done fast and is super quiet only been using it for a day to play call of duty mobile DMZ mode

I do a lot of Pokemon Go an I was very impressed with how cool my phone got after use. I was expecting fans throwing cool air on my phone but it actually a little freezer that cools it down. One thing to note is that phone would not power on the cooler. I had to use a power bank which is fine with me. You dont need to keep it long on your phone bc it cool it down really fast and keeps it cool for a good while.

I’ve tried a few different active coolers and this works very well.

Used it maybe 7 or 8 times no more than 10 minutes but sess than 54 days later it's dead… started to fail around 30 days just didn't believe it. But its just a beverage coaster at this point.

Ha sido una buena compra en lo personal me gusta y me ha servido bastante y lo recomiendo mucho!

以前使っていた他社の安物ファンは背面が金属だったが、本製品はシリコンパッドのような感じでiPhoneに取り付けた後にずれないのが良い 今のところは初期モードでもかなり冷えるのでそれで充分に感じる 強モードは少しうるさい 初期モードは約16W前後、強モードは27W前後のようなので電源はPD対応で30W以上のものが必要だと思われる 操作方法 電源ON/OFF： 電源ON中にボタン長押しでOFF、電源OFF中に短押しでON モード切替： 電源ON中にボタンを一回押すと、標準と強モードが切り替わる LED設定： ボタンを2回素早く押すとLEDカラーが変更できる 注意点 本製品をケーブルに繋いだままボタン長押しで電源をOFFにして、後からACアダプタの別ポートで他の機器（モバイルバッテリーなど）を充電し始めると、ファンの電源も勝手にONになってしまう挙動が見られた 新しい接続が関知されると全てのポートを再接続するようなACアダプタにであれば同様だと思う

Value for money good cooler
