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)

It's good, like really, really good. I am amazed honestly. It gets painfully painfully cold if you touch it to your skin. On my phone, where it's supposed to be, the magnet is strong and the effect super efficient. Phone runs faster and no more overheating. Just make sure the USB port you attach it to is strong enough. If it is not it will not spin full speed or light the light up.

My IPhone gets hot easily, especially when I’m outside and in the sun. A fellow Pokémon GO player suggested I purchase this device. Absolutely works as stated and cools the phone fast.

This phone cooler is compact and nice-looking, fits snugly on the back of my phone. Since I started using it, my phone never overheats anymore while gaming, so there’s no lag at all. It works really well too when I go live streaming, no more stuttering or frame drops caused by high temperature. The heat dissipation effect is really impressive. The only downside is that the built-in fan runs a bit loud. It would be absolutely perfect if the noise could be lower. Overall I’m satisfied with this purchase

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

This thing is damn cold

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.

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 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.

2連ファン（安い）、格安品、バッテリー内蔵2種とこの製品を比較。 冷却モードは2つしかない。電源接続時に動作を始めるせいか、ケーブル接続しっぱなしだと勝手に動き出すことがあります。 冷却面も大きく、今後追記するかもですが、冷却面がゴムパッドになっているのでケース入りのスマホやスマホに直接取り付ける場合も安心安定して冷却できそうだと思いました。先にあげた機種の比較でも冷えないことがなく安定してスマホの温度を下げてくれました。 一つ要求があるとすれば平置きできない点（爪をつければ可能）、遊び終わって充電するときなどにもバッテリーをいたわるためにつけておきたい時などに向きを気にする必要が出てくるところですか

Good quality

Living in southern EU my I phone is always over heating and the screen becomes unreadable. I thought ok … another gimmick to try so the Black Shark arrived and I lm actually amazed it works. Out all day in 28c and it never went dim. When I removed the fan, the rear was actually cold.. Very pleased ..
