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.

So rarely does a cheap Amazon gaming product meet but totally surpass your expectations. I have only had it a week, but this cooler has totally changed my gaming experience on my S22 Ultra. No longer does it get hot enough to nearly burn my hands while playing COD: Mobile or start thermal throttling. The phone stays barely warm with this attached and running and I see no performance drop at all. It also feels high quality and I don't have doubts about its longevity like most Chinese products I purchase. I will be buying more of these for my friends and family. That's how good it is.

Works as it should gets Ice cold to the touch but the real issue is it does not spread cooling it just cools one spot that’s which does not improve cooling as I am still getting frame drops during gaming and hot cpu thermal throttling and ur gonna need a high watt portable charger to get full cooling performance which is about 50 watts which is INSANE but does cool at lower watts what I was using was 35 watts all I had it’s fine but definitely returning it it does not meet my expectations also ur gonna have to take off case and so much limitations to this product but at the end of the day it’s a premium product for sure but not worth 24 bucks since its a phone holder version If I would you I would just game on your phone in a very cool room

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.

Like many other reviewers have mentioned, after just a few months of light use (I have another brand's phone cooler too) I bought this as an extra way to keep my phone cool while driving with a hot sun beaming into my car. While it fit my iPhone 16 Pro and Galaxy S25U just fine, I used it maybe 3 or 4 times per week totaling about 25 uses MAX. I then plugged it in to use one day while my phone was updating and the faintest red light appeared and blinked and the device would not turn on, no matter the power source or cable used. The actual fan feels oddly hefty, but still poor quality. Since it failed so quickly, I can't recommend this to anyone who is in a position of needing one of these for their phone. I do not use my phones for gaming at all. Zero stars. I have a cooling fan from TRILINK which I bought 3 years ago and still works great. I have

The temperature dropped from 42 C degrees to 36 C(samsung s22 plus)

This is exactly what I wanted and needed. It works very well to cool my phone. The only thing that threw me was it didn't come with the cord needed. I have other USB c cords though so it's fine. I would recommend it.

I use this as a phone mount for my car. I drive something with a convertible rooftop, and it's frequently down in the summer, which means my phone is not only under the windshield and not getting airflow but is also getting blasted by blazing sunlight. I have been using this for a while, and it works excellently. The gripping arms are more sturdy than other options I have tried, and this does an excellent job moving heat so long as the fan isn't blocked. Even then, it still does well enough. The fan is a bit loud, but when driving I don't hear it and protects my phone from overheating while running my Android Auto. Absolutely recommend and I plan on getting another. Just note, this won't work well with 99% of cases! It works best if you don't have one at all, but I was able to find one for my phone made of a thermally conductive material. Quick additional note: Make sure you use a strong enough USB power adapter! Even some of my 15w USB-C bricks don't like this thing and it won't power it. The technology these things use is VERY power hungry and not just any USB adapter will work, if it doesn't power on- try something else!

前にこれより高額の最新モデルのスマホクーラーを買いましたが高出力充電器だと動かないわ買って半年で動かなくなるわでどうせすぐ壊れるならとこっちを買いましたがぜーんぜんこっちでええやんけ。 半年以上経ってもバリバリ冷やしてくれるし充電器の相性も無いし。 今使ってるの壊れたらまた買います。

İnanılmaz bir soğutma performansı var çok memnunum. 14 Pro Max için satın aldım Razer Magsafe Cooler dan geçtim ikisi kıyaslanamaz bile. Isınma sorununuzu kesinlikle çözer bu ürün.

This cooler delivers on its promises. I purchased it for gaming and overheating issues that caused lagging in the game. Surprisingly, it resolved all these issues effectively.

Better than the last one he owned.

Yes, this is an ice pack for your device. Whether it be an iPhone, external hard drive, anything that gets hot. It has a fan, the speed of which you can control and the higher the fan, the colder this gets. I mean really cold. Just like an ice pack you take camping and put in your cooler. So with that, comes condensation. I had it on my iPhone for a few minutes and shot Pro Res 4K 60. The phone usually gets warm and eventually hot. But not with this thing on it. However, when I removed it from the phone, it was wet. I wiped it down with a paper towel and it only took one pass to make it dry. So I really don’t know how safe this is developing that much moisture on your electronics. Likely in the right application it’s fine. But I caution anyone buying this to be very careful on using it. It does work though absolutely. My phone was cool to the tough after ten min of video recording in high res 4K 60. Not room temperature, but cold. And yes this cooler has fun RGB lights on it while it works. My biggest issue I think is it needs to be plugged in to function. I pitched a different model of this machine that comes with its own battery so you can go totally mobile using it. This is an amusing experiment for me. That’s where I’m at with it. I bought the Tilta Khronos Ultimate for my iPhone 15 pro max and it too came with a fan. But it’s just a fan. It got me thinking about my other iPhone rigs and here we are. I recommend this as an experiment. Can’t say for sure it will be a staple in my set up yet. Trial and error needed. But it is a fascinating device.
