Meets and surpasses expectations.
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.

Surprisingly effective
I wasn't expecting too much from this tiny fan, but it works shockingly well. I wasn't expecting it to get so cold. I got it so I could play a mobile game that turns my phone into a furnace. Taking the case off my phone and attaching this cooler to it directly worked wonders and eased a lot of my anxiety about toasting my phone's internals. I hooked it up to my phone's charger as a power source after reading reviews about it being picky about power cords and it worked great.

Listing needs improvement
The design is poor, the explanation of the design on the listing made it difficult to understand if it could be used for a larger tablet (it can't). The clips cannot be removed. This was not helpful for what I needed.

Enfría bastante
Funciona muy bien. Realmente enfría bastante. Luce de buena calidad. Utiliza cable, no batería, por cuanto supongo debe tener un tiempo de vida mayor. lo recomiendo.

Es una solución real a un problema real.
Si eres un jugador casual, es un gasto innecesario. Pero si juegas competitivamente o haces streaming desde el móvil y notas que tu teléfono "arde" y pierde fluidez, el Black Shark es probablemente el mejor del mercado en relación calidad-precio. Es una solución real a un problema real.

Best Cooling Fan for Mobile Gaming
I've been using the Black Shark Smartphone Cooling Fan for about 2 months, and it has exceeded my expectations. The cooling performance is excellent and helps keep my phone at a much lower temperature during long gaming sessions. Before using it, my device would get quite warm after extended gameplay, but now it stays noticeably cooler and performs more consistently. The fan is easy to attach, feels sturdy, and starts cooling almost immediately. It's especially useful when playing graphics-intensive games or charging while gaming. The build quality feels premium, and the compact design makes it easy to carry around. Pros: Powerful and effective cooling Helps prevent overheating Improves gaming comfort during long sessions Easy to install and remove Good build quality Portable and lightweight Cons: Fan noise can be heard at higher settings Adds a little extra bulk to the phone Overall, after 2 months of use, I'm very happy with this purchase. It keeps my phone cool, helps maintain smooth performance, and is a great accessory for anyone who spends a lot of time gaming on their smartphone. Highly recommended! 🎮❄️

Black Shark fun Cooler review
This product really works, in other coolers the air leaks from the holes on the sides, but not in this, the cooler is quite powerful.

Vor- und Nachteile!
Montage und Befestigung am Handy ist gut gelöst und stabil. Leider ist die Kühlleistung (10W) besonders im Sommer über einem heißen Armaturenbrett zu schwach. Der Black Shark FunCooler 5 mit 20W hat da deutlich mehr Bumms, allerdings ist dessen Befestigung am Handy zu fummelig!
