Black Shark Magnetic Cell Phone Cooler 4Pro, Portable RGB Cooling Fan, Cellphone Radiator with Removable Grip, App-Controlled Smart Temperature Control for iPhone MagSafe Series/Android/Tablet/iPad

Cools the phone well, perfect to use while gaming. The cooler has different speeds and works quick to cool down the phone.

I bought this mainly for playing Pokémon GO during long community days and events, and it has exceeded my expectations. My phone used to get hot after 20–30 minutes, especially with the screen brightness turned up, GPS running, and an external battery pack connected. Since using this cooler, the temperature stays much more manageable and I don't notice the lag or screen dimming that I used to get from overheating. The magnetic attachment is strong and easy to snap on and off, and the cooling kicks in almost immediately. I also like the RGB lighting—it adds a nice gaming look without being distracting. The fan is surprisingly quiet, so it doesn't become annoying during extended use. Build quality feels solid, and it's compact enough to throw in my bag when I'm heading out to play. Whether you're gaming, streaming, or using demanding apps outdoors, this cooler does exactly what it's supposed to do. For Pokémon GO players especially, it's been one of the best accessories I've purchased. Highly recommended!

I bought this phone cooler specifically for gaming outdoors in the summer, and it has exceeded my expectations. Before using it, my phone would get hot very quickly, causing lag, screen dimming, and battery drain. With this cooler attached, my phone stays much cooler even when gaming in direct heat for extended periods. The cooling is noticeable within minutes, and it helps maintain smooth performance without the throttling that usually happens when temperatures rise. It's easy to use, lightweight, and doesn't get in the way while playing. For anyone who enjoys mobile gaming outside, especially during hot weather, this cooler is a game changer. Definitely one of the best accessories I've purchased for my phone.

Excellent cooler, keeps my Samsung Galaxy S25 Ultra from burning up during gaming at max graphics settings running things like World of Tanks, Call of Duty, Fortnite and Runescape/OSRS. DO NOT GET FOR WIRELESS CONTROL. Get for basic functionality and use the button on it for speed and light control. You're not gonna see the lights on it while using it anyway since it's behind your phone. WHY: App not supported on Google Play/App Store. Chinese Spyware app that wants you to download it from an untrusted source via QR Code included with the cooler. Once installed it requires Bluetooth and Location to be constantly active to...... control my fan speed and RGB settings...? Riiiiiiiiiiiiight. Okay China.

Device is ok right out of the pakage . It'll cool your phone down a bit with the factory settings, but in no way it'll be ice cold. You have to download an app in their site which is hard to navigate because it's in chinese language, even if you translate it it doesn't show you where exactly to DL it. If I have known i wouldn't have bought it.

This item gets and keeps my iPhone cool and running smoothly! I use car play with Sirius and Waze running. My iPhone never overheats or even gets warm! Highly recommend if your android or iPhone runs hot.

If i could leave 0 stars i would… i ordered this product to keep my phone from overheating while outdoors. It arrived with everything brand new. I followed the instructions provided and charged my device. I then attached the clips and mounted it onto the back of my phone and powered on. It made a noise like the fan was running you could physically see it wasn’t spinning or producing any type of air/cooling effect. I requested a replacement and received it fairly quickly.. The only thing was that the box must have been a return from someone else because the box wasn’t wrapped in plastic like the original purchase was. It also only contained the device itself, with no accessories like the clips and charger. Both have been shipped back to Amazon for a refund, although only one device is showing as returned while the other just has details for showing the return label, even though the UPS employee scanned both QR Codes. I hope i have no issues in getting my refund but i can already foresee an issue coming.. Guess we’ll see..

I’ve only had it a day and it’ll work fit on your phone with a bulky case those I’m pretty sure it won’t work nearly ass good with the case off but I bought it for my rog ally because I saw someone say it could be used but of course they fail to mention how they got it to work you basically have to by a magnetic sticker and place it over the vent on the back of the whatever you’re using it on if it doesn’t have mag safe so far I’ve held it on with a hairband and good placement kept my rog in the 60s to high 60s on turbo mode running a decent game at max graphics getting 120 frames and never went past 70 and if it did went right back down I’m scared of the condensation on the back getting into the rog while you’re playing but it hasn’t happened yet but I’ve only had it for a day but it does get cold and fast idk about the fan being loud i literally can’t hear it unless I put my ear to it but I have a lot of background sounds but even when my room was quiet I only heard my game and didn’t even hear the fans from the rog blowing because it was already cooled . Just remember you need a magnetic sticker I found a thermal one that helps with items just like this hopefully it does even better. Only downside is this thing is a powerhouse definitely need a good portable battery if you play on the move and also if you have a multi usb charger make sure it’s a good one my 240 watt charger was overheating running this and all my stuff connected to my ally I have to get a better one now but that cooler came in clutch put right on my usb hub and it was cooled again. Updated: the photo is running borderlands as high as you can on the rog while it’s still playable and I was at high 40’s to 50’s and the heavy parts and 60s almost running around without the cooler my temp was hitting 80 easily and showing no signs of ever going down with this sometimes it’s spiked to 84 for a few seconds but would go to down to 78 like normal I still have yet to find a good spot and good thermal sticker the one I had is too big and completely covered the vent but with the cooler on it’s doesn’t matter also can’t use the sticker with some cases you’d have to put it on the device itself

Works like a charm :) especially when I want to keep playing but need to charge simultaneously. Don’t regret the purchase at all.

i would have given the cooler 4 pro 5 star but the box was damaged and the cooler has some scratches but it works great and there is no compromise in the cooling the cooler is top notch idk how the 5 pro will be if 4 pro is only this much powerfull W product but the cost is little costly u will get this in alibaba express for 3-4k but if someone is out of country better import it but if u want it at the earliest this is the best place to buy the durability is tuff and i hope it lasts if anything i will put another review and the rgb lightnin gis crazy and customizable fits perefectly on the mag safe but saw few reviews where i saw the cooler stopped working after 1 month any ways i willl cover on that as well

Serviva a mia moglie per raffreddare telefono durante streaming. Qualità costruttiva eccellente. Funziona perfettamente. La superficie telefono al tatto sembra uscito da freezer!!!

Ürün türkiyeye sorunsuz geldi. Aras kaargo ile geldiği için sorun yaşadım mardin yerine orduya giden kargom 1 hafta geç teslim edildi ama ürün sorunsuz ve mükemmel kalitede funcooler 4 pro ve funcooler 4 modellerini de kullanıyorum kalite hissiyatı onlardan çok daha önde.

Die angegebenen 27 Watt wurden tatsächlich erreicht, somit stimmt der Wert. Die gummierte Oberfläche ist hervorragend und sorgt für ein kratzfreies Backcover und eine starke Kühlleistung durch die Schließung von Luftzwischenräumen. Die Clips sind auch gut, aber leider quietschen diese etwas, was jedoch echt nicht stört. Die App-Anbindung ist super, auch wenn ich mir ein deutsches Menü wünschen würde (aktuell die Hälfte Deutsch, die Hälfte Englisch). Das mitgelieferte Kabel ist hochwertig, lang und schnell. Ich würde mir einen Kühlmodus mit Intervallkühlung wünschen, gerade um im Standby oder leichter Nutzung das Handy nicht zu unterkühlen. Das Gerät ist alles in allem sehr empfehlenswert und bei Rabatten auch sehr günstig, wie bei mir für ~30 €.
