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

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!

Definitely 4-5 star. I don’t know how it does this but it literally gets cold like an AC. The only downside is side is that it has to be plugged. It fits well, strong magnet. Looks really cool and you can sync with the lights on it. Not complaining about the cost. Can’t speak on reliability yet because I recently bought it but it’s definitely working.

I love this cooling device. Works very well, I am a roofing project manager, so I do roof inspections and small repairs. My phone will get super hot but with this I am able to keep using my phone. The magnet aspect is great! I have a Galaxy Z fold 7 and it sticks to my phone really well! It gets super cold quickly. Only downside is that it had to be connected to a power source. That's the reason I took a star! I have to carry my battery pack with me in order to use this.

I really like this phone cooler/fan. BIG Pokemon Go player. It works almost questionably well. Within second it's icey cold to the touch. Like actually cold cold. The magnets work great, plus the side grips work well if needed. You have to press them harddd to get on. 1 Con: if you want to turn off the RGB light, like myself, you have to download the app and it's not on the app store. It's an apk file, but if you're buying this for your phone, hopefully you know how to do all that. But app could be considered hard to get working. Otherwise I love this thing. I would buy more from the company

Came with a damaged backplate (where cooler meets phone) and missing protective films. Annoying - especially since the cooler works pretty well. Whoever is selling these is just not doing a serious job. It also came loose in a package with the delivery parts exposed.

I hesitated to spend this much money just to cool down my iPhone while I play Pokemon Go - it seemed like a silly extravagance until I prepared for my first in-person event, Go Fest Chicago 2026. So I went ahead and got this, and I’ll never play in the sun without it again! No more squinting at a black screen and wondering if there’s anything there to catch or not. No more phone so hot I can barely hold it. This thing not only keeps my phone super cool, it looks super cool, and maybe that makes me super cool too! I saw that Fleece King has this one too, so it must be awesome. Seriously, I love it and wish I hadn’t waited to buy this. Just go ahead and get another power bank so you can keep your phone charged and run this cooler. And btw, I could barely hear it running at the highest speed when playing outside.

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.

While this little cooler is incredible, it ships with max fan and some really irritating lights. DO NOT USE THEIR NON-PLAY STORE ON-LINE ONLY APP to make any changes! They will require you to give them (China) full access to your contacts and phone records to download using their on-line app only! I recommend you use a burner phone with NO personal information and connect via a public wifi. Be prepared to get the program in Chinese but this is the only way I discovered to avoid a massive data breech. Use AI to guide you, if needed. Once you get into the app, recommend you set the fan speed to "Smart" and turn off the irritating lights. It works great once you avoid their dangerous direct app using your fully populated personal phone by being essentially anonymous.

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 €.
