Black SharkMagnetic 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’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

If you do a lot of work on your phone and it gets hot, these are fantastic 😎

I bought the Black Shark 4Pro for my IPhone 13. I was having overheating issues while mobile gaming. However, that is not an issues anymore with this product attached to my phone.

The media could not be loaded. i’ve had this for about a year and use it daily. it cools the phone well but there is no way to clean it as it does not come apart. $50 for one year of useupdate: seller reached out for a refund which i appreciate!

Works very well! Not a very portable item since it has to be plugged in.

The app website is down, you can't download it and it appears to be gone from the Internet. I found a copy but it force closes when I try to open it. This is more crap from a crap company.

Pros: it does stay very cold and the noise that it makes is ignorable if you have ever gamed on laptops and have used cooling fans for those. I would say it’s close to internal fans from REDMAGIC or other gaming phones.Cons: it cools you battery the most thus when gaming, the cpu heats up , which is closer to your camera and this heat to move to the center takes a while and does not directly cool your cpu. This means you either have a cold center phone throttling or you can buy a heat sink for your fan and this probably won’t fit your phone size if it’s a smaller form factor

Works great! It’s Ice Cold on my iPhone.The fan is very quiet.
