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

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

The media could not be loaded. Not very loud, sounds like a fan. In the video, it’s at the max setting. However, this thing is brilliant. It’s so effective at cooling the phone down that within a minute of my iPhone giving the temperature warning from being too hot, I put this on and the screen was cold to the touch. In one minute. I can game freely now without the phone getting super hot and limiting performance and charging capability/reducing screen brightness. And also let’s be honest, it looks cool.The back of the device does get quite cold surprisingly and it pulls heat away fast, and I’m using this with the phone in an otter box defender case which is the opposite of a thin case. Even with that, it cools the phone down extremely fast and keeps it there. Very very impressed.

Keeps devices really cool I use this for my Ally ROG and it keeps it from over heating!

Amazing fan cooler. The base is incredibly cool to the touch and makes the MagSafe area cold. The dispensed hot air does get caught around the surface of my phone but I believe it can keep the internal temps cooler than without it. I tested a recording with the fan on and do notice the fan noise is captured in the native iPhone video recording. It sounds like a distant vacuum sound since the microphone is sensitive to all sounds. I think it would be better to have an external microphone that can deaden or distance the fan noise. Overall this fan would be great for gaming. Update: decided to return this as the noise is too loud for my use case for video recording. I found a different brand that has a switch control for speed and on/off so I can control the noise level better. This is still a solid cooler for non video/audio recording use.

Quiet and icy cold. Keeps my iPhone 15 pro super cool. The 15 pro runs very hot when charging and when streaming and gaming. This tiny fan needs a USB-C power source but definitely keeps my phone cold. Highly recommend.

The media could not be loaded. I’ve now bought the Black Shark Magnetic Cooler twice for my iPhone 15 Pro Max, hoping the first issue was a one-time problem. Unfortunately, I was wrong. Both coolers broke within a few months, and I regret giving Black Shark a second chance.This model is not only too small, taking a while to cool down, but both units also failed the same way. Each time, the cooler stopped working, overheated, and caused the cable to burn. This product is a serious fire hazard—if I hadn’t noticed in time, my house could have caught on fire.Adding to this, Black Shark’s customer support has been slow and difficult to reach, making the experience even more frustrating. I would not recommend this product to anyone, and I won’t be purchasing from Black Shark again.

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

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
