Black Shark Magnetic Cell Phone Cooler, RGB Phone Cooling Fan Portable Lightweight Mobile Phone Cooling Fan, Phone Radiator with Larger Cooling Area for Phone/Tablet/IPad (White)

Cold as block of ice or at least very close to it. Magnetically attaches through my iphone case. My case has a ring stand that may help but all I know is it works well and I see no need to remove my phone from the case. It's quiet and the led lights are a fun little addition. I loaded the app that came with it which allows you to try different light and color motion options. There's a few good ones I really liked and all of them are customizable for color and speed. Even though it has nothing to do with cooling my phone, I still liked it. Feels well made.My only gripe was that it took me about 5 tries to get the optional spring loaded grippers to attach since the instructions didn't say much. Keep trying, press down in the direction the phone would be located and it eventually snapped. Since the magnet works well for my case, I won't be using these. Once installed, I could see they did fairly well. They do give me the option to cool from the screen side which might be a bit more effective if you didn't need to see the screen. However, it really seemed to be doing a good job from the back through the case. I don't think I'll need this option

I picked this up because I was going to be playing Pokémon go fest in the hot central Florida heat. This thing cools down quick and it really helped keep my phone from overheating and lagging. The magnetic connection also made it really easy to pop on and off so I could share it with nearby friends if their phone started overheat. This worked very well from my iPhone in particular because I just use a bumper case which has the back exposed. So I can’t speak to how it works through a thick case. One extra perk of this wants to put the cool surface onto my neck for a quick little pick me up in the hot heat. Highly recommend!

This is a great product! It’s been been very helpful in keeping my phone cool while playing Pokemon (a battery drainer!). It could only be more perfect if it was wireless.

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!

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

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.

Excellent working the only issue is that it’s not rechargeable, it need to be plugged in for it to work but decreases the temp pretty fast I love it

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
