Black Shark Phone Cooler for Gaming FunCooler 4, Wired Mobile Phone Cooling Fan Lightweight Quiet with RGB Light, Cellphone Radiator for 2.67-3.45 inches iPhone/Android, Retaining Bolt

Love this!Bought it to put on my phone while live streaming Fastpitch softball games. First one I received, one of the clamps broke, I sent it back and the other arrived the next day. I highly recommend downloading the app and enabling AI mode as it uses a lot less battery and maintains the temperature. The app also allows you to turn off the lights (the lights are a waste of power during the day).

I use this as a phone mount for my car. I drive something with a convertible rooftop, and it's frequently down in the summer, which means my phone is not only under the windshield and not getting airflow but is also getting blasted by blazing sunlight. I have been using this for a while, and it works excellently. The gripping arms are more sturdy than other options I have tried, and this does an excellent job moving heat so long as the fan isn't blocked. Even then, it still does well enough. The fan is a bit loud, but when driving I don't hear it and protects my phone from overheating while running my Android Auto. Absolutely recommend and I plan on getting another. Just note, this won't work well with 99% of cases! It works best if you don't have one at all, but I was able to find one for my phone made of a thermally conductive material.Quick additional note: Make sure you use a strong enough USB power adapter! Even some of my 15w USB-C bricks don't like this thing and it won't power it. The technology these things use is VERY power hungry and not just any USB adapter will work, if it doesn't power on- try something else!

This product is exceptional. Spring clips fit right on place, and make the device easily adjustable to most places your phone needs it. The cooler does need a relatively flat area to clip on to, which takes away space around camera notches. The back of the cooler has a rubberized pad, which helps it grip to the back of your phone, as well.The cooler functions very quickly, getting cold enough to build condensation in as little as ten seconds, at times. The amount of condensation hasn't become a worry for me. Further, and app is available which allows control of the fan speed (on a manual or automatic setting,) as well as allowing you to adjust settings for lights on the back of the device.It doesn't have a battery, and will need to be plugged in to work, but it does come with a power cord that's longer than my phone cord, so I haven't had much issue with cord length.All-in-all, great product. Does well to cool the phone, and doesn't draw much power doing it.

Ok I don’t normally review stuff but this one is a bit of an exception. My stupid iphone 15 kept overheating while using GPS on the dashboard of my car so I needed to have something to fix that. This product immediately solved that problem. I 3D printed a bracket to hold the cooler on the phone mount and it hasn’t overheated now. The front of the phone is even COLD TO THE TOUCH now, despite me having a thick case on it and it being in direct sunlight!!!

This thing is trash. Bought it to help cool off my phone from time to time. Got it and, unless it doesn't come with one, was missing the cord to use it. The first time I plugged it in, it turned on for a second and died. Got a replacement and it worked for 2 uses and died too. Don't waste your money.

Works great, perfect solution for game changer phone overheating situation.

It's colder than you'd think. Using it to cool down my Capture Card for Live Streaming. LOL

I’ve had this for 8 months, it works very good at first, it keeps the phone cool as it’s supposed to. But it stops working…. I’ve had to replace cords just for it to work again, the cords still charge other devices, but for some reason it just doesn’t work with the cooling fan anymore. Which is pretty annoying since the cords work fine except when it comes to the cooling fan, perhaps the cord gets too hot. I’m not sure what the problem is.
