Cell Phone Cooler Black Shark Fun Cooler 3Pro, Cellphone Radiator with Sleep Timer/Fan Speed Settings for 2.63-3.46 inches iOS/Android Semiconductor Heatsink Cooling (Purple)

this thing is unbelievable. Does it have a refrigerant in it? lol I forgot to turn it off and left it in my room... come back like 15mins later... it has frosted over! what?

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!

Minus one star for exaggerating the wattage. I bought both the 3 pro and the 4 pro. On max, the continuous power is very stable at 15W for the 3 pro and 20W for the 4 pro. They claim 20W and 27W, respectively. The 4 pro is noticeably faster in cooling and is just as robustly built, but is a step larger in all dimensions (as expected I guess).

Works great

Funciona muy bien lo recomiendo 👌🏻

Okay first off yes it will cool your phone and display the temp in C can't change to F which isn't a big deal. What is a big deal is there is no way to take this hunk of molded plastic apart. Why is this a problem? Well this becomes a problem because like every fan ever fibers, dust, and other inconvenient particals can become trapped, wrap around the fan base and other wonderful things that go along with that and good luck reaching that. And to top it off now less then 2 months of use the C port doesn't work unless inserted a certain way and pressed firmly. And I know you're thinking "hey that happened with my phone and I just dug out the gunk and stuff and it made a connection perfectly again". Well I thought of that, cleaned it back to new, verified nothing is in there and tried many many many different cords. It's the contacts inside the device 100% I've come to discover. So yeah, don't waste your money on this POS unless you are looking to get another one in a short space of time and would like a paper weight.

Great product, my son loves it...keeps the phone cool and looks great with the lights on it

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.
