Phone Cooler for Gaming, 27W iPhone Cooling Fan with RGB LED Semiconductor Heatsink Cooling Case Enfriador para Celular, for iPhone/Android Phone Gaming, Live Streaming, AI Smartphone Temperature

I’ve been using this for a while now and it works a great. Very quiet. And it gets really cold instantly. Definitely worth the money

This Stjiatu Phone Cooler is a must-have for serious mobile gamers and live streamers. The 27W semiconductor heatsink is incredibly effective, successfully dropping my phone's temperature during long, intense gaming sessions and eliminating frustrating performance throttling. The RGB lights are a fun touch, giving the setup a cool, aggressive look. While it's a bit bulky and the power cord placement can occasionally be awkward, the ability to maintain peak frame rates makes it a fantastic investment for $21.99. If you struggle with an overheating phone, this cooler provides the necessary performance boost.

I haven't used this cooler to its full extent yet, since I'm waiting for my gaming phone to arrive, then I'll test it for some time and edit my review, but as of now I can already tell this is a pretty good cooler, the only reason I'm not giving it 5 stars is because it does get pretty hot (the part where you put the USB) after some minutes in the highest setting, not a big deal because the cooling is still amazing, gets to -3 degrees in seconds, I was stunned really it's very powerful, very quiet too for how well it cools, I'm using my Galaxy s26 ultra case for reference for now and it fits, given it's not the biggest phone so you might want to get a cooler with a better fit if your phone is considerably bigger. Very easy to set up, just place it on the back of your phone, plug it in, and start. It has 3 modes, low power, high power, and ai mode, which I'm not really sure of how it works but I think it works by switching power modes depending on what the temperature it detects is. It's a slight bit too big for my taste but it's not a big deal, very light as well. Overall I recommend this (pretty cheap btw) cooler if you're into intensive mobile gaming, if your phone is on the bigger end you might wanna get something else.

I’m not a gamer, but my phone gets hot allthe time. So hot to the point where u can’t touch it. I have an iPhone 13, it fits it perfect but be mindful if you have a pop socket, position it properly so it doesn’t get in the way Cooling: Cools powerful I live in florida and it gets heat wave hot all the role, i was outside recently and had it on my phone, then it didn’t make my phone freezingg cold but when i touched it phone, i felt nothing more like romtemperature and that day out was hot. But if your inside, it freezes it cold, so basically i would definitely get it again Why did you pick this product vs others?: Rating, i looked all alot but felt comfy with this

I was skeptical at first if this would actually work, it does! It gets ice cold and simple to use. The only con I’d say is that it has to be plugged in via USB-C; it would be nice if it was wireless; otherwise it works flawlessly. **Updated 5/7/25** Today I went to use it and it no longer works. I plug it in and click the button and it comes on and then shuts down and the screen turns black. Works great but has a very short lifespan before it stops working.

Helped keep the phone running smoothly during Pokemon Go Fest Chicago in the hot sun. Worth every penny.

My iPhone 15 pro max gets very hot after using it for about an hour, I needed a phone cooler and this was pretty interesting so I decided to give it a shot. It has a nice design and looks cool but here are a few points about this item I did not like. 1. Wired, you need to plug into a wall outlet so you now have to plug in your phone and also the fan. The cable itself isn’t very long, wish this product was cordless and had an internal battery so no wires need to be plugged in. 2. iPhone 15 pro max with a phone case most likely won’t work as it fits very awkwardly. I understand that it defeats the purpose if you have a phone case but the phone costing so much I don’t not using one. The fit is very snug and might break after a few uses but I can’t justify removing a phone case possibly scratching my phone.

Super freken cold!

Didn't work out of thr box. It switched on only for 1 sec and never turned back on. Used regular 5V 2A changer.

Wat soll ich dir sagen? Dat dingen macht wattet soll, et Kühlt. Et Kühlt sogar so krass, dasse ab und an mal en tuch brauchst, weil das dingen feucht wird wie deine alte, wennse dich nich sehn muss. Ohne mist, dat dingen hat bei exessiven Gamingsessions aufm Handy ( Ich darf dat sagen, hab sogar Wreckfest darauf gezockt) mehr getropft als ne nonne die dat erste mal berührt wird. mit mitte 40.

جامد فشخ بس مش هتفهم حاجه منه الاول اقرا الورقه اللي مكتوب عليها الكلام الانجليزي والصيني وهتفهم وبس كده

I got this to cool my Samsung Galaxy S21 on hot days, especially outdoors when sitting in a purse cannot keep it cool enough. Note: the phone it's on in the attached videos is a different Samsung A16 phone I use for work, which at 7.5 inches wide is half an inch wider than my personal phone. I tested the device on both phones, though. There are also 2 more photos included, showing the device off and on, but on its own. For the A16 it took a little effort to get the device to stretch a bit so I could get it on, but it works. Meanwhile, it was a piece of cake to get it on my S21, and there's still enough give in it to slide up and down the phone a little bit, which is fine. Alas, if you have an older, smaller phone with a width under 7 inches, this will be too wide to fit it. And if your phone is any wider than 9 inches wide, it won't stretch any farther than that. As for function, all 3 modes seemed to cool each phone down fine. L1 mode is quiet cooling as advertised, but cools the slowest - albeit at still a good speed. This mode is meant for those doing livestreams or vidcasts who don't want any noise - or you'd rather cool the phone a tad slowly than hear the fan running. The L2 mode for maximum cooling is constantly loud, with the fans in it running at top speed - although it's never louder than, say, a hot desktop computer running its internal fan. This is for when you need the phone cooled down fast and it's hooked up to an outlet or a battery with lots of charge. AI mode is supposed to "intelligently" alter fan speeds to keep the phone at 15C, but in practice it seems to work at top speed or medium speed to lower the phone temperature to 10-15C and then turn off the fan until the phone heats up again. This is for when you want to keep the phone cool, but not cold, or you don't want to waste power. I'll have to post an update in a while to report how it goes in the long term. But for now, it seems to be the right product to cool my phone down on very hot days.
