Neveika Phone Cooler, Cellphone Radiator with Dual Semi-Conductor Cooling Chip, Mobile Phones with a Width of 6 to 8 cm for Tiktok Live Streaming, Outdoor Vlog, Mobile Gaming. (Digital display)

I bought this based on other reviews. I also live in Arizona and the temperature in my car (no AC) is regularly 120-150°F. My phone will shut itself off, close apps, malfunction all sorts of ways in the heat. An ice pack helps but only for a little while.The cooling device is nice. The only thing that may be a drawback for some people is that the cooler needs its own power source. It does not have a battery. The instructions are in English and Chinese, but the installation and use are very straightforward. I run a Galaxy S23+ and this device fits over my phone perfectly and even fits with the case on! It obviously works better without the case as it will contact the phone directly. The air flows IN through the fan on top and blows OUT of the sides. Within moments of installation and proper power source my phone dropped from from 28c to 10c according to the display on the cooler. That's around 85°Freedom to 50°Freedom. A serious difference. My phone is cool to the touch. The fan is almost silent. A tiny hum is all you'd notice. The LEDs are nice and bright.

This product does the job. The cooling surface gets pretty cold and the cooling of the phone is quite effective. My phone was 60°C So I removed the case and slapped the cooler onto the back of the phone. The cooler said 18°C So I thought it was not detecting the temperature of the phone correctly. However, when I removed the cooler to feel the cooling surface, it felt cold! The display temperature must be the temperature of the cooling surface than the temperature of the phone. Anyways, my phone rapidly cooled off to feel just slightly warm to the touch and then I put the case back on and I slapped the cooler onto the glass front instead of the back to cool a bit more. Note that there is no battery in this device so you have to keep it Plugged in someplace for continuous cooling.

Peltier cooling tech is nothing new, but in this application its perfect for thermally limited phones, just be sure to power it with 15W minimum. xD

It can cool down to 0 degrees Celsius

This device does cool but exactly what it is cooling is the issue. My phone heats right under and around the camera. Yet this device is prevented from being placed where it is most needed - by the volume and power buttons. The device clamps to the sides and thus cannot be placed where it is needed most or else it would be pressing on those buttons and taking screenshots continuously.The second flaw is that temperature reading in in celsius. There is no Fahrenheit option rendering that feature useless for most Americans.

Marvel Future Revolution was giving my pixel 4a quite the workout, but this heat-sink-fan-thing did the trick. Dropped temps from 27°C to 15°C in less than 3 minutes. I have to take the case off the phone but since the fan has to be plugged in anyway, I'm not going anywhere while it's in use. Wish I could find another with this type of heat sink, a battery, and grips that wasn't designed for PUBG or call of duty (since they tend to have triggers and little nubs that I don't need), but until then, this is doing the job just fine

I bought this because my phone gets very warm when running wireless Android Auto. Long road trips I worry about the longevity of my phone, bought this and was very impressed with how cool it actually kept my phone.

This product doesn't really cool your phone down, it just maintains whatever temperature your phone is at. After 1 hour or more it doesn't really maintain the room temp as it starts heating and making your phone even hotter.
