Review on Magnetic Cooling Portable Radiator Watching by Larry Cole

This is one of four phone coolers with a semiconductor heatsink that I have purchased. Out of the four, this actually cools my phone down. Even Black Shark's couldn't do that. Now my needs are a bit unique, but if you have the same setup as me you might find it useful. introduced the concept with the iPhone. Since my phone doesn't have built-in magnets, I had to find a suitable adhesive mount. Thing is, I didn't want to put it right on my phone. That meant he had to be connected to the case. After some trial and error, I found the best magnetic "sticker". Then I had to find a suitable housing. It had to be thin enough to allow the semiconductor cooling system to penetrate, but strong enough to offer minimal protection. After finding a suitable case, I set everything up for testing. To start, I downloaded three apps that monitor my phone's temperature. I chose three because they often give different readings. It was as I suspected, but the difference was only a degree. Then I tried all four phone coolers I bought. One was both a cooler and a wireless charger. That was the worst. The temperature has actually risen. Charging your phone always increases your phone's temperature, but I was hoping that a cooler would lessen the effect and then negate it after my phone was fully charged. It's not like this. The second one I tried was very similar to this one. However, it was noisy and didn't cool the phone well in the case. I had high hopes for the third one, Black Shark, as it is made by a famous brand and is expensive. This did absolutely nothing. I mean nothing. The cooled area was very small as it was surrounded by a ring of magnets. Also, it had the same "heat dissipation" sticker as this one, but it wasn't something to put on the device itself. It was firmly attached to the device. And because of the magnetic sticker on the case, it never really made contact with my phone. I think why this particular model works is because the vinyl sticker, designed to dissipate heat, is optional and the surface is clean. Metal. This provides enough surface area to contact both the case and the phone to allow it to cool. During testing, all three temperature monitoring apps showed significant drops while the device was running. Of course, due to the fact that I'm using a case, I can't use the full cooling performance that this device offers. Something I saw when I held it to my bare phone for a bit. The temperature drop was faster and much smaller. However, it gives me enough cooling so my phone doesn't get too hot. After playing some games and using apps that drain battery, my phone never reached the high temperatures it would have without this cooler. work more efficiently, allowing me to reach even lower temperatures when using them. If you have the same setup as me, try this. You can always return it if you find it doesn't suit you. Of course, this is not a perfect device. The fan makes a unique sound during operation. Although it might be me as I have both inner ear problems and tinnitus. It's not particularly loud, just sounds like a whistling undertone. To be honest, the device is not made of the best materials. It looks and feels cheap BUT it works. So the compromise is worth it for me. The RGB lighting isn't the best, but since I can't see it it's not a problem, but I thought I'd mention it. I might buy a second one as a backup as I'm not sure how long it will last. For the price, I think that's an acceptable loss. I will update my review if this device dies within a short time.
