Phone Cooler for Gaming Streaming Radiator with LED Display Semiconductor Cooling Ideal for Android iPad iPhone Compatible with MagSafe

I have to take teams meetings on my iphone, which makes my phone heat up like crazy. Used this on the magsafe ring, and if actually managed to keep my phone from over heating in my hour long meetings. This does have to be plugged in at all times in case there was any confusion.

Using this on my Z Fold 5 while gaming on Warzone Mobile, made the phones temperature go from 45C° to 28C° within a few minutes. Highly recommended, but I hope I can get a reply with this question, can you tell me what are the two modes on the button? Can you tell me what the second button press does?

I assume it's using the peltier effect since the device got a fan , the cold side become cold when you plug it in and while it's not as cold then what I expected it to be this can work on a phone charger for as long as it's provide enough watts.if you're considering using this on a steamdeck you will have to expect this to not make a large difference since the steamdeck will just have it's fan spin slower if the cpu temperature is lower then expected when a game is running , maybe you'l get 2 to 5 degree less at best.but the device itself produce enough cold for a much less energy hungry device like a cellphone.

I got this for Pokemon Go Fest and it was a game saver. It was so hot outside that my phone started overheating within an hour.It’s a little cumbersome to play and you need to take your case off. But it was worth it because without it I wouldn’t have been able to play.Having to keep it plugged into my portable battery wasn’t great but what do you expect for $20.

My biggest worry with this device was whether it was going to be a niche item I used or an actual good cooling system for my phone when it gets hot. After some testing with it the cooler works great especially for those who game on there phone or do anything demanding.Those who play games like Pokémon Go or anything that requires your phone to run hot on top of being outside I would say this is a must have item. It improves how the apps runs which alone is enough reason for me to buy one, but it will also prolong your battery life.Price wise this is the best bang for your buck you’ll find on the site. Other ones run 50$ or higher for the same or worse results. It also has a nice appearance with a button to change the LED lights on or off.My only downside with the cooler is it has to be plugged in at all times to run, and that taking off your case makes the item go from about a 6/10 to a 9-9.5/10
