The fan cools the phone greatly and barely uses power, only around 6-8 watts, which is great for use with a power bank. I recommend it because it's cheap, and if you feel the fan on the back, it gets very cold. This is really good.

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

The Gosemai MagSafe Phone Cooler works impressively well in terms of cooling power. It uses a thermocouple plate that gets cold within seconds, efficiently pulling heat from the back of my phone and venting it through a fan system. This design keeps my device from overheating during gaming and streaming.After several months, though, I’ve noticed a few changes. First, the fan’s power is noticeably reduced compared to when the cooler was new, which slightly affects its cooling efficiency. Separately, the magnetic attachment has also weakened over time, so it doesn’t “snap” onto my phone quite as securely. Since the cooler is about 3 inches across and designed with a multi-vent housing, it can only be gripped around the housing itself, so the weakening magnet is something to consider.The LED lights add a nice touch but could use an option to turn off or control the color independently. Overall, it’s a useful accessory, but with a few durability improvements, it could be excellent.

I thought it work well, but it turn out such as waste money. It is not even sticking on phone after I tried several time. The magnet is not strong enough to stick to my phone

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.

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?
