TEC Cooling Fan: Designed for gaming enthusiasts, vloggers, and people who use phone for long time. This radiator is made of Metal and PC. The phone gaming cooler includes two physical switch for easy power control and offers 7-stage refrigeration adjustment. Silent designed fan can efficiently emit wind from all sides, providing a stronger refrigeration effect
Stay Powered Up Anywhere: It includes a 4800mAh detachable external battery which can continuously work for 6 hours. This design makes it effective for outdoor use without being limited by power cords. In order to achieve the best cooling effect, please use 5V 3A charger or above
Rapid Cooling Technology: Using high-performance semiconductor refrigeration technology for effective heat dissipation. Equipped with high speed fan and TEC chip, it takes just 30 seconds to lower your device's temperature to 3℃ in a 25℃ room. This effectively prevents overheating and ensures the stability of your live streaming or gaming experience
Versatile Mounting Options: Comes with magnetic sticker and back clips. You could attach this cooler to most device, such as iPhone /Android phones, iPads, tablets, laptop, cameras, switch, steam deck etc. Non-magnetic phone can be used with magnetic sticker or clip

very good product its actually worthy.
Item is legit. It does what it has been described. It gets freezing cold to the touch. They had to send me a replacement/refund because there was an imbalance connection between the battery and fan. I used it on my iPhone due to battery getting warm/hot due to Apple’s iOS update. This thing cools the back of my iPhone. Highly recommended for temperature control of phone when gaming, ios updates, and outside when charging your phone in hot weather situations.
No packaging box, few accessories
I have to say, this product truly deserves a “wow.” I’ve never purchased a phone cooling fan before, but I decided to test its cooling performance with instruments. Within one minute, it was able to lower the temperature from 23°C down to nearly -4°C, which is impressive. (However, since the heat dissipation side of a Peltier thermoelectric cooling module is critical, if the hot side cannot effectively release heat, thermal energy will flow back to the cold side, severely reducing cooling performance. In my test, after about 20 minutes, the fan on the hot side had already reached its cooling limit, causing the cold side temperature to rise back up to around 10 °C.)It attaches directly to the back of the phone using MagSafe, making it very convenient. Charging is simple as well—you don’t need to remove the entire unit, just detach the battery and charge it via USB-C. Overall, it is extremely user-friendly and highly effective. I highly recommend it for anyone looking to prevent their phone from overheating.
It takes forever to charge. And when im using it outside it has to be on level 4 or lower if not it just turns off. I guess it only like to be indoors lol. I also dont like how the magnets aren’t strong enough and the battery comes off too easy
The battery is trash. Does in a day. The cooler is barely effective unless on max setting, and then it's very loud. Level 1-3 on the fan is bearable sound, then almost pointless for cooling.
Excelente
Doesn't do any type of cooling except for the one spot its in. Phone over heats regardless.
It gets cold 🥶
As a cooler, this device is actually pretty decent. The cold plate is large and all of it is chilled, not just a small portion of it. At max power (L7), this thing draws 5.25v at 1.9a, so around 10w power usage. For a 10w cooler, it performs better than I expected. The whole package also looks pretty cool, with a pretty clean RGB aesthetic. The lighting is rainbow and not adjustable, and the primary use I have for it is as a visual indicator of whether or not the cooler is powered on.However, the battery pack is a let down. I'm not sure what the advertised capacity is, but if using the cooler at L7, it lasts under 1 hour. Despite using a Type C connector, it charges at an extremely slow rate of around 3-5w (5v at 0.7a or so). This means it takes several hours to fully charge the battery, and it completely drains in under 1 hour.If you use the battery pack as a backup power source, while mainly using the cooler plugged in, then I think this product is decent. If you buy this cooler with the expectation to use it wirelessly all the time, then expect to spend far more time charging it than using it.Seeing as they aren't a lot of options when it comes to wire free phone cooling, this one performed better than some of the wired coolers I've used. However, I think people who would buy this is buying it because of the battery, so it's important to know what you're actually getting. The disproportionate charge and discharge rates makes the battery pack function less than ideal.
The battery that powers this fan/TEC maybe lasts an hour. Connecting power to the battery while mounted to the TEC only charges the TEC and not your phone.I wouldn't recommend it unless you are maybe traveling in a hot place and need something to cool down the phone while charging.
