TRILINKMagnetic Phone Cooler with Wireless Charging, Phone Cooling Fan for iPhone/Android/iPad/Tablet - Phone Radiator for Gaming, Compatible with iPhone 12/13 MagSafe -RGB LEDs - Universal Clamp

The media could not be loaded. I got this thinking was just a magnetic, passive fan. It's a bit more than that. This actually contains one of the solid state heat-pump devices (piezoelectric cooler?) to transfer heat from the contact surface to the fan to be dispersed. There is no on/off switch on this. It automatically turns on if it detects a phone capable of wireless charging and turns off when disconnected.Note that this version has no battery. You must connect it to an external power source for it to operate.It connects to the magsafe area on an iPhone. On other phones, there is a mounting clamp for attaching it to the bak of the phone. Works best if in direct contact with the phone (no case).

Bought 2 since the first worked in August and both failed by October. Same symptoms as others; shows an 88 on the display no charging and no fan.

Charging and cooling work well. However, the lights and fan do not turn on or shut off based upon a charging connection. Both turn on when connected to usb c power and run constantly, irrespective of whether it is charging a phone.

The product name says “radiator” which I guess you could argue is technically true, but the 2nd photo labels the ring of fins as a “heatsink.” That ring of fins is plastic, not metal, they don’t absorb or dissipate heat at all.The only cooling here is done by the weak Peltier cooler and the loud fan that helps disperse the heat that the Peltier produces. It charges the phone fine, but it’s just barely enough cooling to counteract the heat created by that wireless charging.This is better for the phone battery than a normal wireless charger, but don’t expect it to improve gaming performance or anything. The LCD is pointless, it displays some kind of power scale I guess; it always starts at 2 at first and ramps up to 11, then ramps down again when the phone is fully charged. It barely keeps the phone at room temperature, and I don’t even use my phone while it’s charging.I’ve tried 3 different cables including the one it came with and an Apple USB-C to C, in every combination with 3 different wall chargers including a 65w Anker, 20w Apple, and a generic 33w. It’s not a power delivery problem, it’s a fake heatsink problem.

I use this to keep my iphone cool while streaming softball games all day at the ball park in 90+ heat. The phone stays surprisingly cooler than I expected and I have eliminated all of my overheating issues. Really appreciate that it charges the phone as well so it can go all day.

Update-The customer service reached out to me and sent a replacement. This time it works perfectly.——————————————Original reviewThis cooler/charger has good looking. However, I charged my iPhone only twice and found out it didn’t work with burning smells.

Device will barely charge but not cool the phone.

My unit is only charging my iphone 14 pro max at 10w. Battery at 83%. Still havent tested the cooling aspect but it noticeably weaker than the black shark. About 1/3rd if i had to say. The size is perfect only a tad bigger than the black shark but the performance just isnt there at first glance. Will test it with some games and see what happens.
