Hagibis Magnetic Cell Phone Cooler Ultrathin Cooling Fan Portable Lightweight Mobile Phone Radiator for iPhone 16 15 Pro Max, MagSafe Series, iPad Pro, Android, Tablet (Black)

UPDATE: since my review, I purchased the recently released “Pro” MC100 SSD enclosure. What separates it from the unit I reviewed: a third USB port. This third port is USB2.0 speed and power, advertised as a USB mic port. It also provides the fan enough juice but only when connected to external power. If you need to run the fan and SSD combo, the MC100 Pro is the only one that will support it. However…What I’ve discovered is that my gen4 x4 m.2 SSDs don’t run nearly as hot in these enclosures as I was expecting. With 10Gbit xfer chips in the enclosures, my SSD is hardly breaking a sweat to saturate the bus. Even the optional static cooling fins seem to be overkill, even when recording long form 4K24 bRAW.Because of this, I find access to the MagSafe array on the rear of the SSD enclosure far outweighs using either cooling solution, at this point.Original review below:A nice sink and fan with 3 speeds but no off. A tiny button next to the USB-C port controls the fan speed and there are no distracting indicator lights. The fan and TEC draw too much voltage to be powered by my iPhone 15 PM; YMMV.What’s a TEC? Thermal Electric Cooler, aka Peltier cooler. It’s simply a powered, thermal conductive plate that pulls heat from one side and transfers it to the other.The back of the heatsink has a MagSafe array that holds well enough, with a silicone cover to protect your iPhone’s back glass.For the best performance, use only when directly mated to the Hagibis MagSafe SSD housing or iPhone without case. Any case will significantly diminish the TEC’s cooling performance.What separates this from the rest? It’s smaller: at 1cm thick and a diameter matching their SSD housings, it will not impose on your video recording, even when stacked atop an SSD, while using the ultra-wide camera. YMMV. It also has no lights. None. No status indicator or RGB disco array: this is designed to keep your iPhone or SSD cool while recording video to an external disk and disco lights ruin recordings.You can use this for gaming but it’s been designed to serve photographers/videographers.

I love the design, the fit and it’s a sleek little fan that goes with the SSD enclosure by Hagibis.Problem is that it will not power itself by use the usb c, you need a separate power source and need the SSD enclosure with three USB C outlets(third outlet for power).I have the one with only two. Once I get this worked out I think it’s a great fan and as a stand alone phone cooler I think it’s solid.

Works very well, just remember that it doesn't charge the phone!

I am mixed about this one. Specifically because in order to use this, we cannot have a metal ring to hold the phone. Most people have a stand or a ring on the back of the phone and this isn't compatible with a case that has a ring embedded. The metal ring is still not strong enough for the magnet on the cooling fan. The fan is very quiet almost to the point that I couldn't hear it at all. I did test to see if I could hear a difference based on the speed and I was unable to detect it. I can confirm it does a great job cooling as long as the fan is not blocked. This also requires that the fan is receiving constant power as it doesn't have a rechargeable battery as part of the fan. This is fan is designed for people who are not mobile and sitting in a stable location.

This thing really surprised me. I thought it would work more or less like a laptop fan, but when I lifted it off the back of my iPhone (MagSafe compatible/magnetic) the bottom of the fan and the back of my iPhone was ice cold. Not sure how it gets it that cold but it does. It does need power for it to work but that’s not really a problem for me.

I get a warning that this accessory uses too much power and it will not turn on at all.

4 stars only because when used with the Hagibis MC100 pro NVMe enclosure as advertised on the MC100 page, the ssd is not functional.SSD is functional with the cooling fan when you plug in charging power to the PD port of the SSD.

Who would have thought that you could get a Peltier cooler for $17? Not me! I was pleasantly surprised by how well this works!The magnets are strong and keep it in place on your MagSafe compatible phone/case -- I tested it using my Pixel 9 Pro XL and powered it with external power (you can use any USB-C PD capable power source). Once I had it running, it kept my phone cooler during long periods of playing games, much more so than if I just had the phone bare. There is a noticeable difference in temperature between how the phone feels in your hand with this thing on and without it.The unit can hot if you don't have proper airflow as one side gets cold and the other is hot, which is why there's a small fan and aluminum heatsink on one side. Make sure it has ample airflow and it'll keep working.Most people probably don't need this but if you do a lot of gaming, media work, filming, etc. on your phone -- this thing can be worth it to keep things cooler. It's only $17 and I can say that it's definitely worth the money to try out!
