Razer Phone Cooler Chroma: iPhone 12 & 13 Series – MagSafe Compatible – Advanced Smartphone Cooling Technology – 7-Blade Fan – 12 RGB LEDs – USB Type-C Power Cable – Powered by Chroma RGB

Great Cooler, Magsafe Convinient for iPhonbe. TL;DR – This is great if you’re an avid mobile gamer and have realistic expectations of what it will do.First things first. I want to address some things that reviewers have been saying. When buying a product, you need to have realistic expectations. I’m seeing people saying things like: “I wish it was battery powered” “I wish it would charge your phone” “I wish it would cover more of the phone” “I wish it was smaller”. You can’t buy a product and expect it to do certain things that not practical. That’s like saying “I wish my screwdriver could also hammer in nails, drill holes, and also charge my phone.” This product serves a specific purpose and there are going to be limitations due to engineering.Let me cover some of these complaints:-You can’t have it be battery powered and/or also charge your phone at the same time. Why? Because having a battery will make this thing bigger (already a complaint by some, I will address this below) and having it also charge your phone through Magsafe introduces heat, which goes against the purpose of the product. Additionally powering a fan like this consumes a lot of power. I really doubt a tiny battery pack inside this product would be enough to keep it going at high speeds for a couple hours.-Could they have designed this to cover more of the phone? Possibly, but you’d need more fans and a bigger heatsink. Additionally, there are so many phones on the market and they are all different sizes that it’s really not practical for Razer to do this. You’d have to create a cooler for so many different phone models and this is a niche product. “One size fits all” is a much practical solution.-Could it be smaller? No, the bigger the fan and heatsink, the more heat you will dissipate. If the fan was any smaller then this wouldn’t work. It’s plain simple physics. You can’t cool more surface area than you are covering.Now that I have that out of the way, on to my review.Who is this product for? If you are an avid mobile gamer that plays demanding games, then this is for you. If you’re not then you don’t need this. I’ve tried a LOT of different coolers. I’m still on the search for the perfect one, but this one I have to say is pretty good.PROS:-This DOES cool down your phone. The things that mainly get hot (besides GPU and CPU) on phones are the battery and the screen. Once heat is introduced, phones start doing things to limit the amount of heat. One of the most annoying is the screen being shut off. This definitely resolves that.-I have the Magsafe version which is really convenient. I’ve tried other coolers with a clip, and they always get in the way.-This item DOES NOT charge your phone, but you can still plug in your phone to charge while using it. If you don’t like having two cables, you can always buy some other coolers that have a daisy chain from the cooler to your phone to charge.-You can power the cooler with a power bank.-You can use a Magsafe case with this, but you’ll get best results with direct contact to the phone. However, if you do plan to use it with a case, use one that is solid and doesn’t have a cutout for the Apple logo. If you use the latter then the cooler is useless since these type of case leaves a few millimeter gap between the heat sink and the phone, thus rendering it useless.-This keeps your battery from getting hot as you game. Since heat is one of the things that kills your battery, and since Apple throttles your charging speed when the battery gets hot, I like to put the fan on when I charge my phone so it charges the battery faster. When I play, I’ll charge my phone to a certain percentage, unplug it and keep the fan on to keep it cool.-I like the fact that Razer has an app for this. You can customize the lighting, fan speed, and even see the temperature. This is something I don’t think any other phone cooler has. I noticed there’s a firmware version for the cooler… I’m hoping for more improvements in the future. If this is so, then this definitely is something that puts this cooler above others.CONS:-Most of the cons I’ve already listed in my intro which really comes down to engineering limitations and decisions. There’s going to be things you have to sacrifice in order to get a certain amount of performance. Weigh those things out and then decide if this is the product for you.-This doesn’t really cover the CPU on the iPhone which is unfortunate, but understandable. If you’re using this for any other phone you might get better results depending on where the CPU is, especially with the clip on version. I bought this because of the convenience of Magsafe.-Annoying, but by default the cooler shuts off when the temperature reaches a certain threshold. You have to flip the switch to off and then back on to reset it. You can turn this off in the app, but at first I thought the cooler was broken. This isn’t very intuitive and in my opinion this feature shouldn’t be default. Seems like this behavior can be solved with a simple firmware update; I did notice there is an “auto” setting for fan speed. Why not just have the fan go slower instead of the whole thing just shutting off? Or have it so it’s “on” but the fan doesn’t spin and then have it spin when it gets hot? I’ll have to test this more.Overall, this does what it says it does: it keeps the phone cool. It keeps the battery and screen from overheating, which drastically improves quality of life while playing, and also the overall health of your mobile device. If the whole phone gets hot, this heat transfers to the CPU and GPU, so even just cooling the parts of the phone that it does really does help. Having an app is great, I am hoping this will mean firmware updates with added features from Razer in the future. If your main source of gaming is on your mobile device and you spend a long time playing demanding games, then I highly recommend it. Otherwise it won’t really be of much use to you.

nicely designed cooler. convenient form factor, benchmarks say it cools at least as well as competitorsit isn’t obvious the fan speed depends on the charge. I initially plugged it into a pc usb port and it spun slowly. I thought that was it. When I went afk and switched it to a portable charger, that’s when I found the max speed is a lot higher. It seems to work well. Hopefully it prevents heat based disabling of iphones.

Investment, rather then spending. Although there are other coolers available for cheaper, Razer’s performs better and feels more premium. When turned on, the backside immediately starts to drop in temperature, and reaches its lowest within a minute. The fans also provide extra airflow to the sides of the phone that aren’t being actively cooled, making the entire phone chilled. The MagSafe version has extremely strong magnets, and doesn’t slip off. Because it doesn’t use a clamp, you can adjust the cooler by simply twisting it however you need to. Aside from the temporary cooling, the decrease in temperature increases performance in all areas, and allows the processor to run harder. Long term, the decrease in heat will prolong the phones lifespan, as heat degrades batteries faster then would otherwise.
