Redmagic Cooler VC 6 Pro Cooler Review

Redmagic has a history of pushing mobile gaming performance. A history of seven years to be exact. Since its inception in 2018, Redmagic has been innovating with high-refresh ergonomic gaming phones with advanced thermal management technologies.

As mobile games become more and more hardware and graphics intensive, accessories such as Redmagic’s cooler series offer quick snap-on cooling to enhance the overall thermal management performance. I can speak to this with my firsthand experience primarily playing Call of Duty Mobile.

Historically, I’ve configured my graphics settings to “low” or “medium,” often restricting the frame rate to prevent my phone from lagging due to the heat buildup. The Redmagic VC 6 Pro cooler has introduced me to a no-compromise gaming experience.

However, like you, I’m curious to figure out what the observable improvements are. Note: emphasis on observable. While decreasing temperatures by 18 degrees Celsius within 10 seconds certainly sounds impressive, I want to figure out if this makes a difference? More specifically, is it a difference I can directly notice while gaming?

Let’s start by taking a look at the technical specifications and my unboxing experience. From there, we’ll dive deeper into how it has shaped my gaming experience.

The table below comprises both the technical specifications shared by Redmagic and my callouts to their advertised numbers when it comes to cooling and thermal management.

One thing I found interesting was Redmagic’s operating noise listing. It states that the operating noise is less than 35 decibels. As a sneak peek into my experience, this is a really quiet fan that you definitely won’t notice while gaming.

The Redmagic VC 6 Pro arrived in two boxes - the main box container, the cooler itself, and a secondary, black accessory box. I noticed that the box itself did not mention “VC” anywhere, while it did on Redmagic’s website.

My speculation is that “VC” is an additional detail in reference to the vapor chamber cooling technology. That being said, I don’t think there is any concern here since the aesthetics, look, and feel, and performance do not differ in any way versus the product page listing.

Let’s take a look at the second box, which is a clamp accessory that can be used with the Redmagic VC 6 Pro cooler for devices that do not have a magnetic attachment. For devices such as the newer Apple iPhone that have MagSafe, this clamp is not needed since the attachment is magnetic.

The back of this box contains an intuitive tutorial on installing this clamp to the Redmagic cooler and subsequently your device. Instructions are in both English and Chinese, but the pictures alone should explain everything.

I’m going to make a speculation and say that my particular package came with the clamp. However, your purchase may not come with the clamp, which will be totally fine as Redmagic included something in the main box to eliminate the need for this bulky clamp.

I have to admit that the clamp itself doesn’t have the most elegant design. While it isn’t heavy, the overall clamp feels quite clunky and does impact the ergonomics of holding your phone while gaming.

Again, I wouldn’t discount the Redmagic VC 6 Pro cooler on this clamp alone since I believe Redmagic has since solved this problem. We’ll take a look at how exactly they’ve done so when we unbox the rest of the contents and take a look at the main accessories.

Pivoting back to the main box, it’s aesthetically clean. The side view features a simple Redmagic engraved emblem. The back of the box contains the company address, product model, and serial number (which I have blanked out).

While warranty information isn’t mentioned on the box, I do like how the service hotline phone number is directly listed. After doing a bit of research and cross-referencing Redmagic’s website, accessories such as the VC Cooler 6 Pro come with a six-month warranty.

After opening the box, we’re greeted with the Redmagic cooler first. It’s aesthetically pleasing to see a durable fan construction. While it looks smaller than what I had anticipated, it packs a powerful punch, which I experienced first hand later on.

As I continued to unpack this box, I found the accessories underneath and sandwiched in between the foam padding.

For a simple cooler for mobile gaming, I was surprised by the amount of accessories included. Always nice to have, the user manual provides instructions for the other accessories, especially the magnetic sheet.

The magnetic sheet, which is as thin as a sticker, solves the bulky clamp design I mentioned earlier. This installation is outlined in the user manual.

To prepare the surface for the magnetic sheet, Redmagic also included a single-use alcohol wipe. This will clean the surface and ensure a strong adhesion for the magnetic sheet.

Finally, Redmagic includes a USB-C power cable. I’m always glad to see this as some accessories may require you to purchase your own cables.

Let’s take a closer look at the magnetic sticker. This is a square sticker, measuring less than 0.5mm thick. Based on my iPhone’s measuring tool, the dimensions come out to 7 cm for the length and width. This matches the “cooling” surface area of the Redmagic cooler itself.

This magnetic sticker essentially replaces the need to use a bulkier clamp for devices that do not have a built-in magnetic attachment, like the iPhones with MagSafe.

Simply attach the magnetic sticker to the back of your phone or case, and the Redmagic cooler will magnetically attach itself to this sticker.

While I really like this solution over the clamp, I think there are a couple of considerations. The first is that this magnetic sticker is likely single-use only. Once it has been installed onto your phone or case, the adhesive will likely lose its effectiveness if you peel the sticker off to re-stick it to another surface. Definitely think carefully before you install this sticker.

The second consideration is that this sticker is quite rigid. Although it is thin, it also does not bend easily. If your phone has a curved back, this may impact the effectiveness of the adhesive side. This will likely only impact you if you’re looking to install the sticker somewhere slightly off-center.

The final consideration is that there’s still a bit of thickness with this sticker. While I do think it’s quite thin, it’s not nearly thin enough where you can sandwich it between a phone case. In other words, do not install the sticker onto your device and then put a phone case over it. The thickness of the sticker will definitely put additional stress on your phone case.

If I may offer Redmagic a suggestion - it would be nice if Redmagic included more than one magnetic sticker. Having a spare for backup in case an installation goes wrong would be ideal.

That being said, Redmagic does go into detail in the user guide.

The first page of the user guide outlines the different components of the Redmagic cooler. The top of the Redmagic cooler is primarily the air intake. Of course, it does have customizable RGB lights embedded in it.

Make sure to note the power input requirements in the technical specifications section. The input requires 15V at 3A current. Most modern USB-C wall adapters are capable of this, but you may need to upgrade yours if you have an older wall adapter.

The bottom of the Redmagic cooler features a silicone refrigeration surface. This surface has magnets embedded in it. My speculation is that this magnet array is circular to match the iPhone’s MagSafe configuration.

If I were to use my phone without a case, the Redmagic cooler has perfect or near-perfect alignment.

Over on the second page of the user guide, we take a closer look at the attachment and usage. If your phone does not have magnets embedded, you’ll need to install the magnetic sticker on your device before you can use the cooler.

I thought it was also pretty cool that there’s a Redmagic app you can download in order to customize the RGB lighting. I was surprised by this as I initially thought the RGB lights were pre-configured and could not be changed.

Let’s take a look at the Redmagic cooling unit. This part of the review may get confusing because there’s an additional port on the Redmagic that isn’t often talked about.

This section of the review is a combination of my observations firsthand along with my research. Immediately looking at this unit, there’s the “Redmagic” logo situated in the middle of the fan. The top is ventilated to draw in air that will be used to cool your phone during intense loads such as gaming.

On the bottom, with the red arrow, is a USB-C port. This is the power supply port, designed to power the fan and cooling system. With that in mind, this means you can orient the Redmagic cooler however you wish.

Depending on what’s comfortable for you, you can make this power supply USB-C port point downwards or upwards. This is useful since you may choose to connect the USB-C port with a cable that runs to a wall adapter rather than a more portable power source such as a power bank.

The top of the Redmagic cooler unit is also quite straightforward. It features a red switch that can be toggled on or off. This power switch is controlled by sliding it left or right. It is not a button where you press down.

Now you might be wondering - why would you even need this switch? My observation is that this cooler is quite powerful and your device could potentially run really cold. If heat has been dissipated, you may wish to temporarily disable the cooling fan until there’s too much heat build-up.

The side view is where I think things get confusing. The Redmagic VC 6 Pro cooler has a second USB-C port that is labelled “For Wireless Charging.”

There’s also a warning sticker just below it that says, “The Type-C port (blue) is for wireless charging only and should not be used with an external power source.”

If you think wireless charging in the literal sense, you, like me, probably thought that this cooler can also charge your phone at the same time. Unfortunately, this is not the case. Apparently, there’s a separate attachment that can enable wireless charging while cooling your phone.

However, it seems the wireless charging attachment cannot be found anywhere. At least, my research did not yield any credible results. I’ll touch upon this in the next section.

The bottom of the Redmagic cooler features a unique material that can be described as having a rubberized texture. This is the graphene pad that’ll dissipate heat while transferring the cold air from the cooler to your mobile device.

This graphene pad is a little bit of a dust magnet, which I would’ve liked to see Redmagic provide more guidance around its maintenance. While I tried to keep this pad clear of dust during my testing and usage, there were some dust specks that managed to linger. So far, it doesn’t seem like this impacts the actual cooling performance.

I’m dedicating a section to talk about the wireless charging “feature” on the Redmagic VC 6 Pro cooler. This is the one feature where I did a lot of research on, consulted third-party websites, and looked at mentions from other users. At the end of the day, I don’t have a concrete answer, so please take my experience with a grain of salt.

The blog post from Nubiamart is probably the most reliable source regarding the wireless charging attachment. This is an attachment that you can pair with the cooler, and they connect together via a USB-C adapter.

Think of it this way - the Redmagic VC 6 Pro cooler connects to a power source via the red USB Type-C port. Then a smaller c-hook USB Type-C adapter connects the cooler via the blue port to a wireless charging pad.

This way, there’s one power supply to simultaneously cool your mobile device while charging your mobile device without the need to plug in a separate wire.

Nubiamart shows off this attachment. I tried to find an e-Commerce store to purchase it but did not have any luck. Interestingly, Redmagic’s official website does not list this accessory.

Based on my research findings, I have a few speculations. It’s a great accessory in theory, but demand is low. When the cooler dissipates heat buildup in your mobile device, it performs more efficiently and slows down the battery drain significantly. The added weight and bulk of the wireless charger versus the actual charging speed may be a tradeoff that’s not worthwhile.

When you combine all of these factors together, I can see why Redmagic decided to discontinue or cease promoting the wireless charging accessory. However, this is a disappointment because there are times when users can benefit from this combination without gaming. For example, I can see the benefit of wirelessly charging my device while simultaneously dissipating heat, especially given how prone heat buildup is with wireless chargers. I do hope this accessory will be released sometime in the future since my own testing indicated clear benefits.

So, how well does the Redmagic cooler perform? Since my review focuses on real-world observations, I conducted two tests that seemed most relevant.

The first test involved charging my iPhone 15 Pro Max using an Anker MagGo 10K Power Bank. I wanted to see if the Redmagic cooler could effectively dissipate heat from the wireless charging source and whether it shortened the charging duration to full.

For the charge test, I opted for the MagSafe power bank instead of my MagSafe charging puck because the built-in LED display would allow me to monitor the battery percentage. This way, I could easily identify any significant variations.

To dissipate heat, I positioned the Redmagic cooler at the center of my iPhone’s screen. Surprisingly, I noticed a noticeable difference in the charging process.

There was definitely a noticeable difference when using the Redmagic cooler. Charge Test 1 “failed” because my iPhone paused charging at 80% because of the heat build-up from the wireless charging.

On the other hand, Charge Test 2 successfully completed from 12% battery to 100% in 1 hour and 56 minutes. The Redmagic cooler did its job to dissipate heat and ensure that my iPhone remained within operable temperatures.

The Redmagic cooler’s performance becomes very noticeable during intensive gaming, which you can directly observe in the below screenshots.

As a big Call of Duty fan, I naturally play Call of Duty Mobile, follow the new in-game updates, and grind my way for weapon upgrades. For the longest time, I kept my Graphics Quality and Frame Rate settings to “Medium” because I noticed a significant performance drop when my iPhone experienced heat build-up. This usually occurred after 30 minutes of gameplay.

This is frustrating because I find myself having to exit the game and restart the app in order to “reset” and get the full frame rate back. And all of this is on “Medium” settings.

While using the Redmagic cooler, I’ve drastically increased my settings to “Very High” for both the Graphics Quality and Frame Rate settings. After 30 minutes of gameplay, my iPhone remains icy cool and I experience no slowdowns. To me, this is a clear improvement where the Redmagic cooler does a great job of enhancing performance under sustained loads.

Even with a case, the Redmagic cooler attaches to the back of my iPhone magnetically without any issues. For me, the magnetic sticker remains in the box as a just-in-case if I ever switch to a device that does not have MagSafe.

The Redmagic VC 6 Pro cooler isn’t going to benefit the casual gamer. If you’re waiting at a doctor’s office or by the bus stop, it’s not going to change your gaming experience in the span of 10 minutes.

However, the difference becomes very noticeable when you pivot over to graphic-intensive games such as Call of Duty Mobile or the Asphalt racing series. The Redmagic cooler is a must-get accessory in order to achieve a no-compromise gaming experience.

In general, heat is a killer for your phone’s battery health. Keeping the temperature under control is also a key benefit to extending the longevity of your mobile device. After all, this can be observed through the failure of my first charge test.

The wireless charging accessory will continue to remain a mystery, but I think Redmagic is moving in the right direction by introducing the magnetic sticker to replace the bulkier clamp design.
