The new Aspire MIXX is another collaboration this time with Sunbox…looks like they like working ‘side by side‘…

I said on our Vaping Christmas update that what I was hoping for in 2020 was a return of the Side by Side mods.

Aspire Mixx review

Well, seems like someone at Aspire was listening to me, because they have partnered up with Sunbox to come out with Mixx.

In fact Side By Side mods seem to be making a bit of a comeback generally, proving once again that the vaping industry goes in cycles and what was old is new again!

What Can We Expect From The Aspire Mixx?

Aspire are a Chinese company formed in 2013, and whilst not as prolific as some vape companies, what they have produced has always tended to be quality.

Some of their most successful designs have been the Cleito range for sub-ohm vaping, starting with the original Cleito which Jonny gave full marks to in 2016.

Also the Nautilus range that was focused on mouth to lung vaping and still uses the same coil design many years later. Jonny also reviewed the original Nautilus way back in 2015!

More recently they’ve had some good feedback from Gaz for the Cloudflask, Neil who looked at the Rover 2 Kit and the Harley who reviewed the Nautilus GT Kit.

Like the Nautilus GT Kit, this is another collaboration, built by Aspire with a high end designer adding their flare!

This time it’s Sunbox, a mod maker from Italy. They’re probably most well know for their side by side designs, so it’s no surprise to see that this is the design that Aspire have gone for.

In fact this is the second collaboration Sunbox have done recently, they previously partnered with Ambition Mods for the Easy Side By Side.

The Aspire MIXX is a different beast though. Made of CNC aluminum and stainless steel, the Mixx is a very solid single battery box mod.

So does the “Mixx” of Aspire and Sunbox tick all the right boxes?

Let’s find out!

This was sent over to me free of charge from Aspire (thank you). As usual this will not affect my review in any way, and I shall report back honestly on what I find.

Aspire MIXX Packaging

As is usual for Aspire, the packaging is top notch. With their collaborations, they show off even more, and this definitely has the feel of a high end piece when you remove the lid and see it sat there.

Aspire MIXX Colours

Aspire has created three colours for the Mixx:

Jet Black, Quick Silver and the one that I received, Tuxedo.

Aspire Mixx Colourways

As you can see, the Tuxedo is a mix of the two, with the main body being black, the battery tube and the controls in silver, and weirdly the battery cap in… gold!

Aspire Mixx Gold Battery Cap

No, I have no idea why they went with gold for this one either!

Battery Cap

Now I know that some people don’t like screw on battery caps, as they are certainly a little slower than a hinged door when it comes to changing your batteries.

On the plus side, with no spring to take up slack, you don’t have any of the voltage drop a spring would introduce, and obviously you can totally eliminate battery rattle.

Aspire have done good work on the cap, and it’s easy to get a grip on it to screw it in or out.

You can at least buy the battery cap separately, so if the gold irritates you, you can switch it out for a black or silver. Personally I think it would have looked a lot better as silver.

That’s not the only colour oddity about the Tuxedo though.

The 510 plate on the Black or Silver is matched to the colour of the mod.

On the Tuxedo, it’s silver on a black body. It’s not a major thing, but you might notice if you use a small (22mm) black tank, as there will be a silver ring around the bottom.

These are only issues with the Tuxedo version, the other two are totally colour matched.

Aspire MIXX Body

“Solid” is the first word that comes to mind when you pick the mod up. The main body of it is CNC machined out of a solid block of aluminium.

Apparently this takes 30 minutes per mod!

This is not the first time aspire have used CNC, as well as the standard zinc alloy NX75, they also made a CNC aluminium model, and a stainless steel one.

As well as there CNC’ed block of aluminium that makes up the most of the mod, you also have a steel base plate, and a steel battery tube that rises up and has another piece of aluminium screwed on at the top.

Aspire MIXX Base

On the base is the “Designed by SunBox” and regulatory marks, and this is also where your screen is.

Aspire MIXX Battery Tubes

Now this is something you don’t see that often!

As well as the battery tube for a standard 18650 battery, you also have a battery tube for the much smaller 18350 battery.

It’s simple enough to switch between the two, but it does require the use of an Allen key.

Amazingly Aspire doesn’t include one of these in the packaging, not an issue for me, but it would be irritating if you don’t already own a large selection of different sized Allen keys!

  • To switch between the two you need to first unscrew the two long screws that are on the midline of the mod

Aspire Mixx Unscrewing Long Screws

  • Remove the top metal section
  • Unscrew the battery tube from the base
  • Screw in the new battery tubeAspire Mixx Screw in 18350 Tube
  • Place the top section back
  • Use the smaller screws to screw this down to hold it in place

Aspire Mixx Tighten Shorter Screws

As you can see this is now a much smaller device!

Aspire Mixx 18350 Mode

Aspire Mixx Screen and Controls

It’s a 3 button mod, with your fire button in a nicely shaped cut out on the front, and your plus and minus buttons (unmarked) on one side.

As with a lot of Sunbox mods, the screen is on the bottom. It’s a bright 0.91″ OLED display and it shows all the information you need, the resistance of the coil, volts, amps being drawn, and battery life.


One slight criticism I have is that it only shows the volts and amps whilst you are pressing the fire button. Returning to 0 the moment you release it.

Especially with a bottom mounted screen, I wish it would remain displayed for a second or so afterwards so you could glance at it after vaping.

Aspire Mixx Vape Modes

You only have 3 different modes run by the Aspire ASP chip on this one: Variable Wattage, Variable Voltage, and Bypass.

I think that’s enough personally, and I’m quite a fan of the bare bones approach!

Wattage ranges from 1-60W and scrolls in whole watt increments when you hold it down, or 0.1 increments for individual button presses.

How Does the Aspire Mixx Perform?

Atomizer Fit

Side by side mods always require some thought when it comes to what atomizer you’re going to put on it.

Aspire say that it will accept up to a 24mm tank, however if you really want to, you can get a 25mm tank on.

Top Section removed and 25mm Tank

What you need to do is remove the screws holding the top section of the mod on to the bottom and take the top section off totally.

This is not recommended, as you are relying on just the threading on the battery tube holding everything together, but it is possible.

As well as width, you also need to be aware of your atomizers height. If you’re atomizer is too short, then the drip tip may well end up below the top of the 18650 battery tube.

30mm is the minimum you want from the base of your atomizer to the start of the drip tip. Though obviously if you use it in 18350 mode, you can get away with as short as you want.

Aspire Mixx Battery

The biggest possible change in battery life here is going to be whether you’re using an 18350 or an 18650. Using an 18650, this would easily get me through a whole day of vaping around 20W.

In fact I’d go so far to say that it’s a shade better than some other recent single battery 18650’s, so Aspire has done good work with their ASP chip.


Switching down to an 18350, and you’re obviously going to have a much shorter battery life. I tested it out a few times, and whilst it would last me through an afternoon, it couldn’t carry on much longer.

As with all battery components on a removable battery mod, a lot of it is going to depend on other factors. Which batteries you’re using, what wattage you’re running at, etc.

But 18350 batteries rarely get much above 1,000mAh. Whereas an 18650 can easily be 2,500mAh or higher.

Controls in Use

There’s a couple of things that I really appreciate with the control set up.

Firstly you can totally power off the mod, rather than just lock it, of course you can slightly unscrew the battery cap to cut the contact as well.

Secondly you can flip the screen. It might seem like a small thing, but it makes a real difference in use!

Firing seems to be pretty instantaneous, so absolutely no complaints on that front.


  • Beautifully constructed
  • Choice of 18650 or 18350


  • Slightly odd colour choices on the Tuxedo
  • No Allen key included to change battery tubes
  • Screen only displays amp load whilst being fired

Final Review Verdict

I’m really pleased to see the return of the side by side box mod.

It’s a design of mod that I was worried we were going to see consigned to history (except for the uber expensive ones by high end modders).

Aspire has done a great job at taking a classic design and updating it.

Whereas most side by sides were limited to 22mm, by taking it up to 24 they’ve updated it to take a newer generation of tanks.

It’s still a relatively basic piece of kit, no Temperature Control, no power curve, and no weird menu items.

However, it does what it sets out to do with aplomb.

Accurate and fast firing in Wattage, Voltage or Bypass, and with a maximum wattage of 60, it can handle a small sub-ohm tank quite happily.

Although I tested it extensively with the Aspire Nautilus GT Mini, I also tested it with the Aspire Nautilus GT.

And you know what? I think that’s pretty much a perfect combo.

The stainless steel Nautilus GT has an ultem drip tip, which even makes some amount of sense with the gold battery cap!

Are you a fan of side by side mods?

Is this one you’re keen to buy?

I started my vaping journey in 2017 with a little AIO kit. I’d made several attempts to give up smoking over the years, and I finally nailed it with vaping. I knew right away that I wanted to learn as much about all these devices as possible, and I quickly got into rebuildables and replaceable battery mods. I’ve always enjoyed kit and technology, so I’ve built up quite a collection of different tanks and mods. I love knowing how things work and what to do to get the best out of them, so sharing that knowledge and helping more people quit smoking is something I’m passionate about.


  1. Really useful article and now I’m about to purchase a Mixx based on it.
    Almost everything else I’ve ever seen only ever refers to the Mixx in a sub-ohm context but I wanted something for mostly MTL so had discounted it.
    Just to confirm, can I definitely use it (with the correct settings of course) for both?
    Sorry; I’m a newbie.

    • Hi Nik, thanks for reading the review and I’m glad it was useful!

      You can definitely use the Mixx for mouth to lung. MTL is my preferred style of vaping, and the Mixx suits it perfectly. I’ve got it paired up with the Nautilus GT and it’s a lovely mouth to lung combo. To be honest when it comes to a mod, you can use almost anything for mouth to lung, even massively powerful dual 21700 mods can work absolutely fine, as you’re just using a lot less of the available power.

      The only thing to be aware of, as with any side by side, is going to be the size of the tank that you put on it. Obviously you’re limited to 24mm in diameter, which is fine for MTL as so many tanks are 22mm. But you also need to be conscious of the height. If you were to get a very low profile tank on there, you might find it a bit weird. So long as your tank is at least 35mm (excluding 510 and drip tip) you’ll have no problems. Even shorter is possible, but you might want to use a long drip tip.

      Off the top of my head I can’t actually think of any tanks that would be noticeably too short, it tends to be drippers that you’d have to be conscious of.

      Hope that makes sense, and if you’ve got any other questions feel free to ask them!


  2. Thank you for the review Sir,
    May i ask what number of allen key you use to open the battery tube screw? It is hard to find the match. Thank you.

  3. I love this mod, I bought the Jet Black one and a Silver one. Put the SS tube off the Silver one on the Jet Black one and paired it with my SS Dvarw DL FL. Perfect and suuuuuper sexy.
