One of Aspire’s NX range of mods is the Aspire NX75, which is a single 18650 mod packed with features, but is also tailored for easy use by those not interested in taking advantage of its more complex features.
There’s an interesting magnetic slide out battery door, which you put your 18650 battery into before inserting it into the device, plus temperature control support and 75w of power too.
The other mods are the smaller Aspire NX30 and more recent NX100. The latter of which takes a 26650 battery.
Aspire seem to be on a bit of a roll lately with some great product offerings, the Nautilus 2 tank (excellent), the Aspire K2 starter kit (excellent for new vapers), the Aspire Archon, a great TC mod that suits intermediate to the experienced and the latest Zelos mod that I have been using for a couple of weeks and looks like another good addition.
Let’s take a closer look and see how the NX75 matches up.

Design and Build Quality
The Aspire NX75 is manufactured from aluminium alloy, and it has white, black, stainless steel or red finishes available.
It measures in at 75mm x 37mm x 22mm, making it a pretty small vape device.
It has a pretty stylish and understated boxy design, with no flashy logos or colour contrasts. Not everyone’s bag but a styling I personally like. 
It’s a functional, straightforward and simple design that manages to look very elegant.
You can also purchase special editions that are manufactured from stainless steel or aluminium alloy, which give an even more premium feeling to the Aspire NX75.
There’s a spring loaded 510 connector, which eradicates gaps between your mod and your atomiser, if you have a 22mm atomiser sitting atop the NX75 it will have no overhang.
Screen real estate has been maximised at the side of the NX75, with an OLED screen that is crisp and easy to read.
As standard, it will display:
- Your current wattage or TC setting
- Power setting
- Temperature limit (if in TC mode)
- ‘Aspire’ (which can be customised to display a different message if you wish)
- Whether the device is locked or unlocked
- Resistance
- Battery level
There’s a lot of information displayed here! Firmware can also be upgraded via the USB port on the side of the NX75.
Buttons are a decent size and are responsive too.
You have a power button, a ‘W’ button to switch power modes, a ‘T’ button to switch between temperature control modes, as well as plus and minus buttons to make selections within the above.
A sliding magnetic battery door is present, the style of which I haven’t come across before.
You slot your 18650 battery into the door itself, then slide that back in.
It has to be said, while I actually like the way this works you need to be very careful when inserting batteries.
I found it was easy to get the wraps on the batteries caught causing tears. This can be potentially very dangerous so take care when putting your batteries in.
How Does The Aspire NX75 Perform?
One of the more interesting features with the Aspire NX75 are the Customisable Firing Button Profiles.
With these, you can customise a power curve which is displayed on screen, and set different wattages to kick in at set times.
It’s an interesting little feature which allows you a different way of tailoring the vape to your own style.
Power output ranges from 1-75w, which can be finely adjusted in 0.1w increments.
There’s plenty of power there for a single 18650 battery device, and the NX75 can fire resistances as low as 0.1ohm in wattage mode as well.
The power delivery in wattage mode is stable and reliable, and I haven’t run into any issues when using the NX75 in power mode.
Battery life is pretty decent, as long as you aren’t vaping over 45W.
I found that I would get good battery life under 45W, however above 45W the battery life decreased quickly no matter what my coil resistance was.
It wasn’t particularly great in temperature control mode either, which seemed to place a heavy drain on my batteries.
You can use Ni200, Titanium and SS316 coils in temperature control mode, and there is also a custom TCR input allowing you to input the TCR’s of different TC wires if you wish to use them with the NX75.
I tested all three coil types out on the NX75 and found there was a very stable experience, with no resistance issues or power fluctuations.
What I Liked
There are a ton of features packed into the Aspire NX75, you really do get a lot for your money here.
You don’t have to dive into advanced features such as the Customisable Firing Button Profiles or TCR for example, but they are nice features to have there in case you do fancy experimenting and fine tuning your vape.
The build quality of the NX75 is excellent. It sports a stylish, boxy feel to it, and it’s comfortable to hold as well.
The finish has held up well to day to day use, and I have yet to get a single visible large scratch on the mod. Battery life was very good when paired with the Aspire Nautilus 2 at around 16W.
What I Didn’t Like
The slide out magnetic battery door is a great idea, however you have to be very careful with your batteries as they can catch on the device and tear the battery wrap, which is potentially dangerous.
It has happened to me on two occasions now when I’ve been careless!
As it is a single 18650 mod, it’s not ideal for out and about use at 45W and over, as battery life can be pretty limited.
Unless you fancy carrying around a load of spare batteries in your pocket, if you vape at 45W and over then you’ll probably want to stick to using this device at home only.
Final Review Verdict
What Aspire have done here is they have managed to produce one of the best 18650 battery mods on the market today.
The machining on the device is excellent, the slide out magnetic battery door cover is ingenious, it’s packed with features and it has up to 75W of power too.
Looks wise I’ve got to say I’m a big fan, and it’s a comfortable device to hold and use.
Aspire have hit a home run with the NX75 mod, there’s a whole lot of upside and virtually no downsides to this device at all.
I highly recommend it, the NX75 is not only up there with my favourite mods of 2017, but up there with the best I have tried out in four years of vaping, period.
Pros
- Feature packed device
- Easy to use
- Bargain for the money
- Great build quality
- Interesting slide out magnetic battery door feature
- Great looker (for me at least!)
- Comprehensive temperature control support
- Small form factor
Cons
- Magnetic battery door has a snug fit which can rip battery wraps
- Battery life is quite limited at increased power
Totally agree with all you have said.
They are great mods, I’ve bought 3 now and they are great daily drivers for my Spirals / Cleito and Nautilus X.
I liken them to the Joyetech E-Vic mini in a smaller, higher quality package.
I would recommend people seek out the Aluminium version as it’s much lighter than the standard versions.
