Aspire Zelos Review

Aspire Zelos review. The Aspire Zelos 50w Kit is one of the most popular vapes currently on the market. From my first impressions, it’s not difficult to see why this model is the vape of choice for beginner and intermediate vapers alike.

The Aspire Zelos looks to keep things simple. Right from the off, it didn’t bombard me with unnecessary information about how ground-breaking the kit was, nor did it try to attract me with overblown colour schemes or eye-catching hardware.

I found the Aspire’s simplicity to be a very attractive trait. Right from the off, it immediately hooked me in.

What’s In The Kit?

The imagery on the packaging is as basic as it comes. The front design is simply the brand name and model type alongside a minimalistic drawing of the vape itself. While the packaging gives off a very simplistic vibe, the fact this is a 50w vape is enough to tell you you’re in safe hands, regardless of your levels of vaping experience.

Inside Aspire Zelos 50w Box

The kit comes packaged with the Zelos 50w mod and the much-loved Nautilus 2 tank.

The box opens up to reveal the mod and tank on top with the accessories underneath. The whole kit contains:

  • 1 x Zelos 50w mod
  • 1 x Nautilus 2 tank (with 0.7ohm coil already installed)
  • 1 x extra drip tip
  • 1x extra glass tube (the compartment to insert e-liquids into)
  • 1 x micro USB cable
  • 1 x additional 1.8ohm BVC coil
  • 8 x O-rings
  • 1 x user manual
  • 1 x warranty card

The additional drip tip, glass tank and o-rings were a welcoming addition as these are the kinds of spares you will rarely have to hand. When one of these items breaks, it usually always requires a trip to the nearest vape store or an online purchase (which could then take several day to arrive), leaving you without a vape hit for a while. Luckily, the Aspire Zelos recognises this and offers a quick solution.

The kit also comes with an additional coil. The pre-loaded coil is a 0.7 sub ohm DTL coil, however, the spare is a 1.8ohm coil should you wish to immediately swtich to a mouth-to-lung experience.

Before purchasing the Aspire Zelos 50w Kit, you should ask yourself how important it is that you can modify your vaping experience. The Aspire Zelos walks the line between beginner and intermediate vaping, however, it requires a little more in the way of setup than some of its peers.

Therefore, if modification (such as increasing or decreasing the output wattage) isn’t a factor for you, then consider the JAC Vapour Series S22 Kit as an alternative. The JAC S22 has a tonne of similar features to the Zelos, but retains a more barebones approach.

The Pros and Cons of The Aspire Zelos 50W Kit

The first thing you’ll notice is how sleek and well-designed the Aspire Zelos mod is. It comes in a variety of colours, each contrasted by a silver panel at the top of the mod. You might mistake the Zelos’ simplistic build for a lack of creativity, but on closer look, you’ll see that the Zelos is designed for maximum efficiency.

The mod fits comfortably in the hand, with the fire button being perfectly-placed for either your thumb or index finger depending on your preferences. Clicking the fire button 5 times will turn the device on and off, and can also be used to lock it. The + and – signs increase or decrease the wattage and are used to access the menu screen.

The Nautilus 2 tank has been a favourite of vapers for a while now. While it’s not as easy-to-use as some of the more basic alternatives out there, the Nautilus 2 proves itself to be one of the best tanks available – providing it’s taken care of.

When it comes to the Nautilus 2, the topfill option is one of the most refined as I’ve seen in any mod. In most topfill tanks, it can be very easy to overfill and thus damage the central airflow column. However, the Nautilus 2 takes every measure to avoid this being possible. Usually, topfilling requires removing the mouth cap and filling while the coil is already in place, however, the Nautilus 2 takes a different approach.

Removing the tank cover allows you to pour the e-liquid into the glass tube with more than enough flexibility. Usually, topfill tanks can become quite messy given the tiny gap you have to work with, but the Nautilus 2 avoids this entirely. After several refills already, I haven’t had a single spill or even come close to spilling. Peace of mind for those who have had bad experiences of ruining airflow columns in the past.

Opening Aspire Zelos tank

The build quality of the Zelos is as solid as they come. Every component lines up perfectly, leaving no gaps between sections whatsoever. Having used this for 4-5 days now, I haven’t had a single leak or even a drop of juice outside of the tank.

When it comes to the most important aspect of the vape – the performance and flavour quality, the Zelos has proven to be one of the smoothest experiences I’ve ever had. Something which might seem like a minor positive – but I find is very important – is how comfortable the mouth cap feels while vaping. Unlike JAC Vapour or Smok products, the mouth cap is tight and thin, which allows for a much tighter pull regardless of your airflow preference.

Aspire Zelos re-filling capabilities

It if’s vapour production you’re looking for, the clouds produced by the Zelos should be more than enough to keep you satisfied. Even from an 80/20 e-liquid I found my house engulfed in a thick layer of sweet-smelling mist.

When it comes to battery life, I was averaging around 12 hours with a 0.7ohm coil. With a 1.8ohm coil it was around 16 hours. It also took around 2 hours to fully charge. Not the best battery functionality, especially if you forget to charge it overnight.


  • Sleek and comfortable design
  • Easy-to-operate functionality
  • Unrivalled sub-ohm vaping experience
  • Efficient re-filling capabilities
  • More than enough spare parts included


  • Short battery life
  • Long re-charging time
  • Surface can be easily scratched

What Are The Aspire Zelos 50w’s Best Features?

The two things which keep pulling me back to the Zelos are its superb functionality and its efficient design.

The device is perfect to be carried about and won’t weigh you down when it’s in your pocket. It’s perfect for vaping on the move, and there’s very little chance of spillage if it accidentally gets turned upside down. The perfectly-designed Nautilus 2 tank ensures that even if the kit gets knocked around while you’re on the road, there’s no chance of any significant damages occurring.

I consider myself something of an advanced vaper, and have found that the functionality of the Zelos provides everything I need for the best experience possible. I tend to vape around the 20w mark with a sub-ohm coil, and have found myself preferring the Zelos over my usual vape of choice (various Smok Osub models). While the MTL aspect of the Zelos hasn’t blown me away (although this is related to my personal preferences), the DTL is as satisfying an experience as they come.

the feel of Aspire Zelos

Despite having more than enough functionality to please advanced vapers, I found that the default settings which came with the model were perfect for sub-ohm vaping. So, even if you’re not a fan of tinkering with the mod’s specifications, there’s very little you need to do in order to get going.

One nifty little feature which stands out to me is the screen’s auto-rotate feature. Depending which way you hold the mod, the OLED screen will adapt to your position. While it may seem like a minor feature, it’s the little positives like this which make the Zelos stand out from its peers.

However, the most efficient feature of the Aspire Zelos is the topfill feature of the Nautilus 2 tank. Every time I remove the cap, I brace myself for a few spills down the side of the tank or on my fingertips. However, after almost a week, I’ve yet to feel the irritating splash of e-liquid against my skin.

I’ve checked some other review sites to see what the general opinion of the Aspire Zelos 50w Kit is. Aside from a few complaints about spillage (which is likely due to inexperienced vapers over-filling the tank), the majority of users report similar findings to me.

How Does It Compare To Its Peers?

If you’re looking a vape mod which provides an all-round satisfying experience, the Aspire Zelos 50w might be the ideal kit. While it’s probably more useful to those vapers who have a  few years’ experience under the belt, there are a few alternatives out there which are a little more basic.

The most comparable vape to the Zelos is the JAC Vapour Series S22 Kit. It’s branded more as a MTL vape so it’s perfect for anyone just coming off cigarettes. There’s no screen or functionality available – something which is a big plus to people new to the vaping world. Here’s a comparison between the two:

Zelos: Maximum functionality
S22: Minimal functionality
Zelos: Currently priced around £50
S22: Currently priced around £35
Zelos: unrivalled DTL and MTL experience
S22: Great for DTL, but lacks in the MTL department
Zelos: Mediocre battery life and charge time
S22: Long-life battery and short charging time
Zelos: Perfect topfill functionality
S22: Moderate topfill functionality


Overall, the Aspire Zelos 50w has become my vape of choice for both vaping on the move and vaping at home. I personally prefer a heavier vape in the morning to get the nicotine into my system, and then a lighter vape in the evening. The functionality of the Zelos makes it the ideal mod for both.

There’s not much to complain about at all aside from the Aspire Zelos battery life. However, this can be forgiven due to the fact that the Zelos excels in all other areas of functionality. I would advise this model to those who are looking to progress to intermediate levels of vaping.
