Aspire Nautilus Nano Tank

Nineteen and a half millimetres wide. That makes the Nautilus Nano one of the slimmest MTL Tanks still available from a major brand. It holds 2ml, uses Aspire's Nautilus BVC coils, and ships with a 1.0ohm and a 1.8ohm head in the box.

Bottom adjustable airflow lets you tighten the draw from a restricted MTL right down to something that feels genuinely close to a cigarette. 510 threaded, top fill, stainless steel and glass body. Compact enough to sit on a pen-style battery without looking oversized. Spare glass and O-rings included.

Why vapers choose this:

• Under 20mm diameter means it sits flush on slim pen-style batteries and small mods where wider tanks would overhang or look awkward

• Nautilus BVC coils are one of the most widely available coil types in UK vaping, so finding replacements is never a problem regardless of where you shop

• Bottom adjustable airflow gives genuine range from a loose MTL to a properly tight cigarette-style draw, which not every small tank manages

• Two coils in the box at different resistances let you find your preference before committing to a full pack of replacements

• Spare glass and O-rings included is generous for a tank at this price point and saves a separate order if you crack the glass

Aspire Nautilus Nano Tank Features

Genuinely Small

At 19.56mm across, this is a tank you can carry without it sticking out. It fits in a shirt pocket with a pen mod attached. It sits on a 22mm mod with room to spare on each side. For vapers who want something compact that does not compromise on MTL draw quality, size alone is a reason to pick the Nano over the larger Nautilus models.

Nautilus BVC Coils Are Everywhere

The Nautilus coil family has been around for years, and that longevity is a practical advantage. You will find replacement BVC coils in almost every vape shop in the country, and they are widely stocked online. No worrying about niche coil platforms going out of stock. The 1.0ohm and 1.8ohm that come in the box are the standard Nautilus coils, which means you have a deep supply chain behind this tank.

Bottom Airflow With Real Adjustment Range

The airflow ring on the base is not just decorative. Turning it gives you a noticeable change in draw resistance. All the way open is a looser MTL that produces a small amount of visible vapour. Tighten it right down, and the draw becomes restrictive enough to feel like pulling on a cigarette. Most people land somewhere in between, but having the full range matters if you are particular about your draw.

Top Fill Without Drama

Unscrew the top cap, fill through the port, screw it back. The fill hole is wide enough for most bottle nozzles and dropper tips. No side ports, no sliding mechanisms, no buttons. Clean and simple. On a tank this size, a complicated filling system would be more trouble than it is worth.

Pairs Well With Thinner Liquids

The BVC coil wicking is sized for 50/50 VG/PG or higher-PG blends. Nic salts at 10-20mg in a 50/50 ratio work particularly well. High VG Juice above 60/40 will struggle to wick at this diameter and wattage. Stick to the thinner end, and the flavour stays clean for the full life of each coil.

How to Set Up the Aspire Nautilus Nano Tank

1. Unscrew the base of the tank and thread one of the included Nautilus BVC coils in clockwise. Finger-tight.

2. Drop two to three drops of e-liquid onto the cotton through the side ports to pre-saturate the wick.

3. Screw the base back on and attach the tank to your mod or pen battery via the 510 thread.

4. Unscrew the top cap and fill with 50/50 or higher-PG liquid up to the fill line.

5. Replace the cap and let the tank stand upright for around four to five minutes before you take the first pull.

6. Adjust the bottom airflow ring to your preferred tightness and start vaping at low wattage.

The Compact MTL Tank for Aspire's Nautilus Coil Family

The Nautilus Nano uses Aspire's Nautilus BVC coil platform. That is the same coil family used across the Nautilus, Nautilus 2, and Nautilus Mini. If you own any of those tanks, you already have coils that work in the Nano.

What does not fit: Nautilus X coils (different platform entirely), Nautilus GT coils, and any of Aspire's pod or mesh coil systems. Stick to the standard Nautilus BVC heads, and you are set. The 1.0ohm and 1.8ohm are the standard options, but other BVC resistances exist in the Aspire Range.

About Aspire

The Nautilus was one of the first MTL tanks that vapers in the UK genuinely trusted. When it launched, most tanks were either clearomiser tubes with weak flavour or oversized sub-ohm setups that had no interest in tight draws.

The Nautilus filled that gap, and the BVC coil inside it became the standard that other MTL coils were measured against for years. The Nano is the smallest version of that original design. Same coil, same airflow philosophy, just built into a body that barely adds any width to a pen battery.

Stock Up and Save

Two coils and a spare glass in the box. For a tank this affordable, that is a strong start. Adding a pack of Nautilus BVC coils to your basket means you are covered for several weeks before you need to reorder.

Every order from Pirate Vapes ships the same day before 4 pm, carefully packed. All products are TPD compliant, with an age-verified checkout, over-18s only. Free Pirate Post on orders over £25.

Conclusion

The Nautilus Nano is a compact, well-priced MTL tank that runs on one of the most widely available coil platforms in UK vaping. Two coils in the box, spare glass included, bottom airflow that actually adjusts. It does not try to do anything fancy.

It just delivers a tight, flavourful MTL draw from a body that barely takes up any space. Browse more Vape Accessories at Pirate Vapes.

FAQs

What coils does this tank use?

Nautilus BVC coils. Same as the full-size Nautilus and the Nautilus 2. The 1.0ohm and 1.8ohm come in the box. Other BVC resistances are available separately.

What e-liquid works best?

50/50 VG/PG or higher-PG blends. Nic salts at 10-20mg pair well. High VG above 60/40 will not wick properly in this tank.

Will it fit on a pen battery?

Yes. At 19.56 mm in diameter, it fits comfortably on most pen-style batteries and slim mods without overhang.

How do I adjust the airflow?

Turn the ring at the base of the tank. Clockwise tightens the draw. Anti-clockwise opens it up.

Does it come with a spare glass?

Yes. One spare glass tube and a set of O-rings are included in the box.

Is this an MTL or DTL tank?

MTL only. The BVC coils and airflow design are built specifically for mouth-to-lung vaping. It is not suited for direct-to-lung use.
