Aspire Nautilus 2 Tank Review – Spinfuel VAPEBefore you click the Buy Now banner directly above this review, you need to understand that this beautifully designed, meticulously crafted tank from Aspire is, first and foremost, a Mouth-to-Lung (MTL) tank. If MTL vaping is not your thing, don’t bother picking up the Aspire Nautilus 2 ($29.99 Vapor Authority). Then again, if you enjoy a good MTL experience, in my opinion, the Nautilus 2 is the best you’re going to get. Before I get into what this tank is all about, know that in the end, the Nautilus 2 will receive an A+ grade from this reviewer.

About the Aspire Nautilus 2 Tank

The Aspire Nautilus 2 MTL Tank, while carrying the name of Aspire’s clearomizer (glassomizer) that helped make Aspire a serious player in the vape industry, is nothing like the Nautilus tanks of years past. Other reviewers, and vendor product pages may try to attach words like “legacy”, it would be beyond a stretch to make a connection to past Nautilus tanks because the “tip” of the drip tip resembles the original Nautilus, and the 5 airflow holes are similar to the original, or the 2mL capacity matches the horrible Nautilus X. The Aspire Nautilus 2 is a unique, new tank.

The Nautilus 2 was designed to bring a modern vaping experience that would provide two things; amazing flavor, and ample vapor production for an MTL pull. You’re not going to get huge clouds with this tank, but you will get enough, and it will be permeated with flavor.

Aspire Nautilus 2 Tank Preview – Spinfuel VAPE

Aspire’s Nautilus 2 makes good use of the BVC Coil Technology, providing true flavor fidelity by using Kanthal A1 heating element in both the 1.8Ω and 0.7Ω coil heads that are part of the Nautilus 2 package.

The Nautilus 2 is 22mm in diameter, making it ideal for nearly all modern box and tube mods. The height is 2.06 inches (53mm), and as you can see in the photos, the Nautilus 2 is a dome-shaped tank with a chrome drip tip sticking up out of the top of the dome. The chrome drip tip is removable, and while at first the drip tip has a snug fit, it will loosen the more you remove it. I would leave the drip tip alone to prevent the drip tip from being too loose.

As far as heat resistance goes, the aluminum alloy dome is more like a sleeve fitting over a glass tank, insulating the user from the minor amount of heat that could be generated within the low wattage range needed for an optimal vape. (more on this below)

The dome screws into the base of the tank, and to fill and refill the tank the user unscrews the dome to reveal a glass tank without a top cap. After filling the tank with up to 2mL of ejuice, the user slips the dome back over the glass tank and screws it into the base. During the time I spent using this tank I did not experience any leaking, nor did any eliquid splash outside the glass tank and into the dome. The dome fits snugly against the glass rim, eliminating any chance of a leak.

The base of the tank is, I suspect, stainless steel rather than the aluminum alloy used in the dome. I say this because of the half dozen I have, the red tank and the dark grey tank have darker bases than the dome. I can’t imagine Aspire using two different shades of red or grey, so I must assume that the metal dictates the final shade of the paint used. In any case, the sliding ring on around the base is used to expose or conceal the 5 airflow holes to adjust the draw. The 5 holes are different sizes, however, even with all 5 holes uncovered the draw is tight. As the user closes off the holes the draw becomes tighter and tighter.

Aspire BVC Coils for the Nautilus 2 Tank

The new Nautilus 2 BVC Coil (bottom vertical coil) technology, is designed to yield the maximum flavor fidelity. No matter which coil head the user has installed in the tank, the flavor fidelity is about as accurate as you can get.

The wicking material is organic cotton, but nowhere can I find any further information about the cotton used in these coils. No matter, the flavor is what counts in a flavor tank, and the Nautilus delivers the flavor in spades.

Although the Nautilus 2 Tank is compatible with the older Nautilus coils, I wouldn’t recommend them. The new BVC coils are the 0.7Ω, rated for 18 to 23W (my optimal wattage is 24W), and the 1.8Ω, rated for 10-14W, (optimal vape for me was 16W). These new coils can be used in the older Nautilus tanks should you have one lying around.

Real World Experience

Aspire Nautilus 2 Tank Preview – Spinfuel VAPE

As a Direct Lung (DL) Vaper I gauged the flavor production of the MTL Nautilus 2 with my SMOK Spirals Tank. The closest I could come to comparing the coils was to use the 0.7Ω BVC Aspire coil (18W-23W) against the 0.6Ω SMOK Spirals coil head (18W-35W). Both tanks are marketed as ‘Flavor Tanks’, and in my experience, they are. Using Angel Sauce eliquid, a 50:50 PG/VG blend from The Plume Room,  I would give the Aspire Nautilus 2 a slight edge of the SMOK Spirals Tank. I was surprised, but there it is.

In our Preview of the Nautilus 2 it is said that the Nautilus 2 vapes like the Kanger K Kiss tank, but my experience did not support that. The K Kiss tank produces more vapor with less draw power, and I can use a Direct Lung style with the K Kiss, not so with the Nautilus 2.

The Aspire Nautilus Tank is a superior MTL Flavor Tank. I spent a week using it with the Vaporshark Switchbox and found it a delight with 50:50 and 60:40 PG/VG vape juice. I did not use the Nautilus 2 exclusively because of my affinity for Direct Lung vaping, but I can honestly say that this gorgeous, modern, tank is the best MTL Flavor tank on the market today.

Aspire Nautilus 2 Tank – Spinfuel VAPE

Grade: A+

“The Nautilus 2 by Aspire is not the right tank for everyone. The Nautilus 2 has a limited 2mL juice capacity, and is an MTL tank. For the many tens of thousands of MTL Vapers that enjoy mouth to lung vaping, I couldn’t recommend it higher.”
