It is a product such as the Cubis Tank that truly demonstrates how innovative and pioneering of a company that Joyetech is. Keeping their eyes and ears open to the wants and needs of vapers worldwide, they consistently release more advanced devices that genuinely improve the overall vaping experience. The Joyetech Cubis Tank represents the culmination of years of research and development, in an effort to provide the vaping community with hardware that is as close to perfection as possible.

Aesthetically, the Joyetech Cubis Sub-Ohm Tank looks like an elegant sculpture rather than a high-performance clearomizer. Its clean lines are accentuated by the meticulously crafted mouthpiece and internal hardware. The Cubis Tank is furnished with over-sized windows that clearly and conveniently display the remaining amount of e-juices. The glass windows are sunken, which not only enhances its overall appearance, but also protects it with the protruding stainless steel casing. Available in both black and stainless, the Joyetech Cubis Sub-Ohm Tank is a genuinely beautiful piece of hardware.

The body of the Joyetech Cubis Tank is constructed with high-grade 304 stainless steel. This particular class of metal consists of stainless steel, nickel, and chromium in precise consistencies. The mixture provides for strength, durability, resilience, and superior resistance to rust and corrosion. It is due to these traits that Joyetech elected to use this particular grade of stainless steel alloy.

The tank portion of the Joyetech Cubis is fabricated with top-of-the-line Pyrex glass. Although ostensibly a minor detail, the use of glass over plastic substantially enhances the quality of the vapor produced. All e-liquids contain some level of acidity—some more than others. This acidic consistency slowly erodes the interior of the plastic tank, which is not only unsightly, but also alters the flavor of the e-liquid. Glass tanks, on the other hand, are entirely resistant to deterioration from the acid, and therefore provides for a substantially cleaner, truer, and purer flavor.

Joyetech designed the Cubis Sub-Ohm Tank so that it can be completely disassembled. This is an extremely beneficial feature, as it provides you with full access to all of the small crevices of the tank’s various parts. This, then, affords you the ability to clean and maintain your Cubis Tank without the hassle of using small objects, such as Q-Tips, in order to regularly clean the device.

The Cubis Sub-Ohm Tank is equipped with Joyetech’s remarkable airflow control valve. This spectacular component allows you to precisely adjust the amount of air that is drawn into the tank when taking a hit. This is extremely beneficial, as it allows you to determine how tight or airy your drags are. It is also very useful in helping to eliminate flooding and gurgling often experienced with e-juices of varying VG consistencies.

However, unlike the vast majority of airflow control valves that are located at the base of the tank, Joyetech brilliantly positioned the Cubis Tank’s airflow valve at the top of the device. By doing so, Joyetech resolved an extremely common problem often experienced with tanks that have the valve situated at the bottom—leakage. As much attention that has been placed on seals to prevent this problem, leaking through the holes of the airflow valve is something that most experienced vapers have endured at one point. Placing the valve at the top of the tank completely eliminates this issue altogether. By locating the airflow control valve at the top of the Cubis tank, Joyetech also made its exterior much sleeker and more seamless. This detail drastically enhances the overall appearance of the device as a whole.

Inasmuch as the Joyetech Cubis Sub-Ohm Tank boasts an array of incredible features, what truly sets this clearomizer apart from the others is Joyetech’s proprietary cup-style e-juice reservoir. Unlike other tanks on the market that consist of a stationary chimney, which rests at the bottom of the tank, Joyetech designed the Cubis so that the ejuice is contained within a “cup.” The atomizer coil is then dipped into it from above—an absolutely incredible design. This further helps eliminate leaking from the bottom of the tank.

Tied to the cutting-edge nature of the Joyetech Cubis Sub-Ohm Tank is its revolutionary top-fill e-juice system. Although many other top-fill designs exist, due to the cup-style formation, you can simply pour your e-liquid in the “cup” without having to use small slots or needing to worry about avoiding the device’s chimney. You no longer need to use a dropper to cascade the e-juice onto the inside of the glass tube. Rather, you can simply dispense it directly from the bottle into the tank.

Regardless of how incredible the body of a tank is, it is useless without good atomizer coils to back it up. The Joyetech Cubis Sub-Ohm Tank is compatible with two state-of-the-art atomizer coils. The Joyetech BF SS316 Atomizer Head is constructed with high-grade 316 Stainless Steel. This magnificent metal can be used in both variable wattage mode as well as temperature mode. In addition, with the upgraded v3.0 firmware, the BF SS316 Atomizer Coils can now work in TCR (Temperature Coefficient of Resistance) Mode as well. This allows you to set your own specific parameters based on the coil you are using and your personal vaping preferences.

The Joyetech Cubis Tank also operates with the phenomenal BF Clapton Coil. This atomizer head is made with high-quality Kanthal resistance wire, which is fabricated in a Clapton formation. Nearly identical to the way in which guitar strings are made, Clapton coils are created by wrapping larger gauge wire around a smaller gauge one. This provides for substantially larger surface area to make contact with the e-juice. It also fashions small pockets to house the e-liquid, thereby ensuring consistent coil saturation. The result is extremely rich and robust flavor that is accompanied by immense vapor production.

In short, the Joyetech Cubis Sub-Ohm Tank is a genuinely impressive clearomizer that offers style, convenience, and performance in one stunning package. Compatible with most advanced personal vaporizers, the Cubis Tank is an absolute must have for any vaper.
