SMOK GX2/4 Kit - (GX2/4 Mod w/ Big Baby Tank)

Unparalleled in virtually all forms and fashions, SMOK is one of the most distinguished brands within the vaping industry today. Staunchly dedicated to remaining on the cutting-edge of technology, all of their powerful and trailblazing products are immensely popular. With a genuinely impressive array of award-winning MODs and tanks attributed to them, SMOK’s kits are among the very best on the market. With each new release, SMOK shakes the vaping community to its foundation, considerably enhancing and enriching the vaping experience. As such, it is with great pleasure and enthusiasm to announce the latest in their legendary collection of vaping kits—the SMOK GX2/4 Kit. A powerful marriage between the TFV8 Big Baby Beast Tank, and the innovative GX2/4 MOD, this groundbreaking kit is unsurpassed in all forms and fashions.



The incredible SMOK GX2/4 Kit includes the advanced and exceedingly formidable GX2/4 Box MOD. The sensational device is integrated with an array of features and capabilities, making it unequivocally versatile. With the capacity to control virtually all aspects of your vaping experience, the SMOK GX2/4 MOD is capable of accommodating the needs, desires, and requirements of even the most skilled vapers.

Aesthetically, the SMOK GX2/4 MOD is a visual masterpiece. Its sharp lines, exclusive color combinations, and meticulous craftsmanship radiate refined elegance. Its front-facing OLED screen furthers this chic appeal, while the carefully-situated operation buttons emanate progression. One of the most impressive characteristics of the SMOK GX2/4 MOD is its astonishingly small size, given its tremendous power. At under 3 1/2 inches in height, the expert engineers and designers at SMOK have truly demonstrated their proficiency in their capacity to pack so much might within such a small body. In fact, the GX2/4 is currently the world’s smallest MOD able to provide 220W of raw power—a truly remarkable feat.

In accordance with all of SMOK’s popular Mods, the SMOK GX2/4 MOD is constructed with premium-quality materials. Both inside and out, SMOK spared absolutely no expense in the fabrication of this MOD. The device’s body and chassis are made with high-grade aluminum-zinc alloy. An engineering material consisting of aluminum, zinc, magnesium, and copper, this alloy is incredibly durable, tough, and corrosion-resistant, while remaining startlingly light in weight. These qualities make aluminum-zinc an ideal material for a performance MOD, such as the SMOK GX2/4.

The SMOK GX2/4 MOD is equipped with a stainless steel 510 connector, which sits flush with the top of the device. The spring-loaded, self-adjusting contact pin ensures a firm and secure connection between the GX2/4 and any tank you wish to use with it, without being required to manually adjust it. Moreover, the 304-grade stainless steel composition of the connector guarantees that it will be capable of withstanding the strains of constant fastening and unfastening of the tank over extended periods of time.

The face of the SMOK GX2/4 MOD features a premium OLED screen, which digitally displays an array of information in a crisp, clean, and concise fashion. The three-tiered screen vibrantly exhibits a host of valuable data, all of which aid in the ease of operating your SMOK GX2/4 MOD. Once activated, you can closely monitor the output wattage, the temperature setting, the remaining battery life of each battery, the output voltage, the resistance of the atomizer coil, the output current, the mode the device is in, the type of wire integrated within the coil, the length of your puff, and any errors that may potentially occur while the GX2/4 is being used. With this vast spectrum of essential information readily available to you at all times, the SMOK GX2/4 MOD is one of the most customizable and user-friendly vaping devices available today.

The SMOK GX2/4 MOD is embedded with an impressive range of advanced features and functions. Each and every capacity has been painstakingly designed to provide for ease-of-use as well as flexibility. One of the central functionalities afforded by the device is its variable wattage capacity. Using the operation buttons located beneath the screen, you can accurately fine-tune the GX2/4 MOD’s output wattage to a precision of 0.1 ohms. In fact, this superior MOD offers power as low as 6W up to a maximum of a mind-blowing 350W. This massive breadth of available power affords you the capacity to pair your SMOK GX2/4 MOD with any resistance atomizer coil you wish. It can accommodate sub-ohm atomizer resistances as low as 0.06 ohms and as high as 3.0 ohms, making it able to satisfy all vaping styles.

Beyond your ability to fine-tune the device’s power, the SMOK GX2/4 MOD is also furnished with temperature control, sensing, and limiting functionality as well. When joined with an atomizer head containing either nickel, stainless steel, or titanium coils, this gem allows you to regulate the temperature of the coil itself. In so doing, you will be permitted to customize the temperature of the produced vapor, allowing for warmer or cooler hits, according to your personal preferences. Moreover, by regulating the atomizer coil’s temperature, you can avoid the potential of dry or burnt hits, which is a common problem with respect to vaping.

SMOK intelligently designed the GX2/4 MOD to house external 18650 batteries (sold separately). The flexibility to remove and replace the device’s batteries is extremely advantageous, as it affords you the ability to purchase new ones once the batteries in use have surpassed their ability to hold a charge. Moreover, the capacity to effortlessly swap out the GX2/4 MOD’s batteries is also handy, as it permits you carry charged spares with you in case the ones being used are depleted. One of the more radical characteristics of the SMOK GX2/4 MOD is its interchangeable battery configuration. The kit comes with two distinct battery door covers, one which accommodates two 18650 batteries, and the other allowing for a total of four. With a dual-battery arrangement, the GX2/4 offers a maximum output wattage of 220W. For those who require more power, the MOD can deliver a staggering 350W, when equipped with all four 18650 batteries. This versatility is wonderful, as it allows you to determine if you would like a smaller MOD or a more powerful one.

The SMOK GX2/4 MOD is furnished with firmware upgradability. Using the included USB cable, you can connect your device to a computer in order to swiftly download the latest updates. This is a wonderful capability, as it not only ensures that your GX2/4 is always kept current with new technologies, but with bug fixes as well.

SMOK certainly did not overlook safety features in the making of the GX2/4 MOD. This trailblazing device is armed with Reverse-Polarity Protection, Short-Circuit Protection, Atomizer-Short Protection, Low-Voltage Protection, 12-Second Cutoff Protection, Over-Heat Protection, and Atomizer-Low Protection. These integrated safeguards are in place to help protect you from potential hazards when using your GX2/4.


SMOK TFV8 Big Baby Beast:

The SMOK GX2/4 Kit comes complete with the world-renowned TFV8 Big Baby Beast Tank. Made with exceptionally durable and high-quality materials, this spectacular tank is designed to deliver the most flavorful, rich, and pleasant vapor possible. With the capacity to accommodate up to 8 atomizer coils, the TFV8 Big Baby manufactures truly astonishing volumes of vapor that can rival the most intricate rebuildable atomizers builds.

The SMOK TFV8 Big Baby Tank is made with premium 304-grade stainless steel metal alloy. This austenite material is perfect for a performance tank, such as the TFV8, as it possesses all of the qualities necessary for optimal operation. An exclusive combination of steel, nickel, chromium, and silicone, 304 steel is extremely solid, resilient, and resistant to rust and corrosion. These characteristics ensure longevity and resilience, allowing you enjoy your tanks for years to come.

The SMOK TFV8 Big Baby Tank is furnished with a massive 5ml e-juice basin made with premium Pyrex (borosilicate) glass. Compared to its plastic counterparts, the glass composition of the tank’s reservoir is a critical distinction, and one that greatly affects the end-user experience. Since plastic tanks will erode due to the acidic composition of e-liquid, the deteriorating plastic will compromise the taste of the produced vapor. Glass, however, is wholly unaffected by the acidity, and will therefore deliver substantially purer, cleaner, and more enjoyable flavor from your e-juices.

The SMOK TFV8 Big Baby Tank is equipped with a state-of-the-art dual-adjustable airflow control valve, which is located at the base. The valve helps further customize your vaping experience by allowing you to enjoy tighter or airier hits, according to your preferences. By rotating the adjustment wheel clockwise or counter-clockwise, you can precisely fine-tune the amount of air drawn into the tank when taking a drag. The airflow valve is also extremely beneficial, as it helps eliminate the possibility of flooding or gurgling as well.

In accordance with all of the TFV line of blockbuster tanks, the SMOK TFV8 Big Baby Tank is engineered with a cutting-edge system for filling the tank with e-liquid. Rather than constantly disconnecting the tank from your MOD and unscrewing the base each time more e-juice is needed, the SMOK TFV8 Big Baby Tank can be rapidly and conveniently refilled directly from the top, while remaining attached to the battery. More impressively, however, is the proprietary and ingenious way in which SMOK designed the tank’s top-fill system. Unlike the vast majority of other top-fill tanks, which require you to remove the top-cap to expose the juice port, the TFV8 Big Baby’s top-cap is fastened on a hinge, allowing it to be swung open and shut, while remaining fastened to the body. This is an absolutely brilliant configuration, and one that makes refills an absolute breeze.

In order to help ensure that the TFV8 Big Baby Tank can always be kept immaculately clean, well-maintained, and operating optimally, SMOK designed it so that each and every individual component can be detached from the others. This affords you free and unrestricted access to all of the smallest nooks and crannies, without needing to utilize any tools or small objects to access.

Despite the masterful way in which the SMOK TFV8 Big Baby Tank has been engineered and designed, its most notable attribute is the collection of groundbreaking atomizer coils that have been made to pair with it. These ultra-high-performance heads are available in a variety of configurations, including a dual-coil, quadruple-coil, and an incredible octuple-coil variation. Irrespective of the specific atomizer head being used, all of them are made with 100% pure Japanese organic cotton wicks, which are completely free of bleach, pesticides, fungicides, colorant, or other impurities found in standard cotton.

The SMOK GX2/4 Kit represents the pinnacle of vaping technology and advancement. Furnished with every available feature, this remarkable setup provides for the very best vaping experience possible. Exceptionally versatile, amazingly powerful, and astonishingly small, the SMOK GX2/4 Kit is the perfect choice for vapers who are only satisfied with the very best.
