SMOK GX2/4 preview

The new GX2/4 gives you the option of portability or raw vaping power.


SMOK GX2/4 Intro

We’ve seen plenty of dual, triple, and quad-battery regulated mods, and even a convertible RX2/3 from Reuleaux that allows the use of two or three 18650 batteries. What’s left you ask?

Allow me to introduce the new SMOK GX2/4 box mod.

With the GX2/4 you can choose to run the mod with either two or four 18650 batteries. In the dual-cell mode the wattage output is capped at a respectable 220 watts. Still not impressed? Slap on the included expansion cover with two additional 18650 cells to unlock 350 watts of lung-searing vaping power.

Regardless of which mode you use the GX2/4 will accept up to a 25 mm atomizer (without overhand), and looks ergonomically designed with a side-fire key, easily accessible controls, and large 0.96” OLED screen. The screen displays tons of vaping data, including: VW/TC mode, wattage, working temperature, voltage, current, vaping effect, battery life, resistance, and puff counter.

The GX2/4 also supports temperature control using nickel, titanium, and stainless steel heating elements, though it is unclear if the mods features TCR.

With big power comes big responsibility, and SMOK thoughtfully incorporates multiple safeguards into the GX2/4 such as: intelligent atomizer recognition, 12-second cutoff, puff monitoring system, and low battery warning, along with short circuit and overheat protection.

Note that the front-mounted USB port is intended only for upgrading device firmware and does not support charging.

The SMOK GX2/4 is available in gold/black, purple/black, silver/black, black/red, blue/black, red/black, and green/black.

The mod is available separately, or in a kit which includes a 5 mL Big Baby Beast sub-ohm tank. SMOK is also offering an EU compliant kit with a 2 mL Big Baby Beast.

Retail price on the kit is $119.95 or $94.95 for just the mod. I found the kit for 100 bucks and the mod for 75 bucks online.

...she’s mighty, mighty…


I like the look of this mod—it bears the unmistakable SMOK design, and looks very much like the Alien and Alien baby—though I hope SMOK has remedied the peeling paint issue found on those. Of course, time will tell.

SMOK also claims the GX2/4 is the smallest 220-watt mod “in the global”, though that is virtually impossible to verify. Another mod that I recently previewed, the 233W Rofvape Z-Box made a similar “small” claim, so I did a quick calculation and the total volume of the GX2/4 was indeed smaller than the Z-Box (104.3CC vs 108CC).

Regardless, the GX2/4 is pretty svelte for a 220 watts, and might be a perfect all-day device for the average vaper in the dual-cell configuration. If you want to get nuts and fog up the family room, the larger quad-cell configuration may be better suited to sitting in your recliner and binge-watching the Walking Dead on Hulu.

As a bonus, you can also use the GX2/4 to inflict serious head trauma in the four-cell “brian-bashing-brick-mode” to any walkers that happen to breach your front door but, please, let us know how the paint holds up.

    I like the idea of these “convertible” type mods (gx2/4 & rx2/3). The only thing is that it seems like you would need a set of 4 married batteries and a set of 2 married batteries if you were planning on using both configurations with this mod.

    • Gary Joseph

      You know, I never really thought about it, but you are correct. You can’t just add and remove the two additional cells. Battery safety protocols dictate that you would need a set of two and another set of four married batteries with the GX2/4.

      The batteries alone cost as much as the mod.

      • Greg Gerhardt

        And you can’t charge in the mod so you might need two sets of 4 and two sets of 2. If this device included quick/equal charge capability I might consider it but nah. Looking at that Vaporesso Revenger now.

    So this is basically what all of us who bought the gx350 thought we were getting up until we received the actual package?
