Smok GX350 Preview | The Quad-Cell Beast!

The quad-cell GX350 is a monster of a mod with enough power for your most advanced builds or power-hungry tanks.


Smok GX350 Intro

In this preview we take a look at the upcoming SMOK GX350 kit, which includes the GX350 mod and a TFV8 sub-ohm tank. This preview will focus on the mod – if you are interested in learning more about the included TFV8 Cloud Beast tank, check out our review here.

Pure Chinese Muscle


It is interesting that Smoktech makes an automotive reference on their website to the GX350 kit because if this were an automobile, it would be a new Ford GT, with its sexy design and raw (horse) power.

The GX350 boasts up to 350W of power using four 18650 batteries or optionally up to 220W with just two 18650 batteries installed. All of this class-leading vaping power is housed in a sleek “tridimensional polygon design” reminiscent of the Reuleaux RX200 series of mods, and with its rounded edges looks like it will be a pleasure to hold in your hand. The difference here is the fourth battery and the extra wattage.

Where there’s Smok, there’s “tech”


If you are a Smoktech fan, you may have already noticed they have incorporated some design features from their H-Priv mod into the GX350, such as the “triangular firing key” (you basically squeeze the mod to fire) and the top-mounted adjustment buttons and OLED. The OLED provides all the expected information including wattage setting, resistance, voltage, battery life and more. No word yet on whether it will be customizable.

As mentioned earlier, the shape of the GX350 strongly resembles the Wismec Reuleaux RX200 but in a smaller package, yet peeking under the hood we find a quad-battery-powered engine that provides a blistering 350W compared to the more pedestrian 200W output of the RX200. To be fair, Wismec has recently announced their own version of a quad-battery mod (RX300) that will output 300W but pictures reveal a more boxy, and seemingly less ergonomic form factor. It remains to be seen which is embraced by the consumer and, of course, ultimately you will decide.

Regardless, it appears that the start flag has dropped on the race to vaping horsepower supremacy. Buckle up – ’cause it looks like it’s going to be a wild ride.

Can you charge the GX350 with a USB or do you have to do it externally?


I have tried to charge with the micro USB cord and it doesn’t work. I believe you have to use an external charger.


does anyone actually vape at 300+ watts? wouldn’t it be outrageously hot?


Honestly – I don’t.

But there are some sub ohm tanks like the SMOK TFV8 with replacement coils that have ten elements – so I suppose you may need the wattage to fire those up. I haven’t used one but I suspect they vape pretty warm.


I have the smok tfv12 with the t12 coil in it I get to about 250 and call it a day. It gets pretty warm….BUT doable and still is smooth. However I vape around 130-150 with it as a constant. I wouldn’t go any higher than 250 personally, but that is just me. Plus 250 is just a “here let me show you” thing. Why did I buy the gx350??? Because it was new and I picked it up cheap. I think I paid around 50 bucks. Although I must say not being able to charge it with the usb irritates me. I have the wismec predator 228 on preorder that I can say I am more excited about!!
