SMOK GX350 Mod


Product Description

The SMOK GX350 TC Box Mod is one of the craziest mods on the market. The GX350 represents the leaps and bounds at which todays vape technology is constantly growing. With a mind-blowing 350-watt output from quad-18650’s (4x 18650 sold separately)! The GX350 mod will smash any competition you may have, however, when paired with SMOK’s TFV12 Cloud Beast King you will quite literally, blow them out of the water!


Despite being a quad-cell veritable powerhouse, this “lil’ guy” is actually quite palm-friendly. Measuring 84.5mm by 58mm by 40.4mm, the GX350 packs all that power into a poly-angular chassis with a gradual contour for both comfort AND cosmetics. 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” or “trigger style firing button” (you essentially 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 laid out beautifully, including a useful and highly accurate individual battery readout. Also, worth mentioning is GX350's ergonomic, ultra-responsive rocker-style adjustment switch. Its chipset features a full range of temp-control options with Ni200, titanium, and stainless steel support; as well as your standard circuit protection/safety features, and a dedicated microUSB port for updating firmware in the future.

Note: The micro-USB port is for firmware upgrades only, you cannot charge batteries with this device. If you do not have an external battery charger you can purchase one here!

VapeWild’s Thoughts and Review

As you will see in our video, the GX350 from SMOK is a good device that only gets better when paired with the TFV12 Cloud Beast King or the TFV8 Cloud Beast. The TFV12 coils will be able to handle the power of the GX350 better than the TFV8 coils, but none the less, both tanks will work perfectly with the GX350. You will need four 18650s to power the GX350 and they are sold separately. We recommend the Samsung 25R or the LG HG2 batteries and also recommend you keep them married or paired as a set of four. We also wanted to point out that having the screen on the top of the mod is awesome because you can see it while you are vaping! Not to mention with the four 18650s the battery life on the GX350 is insane! With that said we did have a few features we did not care for like, the battery sled is tight, this makes it hard to get the batteries in and out the the device, along with the battery door being wobbly and once you put batteries in the GX350 and close the door there could be a gap as you will see in the video.

  1. Great mod

    Posted by Anthony on May 24th 2017

    Love the smok 350. I feel like I'm actually getting the watts I I choose I love how the threads feel nice and tight I also like the puff options it takes all the guesswork out like other products where you had to preheat temperature it's just an all-around great product!

  2. Great but poor screen placement

    Posted by Dean Davis on Apr 26th 2017

    I do love this mod for the power to go with my tfv8 & tfv12. Great battery life with other tanks. Only issue is if you're like me and like the high capacity tanks. Which a lot are 30mm+ the tank hits part of the screen when it's tightened down. If you're using something crazy like the 40mm dumptank. It almost covers half the screen. Small con but other than that great mod

  3. My high power go to

    Posted by Jim D. on Apr 19th 2017

    I actually have one of these I purchased from somewhere else (sorry VW you didn't have them) and it's my high power go to unit for firing the SMOK Cloud Beast and Cloud Beast King. And it hasn't failed me yet. The only reason I took one star off of my rating is because of the battery door. It could be more sturdy, but it hasn't been a real problem for me. And I wish they would have made the display more like the Alien and G320. But I think size would have been affected if they did that.

    As a comparison, the size is pretty much identical to the Eleaf iStick TC200W, which is a 3 battery mod.

    Anyone with an Alien or a G320 will be familiar with how to navigate the screens since they are the same on this mod. The only difference is the main display while vaping. The main display does not show the amperage and it doesn't keep the voltage of your last vape displayed.

    Overall I'm really happy with this mod and would recommend it to anyone.
