A Complete Guide To The SMOK GX350 Mod

If you’re looking for help with your SMOK GX350 Mod or just need guidance on how to operate it, then we highly encourage you to check out this complete and detailed guide to the GX350 Mod.

The GX350 Mod by SMOK has become one of the most talked about mods to hit the vaping market in 2017.  In fact, it joins a list of other incredible devices created by the SMOK brand, one which has taken home the first place award in GuideToVaping’s Best of 2016 event.  The GX350 Mod in particular has gained great popularity rather quickly due to its unique design, its monstrous power, and its incredible ability to hold four 18650 batteries, making it an all-around mod that can deliver in all aspects.

The new SMOK GX350 Mod is obviously an over-the-top device, but unfortunately not everyone that purchases it knows how to use it correctly.  Moreover, you don’t know how many times viewers of this blog have shared with us that they’ve misplaced or thrown away the user manual that comes included with the device… and half of the time these user manuals provided by these Chinese manufacturers aren’t quite up to par when it comes to the English language.  With that said, we want you to become familiar with your new Smok GX350 Kit, we want to list how to operate it, its features, and its specifications so that you know everything about the Smok GX350.  If this guide has helped you in any way, we ask for your help in sharing it with your friends and other vapers throughout the social networks you use. — we truly appreciate your help!

About The SMOK GX350 Mod

The GX350 Mod manufactured by SMOK (Shenzhen IVPS Technology Co., Ltd) is constructed from a superior Zinc Alloy material.  It sports a poly angular frame, unique in design, and an appearance that offers just as much appeal as it does wattage — and it offers a lot of wattage.  Though it isn’t the smallest device released by SMOK, it still offers a comfortable size, standing only 84.5mm tall, 58mm wide, and 40.4mm in depth.  Despite its larger than normal size, users are still very attracted to the Smok GX350 due to its various colorway options, which includes Black & Red, Black & Silver, Black & Gold, Black & Purple, and a very rare Rainbow color that you only see pictures of, but are never able to actually find it being sold.

SMOK GX350 Battery Confiruation

It isn’t just the appearance that makes the GX350 Mod so spectacular though, it’s also because of its ability to hold four 18650 batteries for a longer than normal battery life, along with its ability to hold only two 18650 batteries.  If using the 4-battery configuration, you can reach up to 350 watts, but if you’re using the 2-battery configuration, you’ll still be capable of reaching up to 220 watts.


ATTENTION:  The SMOK CEO has learned that the 2-battery configuration originally advertised has caused a malfunction with the GX350 Chipset.  Therefore, he has started including notes in the latest packaging for the SMOK GX350.  Below is the note you’ll receive:

Dear Valued Customer:  Thanks for your choose of GX350!  To improve the stability of the GX350, we canceled the functional of supporting two 18650 batteries to work.  We are sorry for the inconvenience thereof.  We shall work even harder to create the best products.  Best regards, CEO of SMOK.


SMOK GX350 OLED ScreenAs you would expect, the GX350 Vape Mod also features the latest tech, such as a full temperature control suite.  While in the temp control mode, you’ll be able to use Ni200 Nickel, Titanium, and Stainless Steel coils.  Moreover, you’ll be able to range from 200 to 600 degrees and fire as low as 0.06Ω.  Additional features include a top mounted intuitive OLED display screen, a hinged battery door to hide its battery compartment, a stealth firing button bar, a micro-USB port that’s used for firmware upgrades only, stainless steel 510 threading, a spring-loaded gold-plated 510 pin, and a slew of safety features that’s equipped to protect both you and your device.

  • I tried to update the firmware on mine and the moment I clicked download on the settings my screen went black and now it will not turn on. Even with the batteries fully charged.

    • i did the same i think the GX350 doesn’t have a firmware update yet. you may have loaded G320 firmware on it. im trying to figure out how to undo it or trying to see when the GX350 will have a update.

  • I’ve had a dream my gx350 for about 2 weeks and it’s worked perfectly until now, I have 2 4 sets of batteries and both sets are fully charged but i put them in and it won’t turn on

  • Ok i got the GX350 I want to see if they had a update for it and I believe I may have loaded G320 firmware in is and Im trying to figure out how to undo what i did any ideas/info?

    • This is the most obvious, but I need to ask if you’ve turned the device on with 5 clicks to the fire button? If that isn’t the issue, I would recommend contacting the store you’ve purchased the device from and see what they can do to fix the issue or replace the device.

    • That is because one of the up-down buttons is stuck in the depressed mode. Dirt or eliquid may have entered that button. You need to figure out which side is sticking an flick it repeatedly until the inner button rectifys.

  • Ok so I am now on my second gx350 its been maybe a month since I’ve had this one and about a couple weeks on the first one. I love the mod and am pleased with all the settings and control I have with it. My problem with it and this being my second one with married batteries which I always use 4, is that the screen dims down then just disappears out of no where with my batteries being close to over half way. Is this a common problem with theses mods or am I just getting defective ones.

  • I’m having a problem with my gx350 vape. some how my vape screen is on stealth mode. how do I turn on my screen?

  • you stated in your review (smok also states it the user guide) that to get to the menu all you have to do is click the fire button 3 times with the system in UNLOCK mode. this actually caused me a bit of confusion, and cussing. to get to the menu the system needs to be in LOCK mode. please edit this, since you’re trying to help and all.

  • Hi. I recently purchased a GX350 and it keeps displaying, “check battery”. I have tried everything from sealing the battery positions to using different batteries of the same type. Is this a normal problem or did I do something wrong? I would very much appreciate some help.

    • Make sure your atomizer is making a solid connection on the device. Usually the check battery comes up when you don’t have an atomizer attached to the device or if it isn’t making a solid connection. See if that helps.

  • You can also quickly lock and unlock the GX350 by simultaneously pressing the up and down buttons, much simpler than pressing the fire button 5 times each time

  • just bought a GX350 and after firing for a short period I can hear a faint clicking sound? is this normal?

  • Bought smok gx350 brand new and had few days when i click watt button to change watts it keeps unlock and locking i havnt drop it

  • My smok GX350 said timeout and started turning it’s its self on after one push of the botten! I’m not happy with this mod now! It just did it out of no where it was in the car like i went to Wal-Mart and game back and it said “timeout” then I got the botton and then i let it go and it would stop it was like I was holding the botten down but I wasnt. Well i charged my battery and then it came out then it did it again well now it won’t even come on!… so I’m mad because I spant $220 for it and now it won’t work!

  • So when I fire it, it goes directly to mode:watts, I cannot switch to temp or anything else it goes away i click the menu button 5 times and it just locks and unlocks back and forth, which also means my watts at the same number

  • my four batteries are all fully charged, but where it says how charged they are on the screen, it shows one fully charged and the other is empty. How do i fix it

  • Do you know when smok will be coming out with an update? My gx350 is acting crazy and when it turns on it will just go from dim and bright and won’t turn on

    • I do not. I recommend following their facebook page and check back on their website for updates. I think I read in past comments on this page that you can load the default firmware to fix some issues.

  • This is my second GX350, The first one worked fine for a month until the screen dimmed out completely over the course of a week. Now I’ve had my second one for 3 days and the dimming has begun again. Is there any way to stop this in it’s tracks or possibly reverse the issue?

  • I have brought so many smok devices about 10 different ones and I had issues with 3 of them and I just trashed them because there is no way on getting in contact with Smok support I tried everything and now I have the Smok gs350 with so many issues and I only have it for about 2 months im just going to stop supporting and buying any Smok products they don’t care about us the customers not a good way on doing business

    • With the 5th SMOK device not working for you, you should have considered moving to another brand. I’m not sure why you’re having so many issues with the SMOK products you’re purchasing. I’ve used several SMOK products, in which I haven’t had a single issue with. After purchasing these products, you should reach out to the store you purchased from to get support through them. These stores should be showing you better customer service and support. If not, you shouldn’t continue purchasing from them.

  • I just bought my GX350 a month or so ago. It was working fine up until a few weeks ago. The wattage operates by itself and so does the unlock and lock. If I try to press on the wattage temp. it will go back to 350. I am not sure what else to do.

  • I got mine and it seems to be exactly what I am looking for in a device like this. I hear rumers on this flashware though and this worries me. Will this device have unexpected firmware malfunctions down the road? (Note:the gx-350 I got was after the fix with the two battery mode, if that makes a difference) but so far I’m very happy with it and noted no malfunction. Battery lid is a bit tight for my liking. I want it snug and secure but not so snug I fear damaging the device to undo it lol. Minor complaint. Some said the paint is a bit fragile. I haven’t had this yet. As long as it continues to function as designed I’ll be happy as two pigs in a trough.
