A Complete Guide To The SMOK GX350 Mod

West Coast Vape Supply

What’s Included With The GX350 Mod

The GX350 Mod is available in two different configurations, one with the mod itself, and another that comes as a full kit that includes the SMOK TFV8 Cloud Beast Tank.  We’re going to list all items that come in both packages so that you’re aware of what exactly you should expect depending on which GX350 route you’ve bought or plan to buy in the future.

SMOK GX350 Full Kit



SMOK GX350 Starter Kit

  • 1x GX350 Mod
  • 1x TFV8 Cloud Beast Tank
  • 1x V8-T8 Octuple Coil Head
  • 1x V8-Q4 Quadruple Coil Head
  • 1x Replacement Glass Tube
  • 1x Spare Parts / O-Rings
  • 1x Micro-USB Cable
  • 1x Instruction Manual



SMOK GX350 Mod

  • 1x GX350 Mod
  • 1x Micro-USB Cable
  • 1x Instruction Manual



The real difference between the two offerings is that one comes with the TFV8 Cloud Beast Tank and its accessories that are included with it.  However, what you must know is that the GX350 Mod is typically sold as a full starter kit, rather than just the mod itself.  In fact, you’ll have better chances of finding the kit than the mod itself being sold by most popular vendors.  However, we’ve already done the searching for you and have found both options, which are available by visiting the buttons placed below.  We highly recommend going with the starter kit, as it comes with the TFV8, a tank known for its great performance.

Note: The SMOK TFV8 won 1st place in the Best Sub-Ohm Tank category on GuideToVaping’s Best of 2016 event.

  1. Can this charged via the USB port, or will it require a separate battery charger?

  2. just received my GX350. Put 4 brand new fully charged batteries in it and it won’t turn on.

  3. Why does it say that the USB is used for charging and for upgrading on the package why would it not just say upgradeing.

  4. 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.

  5. 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

  6. 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?

  7. Can i get the firmware to reproreprogram my gx350 .

    • The GX350 hasn’t received an update yet.

      • well it has to have had a firmware update…i bought mine when it first came out and 2 months later bought 1 for my wife…mine is running v1.0.9 and hers is running v 1.1.1. but going to there website there is no official release for the device and now mine is having an issue…i can vape on it but it hits really weak. i have tried my tank on hers and the tank hits just fine…its something to do with my mod as i put her tank on my mod and it has the same issue

  8. I didn’t upgrade or anything. My screen just went black. I have no idea how to get it to come back on…..

  9. Mine has a mind of its own it fires it’s self and changes the wattage up and down by its self and all its freaky as hell what should I do???

  10. hi my gx350 say batery check whats the Problem thanks

  11. 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.

  12. 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?

  13. 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.

  14. 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.

  15. 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

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

  17. 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

  18. 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!

  19. 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

  20. 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

  21. 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.

  22. What is the best recommendation for the watt setting?

  23. 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?

  24. Do I need to turn the device off before I take the batteries out to. Barge them?

  25. 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 have problem with my gx350
        Mod say Too Hot and start to countdown 30 seconds,afther 30 seconds try to vaping but it’s same
        What the problem and how to fix??
        Thank you!

        • Undoubtedly your mod is overheating somehow, maybe due to the battery or there’s an issue with the chip inside of the device. I would see about getting the unit replaced by contacting the store you’ve purchased it from or reaching out to the manufacturer.

  26. 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.

  27. 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.

  28. I dropped mine and now it won’t turn on. Nothing seems broken except thAt it won’t turn on now 🙁

  29. By the looks of all the comments it appears as if Smok is doing their beta testing on their customers.
    Seems like this one is a real piece of junk and should be avoided since there are plenty of good inexpensive mods out there without so many problems.

  30. How come everytime i turn on my gx350 it’s saying “check batteries”. I fully charged them with my efest 4 battery charger my tfv12 is attached firmly? idk what it could be.

    • You need high amp low mah batteries I have your same set up exactly and mine runs perfectly on Sony vtc4 batteries 2100 mah and 30 amps if you run low amp batteries they can’t handle the coil it a massive coil that requires a lot of amperage to run…. hope this helps

  31. The device requiring an external charger means it’s a fail. Horribly disappointing because that means this device is not self sufficient. Now I have to buy an external device to charge 4 batteries??? Crazy

  32. Not sure if youre still responding, but I was hoping to know which coil setting is the one for the original tank the mod comes with. Also which wattage/voltage setting I should stick with. Thanks!

  33. Having issues with this mod it keeps ramping up to 350W then locks me out, got it reset now it is at 6W and won’t let me adjust any suggestions?

    • You need to remove the screen cover and the screws holding in the top plate, then clean off the board under the screen with rubbing alcohol and a cotton swab. Dry it completely before reassembly.

  34. Hello, I own a gx350, it came up on the display saying timeout, I clicked the button then it turned off. All batteries are good, as it says smok gx350thdn version when the batteries go in, but when I try to fire it up nothing happens.

    Do you know why?

  35. Is there a update for the gx350 ?

  36. how do i select the type of coil ?

  37. Thanks Blake. This was certainly more helpful than ill written manual.

  38. What if I bought the kit and want to smoke between 180~240W . How much Ohms do I need and what else do I need to adjust?

  39. Just bought a gx 350 and i have 4 18650 batteries but only 2200 milamps will this run my mod

  40. I have 4 18650 batteries they are2200 milliamps will this run my gx 350

  41. My v8-t8 tank works wonders, but when I use it with my GX350 the could is tasting burnt if i pull too long. If I change the ohms will this stop? What is the recommended settings for wattage and Ohms on the cloud beast tank??

  42. How do you fix the thred fitting if lost

  43. Hi my gx350 works for a little bit then comes up with high input then i have to take batts out to reset it

  44. This thing is a fucking mess. The SMOK alien I think I dropped about 17000 times and it still works perfectly. This thing didn’t work out of the box. Are you assholes paid by the company? No mention of the fact that the battery bay is shit, the thing has constant firmware and power problems, and you apparently can’t charge it with the usb.

    • Us “assholes” aren’t paid by SMOK. Do you think the best selling brand would pay someone to promote their products when the rest of the vaping community already does it for them? come on, you’re smarter than that!

  45. I bought a new one. It’s working so well, but the sreen is not working. I dont know how to fix it

  46. My gx 350 will not change. When i got it i put my batteries in it to chage but it will not change

  47. My mod has been acting up lately and I have no idea of how to fix it. My screen won’t turn on even after I put the micro-USB and with fully charged batteries.

  48. I can not turn on the gx350 with 2 batteries

  49. What does the s w mean on the display?

  50. Hi
    I just bought the SMOK GX350 Kit and this is my first Vape ever.
    Can I only use the Watt and vape on just watt? Or must I set Temp and the resistance too vape?
    If I can use only the watt, what watt should I use for the coils that it cames with?

  51. Hello I recently bought the Smok gx350, and I know it takes four 18650 batteries. I have some 18650 batteries for my flashlights and notice they stick out of the vape. Does the 18650’s need to be a 1.2V, 1.6V? I have a 3.7V and a 3.6V and it doesn’t seem to fit.

  52. I too am a victim of a screen that won’t turn in. Brand new, worked one time, charge batteries now screen doesn’t work…

  53. My vape watt is not turning down using the buttons whe in press the button to turn it down it shows me lock icon on the screen

  54. I just buy one i download the update and i cant even open it again
