Vapmod X-Tank 4.0 Review

We take a look at a massive 10ml sub ohm tank called the Vapmod X-Tank 4.0. This tank looks like some sort of goldfish bowl and holds 10ml of e-juice! Due to its massive juice capacity the X-Tank 4.0 is a rather odd shape. It isn’t your standard cylindrical sub ohm tank that we are used to. The X-Tank is similar in looks to the KS RTA by Holy Land Mods, but instead uses replaceable coils.

The X-Tank comes with 3 different coils: 0.6ohm, 0.2ohm and a 0.2ohm Ni200 head. The coils are very similar to the Aspire Atlantis coils and thus you can use any of the Atlantis 2 or Triton coils in the X-Tank 4.0.

Apparently there is also an RBA version of the X-Tank 4.0 coming soon.
Instructions on how to replace the X-Tank coils and re-fil its monster 10ml tank can be found here.

Note: I think I might have a slightly older version, as I saw a video review in which they had a different air flow. Not sure if mine is the older version, but I think it might well be. Apparently the newer version has fixed some of the issues that the older one had. Check to see before you buy that the vendor is stocking the latest version.

We vaped the 0.6ohm coil on our X-Cube II box mod. Don’t use this tank with the X-Cube 2, as the tank completely covers the screen!

50W – Great clouds already, but lacking flavor wise. A relatively cool vape at 50W.
60W – A slightly warmer vape, but still pretty cool, with flavor starting to come through. Big clouds!
70W – Really great flavor and a nice warm vape, with gorgeous plumes of vapor.​
80W – Getting a bit on the warm side now, but still a nice lush vape with great flavor.
90W – Again a fantastic vape with no dry hits. Massive clouds and lovely flavor.

I’d personally vape the X-Tank between 70-85W on its 0.6ohm coil head.

Tip: One thing I noticed is that when the tank is getting nearer empty, you need to make watch out how you tilt the tank. If you tilt it backwards the juice will go towards the back of the tank and not hit the coil, leading to a dry hit. Make sure you tilt the tank towards the coil, so it is always covered in juice!

​This is the main reason many people will buy the x-tank and is one of the only reasons you would probably buy this tank. The 10ml capacity is fantastic for those who like to sub ohm vape and thus will be getting through a lot of e-juice. Sub ohm tanks drain e-juice very quickly, so the 10ml capacity is great for those vapers who get through lots of e-liquid.

The coils that come with the kit are not Atlantis coils but are very similar in looks. You can use the Atlantis coils with this tank, which I think is a positive, as this gives you plenty of coil options and you will be able to pick up replacements in most vape shops. I also really like that the X-tank kit comes with 3 coils and not just two. You have two Kanthal coils and also an Ni200 one for those who want to vape in temp control mode. Not bad at all for its price!

I was very impressed with the stock coils on the X-Tank 4. The 0.6ohm coil vaped extremely well at its recommended wattages (we used a 75% VG ejuice). The flavor was fantastic and the clouds were massive.

As mentioned above the coils that come with the kit vape very well. I enjoyed the 0.6ohm head the most and the flavor was great. The 0.2ohm head also chucks big clouds, if that is your thing. Overall the coils vape well and are very solid.

​Take this info with a pinch of salt. I have said this in the past about other sub ohm tanks, only to read that others had leaking issues. I did read that some people had leaking issues on their X-Tank 4.0, so this is maybe a bit hit and miss in this department. It could also be that they had the first version and apparently the latest version has now fixed those leaking issues that were present in the first batch.

The X-Tank is massive due to its odd shape and big tank capacity. It won’t fit nicely on a lot of mods, so make sure it will look ok on yours before you buy it. Any larger box mod bar the X-Cube II will look “ok” with it and one or two smaller mods as well.

Vapmod X-Tank 4.0 Review
Mods it looks ok on:

• Cloupor GT
• Innokin Disrupter
• iStick 50W
• Kanger Subox (tiny overlap)
• Sigelei 150W

Mods it won’t look good on:

• X-Cube II (covers screen)
• iStick 30W (won’t sit flush)
• Cool Fire IV

Beauty is in the eye of the beholder. In my eyes this tank looks like a goldfish bowl! It doesn’t look great in my opinion, but those who want this tank, will not be looking at aesthetics, rather will be looking at the practicality and convenience of the 10ml tank.

The tank is plastic and feels a little bit flimsy. You do get a spare which is good, but perhaps a Pyrex tank would have been better and sturdier.

Our air flow controller was terrible. It rattled and was difficult to turn into place and then keep at a certain draw. The air flow on ours features two holes on either side. I have seen videos with people having different air flow hole settings with differing sizes. I think they must have the latest version and mine is still one of the older ones, I am not sure. Let me know what yours is like if you have tried it!

​This isn’t a sub ohm tank for those looking for their first sub ohm tank. The reason I say this is because replacing the coil on the X-Tank 4 is a bit of an ordeal. You need to screw apart the tank and remove the drip tip and tank and then remove another cover for the coil.

You can re-fill the X-Tank 4 from the bottom, but it isn’t very easy to get this cap off and then back on. There is a top cap which comes off and leaves the tiniest gap for filling if you have a pipette/syringe. I couldn’t use a drip bottle through that gap and I have no idea why they didn’t make the gap larger to allow for a top fill. Looking at the latest version it seems the top gap looks different to mine and they recommend filling the tank through it, so perhaps they have fixed it. If anyone has the latest version, please let me know if you can now re-fill through the top.

The X-Tank 4.0 is only for those vapers who really need a 10ml tank and for those who don’t mind the X-Tanks awkward shape and looks.Those people who can look past the size and looks, will enjoy the 10ml tank capacity and a really good vape on a great range of different coils. I felt the overall build quality could be improved upon, but it looks like the latest version has ironed out some of these quality issues.

This isn’t a sub ohm tank for me because of its dimensions, difficulty to change coils and quality issues on the version I tested. However, I can definitely see its appeal and no doubt it will be popular for the heavier sub ohm tank vapers.
