Disassembling the Tank

Taking the tank apart is very easy. The threading of all parts are machined nicely and it all comes apart and screws together nice and smooth. You can take apart the top cap, drip tip, chimney, glass tank, and deck. The deck is built into the atomizer base and can’t be removed.

Building The Deck

This tank doesn’t have the ability to use replaceable coil heads. If you buy this tank you will need to build your own coils.

Start by build your coils to your preferences and leave plenty of leg length so that you can trim it down. If you’re looking for a good starting point for your own coils, the tank comes with twisted wire coils, built at 2.5mm inner diameter, and 5 wraps. The coils they send with the tank measure out to 0.8 ohms, so with some quick calculations, I believe it’s two strands of 30 gauge kanthal.

After your coils are built, you need to grab the coil measuring tool included with the tank. All you need to do is place the coil onto the tool and cut the legs off where the meet the outside of the other side of the tool.

With the coil measuring tool that Wotofo includes in the box, building the deck is pretty easy, because it helps you measure the exact length that the legs of the coils should be to fit just right into the deck. With the original Conqueror tank, you had to estimate the right length for the coil legs, which was a huge pain. The legs would never come out the right size, you would have to keep trimming the legs until you got the right length, and if you cut them too short, you would have to build a new coil. But this new tool gives you the right measurements every time. So don’t lose this tool!

But let’s say that you did lose the tool. The leg length that this tool creates is about 12.26mm, so if you cut your legs down to about that size, they should fit into the deck perfectly.

So the next step is putting the coils into the deck. The coil screws are phillips head screws. Unscrew the deck screws but be careful not to unscrew them too far or they will fall out and can be really hard to find.

With the coil holes open, all you need to do is drop the coils into place and tighten them down. You can reposition and straighten the coil after it’s screwed into place.

When installing and positioning the coils, make sure that the coils don’t touch the airflow holes or it will cause a short.


Get your wicks prepared and shorten them to just a little longer than the wicking holes, then tuck the cotton into the wicking channels. You want to make sure that the wicking holes are covered with the wick. If they aren’t fully covered, e-juice will flood the deck, especially if the tank is tipped, and will leak through the airflow holes. You also want to be careful not to stuff the cotton into the wicking channels too tight, otherwise they won’t wick well.

Before screwing the deck into the tank, prime your wicks with e-juice. Soak them in e-juice, then reassemble the tank. With the tank assembled, unscrew the top cap and fill up the tank with e-juice.

Something to note at this point is that the user manual mentions adjusting the e-juice flow control cap. The original Conquerer tank did include adjustable e-juice flow control settings but this tank does not. I believe it was a misprint in the manual.

Filling the Tank

Filling the tank is easy. First you need to close the airflow holes. If they are open, the vacuum pressure will release and e-juice will leak through the holes. I’ve tested this and it doesn’t just pour out, but it will leak out slowly. The deck will also flood, which means you’ll get a lot of spitback and gurgling until you vape through it.

The fill holes are nice and big, so it’s very easy to fill. The one drawback I’ve found with the top cap is that it doesn’t have a grip, which can make it a little slippery. It has some knurling at the top, but it’s so finely machined that it doesn’t work as a grip.

I also had an issue with the top cap being screwed into the chimney too tight. I couldn’t get it off without twisting the chimney off of the deck. So my recommendation would be to be careful about not twisting the top cap on too tight.

Airflow and Drip Tip

With the airflow wide open, you get plenty of airflow. Halfway closed and it’s a little more restricted. Mostly closed and you can get a very restricted draw, but it still vapes very well.

The drip tip has two o-rings, which keeps it snug in the tank. It’s fairly wide so you get decent airflow from it. You can easily remove the included drip tip and use your own if you prefer.


Ok, let’s talk about leaking. Like I mentioned earlier, the way you wick the tank can cause more or less leaking when it’s tipped. I think I’ve wicked it pretty well and it doesn’t leak at all when it’s standing straight up or when the airflow holes are closed. But if the airflow holes are left open and the tank is tipped, it will leak a little through the airflow holes. I also left it sitting overnight on its side and it didn’t leak at all with the airflow holes closed, but with the airflow holes open, it pooled up in the deck and leaked quite a bit after putting it right-side up.

My recommendation would be to experiment with wicking. Using more cotton and stuffing the wicking slots might prevent leaking issues, but you’ll have to experiment with this to make sure you don’t use too much cotton and cause poor wicking problems.

Pros and Cons


  • It will leak if you don’t wick it just perfect (which is very hard to do)
  • You need to build your own coils, which not everyone likes to do
  • Installing coils is a little more difficult than using a deck with posts
  • If you lose the coil measuring tool, building the deck will be a lot more difficult
  • The tank only holds 2.5ml, which means you’ll be refilling it often
  • It’s easy to forget to close the airflow holes when filling the tank, which will leak


  • The flavor is amazing
  • It’s small and portable
  • It’s affordable
  • You can vape at decent wattages, if you build your coils to support it. I prefer 50w with the included coils
  • It only holds 2.5ml – which means you can refill with new flavors more often

Overall, it’s a great tank, especially if you’re looking for flavor. The flavor this tank puts out is outstanding. The biggest drawback is that the tank leaks if you don’t wick it perfectly, which was the same issue with the original Conqueror tank.

So you can get this tank from HeavenGifts.com for $30.30 and it’s available in black or stainless steel.
