Kangertech Protank 4 - Vape 2 News

One of the biggest vaping hardware companies in the world has created their version of velocity build deck tank. Many of us were waiting for this tank for quite some time and here it is! A company has investigated current situation and is giving us something that they believe the best tank should  be: Kangertech Protank 4.

Kangertech Protank 4 – one good tank for anyone

Here it is, Kangertech Protank 4, the latest tank in Protanks series. This time, it’s nowhere close to its predecessors. The difference between Protank 4 and previous Protanks reflects how much vaping has evolved over couple years. But before looking at the specifications and performance of this tank, I would like you to know why I have a lot of sympathies for this tank and Kangertech overall.
When the first Subtank was released I loved it so much but I was a bit sceptical about added choice of  RBA, low resistance coil heads, higher resistance coil heads. Why? As many of us at that time, I thought that RBA has to be RBA and tanks with heating coil heads has to stay as they are. Until I’ve got Toptank and gave Subtank with a simple box mod to my smoker uncle. He was sceptical about vaping as most smokers are, but he gave it a go. He couldn’t be bothered with building coils, he used heating coil heads instead. And it helped him to stop smoking as he had a chance to experience real vaping. After few months naturally, he tried building and he got a chance to do it with only one tank he had! And The Kangertech Protank 4 for is another tank which will give a chance for anyone to experience vaping while using coil heads or building double coil builds. I believe it’s still a lot from one tank.

Kangertech Protank 4 construction

Let’s take a look at how Protank 4 is built and how it will improve vaping experience for some of us.
From the top down:

Drip tip of Kangertech Protank 4 is made of stainless steel and Delrin, with one O-ring. Delrin top of the drip tip will stay cool even at highest temperatures so it will allow  Kangertech Protank 4 Drip Tip - Vape 2 Newspushing your mod to its limits if you will want to. The drip tip has adjustable airflow control to mix vapour with more oxygen, a nice feature for direct to lung vaping if you like the airflow holes extremely wide. There are many vapers who love this type of drip tips as well as some vapers can’t stand it. Still, it’s nice to have it available.

Top-Side fill cap is child protected. For filling the tank, a top cap has to be unscrewed until the top part can be lifted. After lifting the top appears the Kangertech Protank 4 E-liquid fill hole - Vape 2 Newsliquid door. The inner ring has to be twisted as the arrow on the liquid door shows. We couldn’t call the Kangertech Protank 4 a 100% protected from the kids as the base of the tank unscrews without any problems, but this child protection gives at least 50% of a chance that kids won’t be able to reach e-liquid inside of the tank.

Pyrex glass window is built into a whole body of the tank, steel construction protects the glass from cracking. One thing to mention: if the glass will be broken there are no replacement glasses available, this would lead to a purchase of a new tank. Personally, I haven’t cracked a single glass of my tanks, but I know some people does it all the time, so keep it in mind, there are no replacement glass tubes for Protank 4.

Adjustable dual airflow holes with stopper will give a wide choice between very loss and very tight airflows. As allrounder Kangertech Protank 4 has done well here, tightening the airflow is good and setting stays in the place as a movement of airflow ring is not too loose.

The Base of Protank 4 is going to work with all Subtank and Toptank coils, it gives a widest possible selection of coils for any type of vaping. Very nice continuity from Kangertech makes this tank even more attractive. There are few generations of those coils, so it’s not too much to say that anyone can find preferable coil head for this tank.

Kangertech Protank 4 build deck

The latest build deck from Kangertech is called PRO RBA, this is a velocity style build deck for a twin-coils building. PRO RBA is very well designed with comfortable grips for unscrewing. It’s simple and pretty straight forward. I had some suspicions about potential leakage problems but if wicked properly without any direct contact between cotton and airflow holes, this tank doesn’t leak.Kangertech Protank 4 RBA PRO - Vape 2 News
Four holes for e-liquid seems not too big but remember the first RBA for Subtank: no one believed those holes were big enough, but they really worked. Same with Protank 4, e-liquid feed is good.
This build deck is not unbeatable, because of more complex construction there are more parts included, I wouldn’t recommend disassembling the PRO RBA base just to check what’s inside as it might be difficult to make it work after reassembling.
One more thing to mention: the holes to space the cotton for liquid feed are not too big so don’t build wide diameter builds where the amount of cotton has to be huge as the spacing of cotton might become a bit complicated.

Kangertech Protank 4 – Conclusion

Kangertech Protank 4 is a great tank for anyone: starting from beginner and ending up with more experienced vapers.
RBA PRO velocity style build deck will allow the owner of this tank to blow huge clouds. Flavour production is really good even comparing to high-end, more expensive tanks. Unbelievable when looking at small liquid holes but this is Kangertech, they can make it work.
Mouth-to-lung coils are made especially for a tighter draw for a mouth to lung experience and for me they remind smoking. However it’s not too tight, so if you want something as tight as cigarettes I would recommend starting with something simpler.
If you are looking for the tank which will cover different styles of vaping, with a wide variety of coil heads and ability to build twin coil builds for huge clouds- Kangertech Protank 4 is the tank for you!

I am a passionate vaper since the first puff of watermelon disposable in 2014. Since then I've traveled interesting vaping journey up to hundreds of watts, dripping and squanking. As vaping has so many levels and styles, sometimes it can be tricky to find what is best for you. For this reason, every time, when I believe device, tool or e-liquid is going to change and improve the life of vapers or smokers preparing to start vaping, I am sharing my opinion about it with you.


  1. Why is my tank leaking so bad it been leaking out the bottom airflow ???? Should I take it back I have only had it 2 days!! It’s seriously ridiculous how much juice has been wasted from it leaking

    • Sub ohm tanks tend to leak a lot… What VG liquid do you vape? Check if coil head is screwed tight on the base.
