Kanger Protank 4

If you have been vaping for a few years then you will probably remember the very popular Kanger Protanks. The Protank 4 is the latest version and as you might expect due to way the vaping market has heavily evolved it bears absolutely no relation to its predecessors. What it offers is a design that caters to mouth to lung and direct lung inhale users. The Protank 4 has a 5ml capacity and you can either use one of the included coil heads or make use of the included RBA section and use the tank as an RTA.

Kanger Protank 4 features

  • 22mm Diameter
  • Height: 65.5mm
  • 5ml Capacity
  • Can be used for both mouth to lung and direct lung inhale vaping
  • Drip tip has adjustable airflow
  • Convenient top and side filling
  • Adjustable airflow
  • Two Post Velocity style deck
  • Child Lock

What’s in the box?

  • 1 x Kanger Protank 4
  • 1 x SSOCC 1.5ohm coil head for mouth to lung use
  • 1 x 0.5ohm ceramic coil head (Comes pre-installed)
  • 1 x RBA head with dual Clapton coil
  • 1 x User Manual

Kanger Protank 4 styling and build quality

The Kanger Protank 4 certainly looks the part with a clean and streamlined design that tends to look good on most mods. The machining of the tank is really good and the parts which are kept to a minimum fit together well but the main section might be something of a deal breaker for some users since it is manufactured entirely as one piece. The glass is built in and cannot be removed which means if you accidentally smash the glass you will have to buy a brand new tank. Now you might suspect that the main section would be harder to clean but that isn’t really the case once you remove the base because there is plenty of room to rinse it out.

What is nice is the top filling system which features a child lock which will be very reassuring for any parents who vape! The included drip tip is made from stainless steel with a Delrin upper section which will minimise the amount of heat that reaches your lips and it also features a small adjustable airflow slot. You can of course happily use one of your own drip tips since all of the ones I tried fitted without issues but you will of course lose out on the drip tip airflow feature. The tank has a 5ml capacity and features two windows so you can clearly see the juice level at all times.

Airflow

The Protank 4 features two "Cyclops" style airflow holes which are fully adjustable. The adjustment ring works well and turns smoothly. Assuming you need even more airflow the drip tip features a small fully adjustalbe airflow slot. All of those features are quite standard on most tanks. The difference with the Kanger Protank 4 comes in with the top portion of the tank.

Ease of use

Filling the tank is easy and you simply turn the upper part of the tank and pull up to reveal the side filling port. The filling system does have a child lock feature which will give parents peace of mind. There is more than enough room for your juice bottle nozzles or droppers so you won't run into problems.

How does it vape?

The quality of vape you get with this tank does vary to quite a degree. I initially tried the pre-installed ceramic coil and while the flavour was pretty good it did need a fair amount of wattage to get the best from it. I found 52W to be about right and this gave a nice amount of warmth and fairly decent vapour production. I did find that the airflow even when fully opened up felt somewhat restrictive and I often had to inhale harder which meant the vaping experience was a little uncomfortable and slightly less enjoyable. 

The 1.5ohm Nichrome coil which is designed for mouth to lung was even more restrictive and that’s coming from someone who actually enjoys this kind of vape. In all honesty I think my Mini Nautilus gives a far better vape then the one I got with this coil and it also feels less restrictive. Flavour with this coil wasn’t exactly great and in all honesty I think its only real advantage was the fact that it really didn’t need more than 18 Watts.

I tried the RBA section with its Velocity “style” deck using dual 26 gauge coils which had a final resistance of 0.5ohm. The build was pretty straightforward to do and the screws seemed to work well. Using this setup I got very nice flavour and good cloud production but as you would expect the juice did tend to drain faster. Even when fully opened up I was still not overly enamoured with the airflow and opening up the drip tip’s airflow slot certainly reduced flavour too much for my liking. In all honesty this view is down to my own personal preference and it is more than likely due to the fact that this tank isn’t really for me but that doesn’t make it a bad product.

I guess the most positive way to look at the Protank 4 is to appreciate the fact that it does cater to a variety of tastes and includes all options for you to try out in the box. For someone new to vaping this might be a good first tank since it allows you a degree of experimentation.

Conclusion

The Kanger Protank 4 is a very well made product with only one major con and that’s the fact that if you drop it and smash the glass you will have to go out and buy a new one.

Ideally I would also like the Protank 4 to have more airflow options since the draw still feels somewhat restrictive even when fully opened up and it doesn’t even feel on par with the Subtank Plus but do keep in mind that is purely due to my own personal preference and someone else might really enjoy it.

Nevertheless given the fact that the Protank 4 offers a nice amount of flexibility and is also reasonably priced it would certainly be well worth checking out if you like the sound of it! In my opinion it might be ideal for someone new to vaping who doesn’t yet know which style of vape experience they prefer.
