Sense Herakles: A Sub ohm Tank Worthy of the Name?

Herakles according to Greek legend was the Son of Zeus who had to perform twelve labours to appease Hera and the other Gods, but in the case of this product it’s a new Sub Ohm tank for cloud chasers.

Manufactured by Sense Technology Company Ltd. Sense were formed in 2014 and are based in Shenzhen China. Their primary focus is the R&D, sales and services of electronic cigarettes.Sense Herakles review

Before we do though there is a very important note to make regarding Sub Ohm vaping. While they offer a new way to vape they are not for everyone. Please take a look at our beginners guide to sub ohm vaping before you decide to buy!

This tank will not work with EGO/Pen style e cigs and some of the earlier mods such as the MVP2 and Eleaf iStick 20W. The latter two cannot fire sub 1 Ohm coils. Just be sure your device is compatible.

In The Box

Packaged in a functional black coloured cardboard box:

  • 1x Herakles Sub Ohm Tank
  • 1x 0.6 ohm resistance coil pre-fitted in the tank
  • Spare Pyrex glass tube
  • 1x 0.2 ohm resistance coil.

Sadly very basic packaging, it does the job certainly but the lack of a user manual is something companies should be mindful of considering that many new users and vape converts will be attracted to these products. Even a small note would be a step in the right direction.

The 0.2 ohm coil actually has 30-75w written in it, this is definitely a manufacturing error because having tested the coil 30 watts is not sufficient. Assume it was meant to say 50-75w.

A Smart Looking Tank Reminiscent of the Atlantis

Yes the Herakles looks remarkably like the Atlantis. In fact the resemblance goes one step further since the Herakles is quite capable of using the Atlantis coils which is certainly a nice bonus given that if Sense ever decide to stop making their coils you can always buy compatible ones from Aspire.

I find it a very smart looking tank and it looks good on all my devices. The machining and overall construction is high quality. Everything fits together well.

Base of the Herakles sub ohm tank

The pyrex glass is solid, the drip tip fits perfectly and is wobble free.

One additional point about the drip tip is that internally it is delrin and heat resistant surrounded by a stainless steel outer section, this means it will certainly keep the heat from your mouth when vaping at high wattage.

The tank did have the faint aroma of machine oil so I gave it a thorough wash before use.

Just some minor things:

The bottom of the tank that serves as the airflow control also has stacked fins that serve as the heat sinks. My issue with it is that seeing what airflow setting you actually have selected is somewhat problematic at the best of times. Its a bit like looking though a half closed blind or a car engine grille and serves as a mild annoyance to me.

In actual practice its easy to tell what airflow you have selected simply by using it and adjusting accordingly. The airflow ring clicks when rotated to each of its settings. While it is a little unfair to criticise this it does beg the question did nobody consider this when designing it?

Sadly for those who like to prime their coils by taking a hard draw with the airflow fully closed, the airflow settings do not support a completely closed option.

Regardless of these very small issues I cannot deny the fact that this tank looks great and is very well made.

The tank does not come with a user manual however it is very easy to use.

New to these kind of tanks? Then read this first:

Firstly with any of these sub ohm tanks make absolutely sure that you have a device that is capable of firing at the wattage needed. If you have device that can only put out the minimum needed then while the tank will work it simply will not give you the quality of vape that you will likely want.

So if a Sub Ohm Tank needs a minimum of 50 watts but its operating range is 50-75w then an iStick 50w will certainly fire it but you will likely drain the battery much faster with continued use and its only giving you the bear minimum level of performance.

Where did all my juice go?

Sub Ohm tanks by their very nature drain your juice very fast so keep that in mind if you are trying to stick to a budget.

Regarding Mechanical Mods:

If using a Sub Ohm tank with a mechanical mod be certain you are using good quality batteries and that your mod has adequate venting.

Absolutely do not use mechanical mod hybrid adapters with sub ohm tanks, to do has been proven to cause problems and could be very dangerous.

Above all be mindful and stay safe.

Priming Coils:

With sub ohm tank coils you first take the coil and drip juice down the centre of it.

Also apply some juice to the side wicks or wicking holes. It is important to make sure the wick becomes fully saturated. With darker juices this is easy to see and you will notice the wick changing colour. This will help reduce the chance of getting the dreaded burnt taste in your vape.

  • After priming the wick proceed to fill up the tank, then screw in the coil and its attached tank base.
  • Leave the tank for a minimum of 15 minutes to ensure coil saturation.
  • If the tank supports a closed down airflow option you can take a few primer draws to help.
  • Fire the tank at a lower wattage to start with and gradually increase to your desired setting.

The Herakles is so very simple to use:

Yes this tank is straightforward to use so even someone trying one for the first time should have no issues. Mainly due to the fact everything is so well machined and fits together properly.Various parts of the sense herakles sub ohm tank

Filling it is easy but when using some 30ml bottles of juice that had larger nozzles it was a much tighter fit to pour juice in between the main air tube and the glass. Its not an issue for me but it has far less room there than some other sub ohm tanks.

Airflow adjustment is easy albeit slightly troublesome to see what setting its on. The airflow control ring is solid, clicks nicely into place for each setting and never moves of its own accord.

How Does The Herakles Perform?

The Herakles is a great vape, very flavoursome with lots of vapour:

In terms of vaping the Herakles is certainly up there with the Gods of Sub Ohm Tanks. Some embellishment on my part there to fit the theme but it is one of the best so far. I found flavour to be lovely and gives a fantastic smooth vape. I found the sweet spot to be anywhere between 60-75w when using the 0.6ohm coil.

Herakles Tank on Eleaf iStick 30WThe vapour produced is excellent with some very dense clouds and its certainly something of a room fogger.

At all times the wicking has kept up and I never once experienced a dry hit with the Herakles. At 75 watts this becomes quite a very warm vape and to be honest it was a little too warm for me, 65-70 seems to be my preference after a couple of days of using this tank.

The draw is very open but can be closed down somewhat via the airflow control. Personally I love the open draw and its actually just right for me.

So is the Herakles worth it?

It’s certainly more expensive than quite a few other sub ohm tanks.

However, it is very well made so definitely worth it from the point of view that you’re paying for good quality.

The vape as stated is wonderful and I love the warm and smooth quality to it and the vapour production is excellent. It may be too warm for some but it suits me perfectly.

I am left feeling extremely impressed with this tank. Also given that it can use the Atlantis coils it does make the tank somewhat flexible.

It does drain the juice very fast but I wouldn’t say any more than any other sub ohm tank. It could get very expensive to run if constantly using premium quality juice but for those like myself who make their own it won’t be a problem.

As to coil life I have been heavily chain vaping on the Herakles for two days and the coil is still working fine. I estimate coils should last at least a week.

Final Thoughts

A truly excellent sub ohm tank that is well machined with no real drawbacks. This is a good quality product that will give you an extremely satisfying vape.

Lets break things down with the major points.

The Good

  • Well machined
  • Simple to use
  • Spare glass included
  • Great flavour, very smooth and warm
  • Lots of vapour
  • Nice open draw
  • Drip tip stays cool
  • Atlantis Coil compatibility
  • Absolutely no leaking so far

The Not So Good

  • Heat sink fins make the airflow setting difficult to see
  • Less space for filling, particularly when using larger bottles
  • Drains juice quickly
  • More expensive as an initial purchase than some other sub ohm tanks
  • No user manual. Not really a con but could be annoying to a first time user
  • Slight amount of machine oil and had to be washed first
Build Quality
Vapour Volume
I have been vaping for four years now. I was a 20 a day smoker and a friend of mine encouraged me to give vaping a try. He gifted me with a ego/ce4 set up and some juice and to be fair I found it reasonable but not ideal so I was still also smoking. I went to my local B&M and got some good advice regarding what vaping gear would suit me, as well as finding some juice more to my liking. For a couple of months I used a Vamo V5 but I kept seeing these shiny tube mods and I wondered what they were. After some investigation I discovered they were called mechanical mods and I had to buy my own. From that point I was completely off the cigarettes and quite satisfied with my set up. I eventually moved on the rebuildable devices with my first RDA and RTA. I love vaping and I have no plans to ever stop because there are so many new flavours to discover and a vast amount of different devices with newer technologies to try. While I still own a couple of mechanical mods my preference these days is VW box mods and I really do enjoy a vape with temperature control. I also make my own e-juice as time allows.
