Sub-Ohm Tank Reviews

Sense Herakles

The Sense Herakles, produced by Sense Technology Company Limited promises to offer performance on a level with the best rebuildables out there, handling high wattage with ease whilst still offering outstanding flavour and vapour results, and a unique finned airflow control design to optimise performance. There has been an awful lot of hype about the Sense Herakles online - it offers much on paper, but does it deliver?

Introduction to the Herakles

Sub Ohm tanks are a dime a dozen these days, a new one becoming available almost daily, production lines in China going into overdrive in order to satiate the demands of cloud chasing vapers everywhere. The choice is overwhelming and these days a new release really needs to be offering something special in order to stand out from the rest of the competition and convince the savvy customer base to part with their hard earned cash...

Enter the Sense Herakles. Produced by Sense Technology Company Limited, a relative newcomer to the market having been formed in 2014 and based out of the manufacturing hotbed of Shenzhen, the Sense Herakles promises to offer performance on a level with the best rebuildables out there, handling high wattage with ease whilst still offering outstanding flavour and vapour results, and a unique finned airflow control design to optimise performance. There has been an awful lot of hype about the Sense Herakles online, it offers much on paper, but does it deliver?

By now, you might be thinking ‘great, another week another Sub Ohm tank’ and wondering what possibly could make the Sense Herakles strike down the rest of the competition? Read on to find out...


  • Optimised coil heads for high wattage usage
  • Delrin and stainless steel wide bore drip tip
  • 3ml capacity
  • 22mm diameter
  • 72mm height
  • Stainless Steel construction
  • Pyrex Glass tank section
  • 0.2 and 0.6ohm dual vertical coils available, with Japanese Organic Cotton wicks.
  • Cross compatible with Atlantis coils
  • Copper 510 connection
  • Unique airflow control

What's in the box?

  • 1x Sense Herakles Sub Ohm tank
  • 1x Replacement coil (this seems to vary per vendor, my unit had a replacement 0.6ohm coil, however I have seen the Sense Herakles offered with a replacement 0.2ohm coil)
  • 1x Replacement pyrex glass tank section


Keeping in line with the Greek Mythology theme of which the Herakles name pays homage to, one of the first things you notice is the Greek style font used for Herakles matches the theme, looking closely at the chimney you find a lion logo visible on the chimney itself resembling the Nemean lion, which King Eurystheus commanded Herakles to destroy as his first labour in Greek Mythology.

The tank itself is composed of a stainless steel construction, with a pyrex glass tank section. it’s really solidly built. The finish is nice and shiny and with the Herakles having a 510 connector and a 22mm width it will sit flush and look pretty on the vast majority of mods. The airflow control ring is definitely different to the others out there, the most striking aspect being the heat fins present on the airflow ring.

Drip tip is composed of a heat resistant delrin inner and 510 connector, and a stainless steel outer shell, this helps keep the drip tip cool during high power usage. It’s something I haven’t encountered on a tank before and the design works really well, as I didn’t experience the drip tip getting hot once during use. Of course, if you wish to use your own you can, as the drip tip is removable and compatible with other drip tips.

It’s definitely uniquely designed, that is for sure!

Sense Herakles Capacity

Capacity wise you get 3ml with the Sense Herakles, which is not an awful lot when you consider how much juice the Sense Herakles gets through! Refilling is a simple case of unscrewing the glass section from the base and filling to the side of the chimney, which sounds easy but can be a little difficult for some users, as the base of the chimney is wide and you can only truly fill this to the top by leaving the coil screwed into the chimney so no juice leaks through the holes at the base of the chimney. I wouldn’t worry too much though, as you will get plenty of practice refilling the Herakles considering how thirsty it is, you absolutely will be refilling this often!

It’s one of the thirstiest sub ohm tanks on the market, and the more power you put through this the quicker you will drain your juice. I have had no issue draining two tanks in an hour when running the Sense Herakles at 70w!

Herakles Airflow

As mentioned in the styling section, the airflow control ring sports heat fins, which help to disperse and draw heat away from the coil itself, in order to keep the Sense Herakles tank cool during high wattage use. That works really well in practice, as even taking the tank above 80w didn’t trouble the Sense Herakles, it never felt too hot for me.  There are four airflow settings at your disposal - essentially underneath the airflow control are the drilled airflow holes, and sliding the airflow control ring around will leave any two of these open at any one time. The airflow control ring slides around with ease, and clicks into place on your desired setting.

To sum up the airflow it ranges from wide (at the tightest setting) to ridiculously huge, and whatever setting you have the airflow on you are going to get some big vapour volume. The airflow control ring is a joy to use, very user friendly and tactile.

Sense Herakles Coils and Performance

There does seem to be a few discrepancies about the coils that are actually provided with the Sense Herakles. One thing is consistent and that is the installed coil provided with the Sense Herakles is 0.6ohm. My Sense Herakles arrived with a replacement 0.6ohm coil, and no 0.2ohm coil, however I have seen the Sense Herakles offered online with a replacement 0.6ohm coil through some vendors, and some vendors offer it with a replacement 0.2ohm coil. I did purchase a pack of the 0.2ohm coils as well, partly because I was so impressed with the performance of the 0.6ohm coils I wanted to see if there was a discernable difference between the two, however the only difference I found that the 0.2ohm coil could be run at slightly higher wattage than the 0.6ohm coil. I actually prefer the performance of the 0.6ohm coil as I think the flavour is slightly better, especially with more complex juices.

The coils themselves, whether 0.2 or 0.6 ohm, are both dual vertical coils wicked with Japanese cotton. As with most, they do need priming, so before using the Sense Herakles you want to make sure that you have primed the coil with juice, by putting a few drops onto the coil itself, filling the tank and allowing it to stand for 10 minutes, then start off low on the wattage and work your way up until you find your desired sweet spot. There are 5 generous juice holes on the coils themselves, and combined with the 6 wicking holes on the chimney itself you can wick even the highest VG juices with ease.

Performance wise I found that the the 0.6ohm coils can indeed be run up to 100w, which I find incredible. I highly recommend running the 0.6ohm coils at a minimum of 40w, and as high as 85w if your mod can support it, as this is where I got the best results for flavour and clouds. Wattage less than 40W gives too weak a vape for me, on both aspects, at more than 85w the vape becomes very hot and flavour seems to drop off. I took the 0.2ohm coil from 45w up to 105w and in my opinion it yielded the same results as the 0.6ohm coil, but I managed to get an extra 5w of performance from the 0.2ohm coil before the vape got too hot and flavour dropped off. The flavour produced by the Herakles tank is incredible, as is the vapour production. My preferred setting is 50-55w, but this varies depending on the juice I am using, but at this range the flavour is outstanding, vapour volume is huge and the vape is nice and warm, just how I like it.

Intriguingly, the Sense Herakles is also compatible with Atlantis coils. Having a couple of these to hand, namely the 0.3ohm Atlantis coil and the Vaporshark Ni200 Atlantis temperature coils, I can confirm that these do indeed work with the Sense Herakles, and they work extremely well too. Running the Sense Herakles in temperature control gives an amazing vape, full of flavour and vapour, I have been running the Vaporshark coils at 45-50J and 240C on the IPV4 and the performance is absolutely outstanding.


The Sense Herakles has been touted as an ‘Atlantis Killer’, and junglist will hate me for saying this, but I believe it beats the Atlantis 2 hands down! I actually ran the two tanks side by side, with the same juice, and at the same power levels, and the Herakles provided far superior flavour in my opinion, and surprisingly bigger clouds. The Herakles also takes the Atlantis coils, which I believe perform far better in the Sense Herakles then they do in the Atlantis 2, certainly I found this to be the case with the Vaporshark Ni200 temperature coils, which have become my preferred coil to use in the Sense Herakles.

Compared against other Sub Ohm tanks out there, the Sense Herakles is amongst the very best, the price point is spot on, flavour is amongst the best I have tried, and it blows excellent clouds. Combined with the fact that it is designed for high wattage use to get the very best out of it, whilst still retaining a cool-ish vape at high power thanks to the delrin drip tip and unique airflow control, and we have a real winner on our hands.

The Sense Herakles with the IPV 4 in temperature control has become one of my favourite set ups, with the balance of flavour and vapour that I crave, it is the setup I currently take out and about with me more than any other I own!

You can win a Herakles tank in our competition - competiton ends 18th July 2015.

He has been involved in websites since completing a degree in Environmental Science in the late nineties.  At that time there was pretty much no contact with computers but on joining the regular workforce and deciding that the world-wide-web was the future he blagged his first job as a web designer and never looked back. As you would expect from a junglist, Dave likes his beats and is most comfortable when the bass is wobbly.
