The Vapefly Kriemhild II sub ohm tank review, and this is an upgrade to the original Kriemhild sub ohm tank released over a year ago.

It was co designed with German 103, a cross border charity team that Vapefly co founded with Youtuber Dampf Wolke in 2018.

The Vapefly brand itself was established in China back in 2017 initially focusing in on the advanced vapers’ need for rebuildable atomizers.

Since then it has branched out into other vape categories but many will be familiar with the Brunhilde and Galaxies range of rebuildable tanks.

As a manufacturer, Vapefly has put themselves in the rather unique position of opting to cater for individual countries requirements as opposed to designing on a global scale.

They strive to be market leaders in the e-cigarette industry by developing a more positive, healthy vaping community.

Will this review leave me feeling those vibes? It’s time we found out.

What Can We Expect From The Vapefly Kriemhild II Sub Ohm Tank?

Much has changed since the original Kriemhild sub ohm tank.

It’s now shrunk in height and the diameter has been reduced – by 1mm and the knurling on the tank has been vastly improved.

Vapefly Kriemhild II tank side of packaging

Most significantly, The Vapefly Kriemhild II now boasts a new set of coils. Unfortunately they wont be cross compatible with the original tank, as these are significantly smaller in diameter.

New technology arrives in the form of their FreeCore Duplex mesh.

Instead of mesh being attached by two pins either end, there’s now one included between them. It’s designed to increase ramp up time as well as providing a richer, denser flavour quality.

It sounds like they’ve effectively created two mesh coils from a single strip. How will this affect the actual vape experience? That’s another reason why you’re reading this.

You may also being asking where the name Kriemhild comes into play. There’s an answer for that too.

Vapefly Kriemhild II Sub Ohm Tank – Inside the Box

I really like the packaging for the tank. It’s reminiscent of old, weathered pages from a manuscript. Even the font work represents something rather mysterious and medieval.

Vapefly Kriemhild II tank boxed

It’s a slip cover and the box has thumb cut outs which means no ripping or tearing.

A nice, hassle free access into the box which includes:

  • Vapefly Kriemhild II sub ohm tank (War/Peace/2ml TPD version)
  • Spare 5ml bubble extension tube (War/Peace versions only)
  • Bag of assorted O rings
  • Spare 810 drip tip
  • 510 drip tip adaptor
  • FreeCore Duplex K-1 0.2ohm KA1 mesh coil
  • Freecore K-2 0.3ohm KA1 mesh coil
  • User manual
  • Warranty card

Curiously there’s no break down of the contents on the rear of the box or instruction manual.

Instead Vapefly has placed emphasis on the features to this latest version of their popular sub ohm tank.

Let’s take a closer look at those.

Vapefly Kriemhild II Sub Ohm Tank – Key Features

Of course the mandatory 2ml TPD version is available for those that enjoy constantly refilling their sub ohm tanks.

The Vapefly Kriemhild II also comes as a standard non EU version (reviewed here) featuring 4ml capacity out of the box and with the option of increasing to 5ml with the included glass extension tube.

The battle between war and peace rages strong as an overall theme with this tank because alternate versions have been released.

The “W” version includes a metal sleeve covering around half the viewing window (almost to signify a battle mask) while the “P” versions glass window remains fully intact.

An Heroic Sub Ohm Tank..?

In mythology, Kriemhild is the name given to the beautiful heroine seeking revenge for the death of hubby Siegfried in the German saga Nibelungenlied.

The word itself refers heavily to masks worn in battle.

That’s one question answered. I guess now we know!

Aside from the design differences Vapefly are laying claim to the creation of the worlds first Duplex mesh coil also known as mesh 2.0.

It’s designed to be much more efficient, provide improved flavour and increased vapour production. The lifespan is also said to be considerably longer than previous coils.

As with the original tank there’s an RBA section in the works so you may want to keep an eye out for that too.

The tank is available in stainless steel, black, gunmetal, gold and blue.

At the time of writing, Vapefly islooking to expand on the colours and are openly asking the vaping public for suggestions.

Vapefly Kriemhild II Sub Ohm Tank – Design and Build Quality

The Base Section

The tank carries a significant amount of weight but looks to be very solidly built. Being 25mm in diameter it’s likely to fit on most mods.

Starting at the base, the adjustable airflow slots move with just the right amount of resistance straight out of the box, and this is aided and abetted by some chunky knurling that works a treat.

There’s a protruding gold plated 510 pin for those wishing to use a mech mod..

This is a dual airflow configuration and the cyclops openings measure around 11mm x 2mm which will allow for an airy direct lung vape.

Unscrew the base of the tank by turning clockwise. This will expose gold plated coil contacts alongside what appears to be a large block of peak insulation.

The threading on the base isn’t the quietest in the world and squeaks like a demented mouse but everything seems to come together OK.

..A little VG lubrication goes a long way!

The Chimney Section

I can only assume the image stamped on the outer chimney is that of our beautiful German heroine.

It’s a classy touch and gives the tank added character.

The chimney carries a hefty O ring for the glass tube to sit snugly around providing reassurance against potential leaking.

The threading for the fill port cap is also silky smooth and I had no issues with rodent impressions here!

There is some doming present on the inner chimney but flavour intensity is likely to be improved thanks to the 6mm airflow restriction traveling up through the chimney.

It includes four wide juice flow openings to coincide with the wick ports of the mesh coils.

Simply push the coil up and inside the chimney ensuring a firm fit.

The Top Section

The entire chamber of the fill port is encased in silicone, which is something I’ve never encountered before.

The dual kidney shaped ports measure a massive 13mm in length with width of 3.5mm.

A massive silicone washer is seated into the underside of the top cap providing an additional seal against leakage.

The top cap itself relies on a simple bayonet style quarter turn. Turning it counter clockwise will very swiftly release it for that emergency top up..

Additional knurling on the top cap helps but it isn’t really needed and acts more of aesthetic value than anything else.

The installed 810 Delrin drip tip is very comfortable in use, being held in place by a single rubber O ring.

It can be a bit difficult to remove but once done can of course be replaced with an alternative.

How Does The Vapefly Kriemhild II Sub Ohm Tank Perform?

0.2ohm K1 Duplex Kanthal Mesh Coil (45-60W)

It has a measurement of 17.3mm H x 13.4mm circumference.

The four wicking ports each measure 5.4 x 3.8mm with the inner bore restricting to 5mm.

Let me cut to the chase.

This coil fires instantly the fire button is triggered. So what about the ramp up time? I would have to say splitting the mesh in half has made quite a difference.

With airflow wide open there is a very minimum amount of restriction. A good hard pull will see clouds tumbling out quite a distance.

It’s bound to please the cloud chuckers out there. Although flavour quality is good here, it’s at mid restriction where the party really begins!

Mid Restriction

The vape is moist but not wet and packs a punch on the rear of the throat during extended inhales.

It’s incredibly similar to any decent RTA currently on the market.

The centre dividing pin is visible when looking inside the coil. It’s the Vapefly Freecore Duplex 2.0 mesh technology

Expect a semi restrictive direct lung vape on this setting. Close the airflow by around two thirds for a truly restrictive DL hit.

At this point I should also applaud the choice of wicking material.

It does much to help with this clean, bright tasting vape experience. Just bare in mind it takes around 15-20 minutes to fully break in.

When it’s broken in the coil is capable of delivering all the multi layered fruity tones from the Wick Liquor Boulevard e-liquid I used for the purpose of testing.

There’s no turbulence of note even when taking the longest of inhales but it does tend to be a little noisy regardless of airflow setting.

The e-liquid is an 80VG/20PG ratio and the Duplex coil had no issues keeping up while chain vaping. The only issue I faced was with the Wife walking into a clouded out room!

Despite this being one of the best stock coils I’ve vaped on for a long time there are a few head scratching concerns, I cover these in the review summary.

0.3ohm K2 Kanthal Mesh Coil (40-55W)

The wicking ports aren’t quite as wide as the 0.2ohm duplex mesh coil but the bore measurements are identical.

This accounts for the same airflow restrictions when vaping.

I used Wick Liquor Miyako forest fruits to test the less powerful of the two coils. Again it’s an 80VG/20PG liquid ratio and is a freebase nicotine content.

When vaping at the highest power setting the Aegis Legend chip read the coil at a respectable 4.1V which feels much more in keeping with what the coil can produce.

With airflow wide open I would suggest the coil is slightly less noisy and again shows no signs of turbulence and has impressive vapour production.

What of the flavour? It’s very good given the lack of restriction, being quite moist during the exhale.

It still can’t match mid restriction when checked, however. The creamy, dense nature of the yogurt is able to really punch through a lot more. The fruit content has the same level of detailing as wide airflow but there’s added sweetness left on the tip of the tongue.

The coil starts creating a few whistling noises when placed under tighter restrictions and to be honest not much is gained by doing so.

As with the duplex mesh coil it definitely favours plenty of airflow to deliver the goods.

I had less success with flavour when the coil was at the lowest power setting of 40W. It was much weaker and took on a stale, bland and one dimensional quality even using a restrictive direct lung style.

Again, there’s not enough power to concentrate the flavour.

The best performance without doubt was found when vaping at highest wattage recommendations and with airflow cut in half. That was my preferred vaping style and where the sweet spot lay.


  • Excellent design and build quality
  • No leaking
  • Very comfortable Delrin drip tip
  • Good flavour and cloud production from both coils (under highest wattage)


  • Duplex mesh coil feels under powered producing only a cool vape at best
  • The K2 0.3ohm mesh coil produces a few nasty metallic back notes

Final Review Verdict

Perplexed By Duplex

Despite the new Duplex mesh coil being one I could happily vape on all day there were curiosities with its functionality.

I used the GeekVape Aegis Legend Mod and the starting recommended wattage output just feels too low because three volts severely hampers the coils ability to deliver.

Although powering up to 55W produces a more flavoursome vape it still only equates to 3.35V. As a result it doesn’t reproduce the warmth needed for profiles such as dessert, bakery or custard vapes which is a crying shame in all honesty.

With this new way of heating mesh I was expecting much more warmth, in a nutshell.

So I have to ask myself if the increase in ramp up time is actually that effective in delivering flavour? It’s not if I’m completely blunt.

I even tried vaping around 70W but the coil quickly showed signs of dry hitting.

..Incredibly the vape was still quite cool.

Keeping It Cool

As much as the 0.3ohm single mesh coil was pushing a more respectable voltage output it too failed to deliver anything other than a cool vape. In fact it produced a few nasty metallic back notes when left to sit for short periods.

This had a tendency of ruining the entire vaping experience. The inconsistency left me wondering when that odd taste would appear again.

I’m not going to suggest that I received a dud coil on this occasion either because both flavour and vapour production were more than acceptable for the most part.

To me, everything just points towards under-powered coils.

Overall Thoughts

The design and build quality of the Kriemhild II is flawless. Everything just comes together really well from the threading to the ease of coil placement.

The quarter turn top cap and filling system are a breeze to use, the Delrin drip tip is one of the most comfortable I’ve come across (nice contouring) and the tank never leaked a drop once during the review period.

Because of the cool nature of the vape with both coils I just feel the Vapefly Kriemhild II sub ohm tank is hampered by an inability to replicate the warmth needed for certain flavour categories.

Unfortunately that has to have an impact on the score summary in terms of performance and so does the inconsistent nature of the 0.3ohm mesh coil.

If by chance you go in for menthol, fruit or beverage profiles it’s certainly a viable option if you’re looking for a new sub ohm tank. I just can’t recommend it to those that enjoy a warm/hot vape.

So as things stand I feel the Vapefly Kriemhild II sub ohm tank is very good but going to be of limited appeal.

vapefly-kriemhild-ii-reviewVapefly return with a compact upgrade to their hugely popular Kriemhild sub ohm tank. It's been immaculately designed with improved knurling and a brand new plug and play coil. Although ramp up time is insane, it's a shame the patented duplex mesh coil fails to deliver the power and warmth needed for certain flavour categories.
