The iTaste Kroma-A kit is the latest release from Innokin and for this version they’ve removed the recessed 510 and introduced a new tank – the Crios.

The 4ml sub ohm tank sits on the now all new flush 510 and gone is that ‘dirty’ yellow colour that featured on the original device.

The Innokin Kroma Gets a Facelift and a NEW Sub Ohm Tank

The shape is the same as is the 2000mAH internal battery which still maxes out at 75watts.

The Crios tank ONLY comes with the none compliant TPD/TRPR kit – with those of us in the EU getting the exact same mod and accessories but with the Axiom Mini 2ml tank.

You can read my full review of the Axiom Mini tank HERE.

You can also checkout Mike’s review of the original Kroma and Slipstream kit HERE.

OK so that’s the scene set so how does the Kroma-A and Crios tank kit perform?

And given a ‘crios’ is apparently a multicoloured woven woollen belt worn by Irish blokes from the Aran Islands – is the kit a belter or a bit woolly?

Let’s take a closer look.

The kit was sent to me by Innokin for the purpose of this review and as always my thoughts and opinions are my own.

Key Features Kroma-A Device

The key difference between the Kroma-A and the original is the style of the 510.

Gone is the recess you screwed your tank into replaced by an improved flush fitting – which really is flush – with all of my 24mm tanks fitting nicely on top without the slightest gap!

It’s still maxing out at 75 watts and the Atheon chip includes a full set of temperature control options including Nickel 200 – Titanium and Stainless Steel 316.

It’s powered with a solid 2000mAH internal battery that has a super-fast charge up time and good longevity and like most Innokin devices you can vape whilst it’s charging.

Key Features Crios Tank

It’s a short ‘n stubby little tank that has an easy screw off top fill and holds 4mls of e-liquid.

There’s two Kanthal BVC Clapton 0.65ohm coils included which fire between 35 and 65watts and look to be absolutely packed with cotton.

The tank is topped with a ULTEM 810 drip tip and will take your own 810 – though I did find with a couple I tired I needed O rings to hold them in place – and there’s also an 510 adaptor.

Kroma-A Quick Start Guide

Anyone who’s used an Innokin device will be immediately familiar with the controls.

  • X3 clicks on and off
  • + & – buttons to move up and down
  • + & – together to check puff count – resistance – voltage
  • Hold + & – to flip screen
  • Hold fire button and + to select temp mode
  • Hold fire button and – to adjust wattage in temp control
  • Note – to increase decrease wattage hold fire for a second then scroll in .5 watt increments
  • To fill Crios tank unscrew top cap and fill via ports

Design and Build Quality

As you might expect from Innokin the build quality of the device is excellent – though I have noticed a slightly annoying fire button rattle if shaken a bit.

Given there’s an internal battery there are no ‘moving parts’ as such however it is extremely ergonomic and very comfortable in the hand – the grip really does give this mod a rugged but stylish feel.

kroma-a kit in hand

I received the black and grey version which for me looks so much better than that horrible yellow of the original Kroma – green – blue – red and white versions are also available.

I’ll hold my hands up here and say I was never really drawn to the original Kroma – more the colour combos than anything else [that dirty yellow was horrid!] and of course I was a big Coolfire fanboy – but the new style of 510 and the more muted splash of colour means IMHO the Kroma-A looks great.

As to the tank and at the time of writing – the kit is still on pre-order and comes with stainless steel or the black Crios tank.

It is very similar in looks and style as the Innokin Scion and everything fits together well and comes apart with the minimum of fuss.

So all in all it’s a nice looking little kit that’s well made – looks good and is comfortable in the hand.

Most importantly – how does it vape?

How Does the Innokin Kroma-A and Crios Kit Perform?

OK, the Kroma-A does its job well with the minimum of fuss and handled my temp control test with no issues – yes I finally bought some stainless steel wire!

The menu is as simple as it gets and both regular Innokin users and newbies will find it easy to navigate.

I have used the Kroma-A with a variety of tanks and RDAs and ramp up time was good – not brilliant – but good and at a steady 63.5 watts I was getting approximately 6 to 7 hours use before it needed charging.

Vaping on the Crios tank is very similar to the experience on the Scion tank – but with one major difference.

crios tanks

You will remember the Scion tank was Innokin’s first venture into the high wattage wars and they almost pulled it off – however I felt the lower ohm coil couldn’t really handle the power.

Maxing out at 65 watts means the Crios coils have a lot less work to do and the generous amount of cotton means they are wicking like a dream.

However, you will need to persevere as like similar tanks the ‘break-in’ time can be as much as 3 tank fills!

crios coils

I received a few extra coils so was able to really put this to the test in as much as I gave up on the two that were in the kit thinking they were ‘duds’.

That’s not the case at all – they just need time to break in – which is annoying given the flavor is very muted – but once they are you get an OK vape.

The flavor is shall we say a 7.5 out of 10 at lower wattage but up around the max of 65 watts and whilst not bursting with flavor my current go to e-liquid tasted good – but not brilliant.

Vapor production though was very very good even with the 70 VG 30 PG e-liquid I was using.

As to how long the coils will last?

Once I’d let one break in a bit I’m vaping on the same one and now into my 15th day – can’t say fairer than that!

What I Like

This is a dinky little kit that can chuck some decent vapour and eventually give a reasonable flavor.

I’m glad they’ve dumped that dirty yellowy brown colour scheme and indeed that recessed 510 as now you can pop any tank or atty on you’d like.

It’s very comfortable in the hand and of course the menu is refreshingly clear and simple.

If you loved the original Kroma then you really will enjoy this slight upgrade.

What I Don’t Like

Maybe maxing out at 75watts for an upgrade to a device is a little shall we say ‘safe’ but then Innokin are known for safety first.

It has to be the break in time for the coils I’m not keen on.

As I’ve mentioned there’s a hell of a lot of cotton in them and even literally drenching them before use and beginning on the lower end of the wattage still meant a 3 tank fill before they popped into life.

That’s 12mls of your precious e-liquid going through them before you get a half decent flavor and even half a dozen fills later the flavor is there but almost desperate to come through!

I have pushed them above the recommended wattage but sadly they really couldn’t handle it giving a nasty burn taste within a couple of puffs.

Final Review Verdict

Innokin has made some absolutely fantastic devices and the Kroma-A is one of them.

It does everything you need with the minimum of fuss – though ramp up time can be a little slow with some of the larger coils.

Sadly, for me, the Crios tank is going the same route as the Scion tank and that is on my atty stand and out of rotation more not to my taste than iTaste if I’m honest.

It looks the part and when it’s decided it’s ready to play you get superb vapour but even when fully broken in – as mine is writing this – the taste is muted to say the least.

kroma-a comparison

The Kroma-A is in the same target market as I guess the Smok AL85 and the Wismec Reuleaux Mini – as a mod it most definitely stands with them shoulder to shoulder but for me as a full kit [meaning the tank] it doesn’t.

As to my recommendation?

I wouldn’t put you off buying the kit – the mod is worth the price alone and who knows maybe your Crios coils won’t taste as wooly as mine – and of course you pop anything on the top you like!

I have simpler vape tastes these days - I never leave home without a Caliburn G, a Vaporesso Luxe 40 or Innokin EQ FLTR and a CBD vape pen or bottle of CBD drops in my rucksack...or indeed an Aspire Nautilus Prime X in my pocket... At home I'll be using various mods topped with the GeekVape Zeus X RTA or the Signature Mods Mono SQ topped with the Augvape BTFC RDA... I'm a former journalist and now a writer and sometimes author... I'm ex Army - adore dogs and never happier than hiking over the hills or with a good book on a beach.

innokin-kroma-kit-reviewed-include-crios-sub-ohm-tankThe Kroma-A device is a pleasure to use however the Crios tank lets the side down with a very long break in time and muted flavour - great vapour though!
