The Innokin I.O. kit is marketed as being the “mighty mini vape”!

It is a pod mod style device with a tiny form factor and different pod options.

So is this the simple but hard ass little vape that is promised?

Let’s get stuck in and find out!

What Can We Expect From The Innokin I.O. Kit

As mentioned above this is designed to be a small but mighty little kit. In fact Innokin state that the device with pod is the same size as a cigarette!

I did try to scrounge a cigarette off someone to compare it but I couldn’t and as a (9 month!!) non smoker I have no intention of buying a pack.

Innokin I.O. Kit size

Blimey they are like a tenner for 20 ciggies now! In fact on some vendor sites this kit is cheaper than a pack of 20 smokes!

With this being a tiny kit there are obviously some sacrifices in performance and function.

For instance the battery is only an internal 310mAh capacity and is charged via a micro USB charging port.

There are no switches or adjustments for you to contend with as this has an automatic draw activation – basically suck on the pod and it will fire!

The Innokin I.O. kit uses refillable pods which will hold up to 0.8ml of your own e-liquid.

These have a fixed coil – so when the coil has expired you will need to replace the whole pod, you cannot just change the coil.Innokin I.O. Kit pods

The kit includes 2 different pod options – both with the same resistance but different heating element types:

  • Ceramic heating element – 1.4ohm – usually recommended for CBD e-liquids – green fill plug
  • Kanthal (wire) heating element – 1.4ohm KAL – ideal for thinner high nicotine or nic salt e-liquid -black fill plug

Innokin I.O. Kit colours

There are 5 colours to choose from – Stainless Steel, Blue, Black, Rainbow and Gunmetal.

As a result of me having issues with my kit – Innokin have kindly sent replacement devices and pods for me to see if it was just the kit I received which had issues.

So I will be giving this another test run!

Build Quality and Design

This really is small – and very light. But the body is a metal feel material so it doesn’t feel cheap at all.Innokin I.O. Kit size comparison

I received the Rainbow colour version and it is lovely to look at!

The size and weight of this means you can actually hold it in your mouth like a cigarette if that is your vibe!Innokin I.O. Kit front view

On the front of the device is the LED indicator light – which basically only lights up white, and towards the bottom of the front is the I.O. logo.

The rear of the device has the Innokin branding and the required legal logos.Innokin I.O. Kit rear view

On the side of the device is a dimple to locate the pod and below that is a hole which I assume is for airflow – this is the same on both edges.

The base of the device has a black plastic cap which houses the micro USB port, which works fine and no wobbly bits!Innokin I.O. Kit usb port

For some reason there was a sticker on the rear of mine which stated the battery capacity – easily pulled off though.Innokin I.O. Kit review

I am not sure how the pods are held in – this doesn’t feel like a magnet, more of just a tight fit, but there is a small click when the pod is located correctly.Innokin I.O. Kit pod contacts

Inside the pod port are the two spring loaded connectors which look like a pair of boobies!

I have to say this is a cute little thing!

Innokin I.O. Kit – Pod

There are 2 different pods in the kit – one is a Kanthal Wire and the other has a Ceramic heating element.

The colour of the filling plug indicates which is which.Innokin I.O. Kit pods bottom view

The filling plug is pretty secure and held onto the pod when you uncover the fill port for refilling.

Although there are nozzle adaptor thingies in the kit I did find my usual 10ml nic salt bottles had a small enough nozzle to allow me to fill the pods easily.

But that did work for the first fill only. After that I had to use the nozzle adaptors as air locks inside the pod made filling tricky.

It was hard to get the liquid to fill the pod evenly and a lot of tilting and shaking of the pod to try and get both sides to fill.

There is only the one fill port and doesn’t seem to be anywhere for the air to escape when filling so this can be a messy business even with the included nozzle adaptors as it just forces liquid back out of the pod.

The design of the nozzle adaptors means they just push onto the nozzle of a bottle you already have so quite handy really. You may encounter annoyance if you use drip type bottles!IO nozzle adaptor

The pods have a dark frosted finish but you can see the e-liquid level quite well if you hold it up to the light.Innokin I.O. Kit pods side view

I also found when the device had been lying on its side – the first vape when you pick it up gives you a mouthful of e-liquid.

I found if you remove the pod, and inhale on the mouthpiece whilst covering the base of the pod with your thumb to block the airflow does help to clear this.

It is a shame as this device will not stand upright so you have no choice but to lie it down!

However there is a huge design flaw with the Innokin I.O. kit pods which you will see further on in the review…

Innokin I.O. Kit – Quick Start Guide

Before first use, make sure to fill up the pod – if you inhale on the mouthpiece before the pod has been filled you will damage the pod and it will need to be binned!

Basic operation

This is a super simple device to operate. No buttons or controls – you simply inhale on the mouthpiece and the device should fire.

A single LED informs you of the following:

  • Battery capacity = the LED will flash 10 times when the battery power is low
  • During charging = the LED will be on whilst charging and will turn off when fully charged

How To Charge The Innokin I.O. Kit Battery

  • Use the supplied USB cable install the small end into the USB port on the battery.IO charging
  • Install the large end into a suitable USB outlet.
  • The LED will light up during charging and go out when fully charged.

I found this took over an hour to charge from empty using the 0.5A USB ports on my PC.

How To Fill The Innokin I.O. Kit Pod

  • Remove the pod from the battery.
  • Turn the pod upside down and pull out fill port plug.
  • Using a thin nozzle bottle or the included nozzle adaptors add e-liquid into the fill port and observe the liquid level through the pod.IO refilling nozzle adaptor
  • The filling process is pretty difficult at times, the pod will not fill on both sides and often due to air trapped inside the pod the e-liquid will splurt back out of the fill port. I can only suggest flicking, shaking, tapping pod until the liquid flows across both sides and make sure to flick the pod again before installing in case of air bubbles.

How To Remove / Replace The Pod

  • The pod just pulls out and pushes in to the battery.IO pod removed
  • If using a new pod make sure to fill and leave to stand for at least 5 minutes before vaping.

How Does the Innokin I.O. Kit Perform?

This is a low power device with 1.4ohm resistance – so it is not designed for high VG low nicotine strength e-liquid.

I am using my usual CrazySaltzzz Bubblegum e-liquid which is 50/50 VG/PG nicotine salt.

1.4ohm Kanthal Wire Pod – Black Fill Plug

I started with this pod first as I have a slight phobia of Ceramic pods!

Wow this little beast is impressive!

I can taste the bubblegum shining through in my e-liquid and a massive throat hit. In fact I am taking shorter vapes on the Innokin I.O. kit than I am my Voopoo Drag Nano pod with the same e-liquid. So it must be hitting harder.

Airflow wise this is pretty tight but it still auto fires quickly. Within a split second of inhaling the fire kicks in. No sucking a football through a hose pipe to get this to fire.

I like this a lot. My expectations were low I will admit after hating the Yosta version. But this is great! Well done Innokin!

Burnout

So on day two of using the Kanthal pod – I got dry hits – urgh it was horrible.

I had filled the pod so wasn’t concerned it was due to lack of e-liquid. However upon removing the pod and giving it a “flick” a massive air bubble moved up from the area where the coil is.

I tried the pod again and sadly the burning had killed the cotton and gave off a vile bubblegum barbecue flavour.

So it appears the bloody air bubble issue I got when filling also carries down to bubbles preventing the cotton absorbing e-liquid. The air bubble stops liquid getting to the cotton and creating a dry hit which then kills the pod.

I ordered a pack of 3 Kanthal pods – which did arrive but sadly I was sent the flipping ceramic pods in error – however I now have some new pods and will continue and see if this pod lasts longer.

The flavour was lovely before this issue and something needs to change with these pods. There needs to possibly be 2 fill ports to allow the air to escape and fill more evenly.

As for the air bubbles during use I am not sure how this can be fixed other than allowing the air to escape when filling?

Pod Number 2 – Kanthal Pod

My experience with this pod is pretty much the same as with the previous Kanthal pod. Lovely flavour, a total pain in the bum to fill and has burnt out within 2 days.

Just as an illustration – here is the pod I just tried to fill – as you can see only one side has e-liquid, I have left this lying down, standing up, shook it, flicked it etc etc and still the e-liquid is not moving across the pod.

io pod issues

I have also tried blowing and sucking on the bloody thing and still nothing. Sadly this means this pod will get another dry hit when that small amount of liquid on the one side has been vaporised.

Such a shame as the Innokin I.O. kit pods really are the Achilles heel of this kit. Gutted.

1.4ohm Ceramic Pod – Green Fill Plug

Instantly I can tell the flavour output is a lot more muted than the Kanthal pod.

There is flavour and a decent throat hit but this performs at a lot lower standard than the lovely flavour from the Kanthal Pod.

I am quite relieved not to get the usual “ceramic dry hit” which is something which always occurs for me with ceramic coils – with few exceptions.

But I really don’t want to speak too soon…

As I predicted I have spoken too soon and below is the photo of the Ceramic pod and how the e-liquid is not evenly distributed around the pod.IO ceramic pod issues

Yep dry hit time again – I really am fed up now!

Update 20/5/20

I have in front of me new devices and lots of spare Kanthal pods. This means I can now experiment a bit more and try different e-liquids and see if the issue arises again.

Freebase E-liquid

For my first pod I have used a standard (freebase) nicotine e-liquid in 12mg strength, 50/50% VG/PG and a cherry flavour.

As before the performance is excellent, lovely flavour, spot on air flow, quick to fire and excellent throat hit.

The power output matches the pods perfectly.

With my previous pods I was finding they were burning out quick due to air bubbles in the pod preventing the liquid hitting the wicking area. I will keep using this and see if we can get further than 1 day on a pod. Also I will be keeping more of an eye on the pod and flicking out any air bubbles.

I find I have a similar issue on my Voopoo Drag Nano – with the original S1 pods. Air bubbles accumulate and you get a dry hit. You have to flick the pod about a bit to clear them and you are off again.

Innokin I.O. Kit – Battery Life

I really have tried multiple times to time the Innokin I.O. kit battery life whilst vaping, but unfortunately due to the constant pod issues I am having to stop using this device a lot.

For instance I have not been able to actually empty the battery with one pod so far – the pods have failed before the battery! Very annoying.

Pros

  • Pretty looking device
  • Small and light – could easily hold in mouth like a cigarette if that is your thing!
  • Feels really well made
  • Good kit contents
  • Kanthal pod gives impressive throat hit and great flavour for a short time.

Cons

  • Air locks in the pod can cause dry hits and kill the pod.
  • Hard to tell which pod is which – both look the same apart from different colour fill plugs. I had to go on the Innokin website to find out the difference as it was not stated on packaging or instructions.
  • LED only indicates when power is low, there should be a better method than this to warn you in advance.
  • Filling is a pain in the botty – only one fill port means nowhere for air to escape when filling and airlocks, splurting and uneven filling occurs as a result.
  • If pod has been lying on its side (only way to put it down as it won’t stand up) you often get a mouthful of e-liquid on your first vape when picking it up!

Final Review Verdict

I sadly find myself unable to recommend the Innokin I.O. kit.

It is sad as usually Innokin knock out solid starter kits.

The device itself is fine but the big let-down is the pods. I find I actually dread filling it, and because I can only fill half the pod I end up checking the level all the time.

Sorry Innokin the pod design really needs a lot of work.
