Oooh I have got my grubby mittens on a lovely Wismec HiFlask AIO / Pod mod thingy to review.

hiflask colours

First let me tell you a bit about this odd little device.

It is a sort of hybrid between an AIO (All In One) and a Pod Mod. You have a refillable pod (tank) which slots into the battery housing.

There is an adjustable airflow dial and a catch to release the pod.hiflask airflow

The pod contains a removable coil head which is really handy and a lot less waste than disposable pods which when the coil fails are resigned to ending up inside some poor Seals eye somewhere.

The coils are quirky too – they follow a similar design to the Joyetech Dolphin – in that the coil sits in a plastic housing which is inserted into the pod.

In Wismec speak the coil head is a “JVUA System” – which is Juice Vertical and U Airflow. To translate this means the 0.35ohm coil is horizontal in the pod and the liquid enters the side of the coil! The coil head unit fits into the pod like a drawer!hiflask coil

Inside is a 2100mAh battery which can output up to 40W which is pretty decent for a lightweight small device.

There are 4 colours to choose from – Black, Silver, Blue/White and Red.

This item was sent for the purposes of review. As always my views are my own.

Build Quality & Design

I was sent the Wismec HiFlask in the Red version.hiflask red

It is a very plastic-y feeling device however it looks metal if that makes sense. The red parts are actually like a metallic coating – hence I thought it would be made from metal!hiflask bottom view

No rattles or wobbles everything is tight and fits as it should.

On the top of the device is the mouthpiece which just feels perfect – I don’t know why but it really suits the vape from this.hiflask side view

You have an airflow control dial – more about that later and a catch you move to release the pod from the battery.

There is a battery indicator of sorts a dim light behind the fire button which isn’t that easy to see and it is a bit hard to interpret.

This does feel nice in your hand and the fire button lines up perfectly with where you would want to instinctively press.

In The Hand

How Does the Wismec HiFlask Perform?

Basic operation

hiflask components

  • To turn on or off – press the fire button quickly 5 times
  • To vape – press the fire button
  • Adjust the airflow – turn the dial
  • Release the pod – move the catch in the direction of the arrow shown

Battery Indicator LED – the battery indicator LED will illuminate after each fire button press. The duration/pattern of this light indicates the battery capacity remaining…

  • 60-100% battery left = stays lit
  • 30-59% battery left = slowly flashes
  • 10-29% battery left = moderately flashes (whatever that means??)
  • 0-9% battery left = flashes in frequency (again uh?)

The battery indicator LED will also display if there is a fault…

  • Short circuit – fire button not pressed = 5 flashes and device shuts down.
  • Short circuit – fire button pressed = 3 flashes and device resets
  • Fire button pressed for longer than 10 seconds = 10 flashes and fire operation stops
  • Battery voltage lower than 3.3V = 40 flashes and device shuts down until recharged
  • Coil resistance too high (above 3 ohm) = 10 slow flashes when fire button pressed
  • Coil resistance too low (below 0.3ohm) = 3 quick flashes

How To Charge The Battery

  • Install the small end of the supplied USB cable into the battery.hiflask charging
  • Plug the other end of the USB cable into a suitable USB outlet.
  • The LED indicator will show red whilst charging and will extinguish when fully charged.

How to Fill The Pod

Sadly you do have to remove the pod to fill this.

It is pretty much a guess to the e-liquid level when using and refilling. I have the 2ml pod and it seems full of “stuff” I assume to reduce the capacity – which means there is very little to see through it – you know it’s full when the liquid splurts back out of the refilling hole. Not good is it.

  • Remove the pod by moving the catch in the direction of the arrow.hiflask pod removal
  • Remove the rubber plug covering the filling hole.
  • Squeeze e-liquid into the filling hole whilst observing the liquid level.hiflask refilling
  • Replace the rubber plug.
  • Insert the pod into the battery.

How To Change The Pod

  • As shown above move the catch to release the pod.
  • A new pod simply clicks into place.
  • Refill as detailed above and leave to stand for the coil to absorb the liquid.

How to Change The Coil

This is excellent as you can replace just the coil head on its own. Some pod mods if the coil fails the whole pod needs to be discarded which is expensive and wasteful.

This isn’t easy though – the coil is super snug and I had to get a screwdriver to prise the coil drawer out of the mod.

Plus wait for a while after vaping as the whole white area where the coil is contained becomes blisteringly hot!

  • Remove the pod.
  • Remove the mouthpiece.
  • Turn the pod upside down – if you don’t and there is e-liquid inside it will all flow out of the coil compartment.
  • The coil sits in a little drawer – pull this out of the pod.hiflask coil removal
  • Install a new coil.hiflask coil removed
  • Fill up the tank and leave to stand.

Flavour & Cloud Production

I used some of the beautiful IVG E-liquid I was sent to review in the Wismec HiFlask. It is 70%VG and I added nicotine to take it up to 6mg nicotine.

I also tried my usual Sticka Bombz Fruit Salad e-liquid which is 80% VG.

This part of the review gets a bit rambly – I am so sorry – but the first 2 pods/coils were faulty and when I was about to give up the 3rd pod actually worked – so please bear with me….

2ml Pod Version

I filled up with the 70%VG IVG E-liquid and taste wise this is a bit weak and vapour output isn’t great.

This gets very hot – even the plastic pod and mod body get hot.

It is worst when airflow is on almost minimum – which is where I do tend to have it. There isn’t much vapour production so I am holding down the fire button for quite a while to get a decent feeling vape.

With the airflow in maximum I am still having to do 5 second presses to get an inhale but this is better than in minimum.

When you have been vaping and take out the pod to refill the white part which contains the coil is almost finger cookingly hot – red hot and don’t touch the base of the pod where the electrical connectors are as this will burn. I found out the hard way.

This has 0.35ohm coils so higher PG/Nic e-liquid may be too harsh.

So I installed the second coil head and used some 80%VG e-liquid – my normal liquid with 6mg nicotine to see if it performed any better.

There is more vapour this time. The vapour output is better to be honest. But the flavour isn’t. It is also still getting hot.

This has been such a disappointment – I was pretty shocked so had a look around online to see what others think of this device. I watched a couple of reviews on YouTube and they seem to have tons of vapour! Even on wide open max airflow I am getting barely more than a standard pod mod. These reviews do appear to be on the 5.6ml pod version – is the capacity reducing stuff inside the pod affecting the performance?

It seems to be very underpowered and this is making the device get hot too. The reviews I saw were using 70% or higher VG e-liquid. I have tried 70 and 80%.

5.6ml Pod Version

As I was having doubts about whether the issue was due to me having the 2ml pod version – Wismec kindly sent me some replacement pods with coils in which are the original 5.6ml versions.

Already just visually the 5.6ml pods look better. The 2ml pods are full of white stuffing – either plastic or silicon to reduce the pod capacity. This makes viewing the e-liquid level pretty difficult.

I was thinking all the “stuffing” is possibly affecting the performance and could also contribute to the pods getting hot in use.

So I have fully charged the battery and used my 80% VG e-liquid.

This time around the performance is actually slightly better.

The vapour has just actually made me cough as I was getting so little on the other pod it took me by surprise!

I had the airflow set to kind of half way between max and min and getting a lot more vapour than I was.

The taste and heat considering this is a 0.35ohm coil is still not what I would expect. I have had a nicer vape from the Joyetech Cubox AIO and that uses 0.6ohm coils and much more flavour.

Just to add to the woes of the HiFlask – I am now getting dry hits – does this thing get any worse? The only good thing is that it doesn’t leak.

5.6ml Pod – Number 2

Ok I feel bad about giving this such a lousy review so I have popped a new pod and coil in and trying with 70%VG e-liquid just to see if I can find something positive to say.

Oh and it gets even worse filling this with a bigger spout bottle means you get airlocks and you end up covering yourself and your desk with e-liquid too as it fountains back out of the filling cap.

However this time I am pleasantly surprised- phew – just when I was about to totally throw in the towel with the Wismec HiFlask it has redeemed itself.

I can only assume there were 2 faulty pods and it doesn’t like 80% VG e-liquid. The flavour is lots better, no dry hits and for the first time since I picked this little git of a device up – I am enjoying it!

With the wide open airflow there is loads of vapour and this is a nice warm tasty vapour now too! But I will add the device is still getting very hot!

Battery Life

I was going to abandon this bit of the review as pods 1 and 2 were just an epic fail and vaping on this was becoming a very unwelcome chore.

With the 3rd replacement pod things improved massively – to the point where I can now use this long enough to get an idea of battery life!

So with pretty regular vaping I got just over 7 hours of use (2 full 5.6ml pods) on 1 charge of the battery.

The power output didn’t seem to reduce either right down to the 0-9% battery indication where it did drop off a bit.


  • Lightweight and feels good in the hand
  • Doesn’t leak
  • After 3rd replacement pod was installed this did redeem itself and became nice to use.
  • Efficient battery life and liquid use


  • Airflow dial is a bit fiddly
  • Have to remove pod to refill
  • Air lock when refilling
  • Hard to grip the pod to remove
  • LED placement – behind the fire button and is a bit dim
  • Battery indicator system is hard to interpret – relying on how frequently the light flashes after vaping.
  • Difficult to see e-liquid level – I had to keep tilting or removing pod on 2ml version.
  • Hard to remove the coil head for replacement.
  • Inconsistent pod quality.

Final Review Verdict

This review has taken me weeks – due to the hurdles this thing has thrown at me right left and centre. The first 2 pods I used were nothing short of a huge failure.

The second 5.6ml pod performed way better- I enjoyed vaping on this then! I found it was really efficient on e-liquid and the battery life was excellent too.

However some of the negative points still remain such as difficulty in pod and coil removal, difficulty in filling, pod gets hot, airflow dial hard to grip, battery indicator light hard to see etc…

This really seems to be below Wismec’s usual high standard. The inconsistent quality of the pods could make this an expensive device if it takes several pods to find a good one. A lot of people may have given up with this after the pods kept failing and wanted a refund.

The Wismec HiFlask did redeem itself but it took 3 new pods plus 5 coils to get there.

wismec-hiflask-aio-reviewSo as you can see from above - the 2ml and first 5.6ml pods did not perform and this device really hated me. It redeemed itself after the 3rd new pod was installed and performed well then - but still too many negatives to make this worthwhile. Inconsistent pods made me almost throw this in the bin.
