The Innokin Jem Pen is the latest vape pen style kit from Innokin, purely a MTL (Mouth to Lung) vape, perfectly aimed at those try to get off cigarettes and venture into the world of vaping.Innokin JEM Pen in hand

Innokin have been in the game from 2011 based out of China, lots of beginner to intermediate level kits in their repertoire.

Their products are easily available in most best vape shops and beginning to appear in corner shops and supermarkets along with other well-known beginner kit brands.

The Innokin Endura T18 2 kit is available in practically every shop in the UK and recent releases such as the waterproof and shockproof Adept Zlide and the Gala Pod system are both top notch performers .

What Can We Expect From the Jem Pen by Innokin?

The Innokin Jem Pen is shorter than a BIC pen and not much wider than a AA battery.

Easily stored in the pocket, bag or just to keep in the hand. Pure MTL with a restrictive airflow (don’t expect to be hot boxing a room), the drip tip (mouthpiece) has the same diameter as a stinky making it perfect for every vape beginner.

Stainless steel construction makes it strong. Steel around the glass tank gives a little bit more protection for the inevitable drop. It comes with both a ceramic and Kanthal coil.

OK.. Let’s get int testing the device to see if it’s a good option for new vapers, or indeed the more experienced.

The Innokin Jem Pen was sent to me for the purposes of this review, I will give you my honest opinion, I have been testing this product for a couple of weeks.

Design and Build Quality

This is a simple and effective design, sleek and compact. With its steel build you can be confident that the Innokin Jem Pen will be able to take a bit of abuse.Innokin Jem Pen battery, tank and mouthpiece

It’s a plain design which is aimed mainly at new vapers, several simple colours are available with one funky looking Cosmos design for those a little more adventurous.innokin jem pen colours

The Jem Pen is what is called an AIO (All In One). Rather than having a separate tank in which you screw the coil, like most vape devices, the coil here is screwed directly into the battery. The tank is then placed over the top.

Overall the build quality is excellent, no rattles whatsoever. The metal sleeve over the tank will help to protect that glass tank, there is not a spare one in the box.

My only issue is with the drip tip, a little knurling (for grip) around the screw cap would make it so much easier to open to fill on a hot sweaty day. Just don’t over tighten it, otherwise you’ll be looking for a couple of elastic bands to try and get some grip.

Fire Button | Airflow

The fire button is well positioned on the Jem Pen. There are 5 lights on the button in a smile shape, colour coded to give you an idea of the power left in the battery.

  • Green = 60 – 100% power
  • Yellow = 20 – 40%
  • Red = 0 – 20%

5 clicks turns the Innokin Jem Pen on, another 5 will turn it off.

The Coils

First off, when you take the Jem Pen out of the box, a coil does not come pre-fitted, make sure and put a coil in before filling the tank!

More on how to do that below.

The coils themselves are small, now you may have got advice before about priming the coils before fitting.

They are that small that if you prime them you will end up flooding the coil and juice will leak from the air hole and you will be spending a bit of time wiping the Jem Pen with a tissue.

How Does The Innokin Jem Pen Perform?

First, let’s take a quick look at how to fill and install/change the coils.

How To Change The Innokin Jem Pen Coil

Inserting the coil couldn’t be simpler:

  • Simply unscrew the tank from the main body of the Jem Pen
  • Screw a coil into the top of the main body.

How to change the Innokin JEM Pen coil
If you are changing the coil and you have juice in the tank, don’t panic, just hold it upside down and unscrew the tank, the juice will not leak out of the drip tip.

How to fill the Innokin Jem Pen

It is very simple:how to fill the innokin jem pen

  • Unscrew the Drip Tip (mouthpiece) from the tank
  • Fill through the two side holes on top of the tank
  • Do not fill juice into the central hole and this goes directly to the coil and will cause flooding and leaking.
  • Screw the drip tip back into place and leave to stand for 5 minutes before vaping to allow the e-liquid to soak through to the coil.

Flavour and Vapour Production

Flavour from both coils is pretty spot on.
innokin jem pen coils

However, I did prefer the 1.6 ohm Kanthal coil over the ceramic 2.0 ohm.

The Kanthal coil handles up to a 70VG/30PG mix of juice with ease, zero dry hits even when chain vaping.

The 2.0 ohm ceramic struggled a bit with the 70VG/30PG mix but worked fine up to a 60VG/40PG mix. A 50PG/50VG juice also works perfectly with both coils and no sign of leaking.

I used a variety of juices with both coils, Pure Mist B&L 50/50, Vampire Vape Pinkman 60/40 and Excision Harambe 70/30. I also thoroughly enjoyed using Daily Vapour (Titanic Vapour) nic salt juice with the 1.6 ohm coil, this was a 50/50 mix.

Flavour from the Jem Pen is great and comparable, if not better, to most of the rebuildable MTL tanks that I use regularly. Bold statement I know!

Coil Life

Two weeks on, I am still regularly using the Jem Pen, it has become my method of getting my Nic Salt vape with the 1.6 ohm Kanthal coils.

This coil is still going strong after a week and a half. Looking at the coil now there could be about a months worth of regular use out of it before I need to change. It still looks clean and like it has only been used for a couple of days.

It’s worth noting that I’m not using overly sweet juice which will have an impact on the colouring and clogging of the coil.

Airflow | Draw

The draw of the Innokin Jem Pen is very similar to a medium strength cig.  Being an ex smoker of Marlboro reds, I would say that the draw is not as restrictive as those, but definitely more restrictive than a Marlboro light.

Juice Consumption

The wife and I went out on a road trip along the North Coast of Northern Ireland. Whilst driving and chain vaping on the Jem Pen for over 6 hours, I only had to refill twice, making this an extremely economical vape.

Vapour Production

This is a MTL device, so vapour production is not huge and not supposed to be but it’s comparable to other MTL device/Tanks.

Battery Life

The 1000 mAh battery under a full charge should last you a full day, constant chain vaping will give you around 6 hours of use.Innokin Jem Pen outdoor image

Charging the battery couldn’t be simpler, plug in the Micro USB cable and walk away, you will not be able to use this device while it is charging. To get the battery fully charged will only take a couple of hours.

Pros

  • Good Build Quality
  • Excellent Flavour
  • Easy to use
  • Fits in any pocket
  • Good Battery Life

Cons

  • Drip tip could prove difficult to open

Final Review Verdict

I vape both MTL and direct to lung (DTL) but when sitting at home or driving the car I enjoy a nice MTL vape.

I have thoroughly enjoyed using the Innokin Jem Pen and will continue to carry it around when out and about.

Although aimed and beginners/new vapers, even a hardcore vaper will find this MTL device quite enjoyable and simple to use. The only issue I have is with the drip tip, as I mentioned, it can be quite difficult to unscrew, just try not to over tighten it, when you start to feel resistance stop tightening it!

Ken The Diabetic Vaper
Vaping since 2015, I started an Instagram page dedicated to the vape that has over 2k followers and climbing. A fan of all things tech (Geek and Proud), vaping was a natural step as it included both nicotine and technology. I started vaping with a simple budget pen setup, now, vaping is my main hobby and I'm passionate about getting people to switch from smoking to vaping.

    • Hi Manuel,

      What exactly is happening? is it powering on? Are the LEDs appearing on the button? Have you charged it?

      Quite a few more possible questions, can you give me a bit more info?

      Thanks
      Ken

  1. I bought this pen. This is my first vape pen. I followed the instructions on how to set it up: put in the coil, put in the liquid, and charge. However after leaving it stood up charging I’ve come back to it and found all the liquid has leaked out. How? What did I do wrong?

    • Hi Chris, sorry to hear that, coming back to any device and finding a pool of juice can be one of the most annoying things ever!

      Can I ask, was the coil screwed into the device tightly? Did you feel any resistance when you started screwing it in? It could be possible that the coil didn’t thread properly into the pen, sometimes it is useful to do a few reverse turns to make sure the threads grip.

  2. Great video mate, i ve already watched many reviews on Youtube and i am pretty sure that is a great device for mtl users like me. Just a question please, how long does it take for a full charge when is almost dead of battery and if u can wash up the drip tip and the tank without the coil of course if u wanna change a liquid flavour. Thanx in advance, great job.

  3. Been using it for the last 3 days and I really love this elegant MTL buddy. An affordable device with such a great performance. Zero dry hits, restricted the way I prefer and gives a lovely flavor. My only complaint is that you can’t replace the drip tip.
