Innokin Jem AIO Pen Kit Review

Innokin Jem AIO Pen Kit Review

Innokin has established themselves over the years as an excellent manufacturer for beginner devices. With a vast experience in creating MTL AIO devices, the Jem AIO Pen Kit has quite the legacy to live up to. As many reviewers noted, this little kit is very much a throwback in both aesthetics and design intent. You’ve got a sleek, pen-style chassis with everything you need to get started built right in. If it works well, this is exactly the kind of thing beginners are looking for. For that matter, even the experienced vapers out there need something to take with them on the go, so let’s take a look at how the Jem AIO Pen Kit stacks up.

The Jem AIO Pen Kit really does have a lot going for it, but there’s some important qualifications to get out of the way right up front. [Spoiler Alert] It’s easy to recommend this device, but it’s not going to be for everyone, and more experienced vapers may have some particular bones to pick. Let’s start off with the cons before we get to the pros.


The drip tip and the top cap are both constructed from plastic, which is going to be a big con for a lot of people, especially those with the experience to expect a little bit more from their vape devices. If you’re new and asking what the big deal is; plastic top caps threading into metal run the risk of cross-threading and stripping the cap. That is, if you aren’t careful and screw this thing in at an angle, you’re going to ruin the whole top section of the device. Without any spare parts included in the package, you’re basically going to have to buy a whole new kit if that happens. Furthermore, the drip tip and top cap are all one piece, meaning you’re stuck with Innokin’s drip tip. A lack of customization is going to be a big con for certain vapers, but is likely to be perfectly acceptable to beginners.


While the constant output on this device is going to be a big pro, it’s also got to be mentioned as a con. While it is far more constant than just about every unregulated device out there, you will notice a drop-off after the battery gets into the red, indicating that it is not entirely constant. Again, this isn’t the end of the world, but it’s certainly worth noting.


The airflow is also fixed, further limiting the customization options that experienced vapers might be looking for. Again, for the coils included in this kit, the airflow is going to be just about perfect but it’s still kind of annoying for anyone looking for that option. No matter how nice the airflow is, people are going to want to adjust it and this option is becoming increasingly standard. Why not give us the option, Innokin?


The rest of the issues are pretty minor: the LED indicator’s color scheme is not going to be particularly friendly to colorblind people (but if you’re colorblind, you’ve likely already accepting this as standard), and the charging takes a fair while too.


What really sells Innokin’s Jem AIO, however, is the fact that most of these cons have an equal and opposite pro to go along with them. For instance, it takes a while to charge, but this is due to a 1000mAh battery built in. That’s going to provide you a ton of battery life, given the high resistance coils you’re going to be using. By most reports, you’ll be able to get through an entire day of relatively heavy vaping with only a single charging session in the middle.


Remember that one-piece plastic top cap? Fortunately, it’s hiding a really nice and easy fill system. You get two extra-large kidney holes underneath the top piece, which will easily accommodate just about any bottle you can throw at it. The airflow provided by this kit is also absolutely perfect for the beginning vaper, or people fresh off cigarettes. You’ll get that super-tight MTL draw that so many beginners are looking for. This is an important point, however, since there’s no adjustable airflow. If you don’t like super tight MTL draws, this is an automatic pass for you.


Then, there’s just about everything else. The whole kit is super simple and stripped down. While we may gripe about a lack of features, this kit should check just about every box on a new vaper’s checklist. There’s no complex features to navigate, nor does it require any in-depth understanding of vaping. You get quite good flavor, you get two coil options, you get a nice, warm, and satisfying vape – it really covers all the bases very well.


Final Thoughts

At the beginning of this review, I touched on who this kit might be for, namely: beginners and vapers looking for a portable stick option. By the end, however, it’s clear that this device is really only suitable for the beginner. Beginners will likely be drawn to its similarity to cigarettes and its ease of use. Advanced users will likely be turned off by its lack of features and customization options. For that market, there are far better choices which provide greater control over the vape experience without sacrificing portability or compactness. For beginners, however, the Jem is easily among the very top 5% of vape devices. If you or a friend is trying to quit smoking, toss them one of these – they also come at a great price point of roughly $20. Not bad, Innokin.
