SMOK Osub Introduction
The SMOK Osub 40W vape mod is another new device from Smoktech! There are many vape companies releasing product on a regular basis but SMOK are leading the pack with what seems like bi-weekly hardware releases.
Is this a good thing? As long as the product is top quality and not rushed then why not. We, as vaping consumers, have a choice on whether to buy after all.
So back to the Osub kit with the included Helmet tank. This is targeting the popular resurgence of the mini vape mod market. An area I personally like a lot as I vape when I’m out a fair bit so appreciate a stealth vape setup!
Before we jump into the review let’s see what SMOK have to say in their marketing material. I always enjoy their descriptions, this has to be the strangest yet though 🙂
NEW FAVORITE IN JACK‘S POCKET
It’s time to throw away the Zippo
Ring, ring, ring. “Honey, Yes, I’ll be there on time!”that is Rose. Jack hung up the phone and took the coins, keys from the table; when his eyes fell on Zippo, he paused for a few seconds, and then he took the OSUB next to the Zippo and put it into his jeans pocket; while,the Zippo, used for 3 years, was been thrown into the trash can. “It’s time to throw away the Zippo.” Jack said to himself and whistled excited to attend his girlfriend – Rose’s birthday party.

Design and Build Quality
Size and Finish
The SMOK Osub is, as mentioned already, is a mini box mod and it really is a great size. The weight is good, not too heavey, but enough substance to it to make it feel a quality product.
It can easily be hidden in the palm of your hand and I have small hands.
Slipping it in and out of your pocket is easy due to both the size and finish.
Here is a picture of the SMOK Osub vs Artery nugget Vs Kimsun 40W TC Vs Eleaf istick PicoThe Osub is made from zinc alloy and the stainless steel version I have been using for this review has a smooth, slick finish.
It’s similar to what I remember on the X Cube 2 and I wasn’t a massive fan of the finish on that.
Same has to be said for this. It’s hard to explain but I’m just not a fan of the way it feels.
It picks up fingerprints quite easily and leaves an almost greasy feel like the oils of the hand are transferring too easily to the mod iteslef.
Maybe not the best description, or maybe I just have sweaty palms!
It has to be said the other finishes (Black, White, Black/Gold) are good for me and don’t attract the oils from the hand as much.
Design and Features
The thing I like most about the Osub is the fire button. It’s located under the side grip at the top of the mod so all it takes is a gentle palm squeeze to fire up.
This is a feature I have been seeing on a fair few vape mods of recent and it’s a feature I really like. The SMOK Quantum, H Priv mod and the Eleaf iStick TC100 have a similar fire button and all work great.
One thing to keep in mind, however. The SMOK Osub fire bar, I have found, is super sensitive. On numerous occassions I found myself accidentaly firing this.
There is a locking function on the mod which is activated by clicking the fire button 5 times in quick succession.
So just be sure to get into the habit of using this!
At the top we have the 510 threading and adjustable pin. The front, flat side of the Osub feautures the OLED screen and two function buttons. The OLED screen is small but clear and easy to read while the function buttons are rounded and finished well.
There is rattle on the buttons when brushing your finger over them but nothing when giving the mod a gentle shake.
The reverse side features simple branding and the base 5 battery vent holes.
So where is the USB port on the Osub?
Good question. This is where a new design feature comes in. The side panel grip that doubles as the fire button, which SMOK call the battery cover, not sure why, is removeable.
The panel is held firmly in place by magnets. On removing the cover you will find the micro USB port. A nifty little feature. Although not sure how useful it is or the real purpose it serves.
It’s likely just to keep the lines of the device clean and clutter free or maybe SMOK are planning to release the removable plates as an accessory so you can change the colour?
Helmet Mini Tank
The 22mm diameter Helmet Mini tank is a new design from SMOK that comes with a completely sealed U shaped chamber and top fill design.
The capacity is 2ml, which is to be the maximum allowed in the UK due to the TPD regulations.
The tank has a child proof locking feature that works as it should. Similar to any child safe bottle, it’s a case of pushing down and screwing/unscrewing. Easy and effective.
Filling is easy, the whole top cap can be removed leaving a near 22mm diameter hole to fill through. Even the most clumsy vapers shouldn’t have an issue with spillage here!
The only thing you need to look for is a 2ml e juice level marker on the side of the tank. It’s there for a reason! Going over this too much will result in overflowing and leaking.
The windows are big and clear so you can see remaining juice levels easy enough.
The coil heads themselves are screwed into the bottom of the top cap. This is then simply dropped into the tank and screwed into place.
Overall a well built tank.
How Does The SMOK OSUB and Helmet Mini Tank Perform?
We will first take a look at the SMOK Osub mod functions and how they work.
- Lock/unlock – 5 clicks of the power button
- Enter menu – 3 Clicks of the power button
- Menu select – Use function buttons to scroll through options – Use fire button to select
- Lock in settings – To lock your settings press both function buttons together. Press again to unlock.
- Quick select (VW/TC mode) – Click up function and power button together to select wattage or temp quickly.
- Select wattage outpu for TC – Press down function and power button together to enter wattage select.
The menu system is straight forward to use and allows you to change and access the following:
- Power mode
- Coil type selection – Sub menus for TC coils allow you to change watttage output and fine tune the actual coil resistance (advance use only)
- Screen display time (10-240 seconds)
- Puff count – Displays puffs – Can be reset here
- Screen rotate – Left Or Right
- Coil adjust – Adjust resistance of coils
- Turn mod on/off
When removing/replacing your tank, the mod will also require you to select whether the coil is a new one or not. You will need to remember to go into the settings here and select your coil type, if of course you have changed it.
All of the features you need but one surprising ommission. SMOK, for some reason, have decided not to add any firmware upgrade option. Or at least from what I can see.
It’s a strange decision considering the SMOK Quantum mod, that was released just a few weeks before the Osub, feautures wireless upgrade capabilities. SMOK are also pushing their Vaping Tour app at the moment as well.
The 1350 mAh battery isn’t going to be entering the Guiness Book of Records for it’s battery life. But the same can be said for any vape mod in this class. Just keep in mind the intended use for the Osub.
It’s a mini mod that provides you with a super portable device that isn’t going to stand out like a sore thumb.
I found myself using the 1.0 Ohm coil the most and the battery life was decent. The 0.4 Ohm tank did drain the power pretty quick though.
When I’m using a mini box mod like this I tend to use a tank such as the Apsire Triton Mini or Nautilus X. The higher resistance coils operate between 10-20W allowing for an extended battery life.
Helmet Mini Tank
SMOK have always impressed me with their coil heads and the Helmet tank coils are no different. The flavour was good from both and cloud production decent. I was vaping Black Note Prelude and the flavour notes showed well to provide a good vape.
The coils are on the thirstier side, however, nothing close to the TFV8.
In the package there are some orange O ring bungs/stoppers. SMOK recommend these are added to reduce the airflow and increase flavour.
They just sit on top of the cotton in the coil (as can be seen above) and I actually found the flavour did improve a touch with these. Airlfow wasn’t effected too much though.
The airflow works by twisting the top cap. It twists 360˚ and clicks into place when the airflow is fully open. When fully open it’s quite an airy draw but not too airy.
Fully closed the draw is tight. I didn’t get a very good mouth to lung vape with it closed so personally just used this fully open all the time.
The airflow is a bit strange in that the only way I knew it had closed to it’s maximum amount was to suck through the drip tip while turning the top cap.
When it reached it’s most restrictive draw I then new it was closed off. Reminiscent of using a combination lock on a safe, adjusting back and forth until you hit the right setting.
The drip tip features a V shaped airflow channel that gets narrower down into the drip tip iteslf. I can’t honestly say I noticed if this made a big difference to flavour of vapour.
With the former being good and the latter decent I guess it’s doing something right.
What I like
The big thing for me with the Osub tank is the form factor. It’s very compact and easy to carry around in a pocket makin it a prefect vape mod to use when you are on the go.
Build quality is excellent and the hidden fire button makes vaping with the mod easy with a squeeze of the palm.
The helmet tank performed well overall with no leaking whatsoever.
Battery life was good when used with standard resistance coils ie: around the 1.5 Ohm mark.
What I Didn’t Like
The tactile finish on the stainless steel version wasn’t to my liking, the mod seemed to pick up oil residue from the palm creating a strange slick feel to the zinc alloy.
There is no upgrade capability with the Osub. Maybe not a big deal for some vapers.
Battery life, as would be expected with a 1350 mAh battery, is not great when sub ohm vaping.
Coils were a little on the thirsty side. Not TFV8 thirsty, however!
I also found the fire button to be super sensititve. Could just be that I was being a bit heavy handed and you can lock the device. If you do the latter it’s not an issue.
Final Review Verdict
