SMOK OSub styling and build quality

The first things you notice about this device is that it is attractively stylish and also very lightweight due to its Zinc Alloy construction. The design has very nice clean lines and all of the edges are well rounded so it feels very comfortable to hold!

Like most SMOK devices the OSub has a trigger fire bar/button and while I am not usually enamoured with this particular style I think this is probably the best one that SMOK have ever done because the amount of tension when squeezing it feels absolutely perfect to me and it is really pleasant to use. Sadly it is not quite perfect because it does occasionally stick a little (maybe it needs some WD40), hopefully that fact only applies to some of these models.

What is very interesting is that the device has no obvious Micro USB Port because it does actually have one uniquely concealed under the trigger fire/bar which is actually removable and held on by magnets. It’s a really good way to reduce the amount of visual clutter and it also helps to keep it away from either rain droplets or juice from a particularly leaky atomizer.

One the side of the device near the top you will find the OLED display which is both bright and clear and even though it is quite small it is still very legible. Just like other SMOK devices the menu users an icon-driven system and you can make adjustments with the discrete plus and minus buttons located directly beneath the screen.

At the top of the device you will find the spring-loaded 510 pin which looks to be made from brass. I had no issues fitting various atomizers that I own to the OSub and all of them sat flush. Given that the top of the device isn’t exactly huge any atomizer with a diameter greater than 25mm will look a bit silly and since the OSub is very compact taller tanks like the Freemax Scylla and the Kayfun 5 can also look extremely odd when fitted.

I received the white and black version for review and it really is a beautifully presented little device with a really nice finish that looks to be durable. This also matches up perfectly with the white version of the Helmet tank which is included so you can look quite the vape gear fashionista when you are using it!

The device features a 1350mAh internal battery which has to be charged via the included Micro USB cable. Sufficient venting is provided in the base by five small air holes.

Ease of use

The device itself is very straightforward to use and the manual is decent so you are unlikely to run into a problem. Variable Wattage Mode and Temperature Control Mode both work well and without issues.

Press the firing key three times quickly to enter the menu. You then scroll through the various options with the plus and minus adjustment buttons. Confirm options with the firing trigger.
As with many mods you can also rotate the screen to your preference, make TCR adjustments and also lock the device by pressing the plus and mius buttons simultaneously.

SMOK OSub 40W performance

Since I have already reviewed the Helmet tank in detail I am only going to briefly mention it here. The vape it offers is decent in terms of flavour and it can put out some good cloud production but it does have some minor issues. Firstly take care not to fill the tank higher than the indicated level or the liquid will be displaced when you fit the top cap. Secondly you are stuck with the included drip tip which will disappoint some users and the tank is restricted to 2ml capacity thanks to the TPD. The clear plus points of this tank is the fact that it vapes well, is easy to use and it has a child lock feature which will give parents peace of mind.

While the included 0.4ohm Clapton dual core coil does offer a very satisfying vape it will drain the tanks 2ml capacity rather fast so you will have to refill often and what’s more it does heavily reduce the device’s battery life. I have read some accounts of people saying that they got a satisfactory vape at 25 Watts with the 0.4ohm coil but that certainly wasn’t true in my case and I had to ramp up the Wattage to 34 Watts to get what I would call a good vape. This means that you might only get three hours use out of the device if you are a heavy vaper before it needs recharging so it is fortunate that SMOK also include a 1.0ohm coil with the device.

I did not actually make use of the 1.0ohm coil but since you need far less power this will increase the longevity of the battery and you also will not drain the liquid as quickly.

Lastly I briefly tested out the Temperature Control Mode. I used my Sense Herakles Sub Ohm tank which is fitted with a Ni200 Coil and the OSub seemed to perform as you would expect with no noticeable problems. The only issue was the Wattage limitation of the device since the Herakles tends to need about 45-50W when using the Ni200 coils so the vape was slightly lacking at the maximum 40 Watts, however you wouldn’t typically use something that needed that much power on the OSub and I only used it because it was all I had to hand.

The OSub 40W does have one minor annoyance every time it comes out of standby mode and that is the fact that you do have to confirm whether you are using the same coil or not. In terms of accuracy it is a good thing that the OSub does this but it can be irritating when you reach for the device and press the fire button only to discover that you are not getting a vape until you once again let it know that you are still using the same coil.

As mentioned earlier the battery life depends entirely on how often you vape and which coil you decide to use in the Helmet tank. In some ways I feel that the device would be even better if SMOK had fitted a 2000mAh rather than a 1350mAh especially when they include a tank that can be fitted with a 0.4ohm coil which can be a significant drain on the battery.

Conclusion

Apart from a slightly small battery capacity and one very minor annoyance when the device goes into standby mode I feel that the SMOK OSub is an extremely well made and very worthwhile product. It is small enough to fit in the pocket, feels extremely nice to use and the Helmet tank does offer a pretty good vape!

If a compact and reliable device with nice aesthetics is what you are looking for then this one is well worth checking out!
