SMOK OSUB 80W Baby Kit Review | OSUB Family’s New Edition

Is this new or just deja-vu?

SMOK is nothing if not prolific. It can be confusing keeping track of products and coil types, as the company tends to take an initial design and then produce variations on that theme. A good example of that would be the TVF8 family of tanks. There are at present three distinct versions of the TFV8 tank, with 25 different coil types! The OSUB family is no different. What sets the OSUB series apart from other SMOK products is their C-frame construction, clicky firing bar, and small but bright OLED display.

The OSUB 80W Baby kit feels very much like the OSUB Plus kit revisited. The 80W kit comes paired with the 3 mL TFV8 Baby tank, and boasts the same good looks of its OSUB cousins. The main difference is size. Gone is the internal battery, and with that, a bulk of the width. As its name suggests, the OSUB 80W Baby kit powers up to 80 watts on a single 18650 battery. I’ve seen the kit on pre-sale for under $50. Let’s road-test the OSUB 80W Baby kit and see how it fares…

Disclaimer: We received the OSUB 80W Baby Kit from SMOK for the purpose of this review.

One of our samples arrived with a hardware defect that impacted on the voltage range. We have been informed by SMOK that this is a beta version and retail models will be checked carefully before sale.

Notable Remarks

Unboxing

SMOK Osub 80w baby kit

The OSUB 80W Baby kit comes in SMOK’s standard packaging, complete with warranty card, manual, and a couple extra o-rings, vape bands, and spare juice inlet. The bundled TFV8 Baby tank has been packaged this time with two V8 Baby-Q2 Core (0.4 ohm dual) coils. These are the same coils that were paired with the Brit Beast tank in the OSUB Plus kit, and are labelled as operating between 40 – 80 watts. It’s a testament to how versatile the TFV8 Baby tank is – whack a different coil in there and it performs consistently, whether at 50 W, 80 W, or as an RBA. A spare glass tank is conspicuously missing, however.

The OSUB 80W mod feels very comfortable for me as a left-hander, since the fire button can be finger activated while the bulk of it rests in my palm. In this position, the OLED display and up/down buttons also feel most logically arranged. Bear in mind your up/down buttons will also reverse if you flip the menu screen (through the settings option).

The OSUB mod is made from zinc alloy, and has a matte, fingerprint-resistant finish. The whole construction is free from button rattle. The firing bar is highly responsive; about 2/3 of the bar is clickable, from the top down. The battery compartment door is activated by a small latch, and springs open. The battery polarity placement is marked at the far end of the battery compartment. Unfortunately, there’s no marking on the inside of the door, but you can’t miss the large positive marking when inserting an 18650 battery. Overall, the battery compartment is secure and won’t swing open unexpectedly. However, the grooved latch makes it far easier to open than the push-and-slide construction of the Skyhook RDTA or G320 kits.

The only thing missing are dedicated battery vent holes. Perhaps the latch inset holder offers a small window of sorts, but otherwise, I see no way for the 18650 to vent.

It is possible to charge the OSUB 80W mod via the micro USB port. That didn’t work for me tethered to a computer, but I did get a charge connected directly to the wall socket. SMOK offers 1 amp charging for this device, a standard that is already being outpaced by competitors. However, I would still maintain it’s safer to charge your 18650 batteries through an external, dedicated charger.

Menu functionality

SMOK Osub 80w baby kit

SMOK manages to squeeze their functional menu interface into precious little real estate here. The device powers on and can be locked with five clicks.

Watts are adjusted in .1 or 1 watt increments, either by clicking the firing bar once (.1), or holding it (1 watt). In TC mode, Celsius can be adjusted in 5 °C increments, Fahrenheit in steps of 10 °F.

Three clicks takes you to the different menu options: Mode, Puff, Adjust Ohm, TCR, Setting, and Power.

Under Mode you can toggle between wattage and temperature control mode, selecting from five different draw strengths and wire types (Ni200/Ti/SS).

You can also round-robin between Celsius and Fahrenheit in TC mode.

The Puff menu displays your total number of inhales, has a limiting function, and allows you to reset the counter.

Under Adjust Ohm you can alter the exact resistance of your coil to three decimal places.

TCR allows you to finetune the resistance of your TC wire type.

Under Setting you can enter stealth mode, change your screen timeout interval, adjust contrast, and flip the menu orientation.

To power off the device either go to Power through the menu, or click the firing bar 5 times to lock the device, and then hold down the bar for 5 seconds.

New tanks are automatically detected by the system, and need to be confirmed before you vape on them.

How it performs

SMOK Osub 80w baby kit

The TFV8 Baby Beast has already been reviewed in depth by Bill. I am quite happy with the performance of the Q2 coils. I personally enjoyed them around 65 W, keeping the airflow wide open. As is typical with the Baby Beast tank, it produces bundles of vapor and flavor, and feels like a decent all-round marriage of the two. I also know that I could use the TFV8 Baby tank with the (not included) RBA core, and it would function perfectly within the 80 W range of this device. As a last thought, the Baby Beast is a thirsty tank, even at lower wattages, so it would make sense to carry some e-liquid around with you.

On to the OSUB mod, then. There is very little that sets the OSUB 80W mod apart from the OSUB One and OSUB Plus kits. It brings the skillset of the OSUB Plus to the table in a smaller form factor. As a mod, it’s suitable for any 22 mm tank or rebuildable without overhang.

You might not find a single 18650 adequate for ADV at higher wattages. But at least replacements are easy to carry around (in a case, please!) I’m not aware of any firmware updates currently available, but as and when they are, the micro USB slot next to the OLED screen is side-mounted for easy access.

Likes

  • Great build quality
  • If you’re left-handed
  • the OSUB family is made just for you
  • Clicky firing bar
  • SMOK menu functionality (adjusting ohm resistance and puff counter)
  • Comes bundled with one of the most versatile tanks on the market

Dislikes

  • UI orientation is odd for a majority right-handed market
  • Feels more like a rehash than any real innovation
  • No venting holes?

Verdict

Basically, what we have here is the OSUB Plus kit with the width shaved off. The C-frame construction will be a hit for some people. The lack of an internal battery may be the deciding factor for others. But I feel that your choice to get the OSUB 80W Baby kit – or not – will come down to aesthetics. Because in technical terms, the ground is already well worn.

SMOK produces so many variations on a given theme that it can be confusing separating the “must-have” purchase from the superfluous. We’ve seen the OSUB family of devices already. And what the 80W version does, it does pretty well. However, there are no surprises here. This feels like consolidation of a proven product line rather than any real innovation in the field.

Personally, I think there are already plenty of devices – many of them from SMOK – that offer the same skillset as the OSUB 80W Baby kit. Recommended – but only if you are desperate for a left-handed, single-18650 80 watt box mod kit!
