Smok’s line of Osub products are mods that come with Baby Beast tanks or the Helmet Nano tanks. These products are the King, Mini, and Baby. What makes these vapes stand out is their build and design quality, excellent to average battery life, and the tanks with which they are paired.

Each mod and its respective tank produce outstanding flavor and a respectable amount of vapor. Plus, they are suitable for vapers who are always on the go.

Smok Osub King 220w TC Kit

The Osub King is a 220w temperature control mod that is part of the Osub series of mods. This vape uses dual 18650 batteries to heat the coils inside of the TFV8 Big Baby Tank, which comes with the starter kit. The King also has a C-shaped lateral firing bar, and it also has a small screen for monitoring the status of the vape. The batteries can be accessed by opening a hinged, sliding battery cover that is magnetized to ensure it stays shut. The Big Baby Beast Tank complements the mod very well, having a large capacity, excellent airflow, and an efficient refilling system.

Another feature in this vape that stands out is its integrated chipset, which allows it to fire to 220 watts. It also has extensive temperature control settings and safety features that allow for a comprehensive and danger-free vaping experience. The chip also allows for better responsiveness from the controls and faster heat up time.

One of the most important features is the flavor and vaping quality, and this mod and its tank do not disappoint. The tank uses Q2 and T8 V8 Baby coils. The Q2 coils are for vaping between 40w and 80w, while the T8 coils are for between 50 and 110 watts. There are also different styled coils that can be bought separately. Also, because the mod has a 510 connection, it can support different tanks if the flavor and vapor quality are not what the user expected.

Starter Kit

The starter kit includes the mod and the Big Baby Beast Tank, two coils, and a USB cable. Also included are a bag of spare parts and an instruction manual.

Build Quality and Design of the Kit

The quality of the manufacturing is excellent, which is what one would expect from Smok. The main difference between this mod and others from this company is that it is bigger because of the dual 18650s. The design is straightforward, and the screen is smaller than the others now on the market. The firing button is very responsive, as are the two adjustment buttons. The adjustment buttons are too close together, making it easy to push the wrong one accidentally.


The battery life on the King is excellent. When the mod is fully charged, the user can vape for seven to eight hours on moderate wattage levels before needing to recharge it. This device’s long battery life makes it ideal for extended outings away from a house or flat.


The Big Baby Beast Tank is 24.5 mm in diameter, so there is no overhang. It also holds 5 ml of juice, and it has a convenient top-fill design with a hinge locking system. The airflow is excellent, having dual adjustable airflow control at its base.

At the top, there is a black and super-wide Delrin drip tip. Inside, the tank uses the patented Baby Turbo Engines Coil structure. Also, it uses 0.4 ohm and 0.15-ohm V8 coils. The construction quality is superb thanks to its stainless steel construction and high-grade reinforced glass.

How to Use the Starter Kit

This mod is easy to use. Click the firing button five times to turn it on. To turn it off, cycle through the menu, and choose the power off option. The mod can also be turned off by locking it and holding down the firing button. In the menu, the user can choose between different vaping modes, like temperature control, wattage mode, and different strengths like hard, soft, etc.

Smok Osub Mini Kit

The Osub Mini is a smaller version of the Osub starter kit. The main differences are that it has a smaller size and that the internal structure has been optimized. The vape can fire to 60 watts, and it is capable of operating as low as 0.1 ohms. An internal battery powers the device so that the user does not have to worry about carrying spare batteries. Besides these specifications, the mod has multiple safety features built into the design, including short circuit protection, 12-second cut-off, and overheating protection. There is also an LED indicator that shows when the battery is running low.


The starter kit comes with a Helmet Nano Tank. What makes the tank stand out is its unique design that includes a highly innovative airflow system that significantly improves flavor and cloud production. Additionally, the tank is sturdy, so the user does not have to worry about it breaking or malfunctioning.

Of all the features incorporated into this mod, the best is its small size and ergonomic design. It measures 120 x 30 mm, and it only weighs 145 grams. This mod will fit anywhere on a person, whether it is a pocket, purse, or backpack. Since it is so small, it is ideal for sitting in a shirt pocket. Also, it fits comfortably in the palm. Appearance-wise, it is a cool looking mod.

Starter Kit

The starter kit has everything a vaper needs. It comes with the vape, and it has one Hemet Nano Tank, two coils, a USB cable, spare parts, and a user manual.

Build Quality and Design of the Kit

There are a lot of things to like about the build quality and design of this vape. Firstly, it has a very clicky and huge firing button.


The construction quality is outstanding, too. The tank is made out of stainless steel, and the mod is made out of zinc alloy. Do not expect it to fall apart soon after buying it.


A 1200mah internal battery powers the Mini. This battery is powerful enough to allow the user to vape much of the day without having to worry about it dying. Refill the tank by adding juice through the central slot. Afterward, let the tank stand for several minutes so that the coils and wicking have time to prime.


The Mini uses the Helmut Nano Tank, and it holds 1.7ml of juice. It is 510 threaded, making it compatible with a variety of mods. One of its most unique features is its top airflow system. This design allows two air streams to converge on the coil, resulting in improved flavor and vapor.

SMOK OSUB Mini tank

The tank fully seals, meaning that it does not leak. Two coils come with the tank. Choose between the 0.6 ohms Helmet-Nano or the Helmet-Nano CLP 0.4 ohm coil for mouth-to-lung vaping.

How to Use the Starter Kit

To use the vape, press the power button five times to turn it on or off. Press and hold the firing button and inhale to vape. Release the button when finished vaping.

Smok Osub 80w Baby TC Kit

The Osub Baby is a pocket vape that is lightweight and ideal for beginner vapers or those who want something portable. This compact and portable mod runs on a single 18650 battery that allows for vaping between 0.1 and 80w. Like the King, it has a C-shaped firing button that encompasses the length of the mod. The frame has a bright and discernable OLED screen built into it that shows the user the mod’s status. Two highly responsive regulatory buttons are below the screen, as is a USB port, which is used for charging the mod.


Several features are incorporated into this mod that significantly improves the vaping experience. The vape has atomizer recognition and a highly efficient chip set. The chipset allows for temperature control and variable wattage vaping. Temperature control is compatible with nickel, stainless steel, and titanium coils. Regardless of whatever settings are chosen, expect to get consistent flavor and vapor production at all times. There are also a multitude of onboard safety features, which include 12-second cut off, short circuit protection, and low battery warning.

The Baby Osub kit is an excellent compromise between the King and Mini. The mod has slightly more power than the Mini, but it is smaller than the King. It has many commonalities with the other mods, too. The mod is easy to use, comfortable to hold, and very ergonomic. This vape is suitable for people who want something that is convenient, affordable, and fun to use.

Starter Kit

The starter kit comes with a lot of stuff. It has the main items like the mod, tank, coils, and USB cord, but it also has a user manual and a warranty card. Also included are spare parts like vape bands, spare o-rings, and an extra juice inlet.

SMOK OSUB Baby kit

Build Quality and Design of the Kit

The build quality of this mod is superb. The 510 connection is made out of stainless steel, and it is spring-loaded. Almost every atomizer sits flush on the mod as long as it is not bigger than 22 mm in diameter. The firing button is very clickable and responsive, and the two adjustment buttons are decently sized. The OLED screen is bright, and it displays all the information in easy to read letters. Additionally, The battery compartment has a latch that is secure and never opens.


A single 18650 battery is used to power the vape. Battery life varies depending on the settings on which the vape is operating. If good quality batteries are being used and the vape is on 60 watts, expect to get five to six hours of vaping time.


The mod uses a Baby Beast Tank with 3 ml of juice capacity, and it uses a trademark swivel-cap top filled system. It also has an adjustable airflow system with two colossal airflow slots. There are no issues with leaking, and it is easy to remove the coils. The threading for the coils is very smooth, so there should be no issues with coils getting stuck.

How to Use the Starter Kit

The vape is quite easy to use. The wattage can be adjusted in 0.1 and 1.0-watt increments. While in temperature control, it can be increased 5 or 10 degrees depending on whether it is in Celsius or Fahrenheit.

Clicking the firing button three times brings up the menu, allowing the user to choose the mode, TCR, and several other settings. To turn the mod off, select the power option in the menu. Next, click the firing button five times to lock the mod, and then squeeze the trigger for five seconds.

Smok Osub 80w vs. iJust 3 Kit

The iJust 3 is a vape that comes with a 2 ml tank and powers up to 80w. There are a few differences between these vapes.

The main difference is that the iJust 3 is powered by a 3,000 mah internal battery, while the Osub Baby uses a 18650. Another difference between these mods is their exterior design. The iJust 3 looks like a long tube, and it is slightly more portable than the Osub Baby.

Which Osub Starter Kit is the Best?

It is difficult to say which is the best Smok mod because each is different. The Osub King is an excellent mod for people who want to vape on high wattages, while the Osub Mini and the Osub Baby are smaller and slightly more portable. But, if forced to choose one, it is probably best to select the Osub King because of its higher wattage range and better battery life. But, all of these mods are excellent. They are built to a high standard and produce excellent vapor and clouds.

I love the written word, and in my career as a journalist, I strive to provide the facts about everything I write about. There are too many false and alarmist stories out there about life and vaping mainly. My mission is to make e-cigarettes less scary to people with informative articles and extensive research on not only the possible evils of cigarettes and Big Tobacco, but the objective side of e-cigs.
