The JUSTFOG Q16 Pro kit is a compact electronic cigarette designed for simple vaping with mouth-to-lung MTL inhalation. It combines a built-in 900 mAh battery with the 1.9 ml Q16 Pro clearomizer, featuring adjustable airflow and four voltage levels for easily adjusting vaping intensity.

Supplied with a 1.6Ω JUSTFOG 14 Series coil, the Q16 Pro operates at low wattage and can deliver up to approximately 12W. Its top filling, simplified settings, and especially compact design make it a kit primarily intended for users looking for a tight draw without complex menus.


🖋️ A compact and discreet design

The Q16 Pro has an especially slim design, with a clearomizer measuring just 16 mm in diameter mounted on a compact battery.

The complete kit measures approximately:

  • Height: 130 mm
  • Width: approximately 22 to 25 mm
  • Thickness: approximately 16.5 mm
  • Weight: approximately 60 g

These dimensions make the Q16 Pro easy to carry in a pocket while maintaining a comfortable grip.

The battery features an anodized aluminum finish, while the clearomizer combines metal with a transparent tank to make it easier to monitor the e-liquid level.

The Q16 Pro is available in several colors depending on the series:

  • Black
  • Silver
  • Blue
  • Pink
  • Gold
  • Red

🔋 Built-in 900 mAh battery

The Q16 Pro battery has a capacity of 900 mAh.

This battery life is consistent with the low wattages used by JUSTFOG coils in the 14 Series range and with the kit’s MTL design.

Actual battery life depends in particular on:

  • Selected voltage level
  • Coil resistance used
  • Duration of inhalations
  • Frequency of use

A low voltage setting naturally uses less battery power than consistently using the maximum level.

⚡ Micro-USB charging

The battery can be charged directly via a Micro-USB port.

The necessary charging cable is included in the kit.

Since the battery is built in, no external battery or dedicated battery charger is required to use the Q16 Pro.


⚙️ 4 voltage levels up to approximately 12W

The Q16 Pro has no screen or complex wattage adjustment. Instead, JUSTFOG offers four preset voltage levels.

Pressing the adjustment button allows you to select the following in sequence:

  • 3.5V: 1 LED
  • 3.8V: 2 LEDs
  • 4.1V: 3 LEDs
  • 4.4V: 4 LEDs

With the supplied 1.6Ω coil, these settings allow you to gradually adjust vaping intensity without having to enter a specific wattage manually.

The maximum setting of 4.4V corresponds to a power output of approximately 12W with a 1.6Ω coil.

Increasing the voltage generally makes the vape warmer and more dynamic. A lower setting, on the other hand, provides a smoother vape while reducing battery and e-liquid consumption.


💡 LED indicators for the settings

The lack of a screen is offset by several LED indicators.

The four LEDs located near the adjustment button indicate the selected voltage level.

Another light indicator also lets you monitor the battery charge status:

  • White: high battery level
  • Blue: medium level
  • Red: low battery

This interface displays only the essential information without requiring navigation through different menus.


💧 1.9 ml Q16 Pro clearomizer

The kit comes with the JUSTFOG Q16 Pro clearomizer, with a capacity of 1.9 ml.

Its 16 mm diameter perfectly matches the compact format of the Q16 Pro battery.

The clearomizer features:

  • A 1.9 ml tank
  • Top filling
  • Adjustable airflow
  • A replaceable coil
  • A 510 drip tip
  • A 510 connection

Unlike pods using a cartridge with an integrated coil, the Q16 Pro allows you to keep the clearomizer and replace only the coil when it reaches the end of its service life.

⛽ Convenient top filling

The Q16 Pro clearomizer uses a top-filling system.

To fill the tank:

  • Unscrew the top section of the clearomizer
  • Pour the e-liquid along the side of the tank
  • Avoid pouring liquid into the central tube
  • Carefully close the top section

When installing a new coil, it is recommended to wait several minutes after filling to allow the cotton to become properly saturated.


🌀 Adjustable bottom airflow

The Q16 Pro has an adjustable airflow located at the base of the clearomizer.

The adjustment ring allows you to change the amount of air passing through the coil and therefore the sensation experienced during inhalation.

By reducing the airflow, it is possible to achieve:

  • A tighter MTL draw
  • A more restrictive sensation
  • More limited vapor production

A larger opening instead provides a looser and slightly airier MTL draw.

However, the Q16 Pro is primarily designed for indirect inhalation, not a very airy direct-to-lung vape.


🔥 1.6Ω JUSTFOG 14 Series coil

The kit includes a 1.6Ω JUSTFOG 14 Series coil.

This low-power OCC coil is particularly well suited to MTL vaping with moderate vapor production.

It particularly emphasizes:

  • A tight draw
  • Reduced e-liquid consumption
  • Low battery load
  • Relatively smooth vaping
  • Low-power use

With this coil, the Q16 Pro's four voltage levels allow you to gradually vary the intensity without having to precisely adjust the wattage.


🔄 Compatible with JUSTFOG Cotton Coil coils

The Q16 Pro works with coils from JUSTFOG's Cotton Coil / 14 Series range.

The manufacturer notably offers two values:

  • 1.2Ω: more dynamic MTL draw
  • 1.6Ω: low-power MTL draw

The 1.6Ω coil is the one that usually comes with the Q16 Pro kit.

Each coil must be used within a suitable voltage range to preserve the cotton and prevent excessive heating.


🛠️ Easily replaceable coil

When the coil reaches the end of its life, there is no need to replace the entire clearomizer.

To change the coil:

  • Remove the clearomizer from the battery
  • Unscrew the tank base
  • Remove the used coil
  • Install a compatible JUSTFOG coil
  • Close the clearomizer properly
  • Fill the tank if necessary

With a new coil, let the cotton absorb the e-liquid for a few minutes before you start vaping.


🔘 Activation with the Fire button

The Q16 Pro operates with a Fire button located on the front of the battery.

Simply hold this button while inhaling to activate the coil.

A second, smaller button allows you to change the voltage level.

This setup remains very simple to use:

  • Turn on the battery
  • Choose the voltage level
  • Adjust the airflow
  • Hold the Fire button
  • Inhale

The Q16 Pro therefore does not have automatic draw activation.


🔗 510 connection

The Q16 Pro clearomizer and its battery use a 510 connection.

The clearomizer can therefore be removed from the battery for cleaning, coil replacement, or maintenance.

This design differs from the proprietary pod systems found on many recent pods.

If another clearomizer is used on the battery, the Q16 Pro's dimensions, resistance, and electrical limits must naturally be respected.


🌿 Which e-liquid should you use with the Q16 Pro?

The Q16 Pro and its 1.6Ω coil are primarily intended for relatively thin e-liquids used for MTL vaping.

A ratio of around 50/50 PG/VG is generally an excellent choice.

This type of device can notably be used with:

  • Classic e-liquids
  • E-liquids intended for indirect inhalation
  • Nicotine salts
  • E-liquids with a balanced PG/VG ratio

High-resistance coils such as the 1.6Ω coil operate at low power and produce a more moderate amount of vapor, making them particularly suitable for MTL.

E-liquids with a very high VG ratio are more viscous and generally less suitable for small coils of this type.


🛡️ Built-in electronic protections

The Q16 Pro battery incorporates several electronic features designed to make its operation safer.

It notably features protection against certain abnormal situations, such as:

  • Short circuits
  • Overcharging
  • Overheating
  • Insufficient battery voltage

These protections do not replace the need to follow JUSTFOG's charging and usage recommendations.
