Introducing the dotMod dotAIO Replacement Tank V4

The V4 brings four meaningful upgrades to the standard dotAIO tank: a redesigned adjustable airflow base, a 4ml e-liquid capacity, an updated anti-leak sealing system and a precision-engineered vortex inner chimney that channels vapour for cleaner, more consistent flavour.

Airflow adjusts from a tight MTL draw to a more open RDL pull. MTL, or mouth-to-lung, is the close, restricted inhale that mirrors drawing on a cigarette. RDL, restricted direct-lung, is a looser, airier style that produces fuller vapour. The V4 covers both without requiring any tools or additional parts.

Compatibility is straightforward. The V4 fits every dotAIO device ever released and accepts the full DotCoil range, so there is no need to change your existing coil preference when you upgrade your tank.

Why Choose the dotMod dotAIO Replacement Tank V4?

• Device type: Replacement boro-style tank for the dotMod dotAIO all-in-one system
• E-liquid capacity: 4ml, reducing how often you need to refill throughout the day
• Airflow: Redesigned adjustable base covering tight MTL to open RDL, adjusted with a simple twist and no tools required
• Leak protection: Updated O-ring and sealing construction keeps the tank dry during travel and everyday use
• Vortex inner chimney: Precision-engineered spiral airflow path smooths vapour delivery and sharpens flavour, regardless of which DotCoil you are running
• Compatibility: Fits all dotAIO device generations and uses the complete DotCoil range
• Colour options: Available in Black, Red, Clear and Royal Blue
• Target vaping style: MTL and RDL (mouth-to-lung to restricted direct-lung)
• Best for: Everyday dotAIO users replacing a worn tank, upgrading from an older V-series design, or adding a second tank in a different colour

The V4's combination of precise airflow control and a practical 4ml capacity makes it one of the most usable everyday tanks in the dotMod range, with no changes required to your existing coils or device setup.

Compatibility and Performance

Compatible coils: The dotMod dotAIO Replacement Tank V4 is designed for the full DotCoil range. The DotCoil adapter base is included in the box, so the tank slots straight into your dotAIO without sourcing additional parts.

Coil resistance and draw style: Tighter MTL draws suit higher-resistance DotCoils. A more open RDL airflow position pairs better with lower-resistance mesh coil options. Check the individual DotCoil product listings to match resistance to your preferred draw style before ordering.

Suitable e-liquids: 50/50 nic salts work well on the MTL setting, delivering a smooth, satisfying hit that suits the lower power outputs typical of the dotAIO system. Higher VG shortfills pair better with a more open airflow position, where the increased airflow supports fuller vapour production. Browse nic salts or explore shortfills to find the right liquid for your draw style.

Using the correct liquid type for your chosen airflow setting also extends coil life and keeps flavour consistent for longer, reducing how frequently you need replacements.

Tank capacity: The V4 holds 4ml of e-liquid. There is no TPD restriction on hardware tank size in the UK, so this is a straightforward practical upgrade over smaller 2ml pod cartridges typically found on standard pod systems.

Output character: The priority here is clean, balanced flavour rather than maximum cloud production. The vortex chimney channels vapour efficiently so flavour notes come through clearly at both ends of the airflow range.

dotMod dotAIO Replacement Tank V4 Highlights

The V4 improves on its predecessors in three key areas: airflow range, liquid capacity and leak resistance. Here is what has actually changed and why it matters for daily use.

• Upgraded adjustable airflow base covering tight MTL to open RDL with a simple twist adjustment
• 4ml e-liquid capacity for fewer interruptions compared to smaller pod cartridges
• Anti-leak construction with updated O-rings and seals, built to hold up during travel and all-day carry
• Vortex inner chimney for smoother, more consistent flavour delivery on every draw
• Full dotAIO compatibility across all device generations, no additional adapters required
• Works with the complete DotCoil range, so your existing coil preference carries over without any adjustment
• Four colour options (Black, Red, Clear, Royal Blue) for matching or contrasting your current dotAIO device

These upgrades are practical rather than cosmetic. The airflow base redesign alone is a meaningful change for vapers who found earlier dot tanks limited in their draw range, and the anti-leak seals address one of the most common frustrations with previous versions.
