Uforce-X Tank 2 vs Uforce-X Tank (3.5ml Glass Comparison)
It’s important to note that this 5.5ml bubble glass is NOT compatible with the original Voopoo Uforce-X Tank.
Key Differences:
Uforce-X Tank 2 (This Product):
- 5.5ml larger capacity bubble glass
- Designed for the updated Uforce-X Tank II chassis
- Optimised for PnP X coil platform performance
- Improved airflow system and leak resistance
Uforce-X Tank (Previous Generation):
- 3.5ml smaller bubble glass

PnP X Platform Compatibility & Coil Performance
The Voopoo Uforce-X Tank II is built around the next-generation PnP X coil platform, designed for enhanced flavour, longevity, and versatility across DTL, RDL, and restricted airflow vaping styles.
Compatible PnP X Coils:
- PnP X 0.15Ω Coil – High-wattage DTL vaping with maximum vapour production and intense flavour
- PnP X 0.2Ω Coil – Powerful DTL performance with a balance of vapour density and flavour clarity
- PnP X 0.3Ω Coil – Smooth RDL vaping with excellent flavour definition and moderate cloud output
- PnP X 0.45Ω Coil – Versatile RDL option, ideal for slightly restricted airflow and efficient e-liquid use
- PnP X 0.6Ω Coil – Loose MTL / restricted RDL vaping with enhanced flavour and reduced power requirements
- PnP X 0.8Ω Coil – True MTL vaping with tighter draw and improved nicotine satisfaction (ideal for nic salts)
- PnP X 1.0Ω Coil – Tight MTL inhale with lower wattage, optimised for high-nicotine and smooth throat hit
Key PnP X Benefits:
- Up to 100ml e-liquid lifespan per coil (significantly longer than standard coils)
- Enhanced flavour consistency over time
- Improved leak resistance and cotton saturation
- Designed for both mod tanks and pod mod devices
The increased 5.5ml capacity of this bubble glass pairs perfectly with the long-lasting PnP X coils, allowing you to fully benefit from extended coil life without constant refilling.
