VOOPOO UForce-X Sub-Ohm Tank

The VOOPOO UForce-X is a 510-threaded sub-ohm tank built around the PnP X coil platform. It holds 2ml in the UK TPD version, fills from the top via a sliding cap, and accepts the full PnP X coil range to cover MTL, RDL and DTL vaping from one tank. The standout feature is the dual top-inlet airflow design, which routes air from the top of the tank downward through the coil, improving atomisation and keeping the 510 base dry.

Constructed from stainless steel and glass, the UForce-X suits experienced sub-ohm vapers who already use PnP X coils in a pod kit and want to run the same coils in a dedicated tank setup.

• Press-fit coil installation
• 510 threaded base, 810 drip tip

2ml Capacity

The UK TPD version of the UForce-X holds 2ml of e-liquid using the included straight glass tube. The non-TPD version holds 5.5ml with a bubble glass, but this variant is not sold in the UK. The 2ml capacity suits regular top-ups during a vaping session rather than extended use between fills.

Sliding Top-Fill

To fill the UForce-X, slide the top cap sideways to expose the silicone-sealed fill port. The silicone plug retracts when a bottle nozzle is pressed in and reseals automatically when removed. The cap then slides back into place before vaping. This method keeps e-liquid away from the coil seat and the 510 pin.

Dual Top Air Inlets

The UForce-X uses two wide air inlets at the top of the tank rather than at the base. Air travels from top to bottom through the coil, which keeps un-vaporised e-liquid and condensate contained inside the tank rather than settling near the 510 connection. This design also means performance stays consistent as the e-liquid level drops, since there is no exposed bottom airflow slot to pull in dry air.

Stepless Airflow Adjustment

The airflow ring turns continuously without fixed detents, so there is no jump between settings. This makes it straightforward to find the exact draw resistance to suit the coil installed, from wide-open DTL to a more restricted RDL draw. The ring sits just below the drip tip and can be adjusted one-handed. It also forms part of the seal between the fill chamber and the airflow path.

4-Layer Anti-Leak Construction

VOOPOO's four-layer sealing system covers the fill port, airflow ring, coil seat and base. The top-to-bottom airflow path reinforces leak resistance by directing condensate away from the 510 connection. The silicone fill port reseals automatically after each refill. VOOPOO claims the tank can handle 100ml of e-liquid without leaking.

PnP X Coil Compatibility

The UForce-X accepts the full VOOPOO PnP X coil range, covering MTL through to high-wattage DTL:

• PnP-X1 (0.15Ω): DTL, 60-80W
• PnP-X2 (0.2Ω): DTL, 40-60W — included in box
• PnP-X3 (0.3Ω): RDL, 25-40W
• PnP-X4 (0.6Ω): RDL, 20-30W
• PnP-X5 (0.8Ω): RDL/MTL, 15-25W
• PnP-X6 (1.0Ω): MTL, 12-18W

PnP X coils are not interchangeable with the original PnP coil range. Replacement coils are available separately on the VOOPOO PnP X coils page.

Press-Fit Coil Installation

Coils are installed and removed without threading. Pull the spent coil straight out from the base of the tank and push the replacement in until it seats. Prime the new coil with a few drops of e-liquid before filling the tank and allow five minutes to soak before vaping.

510 Threaded Base and 810 Drip Tip

The UForce-X connects to any regulated mod with a standard 510 thread. The 28.4mm diameter means it will overhang slightly on most single-18650 mods but sits flush on dual-battery and larger single-battery devices. The 810 drip tip is compatible with aftermarket 810 tips if a different bore or material is preferred.
