Battery
Battery capacity is close, with the VOOPOO Drag H40 Pro at 2450 mAh and the VooPoo DRAG S2 at 2500 mAh, a gap small enough to call a tie. Charge time to 80% is identical at 45 minutes for both devices. The DRAG S2 does support a higher 5 A charge current versus 2 A on the Drag H40 Pro, but this falls under the Performance and Convenience figures rather than changing the overall battery tie, since capacity and charge time land even.
Performance
The VooPoo DRAG S2 wins on performance thanks to its 60 W max output compared to the Drag H40 Pro’s 40 W, giving it more headroom for higher-wattage vaping. The DRAG S2 also supports a 5 A charge current against the Drag H40 Pro’s 2 A, meaning it can pull power back in faster despite sharing the same 45-minute charge-to-80% figure. Coil resistance ranges differ slightly (0.3–3.0 Ω on the Drag H40 Pro versus 0.1-3.0 Ω on the DRAG S2), but there isn’t enough comparable data to weigh that difference on its own.
Convenience
Convenience comes out as a tie overall. Both devices include a display screen, adjustable airflow, and variable wattage, and both use a Type-C charging port, though the exact port naming differs slightly in the listed specs. The Drag H40 Pro is lighter at 120 g versus 141 g for the DRAG S2, which helps its everyday carry feel, but that weight advantage alone isn’t enough to shift the tied category result.
The VOOPOO Drag H40 Pro suits buyers who prioritize a lighter, more compact device and don't need output beyond 40 W.
The VooPoo DRAG S2 suits buyers who want higher maximum output and faster charge current for more demanding vaping sessions.
The verdict
Neither device comes out as an outright winner across the board. The VooPoo DRAG S2 pulls ahead on performance with its higher 60 W output and faster 5 A charge current, while battery life and general convenience features like the screen, airflow, and wattage controls remain evenly matched between the two. The VOOPOO Drag H40 Pro’s main advantage is its lighter 120 g build, which matters for comfort but doesn’t offset the DRAG S2’s power edge. Choosing between them comes down to whether raw output or a lighter, more compact feel matters more to you.
