The VOOPOO Drag H40 Pro and the VooPoo DRAG S2 sit close together on paper, sharing the same general design approach but splitting on power and charging speed. Both are internal-battery devices with a display screen, adjustable airflow, and variable wattage.
This comparison sticks to the specs provided and the categories they fall into: battery, performance, and convenience. Where the data does not clearly favor one device, that is stated rather than guessed at.

Battery
Battery capacity is close, at 2450 mAh for the VOOPOO Drag H40 Pro versus 2500 mAh for the VooPoo DRAG S2, a gap small enough to call a tie. Both use an internal battery and share the same 45-minute charge time to 80%, so this category does not separate the two devices.
Performance
The VooPoo DRAG S2 wins performance on the strength of its 60 W max output compared to 40 W on the VOOPOO Drag H40 Pro, giving it a wider power ceiling for users who want more vapor or want to run lower-resistance coils harder. The DRAG S2’s coil resistance range of 0.1-3.0 Ω also extends lower than the Drag H40 Pro’s 0.3-3.0 Ω, though this specific spec was marked as no comparable data rather than factored into the category call. The higher wattage ceiling is the deciding factor here.
Convenience
Convenience comes out as a tie overall, but the individual specs pull in different directions. The VooPoo DRAG S2 charges faster in practice thanks to its 5 A charge current versus 2 A on the VOOPOO Drag H40 Pro, which matters given they share the same 45-minute charge target. On the other hand, the VOOPOO Drag H40 Pro is lighter at 120 g against 141 g for the DRAG S2, which counts toward pocket comfort and everyday carry. Display, airflow adjustment, and variable wattage are shared features on both devices, and charging port and build material are listed without a clear winner.
The VOOPOO Drag H40 Pro suits buyers who prioritize a lighter device at 120 g and don't need more than 40 W of output.
The VooPoo DRAG S2 suits buyers who want a higher 60 W power ceiling and faster 5 A charging, and don't mind the extra weight.
The verdict
Neither device comes out ahead across the board, and the facts do not support naming a single overall winner. The VooPoo DRAG S2 pulls ahead on performance thanks to its higher max output and faster charge current, while the VOOPOO Drag H40 Pro holds an edge in convenience through its lighter weight. Battery capacity and charge time are effectively tied. Which one makes more sense depends on whether raw output and charge speed matter more to you than a lighter, more pocketable device.
