The VOOPOO Drag H40 Pro and VooPoo Drag S3 sit close together in VooPoo’s lineup, but they make different tradeoffs around battery capacity, output, and charging speed. Both share a similar feature set on paper, so the differences that matter come down to a handful of specs.
This comparison sticks to the numbers provided for each device, calling out where one pulls ahead and where there simply isn’t enough data to declare a winner.

Battery
The VOOPOO Drag H40 Pro wins the Battery category, and the charge time figures explain why: it reaches 80% in 45 minutes against 90 minutes for the VooPoo Drag S3, despite both devices charging at the same 2 A current. The VooPoo Drag S3 does carry a larger 3000 mAh cell versus 2450 mAh on the VOOPOO Drag H40 Pro, which is why capacity itself is called a tie rather than a win for either side — more capacity on the Drag S3 is offset by its slower charge time, while the H40 Pro’s smaller battery fills up much faster. Battery type is listed as internal for the H40 Pro and built-in, non-removable for the Drag S3, wording that describes the same basic setup without giving comparable detail, so that line isn’t scored.
Performance
The VooPoo Drag S3 takes Performance on the strength of its max output, 60 W versus 40 W for the VOOPOO Drag H40 Pro. That higher ceiling gives the Drag S3 more headroom for coils built to run hotter, though the facts don’t include throughput or flavor-quality data beyond the wattage figures themselves. Coil resistance ranges differ too — 0.3–3.0 Ω on the H40 Pro versus 0.15Ω to 1.0Ω on the Drag S3 — but without matching units of comparison or performance context, that spec is marked as not comparable rather than a factor in the category result.
Convenience
Convenience comes out a tie. Both devices include a display screen, adjustable airflow, and variable wattage, and both charge over Type-C. Weight is only stated for the VOOPOO Drag H40 Pro at 120 g, with no figure given for the VooPoo Drag S3, so body weight can’t be weighed against it. Build materials are described in slightly different language for each — zinc alloy plus leather for the H40 Pro, zinc alloy with a leather texture for the Drag S3 — which reads as materially similar but isn’t presented as directly comparable data.
The VOOPOO Drag H40 Pro suits vapers who want to get back to a usable charge quickly, given its 45-minute time to 80%.
The VooPoo Drag S3 suits vapers who want more power on tap, given its 60 W max output compared to 40 W on the H40 Pro.
The verdict
Neither device claims every category, and the facts don’t support naming one overall winner. The VOOPOO Drag H40 Pro’s advantage is a faster charge to 80%, while the VooPoo Drag S3’s advantage is a higher max output; convenience features land even between them. Which one fits better depends on whether quick top-ups or higher wattage headroom matters more to the person using it.
