The SMOK X-Priv Plus Kit and VOOPOO Drag 6 Box Mod 220W are both box mod kits aimed at sub-ohm vapers, but they differ in how they’re powered and finished. This comparison sticks strictly to the stated specs, flagging where data simply isn’t available for a fair call.
Rather than crown one overall winner, we break things down category by category, since each kit has areas where the other’s documentation falls short.

Performance
On paper, the SMOK X-Priv Plus Kit edges ahead with a max output of 225 W versus the VOOPOO Drag 6 Box Mod 220W’s 220 W. It’s a small numerical gap, but it’s the only performance figure both products have in common, which is why the X-Priv Plus takes this category.
Battery
These two use fundamentally different battery setups — the X-Priv Plus relies on dual 18650 cells with no stated capacity, while the Drag 6 has a built-in 4400 mAh battery. Because one figure is missing and the formats aren’t directly comparable, there isn’t enough evidence to call a winner here.
Convenience
Both kits include a display and offer some form of USB-C charging (labelled Type-C on the X-Priv Plus and USB-C on the Drag 6), putting them on equal footing for day-to-day usability based on what’s stated. This category is a tie.
Capacity
Coil and tank compatibility differs sharply — the X-Priv Plus works with SMOK’s TF-D Sub-ohm Tank and TFV Mini V2 Tank, while the Drag 6 uses VOOPOO’s PnP coil platform plus a universal 510 fit. Without a shared metric like juice capacity or resistance range to compare, there’s insufficient evidence to declare a winner.
Build
The Drag 6 has a stated build of zinc alloy frame with a leather panel, but the X-Priv Plus has no build material listed at all. With only one side of the comparison documented, this category can’t be fairly judged either way.
The SMOK X-Priv Plus Kit suits vapers who want the highest stated wattage and a clearly documented set of safety protections.
The VOOPOO Drag 6 Box Mod 220W suits vapers who prefer a built-in battery with a stated capacity and a documented zinc alloy and leather build.
The verdict
Neither kit comes out on top across the board. The SMOK X-Priv Plus Kit has the edge in raw output and lists a detailed set of safety protections that the Drag 6’s documentation doesn’t mention, while the VOOPOO Drag 6 Box Mod 220W stands out for its stated battery capacity and build materials. Convenience is a genuine tie, and battery, capacity and build simply lack enough matching data to call. Choosing between them comes down to which specifics — replaceable batteries versus built-in capacity, or SMOK’s tank ecosystem versus VOOPOO’s PnP platform — matter more to you.
