The Voopoo Drag 4 followed the Drag 3 as the brand's flagship dual battery mod, yet the two look similar on paper, so what actually changed? The Drag 4 upgrades the Drag 3 with the newer GENE.TT 2.0 chip for faster firing and balanced dual battery management, swaps to the PnP coil UFORCE-L tank, then adds a physical multifunction lock switch and easier battery access, while both share the same 5 to 177W dual 18650 power. Here is the full comparison.

For the bigger picture, our guide on what the Voopoo Drag is covers the range. Our guide on the best Voopoo kit for clouds shows where these mods fit.

What they have in common

Before the differences, it is worth noting how much the Drag 3 and Drag 4 share, since both are excellent dual battery sub ohm mods. Both run on two replaceable 18650 batteries, both fire across the same 5 to 177W range, with both offering Smart, RBA and temperature control modes for flexible vaping. Both are built to the premium standard the Drag name demands, with quality materials and a solid feel in the hand, plus both support fast USB-C charging. If you already own and like a Drag 3, the Drag 4 will feel very familiar, since the core vaping experience is broadly the same. The changes are refinements rather than a reinvention.

The chip upgrade

The most significant change is the chipset. The Drag 3 uses the GENE.Fan 2.0 chip, while the Drag 4 moves to the newer GENE.TT 2.0, Voopoo's more advanced processor at the time of its launch. In practice this brings a faster ramp up, so the device fires even more quickly when you press the button, along with improved dual battery management that balances the charge across both cells individually for more stable, consistent output and healthier batteries. The Drag 4 also refines the temperature control mode to better identify common coil materials. None of this transforms the vape, though it does make the Drag 4 feel that bit sharper and more polished.

The tank and coil change

The other big difference is the tank that comes in the kit. The Drag 3 ships with the TPP tank, which uses Voopoo's TPP coils, while the Drag 4 comes with the UFORCE-L tank that uses the hugely popular PnP coil range, including the newer TW series coils designed for purer flavour, thicker clouds and a longer life. Since the PnP platform is shared across so many Voopoo devices, the Drag 4's tank choice makes its coils easier to find and cross compatible with other kits. If you already have a stock of PnP coils, the Drag 4 fits straight into your setup, which is a practical plus.

Design and handling

Both mods carry the premium Drag look, though there are tweaks. The Drag 4 introduces a redesigned battery compartment with a C-frame for easier access when swapping cells, plus a new physical multifunction lock switch you can set to different jobs, which is handy for safely carrying the device in a pocket. The menu and screen layout were also refreshed. The Drag 3 leans on a leather wrapped design, while the Drag 4 mixes in walnut and resin finishes for a slightly different aesthetic. Neither is clearly better looking, it comes down to taste, though the Drag 4's handling refinements are a small step forward.

Which should you choose?

If you are buying new, the Drag 4 is the more sensible pick, since it has the newer chip, the more widely supported PnP coil tank and the handling refinements, usually at a similar price. If you already own a Drag 3 and are happy with it, there is little need to upgrade, as the core 177W dual battery experience is much the same and your existing TPP setup still performs well. The decision really comes down to whether you value the PnP coil compatibility and the newer chip enough to switch. For most new buyers, the Drag 4 is the natural choice, with our guide on the Drag X vs Drag S covering the compact pod mods if you want something smaller.

The bottom line

The Drag 4 is an evolution of the Drag 3 rather than a revolution. Both are capable 5 to 177W dual 18650 sub ohm mods with Smart, RBA and TC modes, yet the Drag 4 adds the faster GENE.TT 2.0 chip with balanced battery management, swaps to the PnP coil UFORCE-L tank for easier coil compatibility, then brings handling tweaks like a lock switch and better battery access. If you are choosing today, the Drag 4 is the better buy, while existing Drag 3 owners have little reason to rush an upgrade.
