The Innokin Coolfire Z80 Nex and the SMOK Vape Pen V2 sit in different corners of the vaping market, with different priorities in output, battery setup, and design. This comparison sticks strictly to the specs and review notes available for each device.
Some categories have a clear winner based on the numbers. Others simply don’t have enough comparable data between the two products to call a winner, and we say so rather than guess.

Performance
The Innokin Coolfire Z80 Nex wins on performance thanks to its 80 W max output compared to the SMOK Vape Pen V2’s 60 W. That extra headroom gives the Coolfire Z80 Nex more flexibility for higher-wattage coil setups, while the Vape Pen V2’s lower ceiling keeps it more limited in this specific measure.
Battery
The two devices use different battery approaches — the Coolfire Z80 Nex takes a replaceable 18650 cell with no stated capacity, while the Vape Pen V2 has a fixed internal battery rated at 1600 mAh. Because one is removable with an unstated capacity and the other is fixed with a known capacity, there isn’t a fair like-for-like way to compare them, so this category is insufficient evidence.
Convenience
The Innokin Coolfire Z80 Nex wins on convenience due to its built-in display, which the SMOK Vape Pen V2 lacks entirely. A display gives the user direct feedback on settings and status, an everyday usability feature the Vape Pen V2 simply doesn’t offer.
Capacity
Capacity-related specs, including tank and coil compatibility, aren’t structured in a directly comparable way between the two devices — the Coolfire Z80 Nex supports its own Z Coil series while the Vape Pen V2 lists specific coil resistances (0.6ohm DC, 0.3ohm dual, 0.15ohm Strip). Without matching figures, this category is insufficient evidence.
Build
Build materials differ in kind rather than in any measurable way: the Coolfire Z80 Nex uses zinc alloy, PCTG, and leather, while the Vape Pen V2 uses a metal barrel. Neither description gives a comparable metric like weight or durability rating, so this category is insufficient evidence.
The Innokin Coolfire Z80 Nex suits users who want higher maximum output and an onboard display for tracking settings.
The SMOK Vape Pen V2 suits users who want a simpler internal-battery device with a stated capacity and multiple coil resistance options for direct-to-lung vaping.
The verdict
Neither device comes out as an outright winner across the board. The Innokin Coolfire Z80 Nex takes the Performance and Convenience categories on the strength of its higher 80 W output and built-in display, while Battery, Capacity, and Build don’t have enough matching data points to declare a winner either way. Choosing between them depends on which of these specific, documented differences matters more to the individual user.
