The Innokin Coolfire Z80 Nex and SMOK Vape Pen V2 sit at different points in the market, with different battery setups and control layouts. This comparison sticks strictly to the specs and notes available for each device.
Rather than naming one overall winner, we’ve broken things down by category, since some areas simply don’t have enough comparable data to call fairly.

Performance
The Innokin Coolfire Z80 Nex wins on performance, with a maximum output of 80 W against the SMOK Vape Pen V2’s 60 W. A higher wattage ceiling gives the Coolfire Z80 Nex more headroom for coils that need extra power, which is the deciding factor here.
Battery
Battery is inconclusive: the Innokin Coolfire Z80 Nex uses a replaceable 18650 with no stated capacity, while the SMOK Vape Pen V2 has a fixed internal 1600 mAh cell. Because one figure is missing and the two systems work differently (swappable vs built-in), there isn’t enough comparable data to call a winner.
Convenience
The Innokin Coolfire Z80 Nex takes convenience thanks to its display, which the SMOK Vape Pen V2 lacks. Having a screen means the user can see settings and status at a glance, which the Vape Pen V2 simply doesn’t offer.
Capacity
Capacity can’t be fairly judged: the Innokin Coolfire Z80 Nex’s battery capacity is not stated, so there’s nothing to set against the SMOK Vape Pen V2’s 1600 mAh figure. Without a matching number for both devices, no winner can be determined.
Build
Build materials differ in description rather than comparable quality: the Innokin Coolfire Z80 Nex is listed as zinc alloy, PCTG and leather, while the SMOK Vape Pen V2 is described simply as a metal barrel. These aren’t directly comparable specs, so this category is too thin to call.
The Innokin Coolfire Z80 Nex suits vapers who want higher wattage headroom and an on-device display to monitor their settings.
The SMOK Vape Pen V2 suits vapers who prefer a simple device with a fixed internal 1600 mAh battery and don't need a screen.
The verdict
Neither device comes out as an outright winner. The Innokin Coolfire Z80 Nex has the edge in performance and convenience, thanks to its higher 80 W ceiling and built-in display, but several categories — battery, capacity and build — lack enough comparable detail to settle either way. Buyers should weigh the confirmed strengths of the Coolfire Z80 Nex against their own priorities, since the SMOK Vape Pen V2’s internal 1600 mAh battery and simpler design may suit different needs even without a category win.
