Innokin Coolfire Z80 Zenith II Vape Kit

The Innokin Coolfire Z80 Zenith II Vape Kit is a refined, high-performance setup designed for vapers who value control, consistency, and flavour accuracy. Combining the robust Coolfire Z80 mod with the upgraded Zenith II tank, this kit delivers a highly adaptable vaping platform suited to both mouth-to-lung (MTL) and restricted direct-lung (RDL) styles.

At the heart of the Z80 is Innokin’s advanced FØ technology, engineered to regulate coil frequency rather than simply power output. This intelligent approach significantly improves flavour stability while extending coil lifespan, making the Z80 a practical choice for daily use without compromising performance. With adjustable wattage up to 80W, ultra-fast firing speed, and full compatibility with the acclaimed Z-coil range, this kit offers genuine versatility in a compact, premium build.

Coolfire Z80 Mod Overview

Intelligent Power with FØ Technology

The Coolfire Z80 operates between 6W and 80W, powered by a single external 18650 battery (sold separately). Its defining feature is Innokin’s FØ technology, which alternates current delivery to reduce coil stress and improve e-liquid saturation. The result is a more consistent vape with enhanced flavour clarity and noticeably longer coil life.

An additional Refresh function runs the coil at 40 percent of your set wattage, actively drawing fresh e-liquid into the wick. This helps revive flavour during use and further supports coil longevity.

Durable Design with Refined Ergonomics

Built from a zinc-alloy chassis, the Z80 feels solid without being bulky. The textured grip panels, inspired by suede and leather finishes, provide comfort and control while giving the device a premium aesthetic. A clear colour display presents all key information at a glance, including wattage, battery level, resistance, and mode selection.

Battery access is via a threaded base cap, allowing quick swaps, while USB-C charging provides reliable on-device charging when required.

Zenith II Tank Performance

Precision Airflow for MTL and RDL

The Zenith II tank builds on the legacy of the original Zenith by expanding airflow control to support both tight MTL draws and a smoother RDL inhale. The adjustable airflow ring allows fine tuning, making it suitable for a wide range of vaping preferences without excess noise or turbulence.

Clean Top Filling and Leak Control

Refilling is handled via a rotating top cap with a sealed silicone fill port, reducing the risk of leakage and making top-ups quick and controlled. The 2ml capacity keeps the tank compliant while remaining practical for everyday use.

Z-Coil Compatibility and Flavour Control

The Zenith II tank is fully compatible with the Innokin Z-coil series, developed in collaboration with Phil Busardo and Dimitris Agrafiotis. These coils are widely regarded for their reliability, flavour consistency, and broad resistance range.

Included with the kit are:

• 0.8Ω Z-coil for smooth, flavour-focused MTL vaping

• 0.3Ω Z-coil for warmer RDL performance

This flexibility allows the Z80 kit to adapt easily as your preferences evolve.
