Description
The FreeMax Fireluke 4 is a 25mm sub-ohm tank (28mm at the widest point of its bubble glass) that holds 5mL of e-liquid, or 2mL in the TPD configuration. It carries a standard 510 connection and an 810 drip tip, and continues FreeMax’s long-running Fireluke line, which built its reputation on dense flavor and cloud production from large-surface mesh coils.
At its core is FreeMax’s FM COILTECH5.0 / Double-D mesh system, built around military-grade SS904L mesh and upgraded tea-fiber cotton for cleaner flavor and faster heat-up than earlier Fireluke generations. The tank ships with a 0.15ohm X1-D mesh coil pre-installed and a spare 0.2ohm 904L X2 mesh coil, and accepts the wider FreeMax X, TX and 904L X mesh coil range, covering roughly 20W to 90W depending on the coil head.
Loading and airflow are kept simple: a sliding top cap exposes a single fill port, and a dual-slotted bottom airflow control ring tunes the draw. It is a straightforward direct-lung setup aimed at sub-ohm vapers who want bold flavor and vapor, and a clean drop-in upgrade for existing Fireluke owners.
