Introduction
If you’re into sub-ohm vaping, chances are you’ve heard whispers of the Freemax Fireluke 4. Whether you’re chasing clouds or savoring rich e-liquid flavors, this tank has stirred up serious buzz in the vape community. In this Freemax Fireluke 4 review, we’ll dive into what makes it a contender for one of the best sub-ohm tanks of the year—or not.
Let’s unpack its features, performance, coil technology, and whether it truly deserves the title of flavor beast.
First Impressions: Design and Build Quality
Sleek and Sturdy Aesthetics
At first glance, the Fireluke 4 doesn’t try to reinvent the wheel, but what it does, it does very well. It has a sleek, rounded design with multiple color options—perfect for pairing with modern vape mods. The stainless steel construction gives it a solid feel in hand, while the resin drip tip adds a splash of personality.
Fit and Finish
Freemax’s attention to detail shines here. The top cap has a secure locking system, preventing spills during travel. Threading is smooth, and the glass section feels well-protected. It fits seamlessly onto most mods without any overhang.
Tank Capacity and Filling System
Juice Capacity
Depending on the version you get (standard or TPD), the tank offers a capacity of either 5ml or 2ml. For cloud chasers, the 5ml variant will be the go-to, offering enough juice to last several puffs without constant refills.
Top-Fill Simplicity
The sliding top-fill mechanism is a major convenience. You just push back the cap, and there’s your fill port—clean, quick, and mess-free. The silicone membrane underneath helps prevent leakage while filling.
Coil Compatibility and Technology
FM CoilTech 5.0 Explained
What sets the Fireluke 4 apart is its use of FM COILTECH 5.0, featuring a dual mesh structure with military-grade SS904L mesh and tea fiber cotton. This unique coil design enhances flavor purity and extends coil life.
The tank is compatible with Freemax’s popular X/TX/904L series coils, giving users plenty of choices depending on their vaping preferences.
Coil Performance and Longevity
In testing, the 0.15-ohm X1-D mesh coil performed exceptionally well. Flavor was immediate and vibrant. Cloud production was dense, and there was minimal spitback. Most users report coils lasting between 7–12 days with moderate to heavy use, thanks to the durable stainless mesh and quality cotton.
Flavor Experience: Is It Really a Flavor Beast?
Now for the core of this freemax fireluke 4 review—the flavor.
When paired with premium e-liquids, the Fireluke 4 truly shines. Fruity blends are crisp and accurate, dessert flavors come through creamy and layered, and menthols hit hard without muting subtleties.
The dual mesh coils distribute heat evenly, avoiding hot spots. This results in a warm, flavorful vape with impressive depth. Some vapers argue it rivals the Voopoo TPP-X or even the legendary Falcon King in flavor reproduction.
Airflow and Cloud Production
Adjustable Bottom Airflow
Freemax includes a smooth bottom airflow ring that allows full customization. Wide open, it’s a cloud machine. Partially closed, it turns into a flavor-focused setup with tight, concentrated draws.
Dense Clouds Without Sacrificing Taste
Cloud chasers will love this tank. Even at mid-wattage levels, the vapor is thick and satisfying. Importantly, flavor isn’t sacrificed for clouds—a rare balance in the sub-ohm world.
Leak Resistance and Maintenance
Leak-Free Design
The Fireluke 4 performs admirably in daily use. Even after sitting horizontally in a bag for a few hours, there was no noticeable leaking. The dual O-rings and upgraded cotton wicking do a great job of holding e-liquid where it belongs.
Easy to Clean and Replace Coils
Disassembling the tank for cleaning is straightforward. The glass and coil section can be removed without hassle. Coil replacement is a plug-and-play process, making it ideal for beginners as well.
