The mack daddy. The boss. The lord of the mesh. Call it what you want but Freemax really knows what it is doing when it comes to sub-ohm vape tanks.

I loved the OG Fireluke tank and its successor models were brilliant too.

But the Freemax Fireluke 4 is kind of in a different league. It looks stunning, for starters, the coil options for it are insane, and the flavor and clouds are some of the best I’ve ever seen on a tank (this is why it currently ranked #1 inside our Best Vape Tank guide).

Can you tell I like it? Read on to find out why…

Design and Build Quality

Aesthetic and Material

I must say that I find the Freemax Fireluke 4 Tank to be very appealing with a modern design. Its glass tube and stainless steel construction provide an elegant look, ensuring that the tank matches nicely with virtually any vape mod.

The Fireluke 4 Tank comes in various colors such as black, silver, and blue, allowing you to choose the one that suits your style – or your vape mod – the best. With a diameter of 28mm, the Fireluke 4 is a decent sized tank but it isn’t unwieldy.

I’ve run on a bunch of vape mods, both single and dual-18650, and it sits pretty on all of them. Beyond this, the machining and overall finish of the tank is brilliant. It looks and feels super premium which is exactly what you want from a sub-ohm tank.

Durability and Features

The Freemax Fireluke 4 Tank is built to last, with its durable stainless steel material and a sturdy glass tube, I haven’t experienced any leaks or cracks so far (and I’ve dropped it a fair few times).

The tank is ISO 8317 Child Resistant Certified, which helps to prevent unintended access by children. It also comes with a 510 thread connection and an 810 drip tip, making it compatible with 99.9% of vape mods.

I have two small kids and, despite my best efforts, they do occasionally grab hold of my vape and mod. I have settings in place so it never fires. But the fact that the tank itself is child-proof is a massive bonus that I didn’t even know I needed in my life!

Additionally, the tank weighs only 59g, so it doesn’t add too much heft to my already fairly hefty vape mod which is always a good thing, especially if – like me – you’re more used to pod vapes these days.


Here are some notable specifications of the Fireluke 4 Tank:

  • Material: Stainless Steel & Glass
  • Thread: 510
  • Diameter: 28mm
  • Drip Tip: 810
  • Weight: 59g
  • Colors: Black, Silver, Blue


The design and build quality of the Freemax Fireluke 4 Tank is remarkable. Its aesthetic and material lend itself to a luxurious look and feel, while the durability and features make it a reliable option for me to enjoy my vaping sessions.

Flavor, Coils & Vapor Production

I found the flavor and vapor production of the Freemax Fireluke 4 quite impressive which is a nice way of saying it has run rings around every single sub ohm tank I’ve tested in 2023.

The flavor is uniformly impressive, regardless of the coil you opt for, and this is part and parcel of why Freemax is so well respected: its coils are just next-level good.

The FM COILTECH5.0 offers a 50% improvement on flavors and heating speed over its predecessor (what you found in the Fireluke 3).

The tank works well, especially with the X Mesh Coils, TX Mesh Coils, and 904L X Mesh Coils. These coils are designed to enhance both the taste and vapor output.

I noticed that the Freemax Fireluke 4 performance can cater to a wide range of vaping styles, making it a suitable choice for vapers that like to switch things up on the regular. The available coils include the 0.15ohm FL1-D coils and 0.2ohm FL mesh coils.

Airflow and Draw

The adjustable airflow control of the Freemax Fireluke 4 allows me to customize my vape experience. And while tweaking the airflow control, it’s easy to find the right balance between flavor intensity and vapor production.

Coil Longevity

Despite their excellent performance, these coils also have an impressive longevity. With proper care, the Freemax mesh coils can last for several weeks and still deliver consistent flavor and vapor.

The mesh coil options make it possible to match your vaping preferences with durable coil choices.

What sets Freemax coils apart is the use of a mix of tea fiber cotton formula. This formula improves the wicking efficiency, which ensures richer flavors and prolonged coil lifespan.

Plus, the variety of coil options allows you to personalize your vaping experience, as well as providing a dependable, long-lasting product.

Ease of Use

Filling and Maintenance

With a sliding top fill system, I found the process quick and mess-free. To refill the tank, all you have to do is slide the top cap to reveal the fill port. Additionally, the package includes a replacement glass and an extra silicone ring, which can be helpful for dealing with accidents or wear over time.

As for maintenance and cleaning, the Freemax Fireluke 4 has a detachable structure which, if the mood takes you, allows you to complete take it apart and clean it within an inch of its life. I seldom do this but the option to do so is there if you’re the type that does that kind of thing.

Priming and Coil Replacement

The Freemax Fireluke 4 utilizes threaded coil installation which makes installing and removing coils a cinch. It comes with two coil options in the box – 0.15ohm X1-D coils and 0.2ohm X2 coils – and you can pick up spares here.

It is simple to prime as well. Just install the coil, add some juice and let it sit for 10 to 15 minutes. After you’ve done this, start the wattages nice and low and then work upwards incrementally until you find your sweet spot.

As for the coil’s lifespan, I’ve been getting anywhere between 14 to 20 days from each coil. I’ve been using this tank for a solid 5 months now and its coils – all the variants – are very impressive, lasting considerably longer than my last SMOK sub ohm tank.

Is The Freemax Fireluke 4 Worth It?

Freemax Fireluke 4 Review: Meet 2024's Best Sub-Ohm TankPin

Look. There’s loads of powerful sub-ohm tanks available right now and most of them are pretty good. But for me, the Fireluke 4 is the one to beat right now

Why? It has an insane array of potential coil options, it is backwards compatible with legacy Fireluke coils, it is simple to set-up and live and it never leaks. 

The flavor is, frankly, ridiculous. I’ve probably put about a gallon of vape juice through this thing – loads of different brands and flavors – and it is always consistently brilliant. 

It’ll also chuck clouds with the best of them. Run it at higher wattages and you’ll fog up an entire room with just a few big hits. 

Bottom line? The Freemax Fireluke 4 does a lot of things and, unlike some of its competitors, it does all them very well. 

Everything from the tank’s design to its coils are designed to such a high standard that it is impossible to see why anyone would use anything else? 

This tank has been my daily driver for months now, and I do not see myself getting rid of it anytime soon.
