Justfog Q16 FF Tank Review: 7 Key Specs, Coil and Price (Dubai, 2026)
In this guide
Overview
This Justfog Q16 FF Tank review goes through a compact 510-thread tank with a 1.9ml capacity, a 1.2ohm organic cotton coil, leakproof side filling and adjustable bottom airflow, listed at AED 55 at Vaps Shop AE in Dubai. It comes in black only.
A tank is not a complete vape: it needs a compatible 510 battery or mod to work. This page covers what the catalogue states about size, coil, filling and airflow, so you can judge whether it suits the device you already own.
About this review: specs and prices come from the manufacturer and our Dubai catalogue; we have not independently measured battery life, coil life or vapour output. Last updated: 29 September 2026.
Nicotine is addictive, and vaping products are sold only to adults aged 18 and over under UAE regulations. The UAE’s tobacco provisions are published at u.ae. Our UAE nicotine cap explainer covers the liquid strength rules that apply to whatever you put in a tank.
Justfog Q16 FF Tank Review: Size and Build Specs
The catalogue lists the Q16 FF at 59.4mm by 16mm, with a 16mm base diameter. That makes it a slim, short tank, intended to sit on small mods and battery sticks without overhanging the body. The listing also states a Pyrex glass tube, which lets you see the e-liquid level through the side of the tank, and a black finish.
Dimensions matter more than they seem when you pair a tank with a device. A 16mm tank on a much wider mod will leave a visible step at the join, while a 16mm tank on a slim stick looks flush. The catalogue does not give a weight or a stainless steel grade, so those are left out here. If you are unsure whether it will look right on your device, WhatsApp us the model.
Coil, Resistance and Flavor Focused Technology
The tank is sold with a 1.2ohm organic cotton coil, and the listing names the JUSTFOG Q16 FF coil series as the matching range. The manufacturer describes the design as Flavor Focused Technology. The coil is installed by threading it into the base, so replacing it is a simple screw-in job rather than a swap of a cartridge.
At around 1.2ohm the coil sits between the very restricted resistances used with tiny pod kits and the sub-ohm coils used at high wattage. The catalogue does not state a recommended wattage range, so check the rating printed on the coil pack. Our coil resistance guide explains what resistance numbers mean, and our mesh vs single coil guide covers how coil construction differs.
Capacity and Leakproof Side Filling
Capacity is 1.9ml, which is on the small side for a tank. It suits people who prefer to refill often with a small amount of liquid, and it keeps the tank compact. It is a smaller volume than the 3.5ml to 5.5ml tanks that also sell in our accessories range, so if you want fewer refills, a larger tank is worth a look.
The listing describes a leakproof side-filling system. In general, side-fill tanks have a fill port on the side of the tank so the coil area is not opened up while you pour. The catalogue does not give the port size, so check that your bottle nozzle is a fine tip. As with any tank, leaks can also come from over-filling or from a coil that is not fully seated; our leaking causes and fixes guide covers the common ones.
Adjustable Bottom Airflow and Draw Style
Airflow is adjustable at the bottom of the tank through a control tube, according to the listing. Adjustable airflow lets you open or close the air path to change how easy or tight the draw feels. The catalogue does not say whether the tank is designed for mouth-to-lung or direct-to-lung use, so it is not classified here.
With a 1.2ohm coil and a slim body, a tighter draw is the usual pairing in general terms, but that depends on the device and liquid you pair it with. Our MTL vs DTL explainer sets out the difference so you can decide which style you want before you buy.
510 Thread and Device Compatibility
The connection is 510, the most widely used threaded standard for tanks, atomisers and cartridges. A 510 tank fits any battery or mod with a matching 510 connector. The listing does not name a device list, so compatibility is stated at the connection level only.
Two practical checks before you buy: the diameter and the power output. A 16mm base suits slim devices, and the coil in this tank is a modest resistance, so it is not a sub-ohm tank. Do not pair it with a mod set to a wattage beyond what the coil pack states. Our sub-ohm tank guide explains the difference between the two tank classes and when each applies.
Who This Tank Suits
On the specs, the Q16 FF suits an adult who already owns a slim 510 battery or mod and wants a small refillable tank with side filling and adjustable airflow. It also suits someone who prefers a compact tank they can carry easily and refill in small amounts.
It is a less obvious pick if you want a large e-liquid capacity, a sub-ohm coil or a choice of colours, because the catalogue lists 1.9ml, a 1.2ohm coil and black only. If you are new to refillable devices, our beginner pod kit guide explains the formats, and our hardware and coils guide covers where tanks fit.
Price, Coil Replacement and How to Buy in Dubai
At AED 55 the Q16 FF is priced at the lower end of the tanks in our accessories range. The listing names a 1.2ohm organic cotton coil as part of the specification; ask us whether one is supplied, as the catalogue does not say, and it does not state a rated coil life. Coil life depends on liquid type, power and how often you use the device. Our coil life guide explains the general signs that a coil needs replacing.

Justfog Q16 FF vs VOOPOO TPP Pod 2 Tank
Both cost AED 55. The TPP Pod 2 holds 5.5ml against 1.9ml here, but it uses a magnetic base plus 510 and VOOPOO TPP coils, so it is aimed at specific devices. The Q16 FF is the more compact of the two.
Justfog Q16 FF vs Geekvape Z Nano 2
The Z Nano 2 lists 3.5ml and top filling at AED 120, and states both MTL and DTL support. The Q16 FF is smaller and cheaper, with a coil included and side filling.
Checking coil availability before you buy
Since the tank uses the Q16 FF coil series, confirm that replacement coils are in stock before you commit. WhatsApp us and we can check the range against your order.
Care and cleaning in general terms
Rinse the glass tube and airflow tube with warm water when you change coil, dry them fully and reassemble. This is generic advice and not a claim about this tank in particular.

Verdict
