Innokin Coolfire Z Air Pod Kit 18W Review: Specs, Price and Who It Suits
The Innokin Coolfire Z Air Pod Kit 18W is a budget-friendly, refillable pod system aimed at vapers who want a no-fuss, pocketable device rather than a feature-packed mod. Currently listed at £16.99 at Vapesourcing.uk via our Innokin Coolfire Z Air Pod Kit 18W deal page, it sits at the entry-level end of Innokin’s pod range. This review looks purely at the published specifications and pricing, as nobody at VapeBargains has handled or tested this unit.
What it is
The Coolfire Z Air is an 18W pod-based kit designed for mouth-to-lung (MTL) vaping. It uses refillable or compatible replacement pod cartridges rather than prefilled or disposable pods, meaning you top it up yourself with your own choice of e-liquid or nic salt. UK law caps nicotine e-liquid at 20mg/ml strength and 10ml bottle size, and pod or tank capacity at 2ml, so any compatible pods and e-liquids you pair this with will already sit within those limits. As a reminder, single-use disposable vapes have been illegal to sell or supply in the UK since 1 June 2025, so this kind of refillable, low-power pod kit is a legitimate and sensible alternative for anyone still looking for a simple device.
The kit ships with the Coolfire Z Air mod itself and at least one pod cartridge. Exact pod capacity and coil resistance are not stated in the information available, so we won’t speculate on those figures here.

Who it suits and who it does not
On paper, this kit suits adult vapers who want straightforward, plug-and-play operation without coil-building or complicated settings. The 18W ceiling makes it a natural match for nic salt e-liquids, which are designed to deliver nicotine satisfaction efficiently at lower wattages, and it suits anyone prioritising a tight, cigarette-like MTL draw over big vapour. It’s also a sensible pick as a secondary, grab-and-go device for existing vapers who want a compact backup for work, travel or days when carrying a full-size mod isn’t practical.
It is unlikely to suit vapers who want sub-ohm, direct-lung vaping or large vapour production, since 18W is well below the 40–100W range typical of sub-ohm tanks. Anyone wanting adjustable airflow, variable wattage control, or detailed display information should also look elsewhere, as none of these are mentioned as features here. Given the limited published detail on battery life and pod capacity, those who want precise runtime figures before buying may want to weigh that uncertainty against the low price.
How it compares on paper
Within Innokin’s own range on our site, there are a few relevant comparisons. The Innokin Zenith Nex Tank at £9.29 is a tank rather than a pod system, and likely to appeal more to those wanting a traditional refillable sub-ohm or MTL tank setup with a wider range of coil options, rather than the fixed-pod simplicity of the Coolfire Z Air.
More directly comparable is another listing of the same Innokin Coolfire Z Air Pod Kit 18W at £16.49, which is marginally cheaper than the £16.99 deal featured here — worth a glance if price is your only deciding factor, though the specification is identical since it’s the same device.
Stepping up, the Innokin Coolfire PZPulse Pod Vape Kit at £19.99 costs a little more and is likely to appeal to those wanting a more feature-rich pod kit from the same manufacturer, if the Coolfire Z Air’s stripped-back approach feels too basic.
Compared against sub-ohm tank systems generally, the Coolfire Z Air’s lower 18W output trades vapour volume and e-liquid throughput for simplicity, lower running costs, and longer battery life between charges — a sensible trade-off for its intended MTL, nic-salt-focused audience.
Price and value
At £16.99 via our Innokin Coolfire Z Air Pod Kit 18W deal page, this sits comfortably in budget territory for a named-brand pod kit. Because it’s refillable rather than disposable, ongoing costs come down to replacement pods and whatever e-liquid you choose, rather than buying a new device each time. Worth noting: the Vaping Products Duty takes effect from today, 1 October 2026, at a flat £2.20 per 10ml of e-liquid. This duty applies to the e-liquid you buy to use in the device, not to the kit itself, but it’s a sensible factor to budget for alongside the £16.99 hardware cost when working out your overall running costs going forward.
Innokin’s general reputation for reliable build quality adds some reassurance at this price point, even without hands-on verification, since you’re buying into an established platform rather than an unknown budget brand.
Verdict on paper
Based purely on its specifications and price, the Innokin Coolfire Z Air Pod Kit 18W looks like a sensible, low-risk pick for beginners wanting a simple MTL pod kit, or for existing vapers after an affordable secondary device. Its refillable design and nic salt compatibility keep running costs manageable, and the £16.99 price makes it an easy, low-commitment entry point. Those wanting detailed battery specs, adjustable features, or higher-power direct-lung vaping should look elsewhere in the range, but as a straightforward grab-and-go pod kit, it ticks the basic boxes on paper.
