Liverpool Zero-nicotine liquids comparison chart (RELX Pro)

Zero-nicotine liquids advice for Liverpool, covering care routine, what to look for and where the trade-offs actually sit.

We spent weeks putting zero-nicotine liquids options through their paces so the recommendations here reflect real use. Comparing this against a 60:40 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume.

We spent weeks putting zero-nicotine liquids options through their paces so the recommendations here reflect real use. Materials are unremarkable on paper and feel reassuringly solid in the hand, with no flex in the body at all.

The Cobalt Blue finish hides fingerprints far better than the gloss options, which matters more than it sounds on a device handled daily. Worth noting that the 510-X takes a small amount of care to keep clean, which we cover in the maintenance section below. For loyal customers, the learning curve is shorter than the specification list suggests, and daily use is straightforward from the first charge.

The instruction booklet is thin, but the diagrams are clear enough that most people set the device up without further help. Flavour tracking stays consistent from the first day to roughly the 1.2 Ω mesh mark before the profile flattens and a swap makes sense. In Liverpool, availability of the 1.2 Ω mesh coil is the practical bottleneck, not the device itself.

Expect roughly 1730 full puffs from a charge at 0 mg/ml, based on average session length in our testing. Delivery across Liverpool is typically two to four working days with tracked dispatch, and returns are straightforward within the standard window. The build quality on IQOS III is a step above most of what sits in the same price bracket, and the finish resists the chipping that usually shows after a few months of pocket carry.

Comparing this against a 60:40 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume. The 5.0 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem. Expect roughly 1730 full puffs from a charge at 0 mg/ml, based on average session length in our testing.

Charging over USB-C takes about 86 from empty, and the pass-through means the device can be used while plugged in on the smaller batteries. Two things to check before ordering: the USB-C socket on the base and whether the 1.2 Ω mesh coil is the newer generation. Battery behaviour is where the IQOS III earns its keep: the 650 mAh cell holds a usable charge for most of a day at 50 and recharges over USB-C.

Vapour production is more than adequate at 50, and pushing beyond that adds heat rather than anything worth carrying. If you take one thing from this page, make it the coil compatibility check. A device that needs a coil you cannot source locally becomes an expensive ornament within a month. The throat hit is noticeably firmer than a 60:40 PG/VG blend, so if you prefer a smoother draw, mix accordingly.

The specification sheet is where the real trade-offs show.

Flavour and performance notes

A representative profile is Melon Cucumber: fresh, light, described as clean cucumber under sweet melon. On a 60:40 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 1.2 Ω mesh mark before the coil begins to mute it.

Practical considerations in Liverpool

Availability in Liverpool is the factor that decides most outcomes here. Confirm the 1.2 Ω mesh and the USB-C are both in stock before committing, and check that the 510-X matches your existing device if you already own hardware. Duty and GBP rates move, so treat prices as current rather than fixed.

Take the time to get it right the first time; the difference shows up over months of use rather than days.
