Zero-nicotine liquids for long-session users: what works (2025) (v2)
Zero-nicotine liquids advice for Liverpool, covering spare parts, what to look for and where the trade-offs actually sit.
The gap between a mid-range and a premium zero-nicotine liquids narrows once you know which components you actually use. Two things to check before ordering: the Micro-USB socket on the base and whether the 0.8 Ω mesh coil is the newer generation.
There is no single best zero-nicotine liquids for everyone in Liverpool, and anyone telling you otherwise is selling something. What surprised us most was how little the 0.8 Ω mesh coil changes the draw character compared with the 60:40 PG/VG liquid sitting in the chamber.
The narrow bore mouthpiece is comfortable over long sessions and resists the condensation that gathers on narrower tips. Comparing this against a 60:40 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume. The 2.0 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem.
Battery behaviour is where the AEKU Slim earns its keep: the 4000 mAh cell holds a usable charge for most of a day at 150 and recharges over Micro-USB. We would pair the AEKU Slim with a 60:40 PG/VG liquid, which is where the balance between throat hit and cloud density sits most comfortably. Replacement coils are widely available, and the 0.8 Ω mesh coil is the sensible default to keep in stock.
The Sunset Orange 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 thread takes a small amount of care to keep clean, which we cover in the maintenance section below. For long-session users, the learning curve is shorter than the specification list suggests, and daily use is straightforward from the first charge.
Vapour production is more than adequate at 150, and pushing beyond that adds heat rather than anything worth carrying. Expect roughly 1784 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.
What surprised us most was how little the 0.8 Ω mesh coil changes the draw character compared with the 60:40 PG/VG liquid sitting in the chamber. Charging over Micro-USB takes about 67 from empty, and the pass-through means the device can be used while plugged in on the smaller batteries. Worth noting that the 510 thread takes a small amount of care to keep clean, which we cover in the maintenance section below.

Flavour and performance notes
A representative profile is Watermelon Chill: sweet, juicy, described as watermelon with a clean cooling exhale. On a 60:40 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 0.8 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 0.8 Ω mesh and the Micro-USB are both in stock before committing, and check that the 510 thread matches your existing device if you already own hardware. Duty and GBP rates move, so treat prices as current rather than fixed.
If any of the above addresses what you were trying to solve, the rest of the pages in this section cover it in more detail.
