Nicotine liquids upgrades and spare parts (800 mAh)
Nicotine liquids advice for Liverpool, covering battery life, what to look for and where the trade-offs actually sit.
Local availability in Liverpool shapes the practical answer more than the marketing does. Comparing this against a 80:20 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume.
Local availability in Liverpool shapes the practical answer more than the marketing does. In Liverpool, availability of the 1.4 Ω mesh coil is the practical bottleneck, not the device itself.
The build quality on RELX Pro 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. Build quality is the quiet differentiator here, with tight seams and a connector that has not loosened after repeated removal. Charging over Type-C fast charge takes about 38 from empty, and the pass-through means the device can be used while plugged in on the smaller batteries.
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 80:20 PG/VG blend, so if you prefer a smoother draw, mix accordingly. Pricing in Liverpool shifts with import duty, so the figures here reflect current GBP rates rather than a fixed list price.
Replacement coils are widely available, and the 1.4 Ω mesh coil is the sensible default to keep in stock. The included spare coils are useful for the first fortnight, after which you will be ordering your own. Airflow control on the RELX Pro is adjustable enough to move from a warm, restrained draw to something far more open without removing the tank.
We would pair the RELX Pro with a 80:20 PG/VG liquid, which is where the balance between throat hit and cloud density sits most comfortably. Delivery across Liverpool is typically two to four working days with tracked dispatch, and returns are straightforward within the standard window. Pricing in Liverpool shifts with import duty, so the figures here reflect current GBP rates rather than a fixed list price.
Two things to check before ordering: the Type-C fast charge socket on the base and whether the 1.4 Ω mesh coil is the newer generation. Battery behaviour is where the RELX Pro earns its keep: the 650 mAh cell holds a usable charge for most of a day at 40 and recharges over Type-C fast charge. We would pair the RELX Pro with a 80:20 PG/VG liquid, which is where the balance between throat hit and cloud density sits most comfortably.
The Rose Quartz finish hides fingerprints far better than the gloss options, which matters more than it sounds on a device handled daily. Worth noting that the Q-Plus takes a small amount of care to keep clean, which we cover in the maintenance section below. For budget shoppers, the learning curve is shorter than the specification list suggests, and daily use is straightforward from the first charge.

Flavour and performance notes
A representative profile is Grape Frost Breeze: sweet, fruity, described as dark grape with a cool, brisk finish. On a 80:20 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 1.4 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 1.4 Ω mesh and the Type-C fast charge are both in stock before committing, and check that the Q-Plus 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.
