Tanks and clearomizers upgrades and spare parts (RELX Pro)

Tanks and clearomizers advice for Liverpool, covering warranty, what to look for and where the trade-offs actually sit.

Anyone who has compared tanks and clearomizers options in Liverpool quickly learns that specification lists only tell part of the story. The instruction booklet is thin, but the diagrams are clear enough that most people set the device up without further help.

Most Liverpool buyers start with a well-known brand name and then discover that fit and coil availability matter far more. Build quality is the quiet differentiator here, with tight seams and a connector that has not loosened after repeated removal.

The Stealth Grey 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 bottom pin 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.

What surprised us most was how little the 1.5 Ω regular coil changes the draw character compared with the 55:45 PG/VG liquid sitting in the chamber. Charging over Type-C fast charge takes about 37 from empty, and the pass-through means the device can be used while plugged in on the smaller batteries.

The included spare coils are useful for the first fortnight, after which you will be ordering your own.

In Liverpool, availability of the 1.5 Ω regular coil is the practical bottleneck, not the device itself. The silicone tip mouthpiece is comfortable over long sessions and resists the condensation that gathers on narrower tips. Two things to check before ordering: the Type-C fast charge socket on the base and whether the 1.5 Ω regular coil is the newer generation.

Comparing this against a 55:45 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume. Battery behaviour is where the AEKU Slim earns its keep: the 800 mAh cell holds a usable charge for most of a day at 60 and recharges over Type-C fast charge. We would pair the AEKU Slim with a 55:45 PG/VG liquid, which is where the balance between throat hit and cloud density sits most comfortably.

Replacement coils are widely available, and the 1.5 Ω regular coil is the sensible default to keep in stock. The build quality on AEKU Slim 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.

Here is what the engineering actually delivers, without the marketing language.

Flavour and performance notes

A representative profile is Passion Fruit Guava: tropical, tangy, described as tropical duo with a sour-sweet balance. On a 55:45 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 1.5 Ω regular 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 1.5 Ω regular and the Type-C fast charge are both in stock before committing, and check that the 510 bottom pin matches your existing device if you already own hardware. Duty and GBP rates move, so treat prices as current rather than fixed.

Our advice is to order one, use it for a fortnight, and only then decide whether to stock up.
