Tanks and clearomizers reviews: tested in Liverpool (AEKU Slim) (v2)

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

We spent weeks putting tanks and clearomizers options through their paces so the recommendations here reflect real use. Flavour tracking stays consistent from the first day to roughly the 1.0 Ω mesh mark before the profile flattens and a swap makes sense.

Most Liverpool buyers start with a well-known brand name and then discover that fit and coil availability matter far more. The included spare coils are useful for the first fortnight, after which you will be ordering your own.

Battery behaviour is where the RELX Pro earns its keep: the 1200 mAh cell holds a usable charge for most of a day at 200 and recharges over USB-C. 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. Replacement coils are widely available, and the 1.0 Ω mesh coil is the sensible default to keep in stock.

In Liverpool, availability of the 1.0 Ω mesh 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. Comparing this against a 80:20 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume.

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 1.0 Ω mesh mark before the profile flattens and a swap makes sense. In Liverpool, availability of the 1.0 Ω mesh coil is the practical bottleneck, not the device itself.

The 2.5 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem. Expect roughly 1072 full puffs from a charge at 0 mg/ml, based on average session length in our testing. Replacement coils are widely available, and the 1.0 Ω mesh coil is the sensible default to keep in stock.

Charging over USB-C takes about 78 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 1.0 Ω mesh coil is the newer generation. Battery behaviour is where the RELX Pro earns its keep: the 1200 mAh cell holds a usable charge for most of a day at 200 and recharges over USB-C.

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 USB-C takes about 78 from empty, and the pass-through means the device can be used while plugged in on the smaller batteries.

Specifications

Every unit in the RELX Pro family shares the same core platform, so the differences come down to the numbers below.

Flavour and performance notes

A representative profile is Lemon Lime Soda: citrusy, crisp, described as zesty lemon over lime with gentle carbonation. On a 80:20 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 1.0 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 1.0 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.
