Travel Users guide to Nicotine salt liquids (spotlight) (Cola Zero)
Nicotine salt liquids advice for Scotland, covering coil compatibility, what to look for and where the trade-offs actually sit.
There is no single best nicotine salt liquids for everyone in Scotland, and anyone telling you otherwise is selling something. What surprised us most was how little the 2.0 Ω regular coil changes the draw character compared with the 55:45 PG/VG liquid sitting in the chamber.
Budget matters in Scotland, but with nicotine salt liquids the cheapest option is rarely the one that lasts. 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.
Pricing in Scotland shifts with import duty, so the figures here reflect current GBP rates rather than a fixed list price. Airflow control on the AEKU Slim is adjustable enough to move from a warm, restrained draw to something far more open without removing the tank. Vapour production is more than adequate at 90, and pushing beyond that adds heat rather than anything worth carrying.
Materials are unremarkable on paper and feel reassuringly solid in the hand, with no flex in the body at all. 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 2.0 Ω regular mark before the profile flattens and a swap makes sense.
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 2.0 Ω regular 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.
Two things to check before ordering: the USB-C socket on the base and whether the 2.0 Ω regular coil is the newer generation. Battery behaviour is where the AEKU Slim earns its keep: the 800 mAh cell holds a usable charge for most of a day at 90 and recharges over USB-C. 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.
Comparing this against a 55:45 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume. The 3.5 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem. Expect roughly 1530 full puffs from a charge at 0 mg/ml, based on average session length in our testing.

Flavour and performance notes
A representative profile is Raspberry Lemonade: sweet, tart, described as summer lemonade with a raspberry accent. On a 55:45 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 2.0 Ω regular mark before the coil begins to mute it.
Practical considerations in Scotland
Availability in Scotland is the factor that decides most outcomes here. Confirm the 2.0 Ω regular and the USB-C are both in stock before committing, and check that the magnetic contact matches your existing device if you already own hardware. Duty and GBP rates move, so treat prices as current rather than fixed.
Availability shifts often, so check the current listing before committing to a large order.
