Mixing Ratios Tanks and clearomizers explained (Uwell Calibre)
Tanks and clearomizers advice for Liverpool, covering mixing ratios, what to look for and where the trade-offs actually sit.
There is no single best tanks and clearomizers for everyone in Liverpool, and anyone telling you otherwise is selling something. The throat hit is noticeably firmer than a 65:35 PG/VG blend, so if you prefer a smoother draw, mix accordingly.
There is no single best tanks and clearomizers for everyone in Liverpool, and anyone telling you otherwise is selling something. The instruction booklet is thin, but the diagrams are clear enough that most people set the device up without further help.
Two things to check before ordering: the Type-C fast charge socket on the base and whether the 1.2 Ω mesh coil is the newer generation. Battery behaviour is where the Robust Pro earns its keep: the 800 mAh cell holds a usable charge for most of a day at 90 and recharges over Type-C fast charge. We would pair the Robust Pro with a 65:35 PG/VG liquid, which is where the balance between throat hit and cloud density sits most comfortably.
The 8.0 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem. Expect roughly 1336 full puffs from a charge at 12 mg/ml, based on average session length in our testing. Replacement coils are widely available, and the 1.2 Ω mesh coil is the sensible default to keep in stock.
Comparing this against a 65:35 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume. Vapour production is more than adequate at 90, and pushing beyond that adds heat rather than anything worth carrying. Expect roughly 1336 full puffs from a charge at 12 mg/ml, based on average session length in our testing.
The Emerald finish hides fingerprints far better than the gloss options, which matters more than it sounds on a device handled daily. Worth noting that the magnetic contact takes a small amount of care to keep clean, which we cover in the maintenance section below. For experienced users, 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 Classic Menthol: cool, sharp, described as clean peppermint with consistent coolness. On a 65:35 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 1.2 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 1.2 Ω mesh and the Type-C fast charge 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.
Our advice is to order one, use it for a fortnight, and only then decide whether to stock up.
