Care Guide RELX devices explained (Kanger K2)
RELX devices advice for Trinidad, covering care guide, what to look for and where the trade-offs actually sit.
The Trinidad market for relx devices has grown steadily, and the choice on offer now is genuinely broad. The 1.6 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem.
Most Trinidad buyers start with a well-known brand name and then discover that fit and coil availability matter far more. The 1.6 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem.
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 60:40 PG/VG blend, so if you prefer a smoother draw, mix accordingly. Pricing in Trinidad shifts with import duty, so the figures here reflect current TTD rates rather than a fixed list price.
We would pair the Robust Pro with a 60:40 PG/VG liquid, which is where the balance between throat hit and cloud density sits most comfortably. Replacement coils are widely available, and the 0.8 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.
The 1.6 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem. Expect roughly 1051 full puffs from a charge at 20 mg/ml, based on average session length in our testing. Delivery across Trinidad is typically two to four working days with tracked dispatch, and returns are straightforward within the standard window.
The instruction booklet is thin, but the diagrams are clear enough that most people set the device up without further help. The build quality on Robust 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. Airflow control on the Robust Pro is adjustable enough to move from a warm, restrained draw to something far more open without removing the tank.

Flavour and performance notes
A representative profile is Pineapple Ice Cream: creamy, sweet, described as dairy-style pineapple dessert. On a 60:40 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 0.8 Ω mesh mark before the coil begins to mute it.
Practical considerations in Trinidad
Availability in Trinidad is the factor that decides most outcomes here. Confirm the 0.8 Ω mesh and the Type-C fast charge are both in stock before committing, and check that the 510 thread matches your existing device if you already own hardware. Duty and TTD rates move, so treat prices as current rather than fixed.
