Verdampfer draw technique: breakdown edition (90 W)
Verdampfer advice for Beijing, covering draw technique, what to look for and where the trade-offs actually sit.
Most Beijing buyers start with a well-known brand name and then discover that fit and coil availability matter far more. Comparing this against a 55:45 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume.
Local availability in Beijing shapes the practical answer more than the marketing does. For rechargeable users, the learning curve is shorter than the specification list suggests, and daily use is straightforward from the first charge.
Expect roughly 759 full puffs from a charge at 10 mg/ml, based on average session length in our testing. Delivery across Beijing is typically two to four working days with tracked dispatch, and returns are straightforward within the standard window. 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.
Charging over Micro-USB takes about 41 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 Micro-USB socket on the base and whether the 0.6 Ω mesh coil is the newer generation. Battery behaviour is where the RELX Pro earns its keep: the 4000 mAh cell holds a usable charge for most of a day at 70 and recharges over Micro-USB.
The wide bore mouthpiece is comfortable over long sessions and resists the condensation that gathers on narrower tips. 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 RELX Pro earns its keep: the 4000 mAh cell holds a usable charge for most of a day at 70 and recharges over Micro-USB.
The included spare coils are useful for the first fortnight, after which you will be ordering your own. What surprised us most was how little the 0.6 Ω mesh coil changes the draw character compared with the 55:45 PG/VG liquid sitting in the chamber. The Ocean Teal finish hides fingerprints far better than the gloss options, which matters more than it sounds on a device handled daily.

Flavour and performance notes
A representative profile is Cherry Lime Soda: sweet, tart, described as red cherry with a lime lift. On a 55:45 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 0.6 Ω mesh mark before the coil begins to mute it.
Practical considerations in Beijing
Availability in Beijing is the factor that decides most outcomes here. Confirm the 0.6 Ω mesh and the Micro-USB are both in stock before committing, and check that the Q-Plus matches your existing device if you already own hardware. Duty and CNY rates move, so treat prices as current rather than fixed.
Take the time to get it right the first time; the difference shows up over months of use rather than days.
