Beijing Verdampfer comparison chart (AEKU Slim) (v2)
Verdampfer advice for Beijing, covering best practice, 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. Expect roughly 473 full puffs from a charge at 3 mg/ml, based on average session length in our testing.
Local availability in Beijing shapes the practical answer more than the marketing does. Airflow control on the Deng SQ200 is adjustable enough to move from a warm, restrained draw to something far more open without removing the tank.
Battery behaviour is where the Deng SQ200 earns its keep: the 650 mAh cell holds a usable charge for most of a day at 100 and recharges over Micro-USB. We would pair the Deng SQ200 with a 70:30 PG/VG liquid, which is where the balance between throat hit and cloud density sits most comfortably. Replacement coils are widely available, and the 1.2 Ω mesh coil is the sensible default to keep in stock.
Airflow control on the Deng SQ200 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 100, 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.
Comparing this against a 70:30 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume. The 4.0 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem. Expect roughly 473 full puffs from a charge at 3 mg/ml, based on average session length in our testing.
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 1.2 Ω mesh mark before the profile flattens and a swap makes sense. In Beijing, availability of the 1.2 Ω mesh coil is the practical bottleneck, not the device itself.
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 70:30 PG/VG blend, so if you prefer a smoother draw, mix accordingly. Pricing in Beijing shifts with import duty, so the figures here reflect current CNY rates rather than a fixed list price.

Flavour and performance notes
A representative profile is Raspberry Lemonade: sweet, tart, described as summer lemonade with a raspberry accent. On a 70:30 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 Beijing
Availability in Beijing is the factor that decides most outcomes here. Confirm the 1.2 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.
