PAX Flow vs VENTY: Two Philosophies Compared
With the PAX Flow, PAX Labs is bringing a hybrid vaporizer to market for the first time. All previous PAX models relied on pure conduction – the Flow breaks with this tradition. At 135 grams, it weighs roughly half as much as the VENTY from Storz & Bickel (252 g). Two fundamentally different approaches: Californian minimalism with fixed heating modes and no app, versus Swabian engineering with a display, degree-precise temperature control, and adjustable airflow.

In brief: The PAX Flow is lightweight, requires no app or Bluetooth, and operates with five fixed heating modes. The VENTY has an LC display, degree-precise temperature selection, adjustable airflow, is compatible with dosing capsules, and lasts considerably longer per battery charge.
Current prices: PAX Flow from ~232.16 € Code VAPOCHECKER5 · incl. shipping at 165 shops and VENTY from ~265.88 € Code VAPOCHECKER5 · incl. shipping at 209 shops.
PAX Flow – Minimalist, Lightweight, No App
The PAX Flow weighs 135 grams. For comparison: that is less than most smartphones. Unlike the PAX Plus and PAX Mini, the Flow has neither Bluetooth nor an app. It is operated on the device via a button and LED indicators – there is no display.
Instead of a freely selectable temperature, PAX offers five heating modes with a fixed temperature curve, including one optimized for use with a water pipe. PAX does not publish exact values for the individual modes. According to the PAX manual, the Flow is ready after approximately 45 seconds. The battery has 2000 mAh; PAX itself states approximately three sessions or around 30 minutes of vapor time per charge. Via USB-C, it charges to full in under 40 minutes with fast charging, or approximately 90 minutes otherwise.
What’s missing: no adjustable airflow, no dosing capsules, no display, no app. In return, there is nothing to set up – select a mode, wait, vaporize.
Warranty: 2 years, with registration within 30 days a total of 4 years. Water pipe: yes, with separately available adapter (14 and 18 mm).

VENTY – Display, Airflow, Dosing Capsules
The VENTY is Storz & Bickel’s portable flagship device. 252 grams, LC display, steplessly adjustable airflow up to 20 liters per minute, compatible with dosing capsules (not included). The heat-up time is approximately 20 seconds according to the manufacturer – less than half as long as the PAX Flow.
The LC display shows actual and target temperature in real time. Two buttons on the device regulate the temperature between 40 and 210 °C in 1 °C increments. Additionally, Storz & Bickel’s web app is available via Bluetooth for custom Boost levels and firmware updates. It runs in the browser; no installation is required.
The VENTY is powered by two built-in 18650 lithium-ion cells; Storz & Bickel does not publish a mAh figure. In tests, a single charge lasted for 10 to 14 bowls. It charges via USB-C, reaching 80% in 40 minutes with S&B’s Supercharger. The VENTY does not support vaporizing whilst charging (passthrough). The steplessly adjustable airflow remains a unique feature – from a tight cigarette-style draw to a wide lung hit.
Warranty: 2 years, 3 years after registration. Temperature range: 40–210 °C.

Heating and Vapor Quality
Both devices rely on hybrid heating: conduction via the chamber walls plus convection through hot air. For PAX, this is a novelty – all predecessors (PAX 2, PAX 3, PAX Plus, PAX Mini) heated using pure conduction. Storz & Bickel has used the combination since the Mighty and has refined it further with the VENTY.
The two devices take different approaches to temperature. The PAX Flow operates via five heating modes with a fixed curve, one of which is tailored for use with a water pipe. The VENTY can be set between 40 and 210 °C to the nearest degree, with additional Boost levels. Anyone who wants to know exactly what temperature they are vaporizing at will only get that with the VENTY.
The two devices also diverge when it comes to airflow: the VENTY offers stepless adjustment, from tight resistance to wide open. The PAX Flow has a fixed airflow. Anyone who likes to tailor their draw to their own preferences can only do so with the VENTY.
Heat-up time: 20 seconds versus approximately 45. The VENTY is noticeably faster here. For frequent on-demand switching on and off, this makes a difference.
Battery and Everyday Usability
The PAX Flow has a battery with 2000 mAh; PAX states approximately three sessions per charge for this. The VENTY has two built-in 18650 cells whose capacity Storz & Bickel does not publish; in tests, a single charge lasted 10 to 14 bowls. For a weekend without a charger, the VENTY is the safer choice.
On weight, the PAX Flow comes out ahead: 135 grams versus 252 grams. The Flow disappears into a jacket pocket; the VENTY is no brick, but noticeably heavier. Those who prioritize mobility should go for the PAX Flow.
Both charge via USB-C. The PAX Flow charges to full in under 40 minutes with fast charging; the VENTY reaches 80% in 40 minutes with the Supercharger. Vaporizing whilst charging is not possible with the VENTY.
Operation and Controls
Two different philosophies are evident here. With the Flow, PAX has deliberately dispensed with an app and Bluetooth: one button, LED indicators, five heating modes. This can be learnt in a few minutes and requires no phone, but does not allow a custom target temperature.
Storz & Bickel relies on the LC display with the VENTY: temperature and battery level can be read and adjusted directly on the device. The browser-based web app is optional and serves for Boost levels and firmware updates. It requires no download, but does not offer push notifications.
Dosing capsules are usable with the VENTY and practical for on-the-go use: pre-fill, insert, remove cleanly. The PAX Flow does not offer this – direct filling only.

Frequently Asked Questions
Is the PAX Flow really a hybrid vaporizer?
Yes. The PAX Flow is the first PAX model with hybrid heating (convection plus conduction). All earlier PAX devices used conduction exclusively.
Can I set the temperature precisely on the PAX Flow?
Not to the nearest degree. The PAX Flow works with five heating modes with a fixed temperature curve, the exact values of which PAX does not publish. The VENTY can be set between 40 and 210 °C in 1 °C increments.
Is there an app for the PAX Flow?
No. The PAX Flow has neither Bluetooth nor an app; it is operated via a button and LED indicators. The VENTY can additionally be controlled optionally via Storz & Bickel’s web app in the browser, in addition to the display.
Which has the better battery?
The VENTY. The PAX Flow has 2000 mAh, which PAX states is good for approximately three sessions per charge. The VENTY does not state a capacity, but achieved 10 to 14 bowls per charge in testing. That said, the PAX Flow charges to full in under 40 minutes with fast charging.
Which is better suited for use on the go?
It depends. The PAX Flow weighs 135 g and fits anywhere. The VENTY has the longer battery life and dosing capsules for clean operation. For short trips: PAX Flow. For multi-day trips: VENTY.
Conclusion
PAX Flow and VENTY serve different needs. The PAX Flow is for those who want a lightweight hybrid device without an app and without any setup. The VENTY is for those who need a display, degree-precise temperature, airflow control, dosing capsules, and more sessions per charge. Both are hybrid vaporizers – only the approach differs fundamentally.
