Quick summary: PAX’s most significant hardware redesign in years — their largest device, their first with USB-C charging, and their first with draw-adaptive heating. At $350, it’s their most expensive vape yet, and it has some very real problems that must reconsidered before purchase - mainly the hot exterior and short battery life.
PAX Labs is a US-based vaporizer company founded in 2007 in San Francisco. Originally known for the first PAX vaporizer, they have since released the PAX 2, PAX 3, PAX Mini, PAX Plus, and now the Flow.

Questions and things to find out over time:
- How does draw-adaptive heating actually behave in practice — does it noticeably shift between slow sips and hard rips?
- Does the 35-min continuous use claim hold at higher temps in real-world testing?
- Cleaning ease with the side-mounted oven door compared to previous PAX designs?
- How does it compare to the Venty or Solo 3 at the $350 price point?
