XMAX V4 Pro vs PAX Plus: Convection or Conduction Under €100?
In short: Two of the most popular budget portables take completely different approaches. The V4 Pro uses pure convection with a swappable 18650 battery and heats up in 10 seconds. The PAX Plus goes conduction with a sealed 3300 mAh battery, app control, and 10-year warranty. The V4 Pro wins on flavor extraction and repairability; the PAX Plus wins on build quality, discretion, and long-term support.

Vapor Quality
This is where the heating method makes the biggest difference. The V4 Pro’s convection system heats the herb with hot air passing through the chamber — you get more flavor, especially at lower temperatures around 180–195 °C. Terpene profiles come through clearly, and the vapor feels lighter with less harshness.
Key fact: The XMAX V4 Pro (from 88 EUR) uses pure convection producing cleaner flavor, while the PAX Plus (from 134 EUR) uses conduction for faster extraction. The V4 Pro costs roughly half the PAX Plus but delivers arguably better vapor quality through its convection approach (Vapochecker, 2026).
The PAX Plus uses conduction, meaning the chamber walls heat up and cook the herb from the outside in. Vapor production is consistent and clouds tend to be thicker, but the flavor profile is less nuanced. Stirring the bowl mid-session helps with even extraction, which the V4 Pro doesn’t need.
If flavor is your priority, the V4 Pro has a clear edge. If you prefer thick clouds and don’t mind a slightly roastier taste, the PAX Plus delivers reliably.

Battery and Daily Use
The PAX Plus packs a larger 3300 mAh battery that lasts roughly 8–10 sessions. The downside: when it degrades after 2–3 years, you can’t replace it. The V4 Pro uses a standard 18650 cell (2550 mAh, ~6–7 sessions) that you can swap in seconds — carry a spare and you effectively have unlimited battery life.
Both support passthrough charging via USB-C. The PAX Plus has a slight edge in portability — it’s one of the slimmest portable vaporizers on the market. The V4 Pro is a bit taller but still pocketable.
Build Quality and Warranty
PAX builds the Plus from anodized aluminum with a brushed finish. It looks and feels premium. The 10-year warranty is industry-leading and covers manufacturing defects. PAX has a reputation for honoring warranty claims quickly.
The V4 Pro uses a combination of metal and high-grade plastic. Build quality is solid for the price but doesn’t match PAX’s fit and finish. The 1-year warranty from XMAX/TopGreen is standard for the budget segment.
Who Should Buy Which?
Choose the V4 Pro if you:
- Want the best flavor under €100
- Prefer swappable batteries for longevity
- Like tinkering (water pipe, different stems)
- Don’t need an app
Choose the PAX Plus if you:
- Value build quality and premium materials
- Want a 10-year warranty
- Need a discreet, slim design
- Like app control for custom temperature profiles
Bottom line: The V4 Pro is the better vaporizer for pure vapor quality at a lower price. The PAX Plus is the better product — polished, warrantied, and built to last a decade. Your choice depends on whether you prioritize extraction quality or the total ownership experience.
