XMAX V3 Pro vs V4 Pro: Specs, Sources & Prices (2026)
Answer first: On the checked manufacturer pages, the V4 Pro’s clearest additions are adjustable airflow and a colour OLED display. Both models are documented with pure convection, a replaceable 18650 battery, USB-C charging, 100–220 °C control, session mode and on-demand mode. Choose the V4 Pro if airflow control matters; otherwise compare the live total cost and availability instead of assuming a large core-spec upgrade.
Evidence reviewed 24 August 2026. This is a source and price comparison, not a hands-on test. Manufacturer claims are identified as such and conflicts remain visible.

What does the V4 Pro add?
The documented upgrade is narrower than many reviews imply. TopGreen explicitly labels the V4 Pro’s airflow as adjustable and its display as a colour OLED. The checked V3 Pro page lists a large OLED but does not make the same adjustable-airflow claim. Those are useful, verifiable differences. They do not by themselves prove better flavour, denser vapour or easier technique.
Both official support pages describe their device as pure convection. Both product pages list the same 100–220 °C range, stainless-steel chamber, session and on-demand modes, isolated air path, USB-C charging and replaceable 18650 format. Claims that the V4 Pro changes the fundamental heating category, or that the V3 Pro is necessarily hybrid, are not supported by the manufacturer pages checked for this comparison.
Battery figures and session claims
The manufacturer’s own pages disagree on battery capacity. Each checked product page says 2550 mAh; each support page says 2600 mAh. That 50 mAh discrepancy may reflect cell revisions or page drift, but the pages do not explain it. VapoChecker therefore presents both values instead of manufacturing certainty.
The support copy also claims at least 12 sessions per full charge under a specific six-minute-session and 220 °C condition. That is a manufacturer claim, not an independent VapoChecker endurance result. Real runtime can change with cell condition, temperature, session duration and use pattern. The comparison does not turn that conditional claim into a universal battery-life promise.
USB-C is documented; pass-through use is not
TopGreen documents Type-C/USB-C charging on both product pages. In the official pages reviewed here, VapoChecker did not find a clear statement that either device can be operated while charging. USB-C and pass-through are different claims, so this page leaves pass-through use unconfirmed.
Which model should you choose?
Choose the V4 Pro when adjustable airflow and the colour display are worth the current price difference to you. Choose the V3 Pro when those additions are not essential and its live checkout total is lower. For either model, compare the available shops, delivery terms and coupon conditions for your destination before buying.
This evidence supports a specification decision, not a claim about subjective vapour quality. VapoChecker has not documented a controlled side-by-side test protocol for this article, so it does not declare a flavour, draw-resistance or battery-life winner.
Primary sources and method
VapoChecker checked the four official TopGreen pages below on 24 August 2026 and mapped only claims visible there into the table. Where product and support pages conflict, both values are shown. Retail prices and shop counts come from the live comparison and remain separate from manufacturer specifications.
