Short answer: the XMAX V4 Pro is a portable convection vaporizer with session and on-demand modes, adjustable airflow and a replaceable 18650 battery. TopGreen’s own pages disagree on battery capacity: the product page states 2,550 mAh, while the support FAQ states 2,600 mAh. We therefore do not present either number as a single settled specification.
All prices come from automated shop queries. Some shop links are affiliate links.
What this page does: it checks the V4 Pro against current manufacturer material; it is not presented as a long-term laboratory test. For the buying decision, see XMAX V3 Pro vs V4 Pro. For shops, availability and live prices, use the XMAX V4 Pro price page. Evidence status updated 9 August 2026.

What the manufacturer actually confirms
The product listing confirms a stainless-steel heating chamber, an isolated air path, a colour OLED display and a temperature range of 100–220 °C. The support FAQ describes pure convection, a typical heat-up of about 10 seconds and at least twelve six-minute sessions at 220 °C. That session figure is a manufacturer claim under one stated test condition, not a universal runtime promise.
What remains unverified
Battery capacity: 2,550 and 2,600 mAh are both published by TopGreen.
Device weight: the checked manufacturer pages do not publish a verifiable figure.
Pass-through charging: USB-C is documented, but use while charging is not confirmed on the checked pages.
Hands-on performance: VapoChecker currently has no documented first-hand test protocol or original test photos for this model, so this page does not claim them.
XMAX V4 Pro or V3 Pro?
The documented distinction is the heating design: TopGreen describes the V4 Pro as convection, while the V3 Pro is the older alternative. Choose based on current price, the preferred mode and available accessories rather than an unsupported performance score.
