Aeris Ultra vs. XMAX V4 Pro: Which Budget Convection Vaporizer Wins?
Two of the most recommended convection vaporizers under €100 — from different worlds. The Wolkenkraft Aeris Ultra is the European answer to affordable convection: around €94, 25-second heat-up, 2600 mAh battery. The XMAX V4 Pro from China counters with €69, 11-second heat-up, and a WPA adapter in the box. Both reach 220 °C. Both use pure convection. But the €25 gap raises a question: what do you get for the extra money?
Current prices: Aeris Ultra from ~€94 and V4 Pro from ~€69.

The convection chamber uses a glass mouthpiece system reminiscent of Arizer. 25-second heat-up, clean and consistent vapour. The 2600 mAh battery lasts 5 to 6 sessions. Active community in Germany and the Netherlands. EU customer service included. From ~€94 — Aeris Ultra price comparison
XMAX V4 Pro — The Value Champion
The V4 Pro heats up in 11 seconds — more than twice as fast. Temperature adjusts in 1 °C steps. 14 mm WPA adapter included. 2550 mAh battery — nearly identical to the Aeris Ultra. All for €69. From ~€69 — V4 Pro price comparison
