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, 2550 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?

Wolkenkraft Aeris Ultra — The European Option
The Aeris Ultra is sold under the German Wolkenkraft brand (a Fenix rebrand) and is widely available across Europe. The convection chamber uses a glass mouthpiece system reminiscent of Arizer. 25-second heat-up, clean and consistent vapour. The 2550 mAh battery lasts 5 to 6 sessions. Active community in Germany and the Netherlands. EU customer service included. From ~€94 — Aeris Ultra price comparison
Key fact: The Wolkenkraft Aeris Ultra (from 139 EUR) and XMAX V4 Pro (from 88 EUR) are the two most affordable pure convection vaporizers tracked across 361 devices. Both use replaceable 18650 batteries and offer on-demand capability (Vapochecker, 2026).
XMAX V4 Pro — The Value Champion
The V4 Pro heats up in about 10 seconds (manufacturer: no more than 20 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. If even €69 is more than you want to spend, the older XMAX V3 Pro is the predecessor and a step down in price — hybrid heating with a replaceable 18650 battery and a ceramic vapor path. From ~€69 — V4 Pro price comparison

Vapour Quality
Both deliver pure convection vapour at up to 220 °C. The Aeris Ultra benefits from its glass mouthpiece — short vapour path, clean flavour. The V4 Pro uses a plastic mouthpiece, minimally less neutral at high temps. In community comparisons, both score close, with a slight flavour edge to the Aeris Ultra at lower temperatures.
