Wolkenkraft Aeris Ultra

The Aeris Ultra heats the plant material exclusively with hot air that flows through the ceramic chamber. The material does not come into direct contact with the heating element — a key difference from conduction vaporizers such as the Pax Mini or the Airistech Nokiva.

Practical effect: cleaner-tasting vapour, more even extraction across the whole session, less risk of combustion at higher temperatures. The trade-off: longer heat-up time (25 s) and higher component costs compared with pure conduction.

The 2600-mAh battery is significantly larger than in most competitors in this price class:

At medium temperature (~190 degrees), a full charge typically lasts for 5 to 7 sessions of 5 minutes each. At 220 degrees the runtime drops, while at 100–160 degrees (for light aromatic compounds) it rises noticeably.

A premium feature of the Aeris Ultra is pass-through charging: the vaporizer can be used during charging. That is not a given in this price class — the Airistech Nokiva (~63 euros) does not have it, and the Pax Mini only gets it from Pax 3 upwards. For heavy users, it is a concrete added value.

The Aeris Ultra is compatible with dosing capsules — small metal containers with a screen that can be filled individually and swapped in seconds. This is especially practical on the go:

• Prepare several sessions: pre-fill 3-5 capsules at home, take them in a tin, and simply swap when used instead of refilling
• Chamber stays clean: plant material does not come into direct contact with the chamber wall — cleaning interval is extended
• Micro-dosing: smaller amounts per capsule allow more precise dosing than full-chamber fills

Wolkenkraft typically includes a set of dosing capsules in the box, and more can be reordered individually. Note: dosing capsules from different manufacturers are not universally compatible — Wolkenkraft-specific capsules are the reliable choice.

The Aeris Ultra has a 14-mm water pipe connection that fits directly onto standard bongs. Water cooling has two measurable effects:

1. Temperature at the mouthpiece drops — at a temperature setting of 220 degrees, the vapour typically reaches the mouth at 35-40 degrees (instead of 60-70 degrees without water)
2. More aromatic vapour perception through saturation of the inhaled air

For occasional sessions at home, the WPA connection can noticeably improve comfort. On the go, it is a bonus feature that does not have to be used. Anyone who values premium water filtration should look at active diffuser bubblers with low dead space so the vapour is not diluted too much.

25 seconds is competitive for a mid-range convection vaporizer:

The Aeris Ultra sits in the middle: not as fast as the XMAX class, but clearly ahead of the Crafty+. In everyday use, the difference between 14 and 25 seconds is negligible as long as it does not become noticeable during every session.

Wolkenkraft offers the Aeris (basic) and the Aeris Ultra in parallel:

The surcharge of around 25 euros primarily pays off through the larger battery — roughly one to two extra sessions per charge. Anyone using the Aeris at home or in the office and able to charge regularly is fully served by the basic variant. For heavy on-the-go users and weekend trips, the Ultra battery reserve is worth the surcharge.

Wolkenkraft offers several models in parallel:

• FX Mini — 1600 mAh, compact convection entry point
• FX Mini Ultra — 1600 mAh, improved variant of the FX Mini
• FX Plus — 2200 mAh, hybrid heating (convection + conduction)
• Aeris — 2300 mAh, convection, mid-range
• Aeris Ultra — 2600 mAh, the model discussed here
• LIVE — 3000 mAh, top model
• Vita — 1600 mAh, only conduction model

The Aeris Ultra positions itself as a balanced mid-range all-rounder: stronger battery than the FX series, more compact than the LIVE, pure convection (unlike the conduction Vita).

The standard box typically contains: the Aeris Ultra, a mouthpiece, a USB-C charging cable, a set of dosing capsules (4-6 pieces), a cleaning brush, a water pipe adapter sleeve (for the 14-mm WPA) and a German user manual. Wolkenkraft ships directly from Hamburg, and EU shipping is standard.

Accessories directly from the manufacturer: refill dosing capsules in sets of 10, replacement mouthpieces, cleaning tools, and optionally a carry case. Third-party accessories are limited — Wolkenkraft recommends its own material for guaranteed compatibility.

Convection vaporizers such as the Aeris Ultra need less care than pure conduction devices because the plant material does not come into direct contact with the heater:

1. After every session: empty chamber, quick brush cleaning
2. Every 10 to 15 sessions: remove mouthpiece, soak in isopropanol (90 %+) for 15 minutes, brush-clean chamber + air channels
3. Every 30 to 50 sessions: deep cleaning with complete disassembly cycle incl. contacts and screen inspection
4. As needed: clean or replace dosing capsules separately (typically every 50-100 fills)

The official Wolkenkraft care kit contains a cleaning brush and special cotton swabs. For 90 % of maintenance, however, standard cleaning equipment from a chemist is sufficient.

Wolkenkraft gives a 2 years manufacturer warranty on the Aeris Ultra — above average for the 100-euro class (industry standard 1 year). Since Wolkenkraft is based in Germany (Hamburg), warranty handling runs directly within the EU without RMA trips across the Atlantic — a clear advantage over US brands such as Airistech or Pax.

By comparison: Storz & Bickel offers 3 years on the Mighty+, MAD Heaters 2 years on the TEMPEST 2. Wolkenkraft therefore sits in the upper mid-range of the warranty rating and uses its German location as a selling point.

• + Pure convection with even vapour
• + 2600-mAh battery — larger than many competitors
• + Pass-through charging (vaping during charging)
• + Dosing capsule-compatible for on the go
• + 14-mm WPA for direct water filter connection
• + 2 years warranty (above average)
• + German manufacturer with EU support
• + 31 EU shops — wide availability
• − No app control
• − 133 grams — not ultra-portable
• − 25 seconds heat-up time — medium speed
• − Little third-party accessory support compared with large brands

The Aeris Ultra is a solid mid-range convection vaporizer with premium features: dosing capsules, pass-through charging, WPA connection and 2 years EU warranty make it a well-considered choice for buyers who do not want to invest in the top class (Mighty+, Venty) but still want solid convection vapour quality.

Anyone looking for a pure entry point and watching the money: Aeris (basic) is enough. Anyone who wants a high-end premium experience and is happy to invest 300-400 euros: Mighty+ is the class above. Anyone who needs a German brand with EU support, robust battery life and the dosing capsule feature: the Aeris Ultra hits exactly this sweet spot.
