Wolkenkraft ÄRiS vs ÄRiS Ultra: Is the Upgrade Worth It?

Wolkenkraft had a solid budget convection vaporizer in the ÄRiS , compact, affordable, good for beginners. Then the ÄRiS Ultra replaced it. The original ÄRiS is now discontinued at most shops and only available as leftover stock here and there. If you are looking for a Wolkenkraft today, you will almost certainly end up with the Ultra.

Still, the question comes up: What actually changed? And is the price difference justified if you spot the old ÄRiS on sale somewhere?

Äris Ultra in detail: a closer look at the upgrade

The Wolkenkraft ÄRiS Ultra is the updated version of the original ÄRiS, a German-designed convection vaporizer aimed at the budget-to-midrange market. Wolkenkraft (translates to “cloud power”) is a German brand distributed primarily through verdampftnochmal.de and a handful of EU retailers.

The Ultra version brings meaningful upgrades: faster heat-up, haptic feedback (vibration motor), USB-C charging, and improved vapor path. The ceramic chamber is unchanged in material but slightly redesigned for airflow. The overall form factor remains compact — shorter than a pen, light enough to forget it is in your pocket.

Heating system: convection with ceramic chamber

The ÄRiS Ultra uses convection heating with a ceramic chamber. Hot air flows through a precisely shaped ceramic oven, extracting efficiently across the entire load. The ceramic walls retain heat well and contribute to even extraction, producing clean and flavourful vapor at this price point.

Temperature range: up to 220°C with 4 preset levels accessed via the power button. No precise degree-by-degree control, but the presets cover the practical range well.

Vapor quality and draw experience

The ceramic chamber delivers clean, neutral flavour. No metallic taste, no plastic notes — common complaints in this price segment. The vapor is warm but not harsh at mid-range temperatures (185-195°C). At higher settings the clouds become denser but the device body heats up noticeably.

The mouthpiece is recessed and flat, similar to the DaVinci IQ series. Draw resistance is moderate — not as open as a Mighty+ but easier than conduction-only devices. Three to five draws per temperature step extracts most of the material.

Battery and charging

The Ultra ships with 2600 mAh battery (non-replaceable). Both models use USB-C charging and support passthrough charging. Real-world battery life: 4-6 sessions depending on temperature. Full charge takes approximately 90 minutes.

The non-replaceable battery is the biggest compromise. When the battery degrades after 300-500 cycles (1-2 years of daily use), the entire device needs replacing. For users who value longevity, the DaVinci IQ3 with its replaceable 18650 is a better choice.

What did Wolkenkraft improve?

Bigger battery

The most obvious change: 2600 mAh instead of 2300 mAh. In practice, that means one or two extra sessions per charge. Evening-only users will barely notice. For on-the-go use or longer sessions, it makes a difference.

Key fact: The Wolkenkraft ÄRiS Ultra offers improved battery life (2600 vs 2300 mAh), better build quality at only 133 g, and optimized airflow over the original ÄRiS. Available from 92 EUR across 22 shops, it is one of the most widely available European convection vaporizers (VapoChecker, 2026).

Materials and build quality

The Ultra retains the ceramic heating chamber but with a refined internal geometry for better airflow distribution. Ceramic is flavour-neutral and retains heat consistently across the session. At low temperatures around 180–190 °C, the vapor tastes clean and smooth.

Build quality represents a clear step up. The housing has tighter tolerances, better surface finish, and a matte coating that resists fingerprints. Button feedback is crisp, the mouthpiece seats firmly, and there is no creaking or flex in the body. At 133 g the Ultra is less than half the weight of the original ÄRiS (300 g), making it genuinely pocket-friendly.

Airflow

Wolkenkraft reworked the air path on the Ultra. Vapor flows a bit more freely, reducing draw resistance. Not a massive leap, but noticeable. Through a water pipe with a WPA adapter, the improved airflow makes a real difference.

Any reason to get the original ÄRiS?

If you find the standard ÄRiS somewhere under €30, that is a bargain. For that price, you get a working convection vaporizer with dosing capsule support and WPA compatibility. As a backup device or to try convection vaping for the first time, hard to beat.

But the ÄRiS is being phased out. Spare parts and accessories are getting scarce. If you want a device for the next few years, the ÄRiS Ultra is the safer bet.

Current price

The ÄRiS Ultra currently starts at 92. The standard ÄRiS occasionally surfaces as clearance stock.

Price History

Cleaning and maintenance

The ceramic chamber cleans easily: brush out residue after each session while warm, then swab with isopropyl alcohol weekly. The mouthpiece disassembles into a few parts for deep cleaning. Screen replacement is straightforward with standard 10mm screens.

Compared to the original ÄRiS, the Ultra has a slightly improved airpath that collects less residue. Budget 5 minutes per week for maintenance. The device itself cannot be opened for internal cleaning — if the airpath becomes clogged (rare), contact Wolkenkraft support.

How does the ÄRiS Ultra compare to budget competitors?

The ÄRiS Ultra occupies a niche between the convection-focused XMAX V3 Pro and the design-first PAX Mini. Its convection heating with ceramic chamber delivers clean, flavourful vapor at a competitive price. The main limitation is availability — it is primarily sold through German and EU retailers, while the V3 Pro and PAX Mini are available globally.

Who Should Buy Which?

Choose the Aeris if: you find it under €30 as clearance stock and want a working convection vaporizer on a tight budget. Both models use USB-C charging and support passthrough charging.

Choose the Aeris Ultra if: you want the current model with a bigger battery (2600 mAh), improved build quality at only 133 g, and better airflow. It is the safer long-term choice since spare parts and support continue.

Current prices: Aeris from 78 | Aeris Ultra from 92

Daily use

The ÄRiS Ultra fits into a daily routine without friction. At 133 g it disappears into a jacket pocket. The 25-second heat-up means you can take a draw before your coffee finishes brewing. Four temperature presets are limiting on paper, but in practice most users settle on one or two favourites within the first week.

Battery life covers 4-6 sessions per charge. For evening-only users that is 2-3 days between charges. Heavy users who vaporize 4+ times daily will charge every evening. USB-C passthrough charging means an empty battery never forces a pause.

Long-term ownership

Wolkenkraft offers a 2-year warranty on both models. The ceramic chamber is durable and does not degrade over time. The main long-term concern is the non-replaceable battery: after 300-500 full charge cycles (roughly 1-2 years of daily use), capacity drops noticeably. At that point the entire device needs replacing.

Replacement screens (10 mm standard) and WPA adapters remain available through EU retailers. The Ultra uses the same accessories as the original ÄRiS, so existing owners upgrading can keep their capsules, screens, and adapters.

Verdict

The ÄRiS Ultra is the better vaporizer in every way: bigger battery (2600 vs 2300 mAh), lighter weight (133 vs 300 g), improved airflow, and better build quality. If you want a Wolkenkraft convection vaporizer today, get the Ultra. The original ÄRiS only makes sense as cheap clearance stock , and even then, the Ultra offers significantly more device for the price difference.

Frequently asked questions

Is the ÄRiS Ultra backward compatible with ÄRiS accessories?

Yes. Dosing capsules, WPA adapters, and mouthpieces fit both models.

Is the original ÄRiS still being made?

No. The ÄRiS has been discontinued. Only leftover stock is available at select shops. Wolkenkraft now focuses on the Ultra.

Is the upgrade from ÄRiS to Ultra worth the price?

At retail price, yes. The Ultra offers a bigger battery (2600 vs 2300 mAh), weighs less than half (133 vs 300 g), and has better build quality with improved airflow. Only if you find the old ÄRiS under €30 is the price gap large enough to consider the standard model.

Does the ÄRiS Ultra have app control or Bluetooth?

No. Neither the original ÄRiS nor the Ultra offers app control or Bluetooth connectivity. Temperature is adjusted via the power button with 4 preset levels.

How heavy is the ÄRiS Ultra compared to the original?

The Ultra weighs 133 g, less than half the original ÄRiS at 300 g. This makes the Ultra noticeably more portable and pocket-friendly.

Can you use the ÄRiS Ultra with a water pipe?

Yes. Both the ÄRiS and Ultra are WPA-compatible (water pipe adapter). Standard 14 mm and 18 mm adapters fit both models. Water filtration cools the vapor and makes higher temperatures more comfortable.

Does the ÄRiS Ultra support passthrough charging?

Yes. Both models support passthrough charging, meaning you can vaporize while the device is plugged in via USB-C.
