Wolkenkraft FX Mini

The FX Mini heats by convection: the heating element sits beneath the chamber and warms the air flowing through it. This hot air passes evenly through hundreds of small holes through the herb - the material does not come into contact with a glowing element.

The advantage over conduction devices lies in the flavour: because the heat is transferred via the air, nothing burns onto the chamber walls. The result is a clean, terpene-focused vapour that is particularly convincing in the lower to middle temperature range. The fact that the FX Mini offers true convection in its price class is its most important argument - many affordable devices use simpler conduction.

On the FX Mini, you control the temperature degree-precisely from 160 to 221 °C in 1-degree steps via the OLED display:

• 160–180 °C - mild, aromatic draws with thin, flavour-focused vapour
• 185–205 °C - balanced everyday range combining flavour and vapour quantity
• 205–221 °C - dense, strong vapour with maximum active-compound release

Anyone wanting a lower starting value for very mild sessions will find it with the FX Mini Ultra (from 100 °C). For most uses, however, the FX Minis range covers everything you need.

The FX Mini is controlled via a large, clearly readable OLED display directly on the device - completely without an app or Bluetooth. The display shows the exact target and current temperature as well as the precise battery level; after switching on, the temperature display quickly counts upwards.

App-free operation is a plus point, especially in this price class: no pairing, no smartphone dependence, no app that might eventually stop being maintained. Switch on, choose temperature, vape. That makes the FX Mini robust and ready to use straight away.

One feature of the FX Mini is its extendable mouthpiece made from Pyrex glass. Glass is taste-neutral and does not react with the hot vapour, so no unwanted flavours arise - a clear advantage over devices that route the vapour through heated plastic parts.

The extendable design also lengthens the path the vapour travels, cooling it slightly on the way to the mouth. In combination with the pure convection, this produces a clear, clean flavour. Since glass is breakable, the mouthpiece should be handled carefully and pushed in for transport.

The FX Mini contains a fixed 1.600-mAh battery. For such a compact device, this is a solid value that is enough for several sessions; higher temperatures draw more heavily on the battery, as expected.

Charging is via USB-C, and pass-through charging is possible: you can also use the FX Mini while it is connected to the cable. The battery cannot be replaced, which is common in this class. Anyone needing more runtime should look at the larger Wolkenkraft models ÄRiS (2.300 mAh) or LIVE (3.000 mAh). Tip: do not store the battery completely empty for long periods, as this is gentler on the cells.

The FX Mini supports dosing capsules (Dosing Caps), which you fill in advance and insert for a quick change while out and about. They keep the chamber clean because the material remains inside the capsule.

Unlike with the FX Mini Ultra, where two Dosing Caps are included in the scope of delivery, they are usually bought separately with the FX Mini. Anyone wanting to use capsules from the start should check this before buying or order them as well. Alternatively, you can simply fill the chamber directly with ground herb - this works just as well and often delivers a little more vapour.

1. Switch on: hold down the power button until the OLED display lights up.
2. Fill the chamber: remove the glass mouthpiece and place medium-fine ground herb loosely into the chamber, or insert a prepared Dosing Cap.
3. Choose temperature: set degree-precisely between 160 and 221 °C.
4. Heat up: the target temperature is reached after under 30 seconds; the display shows it.
5. Draw: inhale slowly and evenly for about 10 to 15 seconds.

To switch off, hold the power button down again. There are no more steps - no pairing, no app, no menu jungle.

• Grind: medium-fine and even - with convection, more surface area produces denser vapour.
• Fill quantity: fill the small chamber loosely but completely; pressing too firmly restricts the airflow through the fine holes.
• Temperature ramp: start flavour-focused at 170–180 °C, then increase in stages up to 221 °C.
• Draw technique: draw slowly and evenly so the hot air can penetrate the material.
• Keep the glass mouthpiece clean: clean glass tastes noticeably better than resinous glass.

Because the chamber is small, a finer grind and a deliberate temperature ramp are especially worthwhile for getting plenty of aroma from a small amount of material.

The obvious question: standard FX Mini or FX Mini Ultra? Both are compact convection devices with a 1.600-mAh battery, USB-C and OLED display. The FX Mini is the simpler, more affordable base model, while the Ultra adds several upgrades:

• Temperature: FX Mini from 160 °C, Ultra from as low as 100 °C - more room for mild sessions with the Ultra.
• Mouthpiece/chamber: FX Mini with extendable Pyrex glass mouthpiece; the Ultra has a titanium chamber and a magnetic slide-in mouthpiece.
• Convenience: adjustable session timer, haptic feedback, scratch-resistant OLED and faster charging are only available with the Ultra.
• Dosing Caps: included with the Ultra, separate with the FX Mini.

In short: the FX Mini is the most affordable choice with true convection. Anyone wanting a little more convenience and a lower temperature floor should spend a little more on the Ultra. You can see the price difference above in the price comparison.

This is how the FX Mini fits into the Wolkenkraft range:

• FX Mini: the most affordable, simplest entry point.
• FX Mini Ultra: the compact top version with titanium chamber, session timer and Dosing Caps in the set.
• ÄRiS: larger 2.300-mAh battery and WPA support.
• LIVE: the premium device with 3.000 mAh, Coolscreen module and several operating modes.

Anyone looking for the cheapest entry into true convection should choose the FX Mini. Anyone wanting a water filter adapter (which the FX Mini does not have), more battery or more convenience should move up to the ÄRiS, LIVE or FX Mini Ultra.

In the entry-level segment, the FX Mini competes with devices that often use simpler conduction. Its true convection is the main argument here:

• Arizer Solo 3 V2: also pure convection with very long battery life and clear flavour, but significantly larger and heavier than the pocket-sized FX Mini.
• Storz & Bickel Mighty+: the premium benchmark - an entirely different price and size class.

The FX Mini does not win this comparison through peak specifications, but through its price-performance ratio and handy format: true convection, degree-precise temperature and a glass mouthpiece in a very small, affordable device. Anyone needing maximum vapour quality or long runtime should look higher up; anyone seeking an affordable, clean-tasting entry point is in the right place with the FX Mini.

• After every session: brush out the chamber while the device is still slightly warm - residue then comes away more easily.
• Glass mouthpiece: remove regularly and soak for a few minutes in isopropyl alcohol, then rinse with water and allow to dry completely. Handle carefully, as glass is breakable.
• Chamber and holes: clean with a brush and a cotton bud soaked in alcohol so the fine air holes remain clear.
• With Dosing Caps: because the material stays in the capsule, the chamber gets dirty more slowly.

The fine convection holes in particular should remain clear - a blocked air path is the most common cause of weak draw. A clean FX Mini delivers fresh flavour over a long period.

At around 136 grams, the FX Mini is one of the lightest devices in the Wolkenkraft range and fits effortlessly into any pocket. The housing is solidly made for the price class, and the OLED display is easy to read. The only sensitive component is the Pyrex glass mouthpiece, which should be handled carefully.

Wolkenkraft provides a 2-year warranty against manufacturing defects in the electronics and battery. Wear parts such as the mouthpiece, seals and Dosing Caps are excluded. As a Bavarian manufacturer, Wolkenkraft offers established distribution through which spare parts - such as a new glass mouthpiece - remain available.

• Little vapour: usually ground too coarsely or the small chamber filled too loosely - grind finer, fill evenly and, if necessary, choose a higher temperature.
• Only warm air / no vapour: drawn too early. Wait for the heat-up time (under 30 seconds) until the display reports the target temperature.
• Weak or blocked draw: clean the fine convection holes and the glass mouthpiece - blocked holes are the most common cause.
• Unwanted aftertaste: with new devices, clean the glass mouthpiece before first use; otherwise, cleaning is due.
• Charges slowly: use a high-quality USB-C cable and power supply.
• Glass mouthpiece broken: can be reordered as a spare part through Wolkenkraft retailers.

The Wolkenkraft FX Mini is the right choice if you are looking for the most affordable entry into true convection. Pure hot-air convection, degree-precise temperature from 160 to 221 °C, a Pyrex glass mouthpiece and a very compact, light housing make it an uncomplicated, good-tasting everyday device for price-conscious users and beginners.

It is less suitable if you want a lower temperature floor, more convenience (session timer, slide-in mouthpiece) or Dosing Caps included in the scope of delivery - in that case the FX Mini Ultra is worthwhile - or if you need a water filter adapter (ÄRiS) or a very large battery (LIVE). Anyone looking for a small, affordable device with clean convection vapour gets a fair price-performance package with the FX Mini.
