Wolkenkraft FX Mini

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

The advantage over conduction devices is the flavour: because heat is transferred through the air, nothing burns onto the chamber walls. The result is clean, terpene-focused vapour that is particularly convincing at low to medium temperatures. The fact that the FX Mini offers genuine convection in its price class is its strongest selling point – many affordable devices use simpler conduction heating.

The FX Mini allows you to adjust the temperature precisely from 160 to 221 °C in 1-degree increments via the OLED display:

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

Anyone who wants a lower starting temperature for very mild sessions will find it on the FX Mini Ultra (from 100 °C). For most uses, however, the FX Mini's range covers everything you need.

The FX Mini is controlled via a large, clearly legible OLED display directly on the device – without an app or Bluetooth. The display shows the exact target and current temperatures as well as the precise battery level; after switching the device on, the temperature indicator rises quickly.

App-free operation is a plus, especially in this price class: no pairing, no smartphone dependency and no app that may eventually stop receiving updates. Switch it on, select a temperature and vape. This makes the FX Mini robust and ready to use immediately.

One of the FX Mini's features is its extendable Pyrex glass mouthpiece. Glass is flavour-neutral and does not react with the hot vapour, preventing unwanted flavours – a clear advantage over devices that route vapour through heated plastic components.

The extendable design also lengthens the vapour path, cooling the vapour slightly on its way to your mouth. Combined with pure convection, this results in a clear, clean flavour. As glass is breakable, the mouthpiece should be handled carefully and retracted for transport.

The FX Mini contains a built-in 1.600-mAh battery. This is a solid capacity for such a compact device and is sufficient for several sessions; as expected, higher temperatures consume more battery power.

Charging is via USB-C, and pass-through charging is supported: you can use the FX Mini while it is connected to the cable. The battery cannot be replaced, which is common in this class. Anyone needing a longer runtime should consider the larger Wolkenkraft models ÄRiS (2.300 mAh) or LIVE (3.000 mAh). Tip: avoid storing the battery completely empty for extended periods to protect the cells.

The FX Mini supports dosing capsules (Dosing Caps), which can be filled in advance and swapped quickly while on the go. They keep the chamber clean because the material remains inside the capsule.

Unlike the FX Mini Ultra, which includes two Dosing Caps, they are generally purchased separately for the FX Mini. If you want to use capsules from the outset, check before buying or order them separately. Alternatively, simply fill the chamber directly with ground herb – this works just as well and often produces slightly more vapour.

1. Switch on: Press and hold the power button until the OLED display lights up.
2. Fill the chamber: Remove the glass mouthpiece and loosely fill the chamber with medium-fine ground herb, or insert a prepared Dosing Cap.
3. Select the temperature: Adjust precisely between 160 and 221 °C.
4. Heat up: The target temperature is reached in under 30 seconds; the display indicates when it is ready.
5. Draw: Inhale slowly and evenly for around 10 to 15 seconds.

To switch the device off, press and hold the power button again. That is all there is to it – no pairing, no app and no confusing menus.

• Grind: medium-fine and even – with convection heating, a larger surface area results in denser vapour.
• Fill level: loosely but completely fill the small chamber; packing it too tightly restricts airflow through the fine holes.
• Temperature stepping: start at 170–180 °C for flavour, then increase gradually up to 221 °C.
• Draw technique: draw slowly and evenly so that the hot air can penetrate the material.
• Keep the glass mouthpiece clean: clean glass tastes noticeably better than glass with resin build-up.

Because the chamber is small, a finer grind and deliberate temperature stepping are especially worthwhile for extracting plenty of flavour from a small amount of material.

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

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

In short: The FX Mini is the most affordable option with genuine convection. Anyone who wants a little more convenience and a lower minimum temperature should spend slightly more on the Ultra. You can see the price difference above in the price comparison.

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

• FX Mini: the most affordable and simplest entry point.
• FX Mini Ultra: the compact top-tier version with a titanium chamber, session timer and Dosing Caps included.
• 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 most affordable introduction to genuine convection should choose the FX Mini. Anyone wanting a water pipe adapter (which the FX Mini does not have), a larger battery or more convenience should upgrade to the ÄRiS, LIVE or FX Mini Ultra.

In the entry-level segment, the FX Mini competes against devices that often use simpler conduction heating. Its genuine convection heating is the key selling point here:

• Arizer Solo 3 V2: also uses pure convection and offers very long battery life and clean flavour, but is considerably larger and heavier than the pocket-sized FX Mini.
• Storz & Bickel Mighty+: the premium benchmark – in a completely different price and size class.

The FX Mini does not win this comparison through top specifications, but through its value for money and portability: genuine convection, precise temperature control and a glass mouthpiece in a very small, affordable device. Anyone wanting maximum vapour quality or a long runtime should look higher up the range; anyone seeking an affordable introduction with clean flavour will find the FX Mini a good fit.

• After each session: brush out the chamber while the device is still slightly warm – residue is easier to remove at this point.
• Glass mouthpiece: remove it regularly and soak it in isopropyl alcohol for a few minutes, then rinse it with water and allow it to dry completely. Handle it carefully, as glass is breakable.
• Chamber and holes: clean them with a brush and a cotton bud soaked in alcohol to keep the fine air holes clear.
• With Dosing Caps: as the material remains inside the capsule, the chamber becomes dirty more slowly.

It is particularly important to keep the fine convection holes clear – a blocked air path is the most common cause of a restricted draw. A clean FX Mini delivers a fresh flavour over the long term.

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

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

• Little vapour: usually caused by herb that is ground too coarsely or a small chamber that is filled too loosely – grind more finely, fill evenly and select a higher temperature if necessary.
• Only warm air / no vapour: drawing too early. Wait for the heat-up time (under 30 seconds) until the display indicates that the target temperature has been reached.
• Restricted or blocked draw: clean the fine convection holes and the glass mouthpiece – blocked holes are the most common cause.
• Unwanted flavour: clean the glass mouthpiece before first use on a new device; otherwise, the device is due for cleaning.
• Charges slowly: use a high-quality USB-C cable and power adapter.
• Broken glass mouthpiece: replacements can be ordered from Wolkenkraft retailers.

The Wolkenkraft FX Mini is the right choice if you are looking for the most affordable introduction to genuine convection. Pure hot-air convection, precise temperature control from 160 to 221 °C, a Pyrex glass mouthpiece and a very compact, lightweight body make it an uncomplicated, good-tasting everyday device for budget-conscious users and beginners.

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