The Wolkenkraft FX Mini Ultra is the smallest vaporizer the German brand makes, and it sits at the accessible end of the range. It is consistently rated among the best compact portables, mostly for how much it gives back for its size.

That pocket-sized body keeps the vapour path short and direct, which is how it delivers such clean flavour and stays easy to maintain. Vapour does arrive warm above about 200°C, but around 190°C it stays comfortable, and the included capsule system means you pre-load at home and carry a session ready to go.

At 5.0 × 2.8 × 8.1 cm and 141 g, the FX Mini Ultra fits a trouser pocket beside your phone. Held in a closed fist, only the glass mouthpiece shows. The weight feels dense for the size, which reads as solidity in the hand.

The matte soft-touch finish is warm and grippy, with gold-plated rings around the mouthpiece and a small round window into the chamber. To anyone a few metres away it looks much like a normal e-cigarette.

The silicone dust cap that comes in the box slips over the mouthpiece for pocket carry. It keeps lint out of the glass and holds the smell in between sessions.

The FX Mini Ultra heats by convection. The heater warms the air as you inhale, and that hot air travels up through the load like warm air rising through a vent, so nothing sits pressed against a hot metal wall.

The titanium chamber has a rounded shape, so air moves around the whole load. The air path is sealed from the inlet to the chamber, which means every bit of air you pull passes over the heating element first.

The FX Mini Ultra heats up in about 25 seconds, roughly the time it takes to grind a load. Because heat is only made while you inhale, herbs can sit between draws without being cooked.

The vapour path is almost entirely glass. A full-length borosilicate glass mouthpiece runs the whole inner path, with only about 8 mm of silicone in the path, so flavour comes through clean and single herbs stay recognisable.

The draw itself is one of the most praised parts of this vape. There is almost no resistance, even with a full chamber, so you can inhale slowly and softly without effort. That makes it a strong choice for anyone with limited lung power.

You can also pull the glass mouthpiece out a little to lengthen the air path, which takes some of the heat out of the vapour at higher settings.

The FX Mini Ultra runs from 100°C to 220°C in 1°C steps. There are no presets to work around, and it remembers your last setting. The 0.66" OLED shows the set temperature, the live temperature, the battery level and the session countdown at once.

Lower settings between 160°C and 190°C preserve lighter compounds and give the most flavour-forward draws. Settings between 195°C and 220°C extract the load more completely in fewer minutes. A common approach is starting near 190°C and stepping up towards the end.

The session timer can be set to 3, 4 or 5 minutes, and the vape vibrates and shuts off when it expires. The display shows one fixed orientation and cannot be flipped, so the screen faces you when you hold the vape upright.

If you like running above 200°C, the glass bubbler (sold separately) is the accessory owners reach for. It slides into the same socket as the glass mouthpiece and cools the vapour through a small amount of water.

The titanium chamber takes a loose fill of ground herbs. Fill it full but do not compress it, and wipe the rim before closing so the silicone seal seats properly. The magnetic slide-in mouthpiece holder pulls straight up and snaps back into its rail.

Two steel dosing capsules and a keyring caddy are included in the box. Each capsule holds about 0.1 g when filled, and the manual suggests filling them around halfway to leave room for air to move. Pre-load them at home, clip the caddy to your keys, and a swap takes a moment.

Capsules also keep resin off the chamber walls, so deep cleaning comes around far less often. You can build the system out with extra herb capsules, a filling tool for loading them without spills, and a second capsule container, all sold separately.

Three buttons handle everything, and five quick clicks of the top button switch the vape on and off. Here is a full session from start to finish.

1. Loading: Grind your herbs, lift the mouthpiece holder straight out of its rail, and fill the chamber loosely to the top. A pre-filled capsule drops straight in instead.
2. Closing: Wipe the chamber rim clean, slide the mouthpiece holder back until the magnet snaps home, and push the glass mouthpiece down until it seats into the lower rubber ring.
3. Powering on: Press the top button five times. The screen lights up and the vape gives a short buzz.
4. Setting: Use the up and down buttons to set the temperature in 1°C steps. Hold the top button for about two seconds to set the session length to 3, 4 or 5 minutes.
5. Heating: Wait about 25 seconds. The light turns from red to blue and the vape vibrates when it reaches temperature.
6. Inhaling: Hold the vape by the sides so your fingers stay clear of the air inlet on the bottom. Take two short priming puffs, then draw slowly and softly.
7. Finishing: The vape vibrates and switches off when the timer runs out. If you finish early, five clicks turn it off and save battery. Let the top cool for a moment before you lift the mouthpiece and empty the chamber.

The 1600 mAh battery gives around 4 to 6 sessions per charge, which suits a day of normal use more than a full day of hiking. The cell is built into the body and is not designed to be swapped by the user.

Charging runs over USB-C and is about 30% faster than the previous FX Mini, reaching full in roughly 90 minutes. The port sits on the bottom, next to the air inlet. Pass-through charging is supported, so you can carry on vaping while it is plugged into a charger, a laptop or a power bank.

The top of the body and the capsule inside get noticeably hot after a full session, so give it a moment before you pop the capsule out. A 120 cm USB-A to USB-C cable is included, though no wall adapter comes in the box. Any USB-A phone charger rated at 7 W or above will work.

The glass mouthpiece runs the entire inner path, so residue collects on a part you can pull out and wash. The black housing inside stays clear of condensate. Rinse the glass in isopropyl alcohol every few sessions and let it dry fully.

The chamber needs a quick brush after each session once it has cooled, using the wooden brush from the box. Its flat end doubles as a packing tool. The mouthpiece screen collects fine particles fastest, so pop it out with the tweezers and soak it whenever the draw starts to tighten.

The sealed internal air channel is not meant to be flushed through. Keeping the screen, the glass and the chamber rim clean is what keeps the airflow open.

Wear items are worth keeping in a drawer. The silicone ring with mouthpiece screen and spare mouthpiece screens are both available separately, and a replacement mouthpiece covers the day a glass piece meets a tiled floor.

The ÄRiS Ultra is Wolkenkraft's mid-range convection portable, a larger body with a longer air path and the same titanium chamber philosophy. It produces clearer, softer vapour with more depth of flavour, has a built-in stirring tool, and is easier to clean throughout.

The FX Mini Ultra answers with the most compact body Wolkenkraft makes, small enough to disappear in a fist. It pulls remarkably freely for its size, while the larger model trades a little openness for a longer, more directed path. In terms of what each one produces per session, the two are closely matched.

If you want a longer, cooler path and simpler full cleaning at home, the ÄRiS Ultra earns its extra size. For carrying a vape everywhere without noticing it, the FX Mini Ultra is the specialist.

The XMax V4 Pro is a compact, value-focused portable known for packing enthusiast features into a low price. It offers an airflow dial, a user-replaceable battery, a glass water pipe adapter in the box, and on-demand heating.

The FX Mini Ultra counters with five years of warranty cover, far longer than the protection typical in this class. Its titanium chamber feeds a full-length glass mouthpiece, so residue lands on removable glass. Single-degree control across 100°C to 220°C, a live OLED readout and pass-through charging round it out.

The V4 Pro is the pick if an airflow dial, swappable cells and bundled glass matter most. The FX Mini Ultra is the pick for a smaller body, a titanium and glass path, and five years of cover behind it.

Right now we offer a 25% discount on all accessories when you buy any vaporizer here at MagicVaporizers. Here is a short guide to what works well alongside the FX Mini Ultra.

Glass Bubbler: Adds water filtration for cool, comfortable draws at 200°C and above, and it slides into the mouthpiece socket without tools.

Steel Capsule for Herbs: Extra capsules let you fill several at once at home, so an evening out needs no grinder.

Capsule Container: The included caddy holds two capsules; a second container carries a full day of pre-loaded sessions.

Filling Tool: Solves the fiddly job of getting ground herbs into small capsules without scattering them across the table.

Steel Capsule for Concentrates: For the occasional session with waxes and oils, keeping sticky material off the titanium chamber.

Quartz Capsule for Concentrates: The quartz glass version for anyone who picks up a metallic edge from steel.

TightVac MiniVac: An airtight pocket container that keeps ground herbs fresh and holds the smell in while you carry them.

USB-C Fast Charger (45W): The vape ships without a wall adapter. This GaN charger handles it at home or on a trip.

Dust Cap: The cap is small and easy to lose, and it is what makes pocket carry clean and quiet.

Silicone Ring with Mouthpiece Screen: The main wear part. A hardened seal is the usual cause of weak, cool-feeling draws.

Mouthpiece Screens: Keeping two screens in rotation means you never wait for one to finish soaking.

Half-Black Mouthpiece: A replacement glass mouthpiece in a darker finish, useful the day a drop ends badly.

Full Mouthpiece Set: The complete mouthpiece assembly, for a full colour change or a replacement beyond just the glass.
