The WOLKENKRAFT FX MINI ULTRA is a compact convection vaporizer with precise 100–220 °C control, OLED display, vibration and a three-to-five-minute session timer. WOLKENKRAFT states a 20–30 second heat-up time.
In the FX MINI ULTRA, the heating unit first heats the airflow, which then passes through the herb chamber. This means the material does not rest directly on a heating element. WOLKENKRAFT combines this convection principle with a chamber made of titanium. The manufacturer describes the device in the user manual as being for dry herbs; separate concentrate inserts are not included as standard.
100 to 220 °C and approximately 25 seconds of heat-up time
The target temperature can be selected in one-degree increments between 100 and 220 °C. The display shows the target value, current temperature and battery level, while a vibration indicates that the device is ready for use. Depending on the initial temperature, WOLKENKRAFT states that it takes approximately 20 to 30 seconds to start. This makes the device fast enough for short breaks, but it operates as a session vaporizer rather than a true on-demand model.
Retractable glass mouthpiece and compact design
The mouthpiece is made of borosilicate glass and can be pulled part of the way out of its holder. The longer vapor path increases the cooling zone without requiring a separate cooling system to be fitted. Measuring approximately 81 × 50 × 27 millimeters, the housing remains short and wide. The glass makes cleaning easier, but it should be protected during transport because it is less impact-resistant than a plastic mouthpiece.
Adjustable session duration and built-in battery
In addition to the temperature, the duration of a session can be set between three and five minutes. Those who draw more slowly or increase the temperature gradually therefore do not have to restart the heating cycle immediately. The battery is permanently installed in the housing and is charged via USB-C; replacing the cell while traveling is not possible. The chamber and mouthpiece should be brushed out after every use before any residue becomes baked on.
The manufacturer's user manual describes the FX MINI ULTRA as being intended for vaporizing dry herbs. An insert for oils or waxes is not included as standard.
The temperature can be set between 100 and 220 °C in one-degree increments. The target and actual temperatures appear on the display.
WOLKENKRAFT states approximately 20 to 30 seconds. The actual time depends, among other things, on the selected temperature and the device's initial temperature.
No. The battery is built in and is charged via USB-C. Quick cell replacement, as offered by devices with a removable 18650 battery, is not supported.
Pulling it out lengthens the vapor path and therefore the cooling distance. The mouthpiece can be pushed back in or removed for transport and cleaning.
