A height adjuster and a dial adapt the chamber to different cartridges. Yocan specifies 8–14 mm diameter and marks the height specification on the current product page as over 42 mm. Two magnetic adapters of different lengths are included. Check the dimensions of your own cartridge and the 510 connection before purchasing.
According to the manufacturer's instructions, the voltage can be set between 1.8 and 4.2 V. The pre-heat mode operates for 10 seconds at 1.8 V. The 1.26-inch TFT displays operating information in color. Adjustment is made via the device; precise temperature control in °C is not specified for this cartridge battery device.
The built-in battery has 650 mAh and charges via USB-C. The current product page states automatic shut-off after one hour. The package includes the UNI 4.0, two magnetic adapters, instructions, and a USB-C cable. A cartridge, liquid, or herbs are not included.
The UNI 4.0 supplies power to a compatible, separately inserted cartridge. Material contact, heating coil, and fill depend on that cartridge. For this reason, neither a specific heating chamber material nor suitability for loose herbs can be derived from the battery specifications.
Same device type and a similar price; matching heating methods come first. Size and features may differ.
