Yocan UNI 4.0 – 510 Battery

Yocan UNI 4.0 – 510 Battery

The Yocan UNI 4.0 is a compact box-style battery for 510-thread cartridges. Its adjustable holder fits almost any cartridge, and the colour screen shows your voltage, battery level and puff count at a glance.

Fits almost every cartridge

The cartridge holder adjusts in both height and diameter, so cartridges from 8 to 14 mm fit neatly inside. Your cartridge connects with a magnetic 510-thread adapter, which makes swapping quick and easy. Compatibility always depends on the cartridge itself, so check the specifications of your cartridge.

Full control over every hit

Set the output anywhere between 1.8 and 4.2 V to match your cartridge and taste. Double-click for a 10-second preheat that warms up thicker oils, and use the resettable puff counter to keep track of your sessions.

Slimmer, with a clear display

Compared to the UNI 3.0, the UNI 4.0 is slimmer at 28 mm wide, so it sits more comfortably in your hand and pocket. The 1.26-inch TFT display is bright and easy to read.

Battery and safety

The 650 mAh battery charges over USB-C in about an hour. A 15-second heating cut-off protects your cartridge and the battery during use.
