About the Yocan UNI 4.0 Box Mod
The Yocan UNI 4.0 Box Mod is the slimmer, screen-forward successor to the UNI 3.0, built to hide and power 510-thread oil cartridges in a 28 x 40 x 75mm body. A 650mAh battery drives a variable 1.8V to 4.2V output in 0.1V steps, with a 10-second preheat at 1.8V that counts down on screen and can be stopped early. Yocan recommends cartridges rated above 0.8 ohms, and two magnetic 510 adapters, one long and one short, come in the box.
Fit is adjustable in both directions: a rotating dial sets the chamber width from 8mm to 14mm and a button-activated slider sets the height for cartridges over 42mm. The 1.26-inch TFT color screen shows voltage, puff count, battery percentage and cartridge resistance, sleeping after about ten seconds to save power, and a quick reset clears the puff counter. Transparent windows on the front and back show the oil level, framed by a circuit-board motif and carbon-fiber trim in Yocan’s cyber-industrial styling.
Charging is USB Type-C at 5V/1A, roughly an hour from empty, with a 15-second draw cut-off, a one-hour auto shutdown and five-click power control. Compared with the UNI 3.0 it is narrower, swaps the three-theme 1.93-inch screen for a 1.26-inch TFT, and fits slimmer cartridges. Available in Black, Blue, Pink, Purple and Silver.
