What is the Yocan UNI Pro Box Mod?
The Yocan UNI Pro Box Mod is a universal, precision-controlled 510-thread cartridge battery designed for oil and concentrate vaporizers. Powered by an integrated 650mAh battery, it features digital variable voltage adjustment from 2.0V to 4.2V (in 0.1V micro-increments), a crisp OLED display screen, a 10-second preheat function, and patented adjustable height and diameter sliders to accommodate virtually any 510-threaded oil cartridge up to 11.5mm.
Key Problems the Yocan UNI Pro Solves
- Preventing Burnt Terpenes: Unlike basic 3-tier preset batteries that jump by 0.5V, the UNI Pro’s 0.1V micro-adjustments allow users to fine-tune lower temperatures (2.0V–2.5V) to protect delicate live resin and rosin terpene profiles.
- Universal Cartridge Compatibility: Recessed chambers often fail to fit wide or tall tanks. The UNI Pro solves this with an adjustable height slider and a rotary diameter aperture wheel fitting cartridges up to 11.5mm.
- Eliminating Status Guesswork: Small LED indicator lights leave users guessing battery life and resistance. The digital OLED screen provides instant visibility on exact voltage, battery level, preheat mode, and firing timer.

Yocan UNI Pro vs. Standard Yocan UNI vs. Kodo Pro
While the original Yocan UNI relied on 3 preset LED voltages (2.7V, 3.5V, 4.2V), the UNI Pro introduces a digital OLED screen and precise 0.1V voltage tuning. Compared to the ultra-compact Yocan Kodo Pro, the UNI Pro features a recessed drop-in chamber with a protective magnetic adapter ring, giving cartridges superior physical impact protection during daily pocket carry.
Optimal Voltage Settings Guide for Concentrates
- 2.0V – 2.5V (Flavor & Terpenes): Best for Live Resin, Rosin, and high-terpene extract cartridges. Delivers smooth, clean vapor with zero harshness.
- 2.6V – 3.3V (Balanced Vapor): Ideal for standard THC/CBD distillates. Balanced clouds with rich flavor retention.
- 3.4V – 4.2V (Dense Clouds): Suited for thick oil viscosity or users seeking heavy, dense vapor output.
Frequently Asked Questions & Troubleshooting
Q: Why is my Yocan UNI Pro flashing “No Atomizer” or blinking 3 times?
A: A “No Atomizer” warning or 3-time blink indicates a connection failure between the magnetic 510 adapter ring and the bottom gold pin. Unscrew the cartridge, clean the 510 magnetic threads with a cotton swab dipped in 91% isopropyl alcohol, ensure the bottom contact pin on the cartridge is slightly pulled out, and firmly re-attach.
Q: How do I turn on and operate the Yocan UNI Pro preheat mode?
A: Press the main power button 5 times rapidly to turn the unit ON/OFF. Click the power button 2 times rapidly to initiate the 10-second 1.8V preheat cycle (ideal for clearing clogged oil cartridges). Press the power button once to cancel preheat at any time.
