Getting Started

Initial Charge

Before first use, fully charge your UNI 3.0:

  1. Connect the USB-C cable to the device
  2. Connect to a USB power source
  3. Allow 1 hour for initial charge
  4. Display will indicate full charge when complete

Note: Subsequent charges typically take 1 hour or less.

Installing the Magnetic Adapter

The magnetic adapter connects your cartridge to the battery:

  1. Locate the 510 magnetic adapter (small disc with center pin)
  2. Screw the adapter onto your cartridge's 510 threading
  3. Tighten until snug—do not overtighten
  4. The adapter is now attached to your cartridge

The magnetic connection allows easy cartridge swapping without re-threading.

Adjusting Cartridge Fit

Width Adjustment (Top Dial)

The top dial expands or contracts the cartridge chamber:

  1. Turn the dial clockwise to expand (larger cartridges)
  2. Turn the dial counter-clockwise to contract (smaller cartridges)
  3. Range: 11mm to 16mm diameter
  4. Adjust until your cartridge fits snugly without forcing

Height Adjustment (Back Slider)

The back slider raises or lowers the cartridge position:

  1. Slide up to raise the cartridge (taller cartridges)
  2. Slide down to lower (shorter cartridges)
  3. The mouthpiece should be accessible above the device
  4. Fits cartridges 42mm and taller

Inserting Your Cartridge

  1. Ensure the magnetic adapter is attached to your cartridge
  2. Adjust width and height for your cartridge size
  3. Drop the cartridge into the chamber—magnet will hold it
  4. Verify the cartridge sits securely without wobbling

Powering On/Off

  • Turn On: Click the power button 5 times rapidly within 2 seconds
  • Turn Off: Click the power button 5 times rapidly within 2 seconds

The display will illuminate when powered on.

Voltage Settings

Voltage Range

The UNI 3.0 adjusts from 1.8V to 4.2V in 0.1V increments:

VoltageBest For
1.8-2.4VThin oils, maximum flavor preservation
2.5-3.0VStandard cartridges, balanced performance
3.1-3.6VThicker oils, increased vapor
3.7-4.2VVery thick concentrates, maximum vapor
