Recharging the Omni 20+:
The Omni 20+ can be recharged using several methods:
- USB-C Input: Connect the included 60W USB-C cable to a compatible USB-C power adapter (not included).
- DC Input: Use a compatible DC power adapter (sold separately) to charge via the DC port. The Omni 20+ supports a wide voltage range.
- Solar Charging: The Omni 20+ can be recharged using compatible solar panels (up to 45W, sold separately).
- Car Charger: Recharge from a 12V car power outlet using an appropriate adapter (sold separately).
Full recharge time is approximately 3 hours with a fast USB-C charger.
OLED Display and Menu:
The OLED screen provides critical information about the device's status and operation. You can navigate the configurable menu using the buttons next to the screen.

- Status Icons: Indicate active ports (AC, USB-C, DC, Wireless).
- Power Input (watts): Shows the power being drawn into the Omni 20+.
- Power Output (watts): Displays the power being delivered to connected devices.
- Battery Percentage: Current charge level of the internal battery.
- Battery Temperature: Internal temperature of the battery.
- Time Remaining: Estimated time until full charge or discharge.
Pass-Through Charging:
The Omni 20+ supports pass-through charging, allowing it to be recharged while simultaneously charging other devices. This functionality works with the AC outlet, USB-A ports, and wireless charger. Note that pass-through charging does not work simultaneously with the USB-C and DC barrel ports for input and output, as these share circuitry for charging the Omni 20+ itself.
Maintenance
Battery Care:
- To prolong battery life, avoid fully discharging the unit frequently.
- Store the Omni 20+ in a cool, dry place when not in use.
- If storing for extended periods, maintain a charge level between 50-70%.
- Perform a full calibration (full discharge then full charge) periodically, especially if battery readings become inaccurate.
Cleaning:
Wipe the exterior of the Omni 20+ with a soft, dry cloth. Do not use harsh chemicals or abrasive materials. Keep ports free of dust and debris.
Troubleshooting
- Device not charging:
- Ensure the Omni 20+ is powered on and has sufficient charge.
- Check cable connections and try a different cable or port.

- For wireless charging, ensure proper alignment and that your device is Qi-compatible.
- Omni 20+ not recharging:
- Ensure the charging cable and adapter are functioning correctly.
- Verify the power source is active.
- If using USB-C or DC input, ensure no other input is attempting to charge the unit simultaneously.
- Perform a battery calibration if the charge percentage seems inaccurate.
- OLED screen not displaying:
