I cannot pass-through charge between the barrel port and the USB-C port Follow
Both the barrel port and the USB-C port on the Omni 20+ operate on the same circuit, and can therefore not pass-through charge between them or operate at the same time. Pass-through charging on the Omni 20+ only functions with input from the USB-C or barrel port, and output to the USB-A, Wireless, or AC ports. For pass-through charging to a laptop, we recommend inputting from the barrel or USB-C port and outputting from the AC port.
