I cannot pass-through charge between the barrel port and the USB-C portUpdated a year ago

Both the barrel port and USB-C port on the Omni 20+ cannot pass-through charge or operate simultaneously. Pass-through charging only works with input from the USB-C or barrel port and output to the USB-A, wireless, or AC ports. For laptop charging, input from the barrel or USB-C port and output to the USB-A, wireless, or AC ports is recommended.
