An ice fishing box to house my ic-7000, an atu, a battery pack. Very crude but solid rack made of pine board I had laying around. This is cobbling of the best sort.

How much RFI do those power banks spew out?
USB PD only goes up to 3A at 15V. That’s not enough current to run a mobile radio.
A small LiFePO4 battery is a much better choice as it will supply a stable 12.8V without any switch mode supplies.
I agree. Never measured the RFI since it usually replaces a cheap switchmode power supply from mains, so can only get better.

@Eheran This is incorrect. USB PD does 20V 5A (100W) with the common 3.0 version. 3.1 increases that to 240W using higher voltages. https://www.usb.org/usb-charger-pd
Most radios won’t run on 20V or higher. At 15V or lower, USB PD is limited to 3A.
If you wanted to get 100 watts, you would need a buck converter to step 20V down to 13.8V. Now you have two switch mode power supplies producing RFI.
