Main goal for me to use my existing powerbank which supports power delivery as power source for my router and ISP modem during blackouts. To achieve this I used power delivery trigger which I configure to trigger 12V from my powerbank (to power ISP modem) and mini buck converter that I set to 9V (for my router). For output connectors I used two pair of
2.1mm Barrel Jack's. I also make pair of dc-dc cables to connect to my devices. Obviously you can configure with any other configuration for example trigger 20V for your soldering iron, and set buck converter to 12V for something else. If you need two outputs with the same voltage you simply can remove buck converter from the schematic and connect two DC jacks to PD trigger.
Be aware about what output voltage/ampere value your PD powerbank/power supply can output so you can calculate what you can power with it. Usually you can find this information directly on powerbank/power supply itself.
