For portable and travels I was looking for a solution to charge batteries for handheld radios. A powerbank with USB-C PD port and solar panel was already part of the equipment. So the idea was to have 12V output from the USB-C PD port with some milliamperes on power poles.
During an order at a local parts dealer I found a reasonable USB-C PD trigger module with solder pads (See [1]). A pair of power poles was soldered to the pads to connect the radio via its barrel connector.
The module allows switching the output voltage. 5V (red), 9V (yellow), 12V (green), 15V (light blue) and 20V (dark blue) are available represented by a specific color of the LED. In addition the default voltage can be set using the button. So this one was set to 12V per default. Charging a Kenwood TH-D72 uses about 300 mA which the module provides without dissipating much heat.
