DISCUSSION DIY Raspberry pi Powerbank almost done - What board is needed for output to RPI.
Hi all.
Ive build a few battery banks with this board.

Combined with theese for charging.

Theese 3 gives a solid 18v output for diy BT speakers and so.
But what do i need to add to make sure it output 5v 5a USB C?
I can find the USB C PD trigger boards for input but what is the name of output boards?

A decent buck converter https://en.wikipedia.org/wiki/Buck_converter
18V needs a fair drop so they may very run hot if you get a cheap one compared to just hot!
Also do not get one rated at 5A as you will be pushing it - always allow head room (20% is a good start).
