In a nutshell

USB-C PD source delivering 5V/5A, 9V/5A, 12V/5A, 15V/5A and 20V/5A profiles (100W), powered by a 9 to 24V battery, wired in XLR4. It is clear that this battery must be able to provide at least 110W of power, to take into account the inevitable losses. Two versions are proposed: vertical input and output, on the same side, for use in the bottom of a bag; horizontal input and output, opposite, for reduced vertical space.
