Sony PC with 10.5V charger
the charger is marked as 10.5V 3.8A but measure with meter, it shows 11.5V I was plan to use PD type C, but some charger does not provide 12V so , I have to set for 15V, if the charger only top 12V, it will delivery 12V. then use a DCDC to switch down to 11.5V The first I used is this small one, but it turn out very hot at about 2A load. so a larger module is necessary: with thing connected in a 3D print box, it does not save me much room... So, what for?
