I try to figure out how to provide my camera with enough power during video shootings and I have purchased a dummy battery with USB-C power adapter to connect it to power bank, but when I connected it to my camera nothing happened.
I think its because of the output voltage difference:
Powerbank USB-C has 5V;
PD Adapter needs 9V-20V;
I have also tried to search for a power bank with 9V output but couldn't find anything.
If someone uses such adapters in real life, how do you power it? What power bank/power supplier should I consider to buy in this case?
