I have a bunch of items that are powered by batteries. They are all 5V devices. Since I don't like batteries I built the box in the attachment. The connector above the power supply that has a cable attached is what comes out from the box. The connector standing on the PSU is what would connect to the cable coming out of the box. However, now I wonder if I mixed this up. Should I have reversed the connectors? It's some work to fix it but I rather do it now than after I have built all the additional cables that go to the props and replacing the battery compartment of the props with the appropriate connectors.
