Powering equipment with a plug lead
Devices that ship with a male DC plug cable but no matching power supply lead can be wired directly to a 12V source.
Bench power supplies and batteries
Add a standard female jack to a battery lead or lab power supply that only has bare wire or screw terminals.
Repairing or extending a power run
Replace a damaged female jack or extend a cable run without soldering, using the screw terminal side.
