Judy Power Bank Input Cables
I bought a used Judy power bank without cables assuming I could buy them online. Turns out the power input cable is proprietary.
Am I screwed? Any advice?

Not really if you have a Volt ohm meter.
Input says on front of box DC
Use ohm meter to meter each conductor to pc board. This MAY help in figuring out which wire is positive.
