USB wiring connector
USB phone chargers and battery banks are an excellent source of 5.5V power which can be very convenient to use for miniature lighting. I have a range of USB sockets that you can attach to your 5V mini house wiring. Choose depending on the type of USB cable you wish to use, and the angle you want to have it meet the house wall.
USB-A (the old style chunky ones) - flat or 90 degree upright
Micro-USB (matches older phones, etc) - flat
USB-C (current generation phones) - flat or 90 degree upright
USB cable not included, shown for illustration only.
This is a DIY wiring component and you will need to solder the connections to your house wiring.
