I did take several close-up photographs (Macro lens) from the PCB, for my private collection.

UNIROSS UCU004 this is product of 2022, even so this OEM he is very familiar with Eneloop chargers, for a decade at least.

By taking apart my UNIROSS UCU004, I did notice that 5V USB mini & USB Type-C 5V input, both not using any pins related to Data.

This information inspired me so to add an third round barrel connector.
So to be able to use my generic 5V 2A PSU instead.

This pair of white connectors, they were removed from a damaged LED panel.
And today, this 5V DC add-on connection, it is also color coded
