Question about Samsung EP-DG950CBE

This is a standard USB C charging cable for Samsung devices. This fits the adapter that has a USB A port, or a standard USB A charging/data port.

With the newer Samsung phones, however, the adapters only have a USB-C port, so this cable would be necessary.

The newer cable would be this one:
Samsung USB-C cable (1m)

It's best to check what kind of port your adapter has, unless you just want to use the cable to transfer data.
