Original charger from the dealer "Brilliant Comms"

The unit supplied to me it almost certainly is not is a cheap imitation.
(It's all about the white model, in which you plug in the cable on the side and can read in the photo the Samsung logo! Not colored things with the slightly smaller plug!)

Optical:
The case is exactly the same with the picture. The corners are rounded, all plugs fit. The cable has a plastic band. Only the side is printed with Cyrillic letters. This series was probably produced for the Russian market. According imprint 2 A.

Functional:
The charging time seems normal. Heat generation is less than with my original 0.7A charger with welded cable. If plugged into an outlet, but no phone is connected, making it extremely quiet sounds. I think that's not serious. When you load it is completely silent.
The cable I have tried without an adapter plug on the PC. Here, too, the loading work (probably more slowly because only a PC usually between 100 and 500 mA supplies). The use as a data cable worked fine.

Conclusion: Can I buy from "Brilliant Comms" without hesitation. Use as battery charger and data cable without any problems.
