Recently bought an Apple iPad pro charger replica online. Hence didn’t find too much information online, I made a quick comparison between the original and replica. The replica not only charges the iPad pro 2020 but also some other USB-C powered laptops. However, for safety reasons probably only use as if there is no other choices.

It is also very difficult to tell the difference from photos / pictures shown from online shops. The only clue from picture is to look at the text under the pin carefully and double check if it has the Apple logo, or compare the text pattern with your original ones. Most of the time, if the deal is too good, the it is very likely to be a replica, in that case, better pay a bit more and get a used original one from trusted sellers.
