Charging & Data transfer - no problem. No error message that the cable would not be certified.
Just as I expected it, because it is the manufacturer so Apple MFI certified :-)
The cable has a diameter of about 2.5 mm and weighs just 16 grams. There is a total (incl. Connector) about 94cm long, without connector about 89cm.
I have received the RavPower RP-LC01 as a test product and recommend it.
Processing continues in my opinion fully in order and as it also works very well, it's a good and especially cheap alternative to the expensive original.
