IN DETAIL:
==============================
Because of the high price of the original cables and adapters Apple I, I looked at an early stage by appropriate alternatives. Unfortunately, copies of other manufacturers are all not very good. If you want to only load his equipment is usually sufficient for an copy, but for the connection of accessories, PCs, etc., it has not been passed. This is probably because that the new port is not just plain old contacts will be redirected to new, but have the plug on its own electronics. The plugs have forwards its own chip of the signals depending on the connected equipment different. This complicated function has not hammer out with me only the original Apple. Until now!
When I discovered the adapter from Ravpower, I immediately slammed and was pleasantly surprised: The cable is working with me on all devices and parts and accessories exactly like the original. I could not detect any difference so far.
CONCLUSION:
==============================
Without any limitation to recommend. In the function 100% identical to the original of Apple and also a significantly better price / performance.
