I have the Lightning Data cable compared to the original that came with the iPhone 5c upon delivery:
The model RP-LC01 of RavPower comes in a small cardboard box, which is internally equipped with a properly fitting for the cable blister. A short manual is included. Unpacked and placed next to the original, the cable from RavPower is about 10 cm shorter, which becomes hardly noticeable for me in the use. The cables themselves are, as regards the thickness and nature, visually almost identical. The Lightning connector and the USB connector fit perfectly and were tried by me on the iPhone 5c. Both the charge as well as the data transfer to the fold Lightning cable from RavPower as good and fast as the original cable. The casing of the plug is slightly greater in RavPower and makes a more stable impression, as well as the transitions between connectors and cables.
By following Apple products the cable from RavPower is compatible:
iPhone 6 / 5S / 5C / 5
iPad Air / Air iPad 2, iPad mini / mini 2/3 mini, iPad 4th generation
iPod nano 7th generation
Conclusion: in view of this much better price-performance ratio, it's definitely a good idea to pull the offer of RavPower into consideration if you need a new Lightning cable, because in addition to the very good price you will also find the lower shipping.
