In terms of the charging cable, it is MFI (Made For iPhone / iPod / iPad), so do not worry, it is entirely consistent with the original Apple cables and the load goes smoothly, on time allotted, you will see no difference. No quality at a discount, the cable is finished and holds up well, no worries. With their legendary RAVPower and serious, it is the concern of shelter (even though you have a concern, they are always there to answer the call and find a solution)
In short, do not hesitate seen the promo prices currently practiced.
