VTEK Lightning Extension Cable for Lightning devices is a next-generation extender cable for new iPhones (5 and later).
This 6 feet longth male to female lightning extension cable is compatible with all new lightning-equipped iPad, iPhone and iPod models (like iPhone 5/5s/5c, iPad Mini, & more), where extra distance is needed.
It was designed to give you extra reach when you need it, let you keep your case on while you connect to a variety of accessories, and keep your device in your hand when connected to speaker docks or other audio systems. Please check if your case has the right size slot which can fit the size of this cable (Male end size: 1.3*1*0.7cm)
There may have "This cable or accessory is not certified and may not work reliably with this iPhone" such message came out while disconnecting with your original cable at the first time use, but this will not influence the normal working of this cable.
