For Noopl to be Apple MFi (Made for iPhone) certified, it must connect properly with the iPhone when the phone is not within a case. While some some cases prevent Noopl from making a proper connection to the phone, there is a solution.
A "Lightning extender" is an accessory (often ranging in price from US $10–$13) which can reach through thick cases and then allow Noopl to connect. Here is a picture of one being used to connect Noopl through a thick Otterbox case:
