A:AnswerThe cover cannot be very thick in order for you to get a charge. I have a thin Under Armor case and mine works well - it has to be a flat case with NO popsocket.
A:AnswerIf the case is simply a protective case, as long as its back panel is no thicker than 3mm wireless charging should work fine. However, if the back panel is thicker, or if the case contains a battery or other metal, it may prevent the phone from wirelessly charging.
A:AnswerNo, it requires a phone with Qi/Wireless charge capability, which iPhone 7 does not have. As far as Apple iPhones go, you need an iPhone 8 or above currently.
A:AnswerNo, only iPhone 8, X, XS, XS Max, and XR are currently supported. iPhone 6 does not have wireless charging capabilities. Good rule of thumb is that only glass backed phones can do it.
A:AnswerMorphie says it is designed for Apple and Samsung phones. Key requirement is that the phone be Q1 enabled. I am using it with an Apple XR, works great, love it.
