As long as your phone case + the depth of your surface doesn't exceed 30mm (1.18 inches), ENERQi can charge your device even with a phone case on! However, please note, that phone cases that hold cards (magnetic + metallic strips) and pop-sockets that create an uneven surface, can cause disruption in your charging. MagSafe iPhones are 100% compatible, but MagSafe cases may cause issues in charging. It is recommended to charge your iPhone without a MagSafe case on.
