A: With the new OneFit™ feature on both devices, the connector will adjust up to an additional 4 mm in length. This length is compatible with most protective cases, so you don’t have to choose between thermal vision and safeguarding your device. We have not tested all cases, but have picked many of our favorites. The 4-mm extension will not complete a connection through the Lifeproof and Otter Box Defender cases. For iOS units, it is possible to use the following part from Amazon.com to connect through these cases: 1 Otterbox 8 pin Lifeproof Lightnin Dock Extender Adapter for iPhone 5 5 6 6+ (Black) (ASIN: B01D7F1OA4).
