The Allocacoc Lightning cable charges and syncs Apple iPhone, iPad and AirPods models that use the Lightning port. It is MFi certified, meaning it is made under Apple's Made for iPhone/iPad licence and uses the approved Lightning connector, so it works reliably with iOS updates and does not trigger 'accessory not supported' warnings. The other end is a USB plug for a wall charger, car charger, power bank or computer, including the Allocacoc USBcube chargers. It is finished in grey to match the Allocacoc range. The exact length was not stated in the information we had; please check the packaging if you need a specific length.
