The Lightning Audio + Charge RockStar makes it possible to listen to Lightning Audio while charging your iPhone 7 and iPhone 7 Plus. Enjoy music or talk through Lightning Audio headphones while you charge. Use the RockStar anywhere; at home, at work, in the car or on the go. The RockStar delivers power in to your iPhone/iPad, and only supports Lightning Audio. It does not support syncing or any other USB data, or similar protocol like Serial or UART. 12W pass-through charging powers up the iPhone/iPad at maximum speed. So whether you're listening to music, watching videos, using navigation, or taking calls, you can charge anywhere. The Lightning Audio + Charge RockStar supports up to 24bit 48kHz lossless output, and is compatible with the full ecosystem of Lightning Audio headphones. The RockStar will also support the higher power delivery required by premium or professional standard Lightning Audio headphones to deliver superior noise cancellation without the need for batteries or an additional power supply.
