Photos have surfaced which allegedly reveal a wireless charging coil for the iPhone 8. It's unclear if the component is for the smartphone itself or for an accessory.
Posted to Weibo by chongdiantou, the photos are purportedly sourced from an anonymous engineer. The part features a single-coil architecture for the charging coil and what appears to be a female Lightning port on the bottom for traditional charging. It's said to feature USB Power Delivery perhaps via a USB Type-C to Lightning charging cable which would supply up to 12V.
On the back of the component we can see some specifications: ● Output voltage: 5V-12V ● Output current: 0.6A-2A ● Output power: 5W-10W ● Efficiency: 70% -85% ● Compatible with WPC QI ● Product Certification: CE FCC Rohs ● Operating frequency: 110K-230K
It's said that Apple is testing a variety wireless charging technologies including inductive and magnetic resonance. It's still unclear which technology will ship with the new smartphone.
It's the supply side, not the phone side.
I have a similar bare bones component I'm working with and recognize it. Some of the circuitry is different and the connector isn't microUSB but it is pretty close.
