Here are some key points and recommendations for choosing a docking station when live streaming on an Apple phone:
Interface requirements

Video output interface: Live streaming usually requires projecting the phone screen to a computer or other display device for monitoring or large-screen display, so an HDMI interface is required, and it is best to support 4K 60Hz resolution, such as Belkin 7-in-1 docking station and Baseus 5-in-1 docking station, which all have HDMI interfaces that support 4K 60Hz.

Data transmission interface: The USB interface is used to connect devices such as mice, keyboards, U disks, and mobile hard disks. If you need to connect external cameras, microphones, and other live streaming devices, it is recommended to choose a docking station with at least 2 USB-A interfaces and a transmission rate of 5Gbps or above, such as the Y-EARKOOR 9-in-1 USB-C multi-function docking station, which has 3 5Gbps USB-A interfaces.

Network interface: Live broadcasting requires high network stability. An expansion dock with an RJ45 Gigabit Ethernet port allows Apple phones to broadcast live through a wired network to ensure network stability and speed. Y-EARKOOR 9-in-1 USB-C multi-function expansion dock and Baseus 5-in-1 expansion dock are equipped with Gigabit Ethernet ports.
Audio interface: Some expansion docks have a 3.5mm audio interface, which can be connected to professional microphones and headphones to achieve better audio acquisition and monitoring effects. For example, the Y-EARKOOR 13-in-1 expansion dock has a 3.5mm audio microphone two-in-one port.
Charging interface: Choose an expansion dock with a PD fast charging interface to charge the Apple phone during the live broadcast to avoid insufficient power on the phone. Generally, the PD 100W charging power can meet the fast charging needs of most mobile phones, such as the Y-EARKOOR 8-in-1 multi-port converter equipped with a PD 100W charging C port.
