Designed for online broadcasters and TikTok users, the Ulanzi ST-18 dual phone holder is useful for those who need to use two devices at the same time, one for broadcasting and the other for telecommunications. The ST-18 helps enhance your videos by providing dual flash shoe space for your microphone and lamp, while the stand has a 1/4 "-20-inch thread and Face interface on the bottom. If the devices are placed in a portrait (vertical) orientation, you can charge while shooting because the charging port is not blocked.
