ASUS ZenBeam E1R mini projector redefines portable entertainment. It features USB Type-A port connection for both Android and iOS devices and also automatic portrait projection* mode that lets users change the projector’s orientation while in use so they can easily enjoy social media content and livestreams on a bigger screen. And there’s no need to tinker with settings ― because the black sidebars are automatically removed as the projected image smoothly transitions from horizontal to vertical orientation.
