It's important to note that while the Portaflixx Pocket Projector is compatible with a wide range of devices, some devices may require an HDMI adapter in order to connect to the projector. For example, iPhones may require the "Lightning Digital AV Adapter - Lightning to HDMI" from Apple. However, for devices that are already equipped with HDMI, such as Fire TV, Roku, Chromecast, Apple TV, Laptops, Nintendo Switch, PlayStation, or Xbox, no additional adapters are needed.
