To watch a film on Netflix outside without WiFi using your mobile via the projector, you can follow these steps:

1. mobile internet: Make sure your mobile has a stable mobile internet connection.
2. streaming app: Open the Netflix app on your mobile and start the film.
3. screen mirroring or Chromecast: If your mobile and projector support Screen Mirroring or Chromecast, you can stream the film directly to the projector. Alternatively, you can use a cable if the projector has a corresponding connection.
4. power bank: Use a power bank to operate the projector as it does not have a built-in battery.

The quality depends on the brightness of the surroundings. The projector works well in dark areas, but the image quality may suffer in daylight.
