If you want to enjoy large pictures anywhere, get the BenQ GV1. This compact projector has the size of a water bottle, and it has an integrated battery. When fully charged, this battery lasts for 3 hours, so you can also watch a movie when there's no power socket nearby. Store the projector in the bag and bring it with you to your friend's house. Thanks to the integrated WiFi receiver, you can wirelessly stream videos from your smartphone or tablet to the projector. You can also access the internet or Aptoide, which allows you to download apps. A push of the button changes the projector into a wireless speaker. This way, you can stream your favorite songs to the integrated 5-watt speaker using Bluetooth.
