Arguably the most important. We mentioned smart capabilities in feature no. 4. But that’s just part of a connected portable projector. If you insist on getting a bargain basement product, you’ll soon find it doesn’t have Wi-Fi and Bluetooth, two specs routinely found on good portable projectors. With Wi-Fi and Bluetooth, connect your portable projector to a host of devices and apps to cast content onto a large format display. Play video and music from your smartphone, tablet, laptop, game console, PC, in-car entertainment system…the list goes on and on. Connectivity makes all that possible. As a related bonus, make sure your portable projector has good speakers (2W or more, dual 2W recommended). Combined with Bluetooth, that means the projector works as a standalone audio device for your music.
*As a side note, in some cases copy protection may prevent you from casting streaming apps from your smartphone to a portable projector via wireless connections. However, you can certainly watch streaming apps using a smart, app-enabled projector that’s hooked up to Wi-Fi, and also via streaming boxes like Apple TV or consoles (Xbox and PlayStation).
