Like any device, and especially those you take with you while traveling, portable projectors need to be simple to set up and use. You don’t want a complex interface or lots of buttons, nor a lens that requires ages to warm up and cool down. Portable projectors work best when they just come out of your bag and turn on near instantly at the press of a single button.
Here we get to the connectivity part. Because in this day and age, no device works well if it works alone. Portable projectors are no exception. They should pair with your smartphone, tablet, and laptop. They must be able to go online so you can access everything from company presentation materials to Netflix.
Thus, good portable projectors have Wi-Fi integrated, preferably dual channel 2.4GHz/5GHz. With wireless connectivity, the projector isn’t just a simple light thrower but a smart device that puts up a world of info and content up on the big screen for you, wherever you may be.
