pocket projectors, also known as pico projectors, are getting brighter and more capable. Although they're still no match for a high-lumen home theater projector, these small wonders are unsurpassed in terms of size and ultra portability. The original pico projectors had no built-in intelligence to decode files. They relied on a connected computer or video device to play content.The new crop of pico models has internal storage, or they let you plug in a memory card or USB drive and embed decoders for a variety of entertainment and office formats, so you can travel unencumbered by extra hardware.
If your audience numbers in the single digits and darkness becomes the viewing room, a projected image can make for a more dramatic presentation than crowding heads around a small TV screen. Also, because the light source in all pico projectors is one or more LEDs, the projection lamp will typically last the life of the projector.
