When you're on the road often to give presentations, the LG PV150G is just the thing you need. This mini projector weighs only 270 grams. Tuck it away in your bag and take it with you wherever you go. The projector has an integrated media player, so you don't need to bring a computer along with you. Connect a USB flash drive or external hard drive, and view your pictures, videos, and Office files. You don't need a socket nearby, because the projector has a 2-hour battery life.
