“We bought this projector to use with our teardrop camper. We could run everything off of the 12V plug on our camper, so there was no need for a noisy generator or outside electric. The camper's battery charges from solar, so this is perfect for when we are boondocking or if we take our camper to a tailgate party. The picture quality was very good at night and the sound wasn't bad from the built in speaker. We did use a Bluetooth speaker, which has better sound quality. It was very easy to get everything connected.”
