For the film buff in your house, this camping projector will allow you to enjoy a movie or video when the night is winding down at your campsite. The projector has a silicone side compartment to place your smartphone into and works by projecting the small smartphone screen onto a larger canvas such as the side of your RV or trailer. Corrugated cardboard means the projector assembles easily and quickly. The durable glass lens magnifies the picture up to eight times without any additional power source. The back pocket can house a charger and small portable speakers. This is a great little surprise for the RVer on your list. Pair it with a speaker for the ultimate cinema experience on-the-go.
