I use this projectors previous model for my camping trip movies where I can hook it up to an inverter and don't care if it get's stolen. I sometimes hook my retron 5 up to it where graphics don't mean squat, but for the Switch... Honestly, you'll be able to play the games, but graphics wise it'll look like crap. With anything beyond backyard movies and old 8-bit stuff it looks liek you're watching a VHS movie through a screen door (look up "screen door effect").
