I recently bought a pop-up booth for doing outdoor craft shows. The inner walls of the booth are a silver/gray color, which makes for a somewhat dim appearance. I have a light setup for indoor shows, so I'm considering using it inside the booth. I would have to power the lights with a portable generator with a rechargeable battery (gas generators can't be used). My question is...has anyone used this type of generator? If so, how useful/effective are they? What are the specs that I would need for the generator to supply power all day (about 8 hrs)? My light setup has 8 lights which draw 10 watts each. TIA.
