This is a 12 volt test box i built using a small pelican case i had in the shop. I bought a dee cycle battery from Batteries. Plus and added a cig. Plug , gator clips, and speaker level inputs. It works great for setting flash patterns while installing lights and showing customers different flash patterns. I use it at most of the shows we go to for demonstration if lights and to charge my cell phone (when 120v isn't avail.).
