to add to TeacherRO.... attempt to standardize batteries, especially if you live in a location (like the West Coast of Florida)that you know is a target for severe weather... if you don't have a genset, a controller charger that works off a 12v cigarette plug is an asset... I chose the Sanyo Eneloop AA platform... items pictured all run off the AAs



the 12v power tap and the controller charger that works with 12v cigarette plug works well, the GoalZero is really not necessary
