went to harbour frieght and bought a briefcase style solar panel ..it will recharge 18 volt and 24 volt power tools..comes with a handful of attachments both male and female ligher plugs and clips for car batteries and a couple sizes of plug ins for those battery powered tools..the size folded is like 2 ft square and in use it unfolds and becomes 2 panels..everything sits inside a plastic case with a handle..cost is about $70 and in a no power situation will come in handy to charge alot of items..
