To use my comunication devices and cameras for 24 hours while beeing on the road I bought a Sherpa 100AC. But like my other working stuff the new power bank from Goal Zero have to work perfect also in dusty enviroment and in condition where it can get punches and scratches. Therefore I have tested some rugged cases and travel bags and tried to find the one which protects the expensive stuff most. For me it is the SN Anti-shock GoPro HD Hero Case (UPC/EAN/ISBN_4894462253854). It is not much bigger then the power bank, have additional space for cables, power adapter and the manual, is stable and lightweight at the same time. The only detail I had to individualize had been the foam mat cause the one for the Hero logically will not work for the Sherpa. But you can find a lot of cheap sound absorbing nub foam matt on Ebay.
