For the OP's question, define your INCH event.
To me, an INCH event is where things are really messed up and quite possible that supporting infrastructure is already gone or in bad shape. Meaning, would there still be a need to charge a cell phone? Carrying a few extra batteries for a flashlight is doable depending on supposed INCH event.
INCH event = Current conficts in North Africa, Middle East, and the Ukraine that is resulting in mass exodus of refugees to Europe. Refugees, once they're out of the conflict zone, will have access to mobile networks with the purchase of a local SIM card.
From what I have seen in the news pictures, the refugees are carrying any combination of casual backpacks, medium size conventional suitcases, and/or large cloth-bound bundles (I'm assuming regional carry technique).
