Your phone is your flashlight, map, radio and lifeline, and it dies fast in an outage. A power bank stores enough for several full charges, and a small folding solar panel refills it during the day. Wirecutter's solar charger pick, the BigBlue 28W, is light and folds to the size of a book. The Anker 20K bank has a built-in USB-C cable and enough output for a laptop. Charge the bank before a storm, keep it at room temperature, and top it off every few months.
