The Surviva is a rugged 12000 mAh power bank built for camping, hiking and load shedding kits. It charges from a wall plug through its micro USB port, or slowly from the built-in solar panel when you are away from power; a green light shows when it is solar charging. Two USB outputs let you charge two phones or devices at the same time. A twin LED flashlight on the end gives 60 lumens, and there is a built-in lighter for lighting a fire or stove without matches. The body is rubberised for shock resistance and rated IPX4 against splashes, and a carabiner lets you clip it to a backpack or tent. A battery level indicator shows the remaining charge. The solar panel is a backup: charging fully from the sun takes a long time, so top it up from USB where you can. In the box: power bank, carabiner and micro USB cable.
