Even as low-power components and fast and wireless charging take on ever more demanding applications and near-constant usage, the need for more power on the go seems limitless. Stored electricity has advanced from being something that lived in an AA cell to a backup source that can power entire homes.
As such, portable power sources have evolved way beyond little USB charging sticks to products that boast multiple AC outlets intended to compete with gas generators. Many are labeled "solar generators," although solar panels are sold separately and the battery-based sources charge faster when plugged into a wall.
Nonetheless, there are a number of products that can keep the juice going.
