The solar backpack is your regular bag or backpack, equipped with a built-in or detachable solar panel charger. This charger, roughly the size of an iPhone, harnesses sunlight and converts it into power for charging our gadgets.
There's a common misconception that solar panel backpacks are costly, but that's not true. This solar panel charger can easily attach to your backpack using Velcro. While some other solar chargers might be pricier, they often offer additional features for the higher cost.
