Is it waterproof?
Can they be chained with each other?
They can be chained with each other using the buckles that comes with. But it is not possible to improve the power of the charge by using two solar chargers toghether. Each one has its own inner structure that can't be connected with another one.
Is this rugged enough to be kept folded in a typical backpack with other gear pushing against it without damage?
Of course it is very rugged, but please be careful to not over bend or scratch the panels.
Would it be Safe to charge 3 mobile battery packs/mobile batteries at once with this?
Might take a while but it has 4 usb connections.
Do all four panels have to get sun for one usb port to charge?
All the solar panels need to be exposed under direct sunlight, otherwise, the solar panels that are not exposed to the sun will become resistors, making it impossible to charge
Do the panels have auto-restart while in the sun?
Of course. It starts charging again the moment it produces enough output for the attached device to charge.
