Best solar power bank

Which solar power bank is best?

A power bank is a nifty gadget to have if you know that a wall socket or charging adapter won’t be available for some time. For example, when you go on a five-day hike over a section of the Appalachian Trail, you know that an electrical outlet will be a luxury.

But even regular power banks go flat and must be recharged to use them again. With no socket in sight to charge your phone or power bank, the best solution is to hook up your gadgets to a solar power bank.
