The Best Portable Solar Charger Reviewed by Wirecutter

" The BigBlue 28W USB Solar Charger produces the most power of any portable solar charger we’ve tested, and it has unique features that make it more versatile and durable, including three output ports (versus two on most other chargers), a weatherproof port protector, and an expansive but lightweight array of panels to catch every last ray of sunlight. Although other models come close to matching it in terms of power, the BigBlue is also smaller and lighter than other options with similar output, so it can more easily fit into a camping backpack, hiking daypack, or emergency kit." -- By Wirecutter Editor
