Probably won't be sufficient for a router, but it would charge a battery bank or phone pretty well (make sure it's angled 30 degrees south, and use a usb battery bank between it and the phone because the phone usually won't adjust the charging current up and down as clouds come over). For laptops, use a power bank with a laptop 19v output.
