If you check some of the portable battery chargers, they have a 3.5mm jack for hookup to a car cigarette lighter accessory. You can use this jack to
insert voltage from a solar panel. Maybe somebody has a readily available solution, but that is all I have.

Darn shame they don't charge AAA, AA, C & D cells. Anyone know of a quality solar charger for common rechargeable batteries?
They can power a charger you already have. Check the website, they have all the adaptors.
