Solar Panel 175W polycrystalline

I have a 12v, 13 watt solar panel – right here is a link to the page http://www.batteryjunction.com/12vbrsoges.html – I really want to use this solar panel to link AC adapters. IM not sure exactly what to do and ways to make use of the solar panel. I wish to be able to make use of a batter charger, a radio, and charge a GPS if needed. – Thanks, Zoo
