How Does the Freeloader Solar Panel Battery Charger Work?
Freeloader solar panels can turn sunshine into energy that is used to charge batteries in mobile devices. Alternatively, Freeloader can suck power from a PC via USB and deliver the energy to a mobile device battery. Freeloader can preserve energy in its built-in battery. A fully charged Freeloader can power, for example, an Apple iPod for 18 hours, a mobile phone for up to 44 hours of standby time, or a Sony PSP for 2.5 hours.
