FreeLoader Pro Solar Power Charger
With an integrated battery, the FreeLoader Pro promises to fully charge in about eight hours in sunlight. More importantly, its manufacturer promises the solar cells will continue to work when its overcast and during poor weather conditions. In cases where you need to charge the FreeLoader Pro's battery but it's not possible to leave it in sunlight, it will fill itself up in about two hours when connected to a USB cable. When an iPhone (the device is compatible with all iPhone models) is connected to the FreeLoader Pro, it takes about an hour and a half to fill up its battery.
