The solar powered MP4 player charges in sun, normal daylight and artificial light. As well as a 4GB internal memory the MP4 player comes with an AC adaptor or you can recharge it using a USB port.
If you need more than the 4BG memory you can expand the memory by using SD mini cards, in the built in SD-card slot.
Use the MP4 player abroad, out walking or running without the worry of losing power and needing new batteries, just ensure the solar panels face the light for a constant re-charge.
Compact and well built, versatile charging makes this MP4 player a great holiday companion too.
