System and apparatus for charging an electronic device using solar energy

This invention describes a portable device designed to charge electronic gadgets using solar power. It features two connection points: one for a solar panel to gather energy, and another for your electronic device. The device can either store the collected solar energy in its internal rechargeable batteries for later use or pass it directly to your gadget as it's being generated.

Why it matters: Filed in 2005, this predates the widespread availability of efficient, compact solar panels and high-density rechargeable batteries. Advances in both solar cell technology and battery chemistry since then make building a practical version significantly more feasible.
