An innovative approach to solar charging revealed in an Apple patent application published today (via Patently Apple) could make it more practical to power both MacBooks and iOS devices from the sun.
The voltage and power generated by a solar panel varies with the amount of sunlight. To turn the power supply into something that can safely be used by an electronic device, you need a converter or regulator to deliver the correct specs to the device, adding cost and bulk to the panel.
What the Apple patent describes is building the necessary power management circuitry into the MacBook, iPad or iPhone so that it can accept whatever power the panel supplies. This potentially allows for cheaper and more portable panels … Read more
