After all, while a standard 3 cell MSI Wind netbook battery may only provide a few hours of run time for a laptop, it’s got enough juice to run a low power device like an iPhone for ages. So he cut open the battery and connected a USB port that can be used to plug in a USB charging cable.
The hack is not for beginners. It requires some soldering and a bit of electrical know-how. And to be perfectly honest, the end result is a kind of ugly mobile device charger/extended battery. But it certainly gets cool points. As you can see in the video after the break, the modified battery can still be used to power a MSI Wind netbook as well as USB gadgets
