MP4 Powerpack – LiPoly Charger Hack – Part 1!
In my last travel to São Paulo, i bought a MP4. It’s a “MP4 with 1GB internal flash, SD expansion slot, Aux. Input and… FM radio“.
It’s a great gadget, and now it’s my iPod best friend. The only issue is that the USB mini B port in the back is for data access only. Don’t charge the battery !!! Bad design, bad…
I don’t understand why the hell they make a device like it without this primary feature, but i understand that it’s a great opportunity to hack it!
Let’s dissect it:

First items to highligh:
- 1700mAh Polymer Lithium Ion Battery (LiPoly);
- TPS61032 Boost Converter;
