Mikroelektronika present you a new product- USB Charger board. You have probably charged your Li-Ion or Li-Poly batteries using large and heavy adapters, or some more advanced electronics. But those days are over.
For a price of one battery, you can have a fast and reliable charger with MCP73832 charge management controller, powered directly from USB port (and we all know USB hubs are everywhere these days).
Board is small and barely bigger than the miniUSB connector, so it can be easily integrated in your prototype or final device. Make sure to visit the board webpage to for more details. Also you can view, i made board for usb charger with MAX1811.
