Nokia N70 model does NOT support battery charge through miniUSB port.
You can asemble a 2mm power jack to a usb port or buy this LINK

Hope this helps.


You're absolutely right. Wasn't aware it was a N70. For a cheap usb charger solution: http://www.dealextreme.com/details.dx/sku.23870

 
Dear Medianoche,

I want to asemble a 2mm power jack to a usb port,
Please suggest which node of USB port (1,2,3,4) is for power supply.
Also suggest that can I directly use the power supply or I have to put some resistor in between.

It may look odd, but buliding some useful thing from scap / spare is real fun for me.

Regards,
Nilesh.
