Raspberry PI Power Answered

Hi, I have a 10v 80mA supply available from a serial device. I want to use this to power a Raspberry PI, however I need 5v and 2A. Does anyone have any tips on how I can get the power available from the serial device to power the microcontroller?

It will not work.
See, You have: 10V x 80mA = 0.8W
You need 5V x 2A = 10W
Your supply is underpowered by a factor of 13 even if we assume a DC/DC-Conversion-efficiency of 100%!
Get a decent 5V-Charger from your local shop. Cost about 2$.
