How many watts do I need for a laptop - and other solar power questions? - solar powered laptop

Hello,
I'm trying a very basic knowledge of solar energy to recharge.

Can you tell me:
How many watts is needed to run a portable power
How much, for example, to charge a laptop battery
As an MP3 player
Mobile: easy -> Smart range
a table lamp
Ceiling Fan
Floor fan
a window a / c

I just want to get an idea!

Thanks in advance!
