which, believe me , is quite frequent in the third world dump that I live in)
I want to use it for charging my phone and laptop and to run 2 8W CFLs.
Pic somewhat related , but I guess I'll need a bigger battery and a heavy duty charger and invertor to get more juice outta it and to run it for a longer time.
Also , I'm thinking about cutting the costs , if I could get my hands on some cheap deep cycle batteries.

Suggestions ?

Can I add some mechanical crank system to charge the battery in case of a prolonged failure ?
