[Swansea Hackspace] New Project - Powerpack for a laptop

[Richard Morgan]

Hi All,
I'm looking to 'make' a battery pack that I can use for travelling and
charging up my kit (iPhone, iPad, Mi-Fi and laptop) - laptop is a priority.

This is the kind of thing
http://www.mophie.com/shop/mophie-juice-pack-powerstation-duo-smart-phones-tablets
but
it won't power a laptop.

Need it to:
- Fit in the backpack (i.e. not too big and heavy)
- Fast charging for the stuff I charge off of it via USB
- Indicator to show how much power is left
- Able to charge a laptop (ideally able to provide power to the laptop)

Has anyone come across a project page that talks of doing something similar?

-- 
Kind regards,

Richard
