A well thought out kit for alternative electrical power.

A hand crank might also be useful to power a cell phone when all else has given up its last electrons.

i.e. such as the Freeplay Energy - Freecharge (12v charger)

It will give out about 6-10W - I have even powered a 6W LED Lamp through a 75W inverter with one, along with Mobile Phones, radios etc. Making a phone call on a cell phone just require someone else to keep turning the crank.

The portable power products from Powertraveller are also quite handy.

I have also come across a small scale (240 Whrs) LiFePo4 battery solar charge regulator which has recently interested me as well.

This has certain advantages over SLA batteries, i.e. can be fully discharged not just to 50% capacity without damage and greater number of charge/discharge cycles i.e up to 5 times more.

The 3Kg weight would make it into the luggable weight range.
