Thank you, dougwalkabout, it's really inspiring!
I'd like to add some more details on the kit, if nobody mind.
Regarding the connectors number optimization. Actually I've standardized about 90% of my devices on mini USB connector already. But I've decided to keep the most complicated phone connectors in order to be able help other people to charge their phones in an emergency.
The AA charger is retrofitted with 3 additional connectors and a switch, which allows to connect different cables for charging, discharging, and to use the box as a gender changer or for conversion from one connector type to another (mostly for my older power options, which rely on a larger regular size stereo phones connector. Also I've installed an ultrabright LED in it so it can serve as a simple but long lasting flashlight. The orange tape on the box is actually on the custom made plastic lip, one side of which is for clipping the box on the inner pocket of my vest (so it hangs under my left rib rather than on the bottom of the side pocket), the other side fits tight between the batteries and charging terminals, preventing possible slow discharge into the circuit. It's transparent, so it's easy to loose it without the tape.
The neodymium magnets in the kit take almost no space, but simplify a lot rigging the standard AA,AAA,C,D,etc cells into the batteries in series for a particular voltage (they are actually a magnetic closures for the jewelry, and have very robust tool-less wire mounting features). Also, theoretically, it is possible to improvise a rotary electric generator with them (never tried though).
With enough electrical power available at your disposal the nichrome wire can also be used as a precisely controlled heat source. For example: for fire starting, which is more gentle on the batteries than steel wool, bare wire, or pencil core methods; to boil water even in a zip lock bag; to cut, seal and glue plastics and styrofoam, e.t.c.
I'd prefer to reference my hard-cover books though, or a PDF file.
