I would like to see a general purpose DC-DC connector that could be used to hook up your car to other battery power equipment. It would be nice to be able to recharge your battery powered lawn mower / string trimmer / chainsaw without having to go through an AC/DC converter. In a perfect world it would be great to be able to share your juice with another car. This would come in really handy for places that you aren't familiar with or don't have great charging station coverage. Imagine your on vacation and your hotel doesn't have charging; borrow some charge from a fellow traveler. Or your on a road trip and see a fellow electric car owner stranded at a rest stop; slip them some of your charge.
