This rechargable power pack could output any voltage at any amperage, up to that used by the highest-usage cell phone. It would have an adaptable clamp to attach to the outside of the phone and include a number of wires, each which could be set to a certain output or output pattern. The clamps and power
leads would be configurable to fit common phones, or be user-configured for new settings. It would come with a variety of plug-in adaptors, and have a piece of plastic the user could bend to fit a plug.
A wiki-style web site would list necessary configurations. It would be powered by standard batteries, a hydrogen cell, an AC/DC adaptor, or a solar panel. Finally, freedom from the lock-you-in battery selling bastards!

Sharper Image sells a crank up flashlight that also charges almost all cell phones. There is a battery company that sells one that does laptops and cell phones. |

Sounds obvious, but I haven't seen anyone making such a thing, so [+]. I've wondered in the past if I could use the NiCad/NiMH packs radio-controlled cars use, with a voltage converter to power all the electronic gadgets I carry with me these days. |

Presumably, it would have its own back-lit LCD and keypad to allow you to enter the appropriate parameters. |
