iPod jump leads
I don't appreciate carrying one device with full batteries and one with flat ones. | |
My poor little PDA's batteris are about to die, and the charger is at the other end of the country. On the other hand, I have an MP3 player in my bag with a good 18 hours of battery left in it. I know it won't power my PDA for that long. I know it's at a different voltage. But I don't think those are
insurmountable problems. All I want is a set of jump leads, so I can power the PDA from the batteries in the MP3 player. How hard can it be?

So you want an adapter to allow you to use x battery in y device. Well, it will be different for almost every x and y, because of voltages and amperages. Maybe a "magic box" with transformers [edit: resistors?] in it for common voltages and amperages would work - but only for common amperages and voltages. |

Much like the oft-mooted DC power supply for homes, this is really a problem of standardisation. My knowledge of electronics is not what it should be, but matching voltage and current (or "amperage" if you prefer) should be fairly simple (though not with transformers [roleo], they pass through AC but filter DC). The main problem I see is connector standards. It would be nice if manufacturers sold boxes shaped like the relevant battery that had 9V PP3 connectors dangling out of them. In an emergency you could always buy a PP3 battery which would then get converted by the box into a simulation of the real battery. But that's another idea. I call dibs! |

Whoops, sorry about that. Ya' learn something new every day. |
