Does anyone know the specs for the external power suplpy of adapter for the Dimage 7? I can assume 6V but how many Amps are required to activate the camera.

The voltage is less important than the amperage and polarity (I use a 5V 2A power supply, but others have used up to 7.2V with no problems).
You need at least 1.5A and probably 2A to fully power the camera. |

Some 6v external power supplies are inadequate to power the camera, particularly the newer models. Digipower makes an inexpensive adapter that's widely available. I'll check the actual and rated voltage on mine if you like.

My 6V / 2.1 Amps was ok for my D7, with the D7i, I have to set it to 6.5 V

I have the Minolta AC-1L intended for the D7's and it's rated @ 6V - 2A. 8)

Appreciate the responses folks. Now for the next question, I had a 7.2V 3600mAh battery...to be on the safe side I opened it up and took one of the cells out (it was RC battery that is made up of 6 individual C cells) making it a 6V battery, does that mean I have 6V 3600mAH or does it mean I have a 6V 3000mAh battery?
I am sure someone had done some electronics out there. I did this just to be on the safe side as Minolta says that 7.2 is the maximum it can handle. |

i made an ext. battery pack using Canon camcorder Li-on battery, which is 7.2 v 3600 mah. it can take at least 500 photos.
the digital circuit will regulate the frequency of the power automatically for the camera. so the 7.2 v here is not a problem. |

I'm surprised the Maha site lists a Lithium ion external battery pack for the D7i instead of NiMH.

But the battery pack with a higher voltage (within the camera's limitation) will last longer just because when the voltage is higher, the camera will draw less curent. |

IMO I think you're on the right track with the RC car battery. They are cheap, quickly recharged (ie 10-20 minutes) and quickly be swapped for a new set by just making a simple Molex cable adapter from the cells to the camera input jack. Plus they fit perfectly in a cell phone holder...
