I have a similar requirement. I would like to use this for video recording in a race car. I'm thinking of just powering this via an external battery pack to avoid having to introduce more variables (and potential issues) into the race car wiring. I have been reading some of the messages on this forum and also saw that the recorder can use a PSP power adapter.
So my question is would something like this work? Its a 4800mAh external battery pack for a PSP.
