I recently purchased an SBIG ST-7E and I'm looking for a power cord compatible with a 12-volt battery. Then it got me thinking what I would do if something happened to the power cord I have now. Also, if I could find a lighter and longer cord that could be the next best thing. My issue is damaging the electronics with the wrong power cord. My question is would a third party power cord work with an SBIG or where to find a compatible cord that can run directly from a DC power source and skip the AC adapter?
