Hi - look, I've just registered and I've tried to post a query on the relevant board as prescribed in "getting started" - this is as close as I've been able to get. So Danny, maybe you being the moderator you can help me.
My query is a bit odd because I want to find out the description of the unusual power plug on the Vixia HF-R400. I got a charger unit on Ebay but the plug doesn't fit even though it's close (Chinese). So I thought if I could get the right description I might be able to pick up just a plug. Canon doesn't seem to describe it, and everyone wants to sell only the complete box and dice. I found the ground (-) of the external camera supply and the battery are the same, but not the V+, which has DC IN 5.3V printed on the camera, whereas the camera plate has DC 3.6V on it - the battery supply. I've actually attached a socket to the battery (no easy job) so it can be kept topped up with a 3.7V inverter running off ten AA 2500mAhr rechargeables (12V), which gives me about 8000 mAhrs for a reasonably small battery pack.
It would be better, however, to drop the battery altogether if possible and just use the external power socket. Do you know what type of circuit (regulated perhaps?) is in the camera to account for the above two different voltage requirements? It would of course not be as efficient to use the 5.3V input - only just over double the AA battery mAhrs with a suitable inverter.
Cheers
