What capacity external battery would be needed for using the DC portion of this coupler?

I am not sure. I am using a Anker astro pro2 that puts out 12, 16, 19, and 5v usb. It works with a little wire adaptation.

I'm guessing that you're asking this because you want to have an extended battery life. The back of the AC adapter says its output is 8V, 3A. The specs for the Canon battery say 7.2V, 1800mAh. I haven't tested this but I'd think that you could hook it up to a car battery provided that you find a way of dropping the voltage to 7.2V. http://www.circuitdiagram.org/12v-8v-converter-lm7808-regulator.html is one way if you can build your own. Another option is to search Amazon for DC-DC Buck Converters (there are lots).

12 vdc is required, if you lose power the configurations stays, i recommend you to use 3rd party relay on the output and do not use the direct relay output

Prior to answering, I carefully reread the instructions. No where is this question answered or addressed. I simply don't know. Technical info from instructions:" Power requirements: DC Adapter: 9vcd, 500 mA. Sorry!

It requires a DC9V-DC12V 250mA. So you have a range of volts to work with, but a set milliamp. Good luck. Have fun.

As this is a single 12v dc 21 w globe you can use a low amperage fuse such as 5 amp. Hope this helps.

No external power required. Only needs a USB port with enough power. Most standard USB 3 ports should be adequate.

As far as I know this is designed for 12 VDC. You could just connect the + (red) and - (black) to 1 battery for the 12 VDC

Can connect to 110 electricity or use regular batteries. (Not rechargeable). Either works fine.

12 volt DC 500 ma or higher ( I use a multi output power supply that powers up to 16 cameras mostly)

You have to use an external 12v dc supply, not sure about the double pole ?

"Powered by DC 12V 500mA adaptor (not included)"So any 12v adapter, that provides 500ma (0.5a) or more will do.

It uses a 12 Volt AC/DC power adapter, 1500 milliampere (MA) output, with a POSITIVE tip (that would be the inside connection)

There is a DC power connector on the back - no provision to run off internal batteries.

You can connect it to any DC power source, I spliced mine into the Cig Litter wires that my portable DVD play plugged into. The IR transmitters with line of sight easily worked to the outside of my vehicle.

All of uniden cameras use an external small 110 v. power supply, NO batteries

I have a central switch that provides 12 V DC. This is the only it'll work.

I know it needs DC4.5V power adapter, and I think it's 4-4.5 mm in diameter.
