Ok, I've done a little research and math in the meantime so please tell me if this is correct.
Watts = Amps x Voltage
So the camera power supply is 30W at 12V or so
So according to that formula the max Amps required for this camera is 2.5A.
When powered by the 7.2V canon battery at 2.5A that should draw 18W's or so
The feel world 279s monitor draws 18W's and is powered by a 7.2V battery. Which means that the monitor may need 2.5Amps as well.
So in total the max wattage and amps needed is 36W and 5A's from a 7.2v supply
Now the Swit 8972 battery spec's say that the battery can output 45W and 6A in total with 30W and 4A coming from both the pins and pole tap. So should this be more that enough to power the cam and monitor or am I overlooking something here?
Im going to assume the amperage on the dc output from Tom Antos's monitor wasn't enough to power the camera.
What has confused me though is another youtuber has recommended the powerextra multifunctional battery which is only $22 that has multiple outputs, however the dc out only supplies around 1 Amp yet he seems to have no problem powering the camera at 4k raw dci. Will this be a safe to use on going I wonder?
