Komodo power draw vs battery run time

[Zak Ray]

A B&H staff member lists Komodo's power draw as 45 watts (in the Q&A section).

My understanding of the power draw calculation is: (watt hours) / (run time in hours) = watts. Phil Holland's battery FAQ suggests we should get 2.2 hours runtime from a BP-975, which is roughly 54 watt hours. By my math, that's closer to 25 watts.

What am I missing?

B&H knows nothing

I've been on the beta cam and power things were in flux for sure during that time. Also I had no knowledge of how long the camera would really run, which is why I tested everything. However! There is a manual now.

In the manual official word on current firmware and production models is Komodo is 37 watt draw per hour. Which is a typo and deeper within the manual it states 27 watts, which I believe to be correct-ish.

I'm certain with various things toggled on and off you can add or subtract potential from the draw, WiFi comes to mind. Same for any camera with features like that.


Generally from my measurements and some discussion with some peeps at RED I average around 25 watts or lower and it can draw up to likely 37 watts. Betting the manual will reflect something like that once there's a better way to word it.

Thanks much Phil, very helpful!

I agree completely with Phil, I have seen an avg amp draw of 3.1a @ 7.4 volts on mine so that works out to be about 22-23 watts. This power draw seems to not be affected by the Komodo being idle or recording.... I think RED published that 37w figure to allow them some breathing room if the power did spike.
