EOS R5 C powered via USB-C Power Bank

I've experimented a bit with powering the EOS R5 C using a power bank. A Jackery power bank with an output monitor works and can drive the camera well enough to do RAW at 60HZ. It shows that about 18W is being consumed.

I bought one power bank from Amazon that did NOT work and I bought another one that does work .

I stumbled upon an official Canon site that says "Third-party USB-C powerbanks with power delivery can also be used."

The reason the "not working" one from Amazon did not work is because it could not produce more than about 8W of power from a single port.

Re: EOS R5 C powered via USB-C Power Bank

By the way, I got off on a tangent getting the cost per watt-hour of a lot of things starting with V-Mount batteries, Canon LP-E6 batteries in various forms, raw AA style rechargeable batteries from battery sites, batteries that can jump start cars, batteries used for recreational camping such as the Jackery line, phone power banks, etc.

Many things cite their mAh which you should assume is at 3.3V although it is a fairly vague and useless spec.  The spec you want is watt-hours.  You can get things for $0.38/watt-hour such as many phone power banks.  The "working" power bank I cited above comes in at $0.65/watt-hour.  Raw AA batteries tended to be around $1.00/watt-hour.  V-Mount batteries tended to be around $2.00/watt-hour and Canon LP-E6 type batteries tended to be around $3.50/watt-hour.

R5c usb power requires USB PD with 9V at minimum of 3A (27W min).

USB PD power sources can supply different voltages, so need to look specifically for 9V. The specific voltage used is negotiated when USB PD power is applied.

Is this from your own experimentation or did it from from a Canon reference?

From online sources (such as Canon, B&H, so forth). Sorry I don't have a link references for you. I just kept my conclusions when I research this. Info, as you say, is not easy to come by.

I'll add, the R5c will ignore a USB PD power source if it cannot provide 9V. Current (A) though is drawn as needed and can be less than 3A depending on lens use (such as using manual focus).

I just checked my R5c on USB PD power.  With a manual lens, the camera is drawing 13W (or 1.5A).  I only have a manual lens (the Canon VR lens).

Yes.  I don't know the details of why but if the USB port isn't or can't supply enough power, the camera just ignores it and reverts back to the battery.  It appears that it can use only one power source at a time.

Just to add to the data points, I connected my R5C with my RF 100-500mm, set it to 60 fps with IS and AF enabled, recording to a CF card and the power bank would occasionally flash 18W.  It doesn't tell me any more specifics.  The rest of the time it would show something less like 13W or 16W.  I randomly assumed that would be the most power hungry lens.
