Yes, the USB voltage is 5 V and the device you linked is a 5V to 8.4V converter to allow a USB supply to provide voltages needed by camera.
Interesting, it sounds like the different brands may be compatible? Not sure how needed that Panny one is either way, i looked up the Case Relay coupler and even B&H has tons of different battery inserts listed from multiple brands. One way or another i think all the major cameras are covered from each brand.
My Sony A6300 can charge and operate the camera with power from the USB port. So doesn't even need one of these.Found an awesome product. The caveats, you have to deal with your hotshoe being occupied (or find another way to attach it), and you will have a cable present from your battery door (maybe it works in a battery grip too?) going to the adapter. Aside from that, you are only limited by the USB pack you can afford.
It's called the iFootage Electric Ray. It gives you a converter to attach the USB pack to, and a dummy battery to fit in-camera. Some USB charger packs are 30,000 mAh. I can't say for sure if every USB battery pack is the proper voltage for any camera, that's something to look into, but i think i will be getting one of these, and it makes the battery life issues of ML a little less a problem if i go that route down the road (Sony can already do similar).
Just thought anybody wanting a way to rig more battery life on the go might be interested. Below is the Nikon version listed on B&H. HERE is a video explaining it i found on YT.

"We've come prepared
Suspending all benevolence
You've bathed in arrogance
Our retribution we will bring
She flies on unforgiving wings
Your children in Heaven shall weep and grieve
As holy gates open and nothing leaves
So down the cattle chute you will move
And die for him who's died for you...
Blinded by our pride we've missed the signs
We now beg of you, Lord, hear our cries.
The scars you've made altered the plan
Our end will never be ushered by man
So down the cattle chute you will move
And the burden of Earth will be removed
You are quarantined to the abyss
With all life forms deleterious
You have lost all that you will ever lose
Your request to be saved by God, refused !"

AFAIK, there are USB-C specs that allow charging at up to 20 volts and 5 amps. Both power source, destination, and cable need to be compatible.I, for one, won't
Rather use the spare battery + USB type battery charger + USB power bank. At least, if the battery caches fire, I still am safe :-D
Also cheaper too.
There are 2 camera battery types. The 3.7v and the 7.2v. The USB is 5.0v, thus will charge the 3.7v type directly (via voltage step down circuit).
I mentioned that, highlighted above. But in my research recently i also read a lot of people claiming it's not perfect. Depending on the usage and the camera, there's apparently issues with not providing enough juice coming straight from the USB pack.
I made my own and have been risking it in three A7 series bodies for about 2 or 3 years now. So.. Ya, I would.
There is nothing technically challenging to connecting a load of NiMH D cells to power a simulated battery in your camera, But it certainly limits the flexibility and portability of your camera with it. And yes, there are certainly risk doing so that a UL or CE certified Li-Ion battery protects against by insuring there current and heat fuses.
It's not conventional signal USB, but Power Delivery (PD) USB. You won't see it in the general market/shop or airport.AFAIK, there are USB-C specs that allow charging at up to 20 volts and 5 amps. Both power source, destination, and cable need to be compatible.I, for one, won't

He use NiCd to supply power to the camera through the dummy battery. There's no Li inside camera so I think his setup has no risk at all.

Yes
Hope some one builds it. Some Apple iPads can use this feature with their charger and USB-C to Lightning cable. A power bank would be nice. {example: iPad Pro 12.9", USB-C to Lightning cable, 29W charger [all Apple brands] - cut the recharging time drastically over the original 12W charger}.
You conveniently deleted the relevant portion of mamallama's post regarding the current (Amperage) if you connected the batteries in series.
No, I did not. You've replied to the wrong person.
Yes.
I already use the camera on/off switch, like normal.
This is true at 7.2volts. However, you'll notice I mentioned that they are 1.2 volt batteries. I did this because most people I talk to don't realize that NiMH batteries doffer in voltage from alkaline batteries. Volts x amps = watts, hence why I described at 1.2
Yes, most people realize that NiMH D cell batteries are only 1.2V and your camera needs 7.2 V. Your setup only provides 10,000 MAh at 7.2V, the voltage that operate your camera.
This setup does not provide any short-circuit protection which UL or CE certified Li-Ion batteries provide. The certified Li-Ion batteries also provide overheating protection but that is not a concern because there are no batteries inside the camera.
Using the right size wires and good soldering techniques should solve this as the internal resistance of good NiMH batteries are sufficiently low.
