I've received a PD power bank that looks like it could work (Anker Nano Power Bank 22.5W), and the camera should arrive in the next couple of days.

To test the fit, I'll need to remove the optical cables from the A1 housing, but I'm not sure how theses work.

Do I just need to unscrew the two nuts, and then the cables can be removed without any risk to the housing?
Thanks

Dont unscrew the nuts. They are part of the housing construction and holds the fiber connectors outside the housing and have o-rings in the construction.

You need to just pull the led's (unless they are glued or something) out. Mine (trt) are just pushed in, not sure about other brands.

Here is mine without led's:

You should also probably remove the trigger as well - is it an UWT trigger or some other type? What are the cables attached to?

bghazzal's pictures on previous page show the cable is just hanging, with a connector in the end so i'm sure its like my trt one, trigger in the camera hot shoe and connect it to the cables when sliding in.

expect you're right, I couldn't see the connector which is why I mentioned it.

Thank you both - yes, that was easier than I thought 😃 I just pulled on the cables and the fiber optic cables slid out

The power bank fits - now I need to test it with the camera to see it it works.
If it does it will just be a question of routing a flat USB cable.

The powerbank I got is this one:
https://www.anker.com/products/a1653-usb-c-portable-charger-5000mah?variant=42733234258070

Capacity: 5,000mAh

USB-C Output: 5V⎓3A / 9V⎓2.22A / 10V⎓2.25A

Total Output: 18W Max

It has a dual output, male on the length (which I plan on using) and female on the side.

I ordered a Ribbon Flat USB-C Data Cable 3A 10Gbps female to male and male to male, we'll see.

As a follow-up, I can confirm the Anker Nano above powers the A7SIII. Handshake works and it charges the battery when idle. I haven't tried filming in 4K 120fps yet but don't there's no reason it shouldn't work to extend in-cameri battery life.
Now i need to find a good ribbon cable for a housing setup.

As an update, my camera tray finally arrived today and I got the camera in the housing for the first time.

I can confirm it works - the Anker powebank fits in the housing and powers/charges the camera - the only thing I will need to look out for is cable routing, to make sure they don't get in the way of any gear operation.
I used an 20cm aliexpress 10Gbps ribbon cable for the powerbank. It fits with HDMI cable plugged in (I used a Nauticam HDMI cable rather than my Weefine screen's, as the Nauticam cable is shorter and faces the right way for my camera's HDMI port)





Here is the A7SIII in its NA-A1 housing, with the Anker battery pack connected and a Weefine WED-5 Pro screen connected, currently vaccum testing the whole thing (I have the 28-60 in a 100mm port, hence the nasty vignetting - I'll set up the 100mm later today)






Depending on camera battery / use, the powerbank charges the battery or, when it gets low, extends battery life. Camera battery was at 65% and it's now up to 78%

cheers
