Between the two hubs, the PULWTOP since it offers PD passthrough. USB-c ports on computers only output 15W and a non powered hub can easily run into issues with devices wanting more than 15W. The PULWTOP is a much more versatile hub but the brand is not familiar to me.

Is there a way to attach a tripod, softbox case, and/or light stand on Pelican or any other hard case?'

Lashing straps? I'd just go with a tripod that could fit inside the case.

Is there a best way to assemble and disassemble digishade quickly?

Just leave the poles in and fold it down.

Whenever I use a super clamp on an aluminum tripod, should I be worry if the frame eventually crushed or squshed or should I consider a carbon fiber tripod?

Its a concern for either material. I never suggest it but if you do just be aware that you don’t need to go HULK on it. Just till it’s not loose.

How do you think about using 2x SSD over SSD+HDD or just 1x SSD alone for backup?

Depends on the work flow. In my opinion, A HDD shouldn’t exist outside of home/office and only then is it for long term archiving. (talking about for stills, not video. video demands much more storage capacity) SSDs are so affordable and have no worry of shock/impact affecting your data. When it comes to data (and other things) ONE IS NONE. If you have a copy on a computer’s internal storage and one external that’s the bare minimum for redundancy. Those two devices shouldn’t live in the same place either. Ideally on a job you have one copy on the computer and two on external SSDs. Then offload to a server or 3rd location when possible.

Are there any pouches for V-mount batteries to prevent scratching and cracking? Cant really find one or should I just use a gaffer tape then?

Nothing dedicated i’ve seen. Theres plenty of things out there that could work if you poke around on Amazon. But also dont see this as a need since they are very robust and made put up with daily use on set. I wouldn’t use them with any form of cover/case as they would trap heat and could impact the lifespan of the expensive batteries.

Are there any shade for 12.9 inch iPad Pro? I think Hoodman used to had one but not anymore...

This one is the most common.

I see some digitechs using Mac Pro for photography uses. It might be overkill but any reasons why they are using Mac Pro? Any specific reasons?

At this time anyone using a Mac Pro for stills is still just riding out their investment in the hardware. The Studio is more than enough for any stills workflow.

Let's say you dont have a car, would you still justify getting an Inovativ cart along with several hard cases?

Hard to say. Depends on your market and the cost of living, storage, car ownership, taxis, ubers/lyfts, messengers.
