Question USBC-PD powered 3.5” enclosure?

[NedSmelly]

I would like to know if an external enclosure for a single 3.5” HDD that is powered by USBC-PD exists.

I require large external storage for video/photo editing on location. I am currently using multiple 5TB bus-powered HDDs which are all filled to capacity.

I have started to use a 3.5” desktop HDD enclosure with an 8TB HDD as a trial replacement, but having to carry the extra wall brick PSU is annoying. A USBC-PD powered enclosure with an 18-24TB HDD would be ideal (e.g. as a separate power cable to the data USB). Thank you!

Hard drives require both a 12volt and a 5volt power supply. So a single usbc port is not going to work; its not about the wattage that the usbc port provides; its about the voltage. So if your laptop does not have 1 port available at each voltage (and most only support 5volts) you will still need the brick to supply the 12volt line. Or you could switch to drives that only require 1 5volt line.

Thanks for that. Yeah I wasn’t sure about the engineering aspect of it. It was more a case of being able to use a smaller GaN charger to power both laptop and HD enclosure, or a PD-compliant power bank. Just one less thing to lug around. Sounds like it’s not an option.
