Yep, the case is nice. You can remove just the top set of screws and the top half lifts off for easy access.

Sorry, I meant the carrying case not the actual PS case. The PS case looks like an extruded Al case with PCB end covers.

Best,

Both. Both are nice.  :)

I just tried this power supply with my Xiaomi power bank. I was thinking "Portable power supply!".

It powers on OK, but ... it failed to negotiate more than 5V input from the power bank which means only 4.1V output into a load.  :(

I know my power bank can do more than that but not with the FNIRSI. Maybe it would work if you find the right one.  :)

The FNIRSI uses USB-C PD, this means you must use a USB-C cable and cannot have any old style USB connection involved as they do not support more than 5V (Except with non USB approved protocols  like QC).

I know, I've been powering it using a phone charger. It negotiates 20V from the charger and works just fine.

My phone charges at much more than 5V if I plug my phone into that power bank but the FNIRSI doesn't like it.  :-//
