Hello. I purchased this USB-A male to USB-A male cable for an application involving an aircraft experiencing RFI interference with radios using typical USB cables. In short, USB-A to USB-C cables I tried, even with ferrite chokes, caused radio interference when connected to power on the USB-A end and an iPad on the USB-C end. One of the issue is the close proximity of the USB cable to the aircraft antenna, but that can't reasonably be changed.

The linked cable above is essentially double-shielded so I thought I would try it. I purchased a USB-A (female) to USB-C (male) adaptor to go on the iPad end of the cable. I just learned something I didn't know prior - USB-A male to USB-A male cables don't pass power in the typical way? I'm asking that to confirm. I am able to use a multimeter to check for voltage on the pins with the other end plugged into a USB wall charger and can pickup 5V on a pin - is there any way to make this cable work for my application with some kind of adaptor?

I have been searching Reddit for a budget USB C (female) to USB A (male) adapter, and have heard many people advice against getting them at all. Why is this? I know that they could potentially feed back the power into the USB port, but will they still be harmful if I use for data transfer? I would be only ever use it to convert a type C dongle DAC to USB A since my PC does not have any USB C ports. I won't ever use it for charging or anything like that. The one I'm currently using disconnects whenever it moves in the slightest, so I was looking for a replacement.
