[RFI] RFI-free Vehicle 5v USB Adapter?

[qrv at kd4e.com]

The current noisy adapter provides a 5v 2.1a USB port for cellphone,
and other device, charging plus a digital battery voltage display.

It's also connected to a standard vehicle cigar/accessory plug.

I think this will work:

One review describes RFI & how to tame it.

This would allow me to customize the layout of 5V ports to fit
the location I choose on the dashboard.

It sounds like a good device to work with a Raspberry Pi 4 as well.

Thanks,
