Audio buzz feedback when using USB C cable/battery pack

[ New ]

I've been working through this problem for almost a year now. I use an aviation headset audio recording cable for my videos while flying my plane. I have tried numerous cables without improvement. I recently discovered that the buzz feedback was only happening while using the USB C charging cable plugged into a cigarette lighter socket. The feedback goes away entierly when I unplug the charging cable.

 Has anyone used a power supply such as 

DBPOWER 800A 18000mAh Portable Car Jump Starter (up to 7.2L Gas, 5.5L Diesel Engine) Battery Booster with Smart Charging Port,

I have heard on Youtube videos that this eliminates this problem. Any advice would be greatly appreciated.
