Is there a charging cable which splits into two? One of the split cable will have DC 12v 3a with a male coaxial 5.5mm x 9.5mm The other split cable will have DC 5v 3a with a USB Micro.

Does this exist? If so, where can I buy one? If it doesn't exist, how can I make one?

probably the easiest way to make that would be to take a desktop 12V 5A power supply and splice a 5A buck module into the output cord

Sellers of cheap buck modules tend to over-estimate their capability by a bit - that's why I reccomend a "5A" modules to suppyk your "3A" need. a search for "XL4015 5A" should get you some examples of the type of module I mean. cost is about $1 on aliexpress or banggood

If you can live with a lower power level a hard drive testing power supply can typically do 12V2A and 5V2A simultaneously
