Five amps is about 31.25 quintillion (31,250,000,000,000,000,000) free electrons tryna squeeze through your hole in one second
They rub up against each other and that's why things get hot. A significant part of my job is replacing connectors that have burned to a crisp and gotten so angry that they've gone "Right, hell with this" and started to desolder themselves from the board
Electrons are real and they have mass, the more current you draw the more Physically Big the connector has to be, you cannot fix this with software or investment
