Ho un sacco di alimentatori USB-C (alcuni con diversi wattaggi).
Il Mac dovrebbe caricarsi più velocemente (o esplodere) se collego due alimentatori allo stesso computer (diversi slot USB-C)
No .
Il tuo MacBook si caricherà da quello che fornisce una maggiore potenza. Citando il documento di supporto Apple, Connetti con Thunderbolt 3 sul tuo nuovo MacBook Pro :
Notes on charging your MacBook Pro:
Your MacBook Pro draws power from only one power supply, even if more than one is attached—so using multiple power supplies won't speed up charging.
If you connect multiple power supplies to your MacBook Pro, the one that provides the most power will be used, regardless of the order in which you connected them.
You shouldn't connect any power supply that exceeds 100W, as it might damage your MacBook Pro. Also, using a power supply that doesn't provide sufficient power can result in slow or delayed charging. It's best to use the power supply that came with your Mac.
