How do objects get the same amount of power from one port as it would from an extension cable that splits said port in 3 or 4, wouldn’t it just cut the power in half or in quarters giving less power to the object?

As others have said, devices *draw* current/power. An outlet can support some large amount of current/power, but it eon’t supply it unless a device is specifically drawing that amount of current/power

That’s why outlets are cool with nothing plugged in. Put your finger in there and you could draw just as much current as a few devices, and it isn’t pleasant.

Think about it this way, power lines don’t know how much you’ll use. But that’s ok, they’ll just send a huge amount and you can use what you need, and the rest gets rerouted
