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?

Answer 1

A circuit is designed to handle a certain amount of current. Devices draw current depending on their need/electrical characteristics. Once the sum of current draws exceeds the current the circuit was designed for, the breaker breaks, or if there is no breaker a weaker component will melt, or burn.
