Question about PD HUB
Question about PD HUB
Hi,
Imagine a hub with four USB-C outputs and a PD-enabled power supply connected to its input. When a phone is plugged into one of these outputs for fast charging, it works at a higher voltage—up to 20V. If you connect an SSD to another port, could the voltage be affected? Would the SSD's port now match the voltage from the phone’s PD connection? This is confusing; if the power supply is boosting voltage for the phone, wouldn’t that same voltage apply to all four ports? Otherwise, the other ports would need to adjust to handle the increased power, or the device might not work properly.
Taking into account Lutfij's prudent advice, if the hub's construction remains sound and unaltered, you should face no issues. Any suitable Hub will handle the voltage independently for each connected port based on what is attached there. Also note this: numerous Hubs designate certain ports as "Charging Ports." Connecting high-power devices like a phone to these ports serves a distinct purpose from data transfers that rely on USB connections. In the majority of scenarios (though not universal), these ports are exclusively for charging and cannot facilitate any data transmission. Always refer to the specifications and user manual for your Hub to understand this requirement clearly. Each Charging Port manages its own output voltage, adjusting it to match the needs of the connected device, ensuring safe power delivery.
Thank you for your responses.
This aligns with what I expected. It's important to exercise caution when purchasing these new Hubs and gather all necessary details first. Dan
