A five-port USB desktop charger that supports multiple output voltages: 5V, 9V, and 12V on all five ports. The specific output voltage depends on the connected device; different devices require different voltages. Typically, standard USB outputs 5V, but when compliant with the QC protocol, it can deliver higher voltages—commonly 9V or 12V for smartphones. Some devices also support high-current 5V charging, while others only accommodate low-current charging.
