Charging via USB-C on a motherboard isn't typically fast compared to standard USB ports.
Charging via USB-C on a motherboard isn't typically fast compared to standard USB ports.
It seems my USB-C port on the ROG Strix Z390 gaming motherboard isn't delivering fast charging speeds for my phones. I've used a Galaxy Fold and a Note 20+ Ultra, but neither worked. I checked the wattage specifications online, though I'm not sure what my board supports. I also tried two USB-C cables, but nothing changed.
It seems like you're expressing a feeling of helplessness. Let me know how I can assist you further.
The typical setup is 5 volts with 0.9 amps for USB 2.0, or 5 volts with 0.5 amps for USB 3.0. They likely increased these limits for newer USB standards. Most motherboard makers include a 2-amp fuse or a slightly stronger one for two ports, allowing a device to draw up to 2 amps if necessary. For quick charging, the phone’s charging system must talk to the host device and tell it its capabilities—like supporting 5 volts at 1A, 5 volts at 2A, 9 volts at 2A, or 12 volts at 1.67A—but on a board there’s no way to communicate with the phone or adjust voltage unless it has a dedicated charging port. Consequently, your phone usually sticks to the standard 5v x 0.9A or less.
If the display or the machine uses USB PD (USB Power Delivery) and your device can use it, then the phone might connect to the screen or machine to increase voltage or flow so it could charge more quickly. They also have the option to use QuickCharge on certain ports if desired. However, by default, monitors and computers usually lack this ability to adjust voltage and deliver large currents for fast charging. I notice USB ports on screens exist mainly for ease—like plugging in a keyboard or mouse without needing a long cable behind the PC case, or for quickly connecting an external hard drive. SOME screens can be powered via USB Type-C, providing more than 10-20 watts compared to regular USB, though typical laptop USB-C ports that handle extra power are often more advanced, possibly using Thunderbolt or special power delivery features.
USB-C is merely a type of connector. My USB-C device operates at USB 2.0, which means it doesn’t utilize maximum speed or capacity. The shape itself is what defines it.
