30-port USB 300W Space Saving Desktop Charger

How do I know if my USB port is data or power?

1. If you connect a device that requires charging, such as a smartphone or tablet, and it starts charging, it suggests that the port is a power-only port. If the device does not charge or prompts for data transfer, it indicates a data transfer port.
2. Plug in a USB device, such as a flash drive or smartphone, into the port you want to test. If the device is recognized by your computer or prompts for data transfer, it indicates that the port is a data transfer port.
3. Check if the USB port has any symbols or labels next to it.Common symbols include a lightning bolt for power-only ports or a USB icon for data transfer ports. Not all devices may have clear labels, so you may need to proceed with further steps.
4. If you want to be absolutely sure, you can use a USB tester. These devices can measure the voltage and current flowing through the USB port, allowing you to determine if it is a power-only port or if it supports data transfer.
