About this tag
The usb charging tag on WindowsForum.com collects discussions about how USB power delivery works in practice, especially the difference between a cable's wattage rating and its data speed. A recurring theme is that a USB-C cable rated for 240W charging may still transfer files at USB 2.0 speeds, so charging capability alone tells you nothing about throughput. Threads also touch on identifying cables, USB-IF labeling, and how Windows users can sort out which cables and ports actually support fast charging versus fast data. It is a practical tag for anyone troubleshooting power, cables, or device charging on Windows hardware.
