👉 USB "fumes" refer to the overheating and potential damage that can occur when USB devices are not properly managed or when they are subjected to continuous high power usage. This happens because USB ports draw significant current, especially when transferring large amounts of data or powering high-capacity devices like external hard drives or SSDs. Over time, repeated overheating can degrade the internal components of USB cables and connectors, leading to reduced performance, intermittent connectivity issues, or even complete device failure. Proper use, such as avoiding rapid back-and-forth transfers and ensuring devices are compatible with the USB port's power delivery capabilities, can help mitigate these risks.
