can usb-c flash drives be externally powered with the end that isn't being used. I know they don’t have to be powered by the unused end, but I want to know if they can be.
USB-C flash drives are typically designed to draw power from the host device they are connected to, such as a computer, smartphone, or tablet. The USB-C standard allows for power delivery and data transfer through the same port, which is why these flash drives do not usually require external power.
However, the concept of externally powering a USB-C flash drive through the unused end is not standard practice and is generally not supported by the design of most USB-C flash drives. These devices are not built with the necessary circuitry to accept power from an external source on the unused end. The power and data lines are configured to work with the host device, and introducing power from an external source could potentially damage the flash drive or the host device.
If you have a specific use case that requires additional power, you might want to consider using a powered USB hub. A powered USB hub can provide additional power to connected devices, ensuring that the flash drive and other peripherals receive adequate power without relying on an unconventional setup.
In summary, while USB-C flash drives are designed to be powered by the host device they are connected to
