Bus-powered or Self Powered??

I jut purchased 10 port hub that came with a power adapter. Do I NEED to use the power adapter or can I just use the power provided via the USB line from my computer?


Hi Michael,

Thanks for posting your question here! When the hub’s power adapter is not connected, the hub is capable of running purely from bus power from the USB port on the upstream host PC.

This takes power from one USB port and shares it with all the devices that are connected. When multiple devices or high powered USB devices are connected, this power will likely not be enough to power up all attached devices. This could cause some devices to work while the rest of the devices become disconnected from the host OS.

We recommend always using the power adapter for best results.
