Power the bridge independently?

Can the bridge, which normally plugs into the back of your cam, be powered straight from a USB power supply?
To get coverage in my house I currently have the cam/bridge combo in a central room where the cam function is not actually needed so if I could just have the powered bridge in there it would free up the cam to be placed in a location where it is needed.
Anyone tried this?

The bridge needs to communicate with the cam to get the sensor info to the app.
