Roku streambar power

Can the new stream bar be powered by plugging into the USB on the back of the television or does it require its own power source?

Re: Roku streambar power

Most tv USB ports don't have sufficient power to reliably operate a Roku that is only a streaming device.  The power needs of a combined streaming device and sound amplifier would be considerably higher.  Plug it into house power.

Re: Roku streambar power

And I would like to know if the streambar powers down -  is there an on/off switch or a button on the remote?  If it was USB powered then  no problem, but if USB isnt an option , how does it power down when not in use?

Re: Roku streambar power

ROKU----how much power is required from a USB port ?   My Samsung tv powers the Roku express just fine and I like that it powers down when I turn the tv off

Re: Roku streambar power

I probably should have said "some" tv USB ports don't put out adequate power for a Roku, rather than "most". Also the USB ports on some tvs turn off with the tv, on others they stay active.

I'm just a user, and don't have an Express to check, but my Rokus came with adapters rated as putting out 1 amp. The original USB spec only called for 0.5 amp and that's what a lot of tvs still deliver. This may be adequate for some operations of the Roku but may not be enough when there are higher power requirements for some operations, like coping with weakened wifi signals, higher bitrate transmissions, etc.

Re: Roku streambar power

Have you seen the power brick that comes with this thing?  It has a separate power connection on the back; it doesn't use the USB port for power.
