Power For New Roku

[Dave_H_M]

Just got a Roku stick that plugs into a HDMI port. Power cord that comes with it kinda resembles a cube with a USB plug for the power cord to the stick.

So now you can buy a shorter cord that plugs into as usb on the TV and straight into the back of the Roku.

So the thought hit me, why can't I just take the usb of the power cord provided and stick it into a usb on the back of the TV, instead of using up another outlet.

Will my idea work or will I have something go kapoof?

thanx

My fire stick at home works on one TV when you use the TV USB but it does not work on the other.

specs say 2 watts , at 5v thats 400MA

that should work from the TV usb, if the TV does not give you any errors

It's worth a try. Check the TV manual for the USB power output.

Also, you can get outlets with a USB built in. Pretty handy!

As MrWizard said the TV USB port may be under powered but in most cases I have seen your idea works just fine. Another problem I've run into using your idea is that the TV thinks something it should use is plugged into the USB port and either pops an error or locks up trying to 'see'/use what is plugged in...

look at the rating on the power cube
odds are its more power aka amps than the USB port on the TV, which designed as an input port an maxes out at about 500 MA

you can try it.. but the roku probably will not work correctly,
