Does the Chromecast Audio have to be powered by the provided USB power supply?

Hey so i've just set up my Chromecast Audio and i wondered if it matters that i am powering it by  the usb port on my music system rather than using the supplied the USB Power supply plug, it seems to all work fine so i can't see it being a problem?

Just wondered if there any benefits of using the supplied USB power supply plug? Will it make any difference to the sound quality?

Thanks in advance.

You don't HAVE to use the included power block.

Google doesn't suggest using ports on audio or video equipment for a couple of reasons.

First, those ports are often data-ports and are un-powered or under-powered since they are intended to read data off of memory sticks and not actually POWER some kind of hardware device

Second, they often turn off when you turn off the TV or audio system.  That means that the Chromecast loses power and can't stay ready and can't fetch critical updates quietly at night when you aren't using the Chromecast.  When they do power up, there can be a lag while the Chromecast gets the update and applies it.  I just had that happen with a Chromecast Audio I had temporarily disconnected.  I plugged it back in after a week or so, started casting, and then it shut down on me a few minutes later because it had to do an update.

If your audio system seems to be providing enough power (and it sounds like it is) and you're willing to live with the issues of the prime-time update... you can keep with your current situation.

But, if the Chromecast seems to stutter or loose WiFi connection, I would switch to getting your power from the power-block right away.

Hello Byteguy.

Thanks for your response, i understand what you are saying and your information is indeed very useful.  :)

For your information i am using a Marantz M-CR603 system to power up my Chromecast Audio and the device only powers on when the system itself is on, when the system is off (I don't leave it on standby) the indicator light on the Chromecast Audio switches off, so i would presume the device is switching off there....

I may see if i can leave my Marantz system on standby mode and then hopefully the Chromecast Audio will remain powered. However i don't really mind about the fact of not receiving prime-time updates and i can happily wait at the time if there is any updates, so i may just leave it as it is.

I'm more concerned about the effect on sound quality (if there is any) than the prime-time updates.

I will see how it goes and if i seem to run into any issues, i will change to using the USB power supply plug instead.

Thanks.

You should be fine with letting the Chromecast Audio power-down.  It doesn't hurt anything.

Sound quality shouldn't be impacted at all.  I have one unit that I keep moving around my house from system to system (I REALLY should have bought a few more when they were on Black Friday sale last week) so it spends a lot of time unplugged and it's always been fine.

Great, thanks 'Byteguy'.

I'll keep it powered via the USB port for now then. I've always got the option to plug it in via the mains if needed/necessary.
