Roam Won't Turn On... I've tried the "hold the button for 12 sec"

it’s the charger that comes from SONOS and the cord I’ve stated this. Regardless it’s not working. The same cord and plug 🔌 aren’t working that worked fine last week! 

I would perhaps go onto contact Sonos Customer Support and see if they can assist. Here is the usual link to get in touch with them:

PD may a preferred standard from your personal point of view Ken but Sonos makes no distinction or recommendation and the one they sell is not PD either.

Quoting scare articles such as the one linked to is not right for me and, dodgy Chinese fake chargers aside, there should be no issue whatsoever in using other non-PD chargers - such as the one Sonos themselves or pretty much any other phone company supply - as long as the minimum specifications are met.  Issues with Roams are highly unlikely to be related to the use of non-PD chargers.

Sonos themselves (rightly) have no issue at all with using chargers above the spec required by the Roam and explicitly state there is no issue with using them.  ‘Any’ charger can have an issue but equally, reputedly branded non-PD ones also have circuitry to protect against such instances.

The vast majority of people use USB chargers they have from old devices or use the one that comes with a device.  PD is (hopefully) the future but totally not an issue without it.

The Sonos Roam charger is LPS (limited power supply) and its power output is 2.1A x 5V (10.5 Watts only) well within the 15W limit shown on the base of the Roam.  It’s designed for use with the Roam, unlike PD chargers that are for use with different devices and different power outputs - That said, I did not realise, earlier in this thread, that @Laney0620 was using the Sonos charger anyway (I missed that point in their earlier post) and was just checking to see if the Roam had been used with a charger that was not PD certified and/or not intended for use with the Roam. It might have explained why it was not charging the Roam.

Hi @Ken_Griffiths , I’m not sure why you keep mentioning PD chargers though, it’s just a (fast) charging standard and every other ‘quality’ charger that can deliver at least 10W will be fine.  It doesn’t matter that the output of the Sonos charger is below what is shown on the base of the Roam - which isn’t a ‘limit’ related to what should be connected at all - it’s simply the limit the Roam will charge at.  Connecting chargers with outputs higher (PD or not) is completely irrelevant (and safe) as it will support 5V - the Roam takes what it needs and no more.

PD as a standard is able to safely deliver pretty high power output - and the Roam doesn’t need a fraction of this.

Hopefully Roam 2 will have much quicker charging speeds and be able to take advantage of these higher outputs - the Roam is a good way from those with a limit of 15W.

I mentioned PD chargers here, because some proprietary chargers may not work with the Roam, they may even cause damage in some instances, whereas a PD charger is much more universal and designed to work with devices, like the Roam.

It is the standard adopted by Google, Apple. Amazon, Microsoft etc. In fact Google will not now certify any Android tablet, or mobile product for use with Google services if its charger is not PD certified. Furthermore  some older Apple 5v x 1A mobile device chargers will not be seen to charge a Roam as their power output is simply too low. 

Adding my name to the list of people who had a Roam die like this.

Which proprietary chargers may not work or cause damage as the latter especially is a potentially serious issue?  They will all supply a minimum of 5V as per USB spec and the Roam should draw what is needed.  Nowhere does Sonos mention or even suggest the use of PD chargers which is specifically what we’re discussing.  If they had any concerns or recommendations, they would detail them.  In fact, as above, they have explicitly stated there is no issue with higher rated chargers so I don’t think unnecessary scaremongering regarding the use of non-PD chargers is at all helpful.

As far as Roam is concerned, there is nothing at all ‘more universal’ in a PD charger as it’s not at all interested in chargers that can deliver 20+V.

What do you mean by PD is the standard adopted by “Google, Apple. Amazon, Microsoft etc.”?  Simply that they (and every other USB device there is?) can use them?  Their devices can use it because PD supports a multitude of charging rates - but so do other chargers and they can be used just fine too if they meet the minimum spec.  Maybe you are confusing cause and effect?

Can you show me something saying Google won’t certify products without their chargers using PD?  Most devices (Google’s included!) don’t even come with a charger so how can they insist the charger needs to be PD certified if it doesn’t exist?  Google released their own Pixel 8 phone a couple of days ago -  where do they mandate this as their newly released phone that also doesn’t come with a charger (like most others) charges just fine with a normal, non-PD charger?  Including their own previous gen non-PD charger that was for the Pixel 7 - as everyone would expect!  It will just be slower.

Why is it relevant that an older Apple charger of 5V x 1A will not bee seen to charge a Roam - it is below the recommended supply written by Sonos.  From Sonos: “While Roam is capable of charging with a 5V/1.5A (7.5W) USB power adapter, you may experience slower charging times.“

I also have a PD charger capable of charging two devices really quickly (it’s GaN too) that charges my wife’s phone at a speed we hadn’t even seen on the display before (I think it was ‘Super Fast Charging’) when using Samsung’s own ‘fast charger’.

PD really is the future (and the now too for some) even though it’s been around some time in reality, but it’s just not really relevant for devices with such low charging requirements of 5V and 2A such as the Roam.

I think you’re missing the point of my posts @sjw the Sonos Roam mentioned by @Laney0620 was not actually charging in their case - Not personally realising initially that they were using a Sonos charger, I simply asked them to post the charger power-output - Had it been a PD charger, as I highlighted, it should have been charging okay. So I think you’re reading too much into things here. There’s no scaremongering at all, other than I guess if the wrong voltage is used with a proprietary charger, then it might cause damage and some lesser-quality imported chargers may spike too, I guess.

Note too that I also asked if they were using the original cable that came with the Roam, that’s important here also, as that will not support todays PD chargers as the one end is USB Type A - so that’s all I was trying to discover.

A USB-C PD charger should work ‘for sure’ was the point being made. Some PD certified chargers also come with both USB-C and USB-A ports - I would have gone onto recommended trying the PD certified port instead as in my experience the USB-A port can (on some chargers) be underpowered, particularly if multiple devices are connected to the charger.

I have not gone into replying to every aspect of your post, as I think it’s mostly irrelevant to the purpose of the thread and is not relevant to me wanting to know if a PD certified charger was being used on this occasion when attempting charge the speaker. If you see that as scaremongering then I’m afraid that’s very much your own issue and certainly not my intention.

Saying not using a PD charger or a charger with a higher capacity than Roam requirements can cause damage is scaremongering and not true (except that it could be said ‘any’ charger could be faulty and cause ‘damage’) - yet you said both.  Contrary to what you say above, I never suggested asking if a PD charger was being used was scaremongering, that’s a silly twist of words to suit.

I’m not ‘reading’ into anything - the other aspects were responding to points you wrongly made imho - especially the irrelevant Google, Apple assertions etc. to justify PD when Sonos has no need of it.
