Usb extension power cable for Roam 2?

Hi all/anyone

I have a Roam 2 with a Sonos wireless charger and plug.

Unfortunately the lead is too short so I added a 1 metre usb extension lead. All worked well but on one occasion the battery discharged overnight, so I replaced the extension lead with another and all was fine but yesterday the wireless base started flashing red so I took the usb extension out and all it all works, but I cannot put the speaker where it needs to go.

I’ve found out from the Sonos bot that I need a cable capable of delivering 5v/2a (10w) of power. Has anyone had any luck with this?

Thanks for any help.

Take a look at cable in the link on Amazon. If it doesn’t work at least returns are easy.

It sounds like the extension cable is causing too much voltage drop, which can definitely happen with lower-quality or thin-gauge USB extensions. I’d look for a short, high-quality USB-C extension rated for at least 3A power delivery rather than a generic USB extension cable several users have found that the Roam charger can be surprisingly sensitive to cable quality and resistance.

What length do you need? Why not simply buy a long cable?

Or buy a plug extension lead so you can plug the Roam in closer to where you need it?

Hi all,

Thanks for your replies, I agree low grade usb cables are not up to it, but what I’m after is a Male A to Female usb cable ideally one metre and 5v/2A (10w) as it for a Sonos wireless docking station. As for a mains extension lead, it’s already on one, and the situation would take too long to explain as to why I can’t extend the mains cable.

Ta very Much everyone.

One meter is almost a “standard” length. You should find a huge selection to choose from on market sites such as, say, Amazon.

Hi nik9669a,

unfortunately I have two such cables from Amazon in the “use it somewhere else bucket.” What I can’t seem to find is a usb A male to female cable that supports 5v/2a (10w) criteria. Finding a cable supporting this spec on Amazon is difficult as there is very little information. Thus a bucket of duff cables.
