I've been thinking how I would make my Sonos One temporarily portable for use on patio for an hour or two. Has anyone tried a portable battery with an AC outlet like this http://a.co/fVsXngp ? Not sure how well it would work or how long it would last but might be an decent option in a pinch.

I'd look for an inverter that offers full sine-wave output, some of the modified sine-wave or stepped voltage output inverters generate excess heat and / or current in your device's power supply. Not long until they fry, I lost several devices to these inverters in my RV travelling days.

Some of the lower quality inverters will work at higher battery levels but cause problems as the battery charge decreases.

You can roughly figure run time by looking at the battery rating in amp hours, take 25% of that (more will lead to short battery life) then reduce that number by 20% more for inverter losses. That gives you your available Amp Hours at 12 volts, divide by 10 to get AHs at 120 volts and you'll be in the ballpark.

The Sonos Play 1 seems to use about 150mA to 400mA at 24V depending on the volume. This means that the Sonos needs about 10W. Unfortunately, typical large lithium ion battery charging pack are only about 20Whr. This means at best 2 hours of unplugged use. You (or Sonos) can make it work, but the battery will need to be inconveniently large especially if you consider that battery capacity decreases significantly with use.

Hopefully a third party will run with this battery carrier idea.

A third party did try, on Kickstarter, a couple years back. It failed to get enough interest.

I regularly use an Omnicharge 20 (http://www.omnicharge.co/products/omni-20/) with a Play 3 and it works great! Get three or four hours playing at about 75% volume.

However, I wish Sonos would just bring out a decent portable!!!

I'm an ex electronics designer. My first Sonos is so old the guarantee has mothballs.

I'm going to open her up and by pass the mains psu and drill for a barrel Jack so I can use one of these usb power banks. How hard can it be.

I use one of these with a One. Never run it all the way down but have gotten 8 hours of it at least.
