Hi,



as the move came out pretty pricey I have built one by myself:







It runs very well - I am having problems with the oute power down of powerbanks. The speaker uses to less energy when booting up. Kickstarting it with the power cord helps. I will get one from Mi later today with a low power mode to fix the problem.



Here is my how-to: http://tiefenthaler.name/symfonisk/en



With the new Mi Power Bank 2S it perfectly works.
Very impressive!!

Thank you
USB-C with a 35W power pack can directly supply 20V, enough to power the speaker without the need for a DC-DC converter.

I know - but I wanted to do it last week and the delivery time of the USB-C module was too long. I have ordered one and will upgrade the speaker or create another one.

Is the Sonos tolerant enough to accept 20V supply when the typical supply is 24V?

Yes, 20V does work with Sonos. I tried it with this USB C module: https://www.ebay.de/itm/254054864113
Problem: there are not many 20V USB C powerbanks around. So I went back to how it was with the Mi Power Bank.

Hello,
Thank you for this information, and these tips.
Is it possible to recharge the battery by plugging in the cord of the symfonisk speaker, to a wall socket?

It may be annoying to charge the battery very often,  you cannot use your speaker during this time, right?

How long does your battery last, when using your Symfonisk?

 

Thanks again

Hi, in my setup it’s not possible to charge the battery. What I just tried: while playing from battery to plug in a USB charger into the powerbank. But it cuts the USB power output going to the speaker.

So only option with my setup would be: wile listening powered by powerbank plug the speaker with it’s power cord to the wall socket, then disconnect the powerbank from the speaker and plug in a USB Charger into the powerbank. If full, unplug USB charger, plug powerbank to speaker, unplug speaker power cord. Everything works without turning the speaker off and interrupting music playback… But you would have two cables going to the wall socket.

Depending on the volume wit the 10.000mAh Mi Powerbank between 4 and 6 hours

Thank you a lot!

Hi,

i did the work yesterday, i used the booster and the the sonos gets now 24V. I am using the Mi power bank2S and the problem i have i reach only 25% of the Volume.

If i give it a try to increase the Volume the Sonos Play1 makes terrible noises.

Did i do something wrong?

Thanx, pepe

Hi Pepe, 

I’m sorry I am not really a specialist. I just tried and it did work..

Here you can see my experience with different volumes: https://www.reddit.com/r/sonos/comments/d18mkh/sonos_ikea_symfonisk_battery_hack_sonos_move/ezj1eiq/
So I have no problems going to 100% with the Mi Power Bank. I assume you checked if you really have 24V? Did you also check the voltage if the player is running? at 25% or higher?

Sorry, good luck!

Thanks for your contribution. I can now play the Symfonisk in my motorhome using the 12V onboard network. Very pleased!
