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.

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.
