Question about JBL Xtreme 2

I bought mine from Subtel for another JBL. Company in DE, delivered as if it were in Switzerland. No price surcharge etc. At least that's how it was for me in 2019.

So you can find the original used.
I would recommend a classic power supply unit with 20V 3Ampere, i.e. 60w.
I have tried it myself and it works very well.
