I would like to use a GTi14 or SER9 in both the EU and the US, and am unsure about the power issues. Can you confirm or correct if both products can be powered in the EU from a “US” power supply / power cord plugged into a US -> EU plug adapter, e.g. the products themselves can work with either 120V or 240V power?
Also, is it correct that the GTi14 accepts AC voltage into an internal power supply, while the SER9 accepts DC voltage from an external power supply into either its DC or USB4 port? It is difficult to tell from the website.
