WiFi Max Router Power Input Voltage

[cruz123]

I have installed a new WiFi Max Router using the supplied power supply and cable.  I need a longer cable and note that there is a second input power supply port - a conventional centre pin arrangement.  However there is no indication of the required voltage.  Is it 12V?

No one can help?

here's a pic of the back of the new sr213, as you see no voltage given over the power in port.

The booklet says 12v. The old sky hub power supply actually fits this port.

You can buy USB-C extension cables.
