Hi I'm considering the NUX BT 50 as I need a battery driven amp (we have a lot of load shedding in Saouth Africa) Why does the ext PSU socket say 28V? This is non standard I would have expected 24V - perhaps they mean its the abs max that can be connected? Assuming average volume level (I'm playing against an un miked piano) How long would I expect the internal battery to last - 2hours maybe? Will it run off a 12V car battery but at a lower volume?
