I'm currently faced with opportunities to DJ in environments that only have 12V power supply (battery/solar powered). Avoiding conversion to 110/240V would be appreciated. The iPad + Z1 is perfect for this - at least theoretically, as the Z1 still needs 120/240V power supply. Is there any official or know-to-work 12V-DC adaptor available? Of course it's possible to use a 12V->110V converter and than the standard power supply 110V->9V, but the conversion loss seems to be quite dramatic and thus I consider this a stupid way to go.
