Bongo Fury

My last Bongo only had a 12v outlet in the back but my Freda MY99 has a 12 & 100v the green light comes on when the ignition is turned one notch. Does anybody know if this actually outputs 100v and if so with an adaptor could i run my laptop off it which needs 100-240v?

There is a small 100v (japanese mains voltage) inverter behind it, but personally I would not want to try using it. It only runs off the rather feeble wiring that goes to the 12v socket at the rear.
