Addendum: Unfortunately, the adapter is now broken - the sailboat is the vehicle voltage (12V) not always constant and so he has suddenly begun to hum then a bang and the adapter was burning hot and over. After the open could be seen that a capacitor has exploded. (Not easy to replace, easy backup would be better here) Despite Solder a new capacitor, it stops working completely. The green light comes on briefly, then faded again. So it is likely to have carried more than just the loss of condenser. Since the adapter is still great but in itself, it remains at 5 stars. - A proper fuse (replaceable) would be desirable!
