I have the 1kva black ridge which is the same, only use it to charge the camper battery with a 16amp projecta charger works fine- each to their own but I couldn't justify the big price of a Honda etc. simply to charge the battery.
Just for the record my neighbour has the 2kva battery start, the battery didn't last long but he's wired it to start off the car battery via his Anderson plug, he is also happy with his, he bought the bigger model as he sometimes uses it with a heater in his camper.
