You need to make sure your converter will not overload the 800 watt genny. If you can control the converter (PD's can have a pendant to control) you should have no problem.
A converter over 45 or 50 Amps might overload the genny.
I had one of the 2cycle little generators, and you are aware that they are a POS, but it did work for awhile. You are aware that anyone around you is going to give you dirty looks.
Test it out before you leave, making sure the voltage is OK; the first one I got put out about 140 Volts, took back and second was OK.
