“but this one can be hooked in parallel with another for 2kW is you had to have that. “
Do not do that - if they get out of phase, you will fry everything.
My company actually tried to invent a device to allow that behavior - two multi-million-dollar labs went down in flames.
YMMV.

They want a good chunk of change for that cable, as well as another 1$k for the 2nd generator. Cannot imagine needing 2kw, so no way for me. Merely interesting as the cost for higher capacity generators climbs fairly quick, and portability declines in pace.
