Here on Long Island our power was out for six days immediately after
Sandy, back for three days, then out again for almost five days after
the nor'easter (just got it back last night). I plugged an 80 watt
inverter from Harbor Freight ($17) into the lighter socket on my Prius C
and was able to run heat (steam boiler, so it has no pumps, circulators
or fans, just the power vent damper and electronic ignition), a couple
of lights, and my internet and phone connections, as well as charging my
laptop and cellphone as needed.

If the inverter can really put out 80W (most are sold by liars) then we know the input draw must be at least 80W. The Prius outlet is rated 120W. There is a conversion loss somewhere in your 80W inverter. So we say that an 80W inverter is about the limit of what one can safely use on a 120W supply. Perhaps you could get by with a 100W unit.
Truth be told 119W isn't going to be safe when 121W is a sure kill. These things are not that predictable. Gut feel from experience says 80W should be safe, 100W might be safe, and 120W rated inverter is certainly not safe at its full capacity because it will be drawing more than 120W.
