At 4KVA and 220VAC out, then max current is 18.2A. For me, this is still pluggable to a regular outlet with a breaker switch of at least 20A, and with your main switch off (very important!). I'd say that this can support a 1HP A/C, plus refrigerator and various lightings.....

Coleman powermate is a good brand (with briggs and stratton engine). And, do not worry about the 100VAC outs. Most probably, the genset was intended for the US market or a country which has its power requirements at 110VAC. One 220VAC out should be good enough...
