That's pretty much the same generator I have (mine's red & black). I live in a first floor apartment, but could put it out on the balcony if I had to, to run the microwave.
We have a Super Ser gas heater, and (too) many full 25KG cylinders. I keep falling over the damn things in the spare bedroom (we were given them for nowt a while back)
Solar phone charger is a good shout, I hadn't thought of that.
