7KVA could power your whole house. A 2KVA Honda EU20i can comfortable run a full size fridge and freezer, and also power a few lights and possibly your TV at the same time. We had to for about a week, last time we had a big storm. Dunno about the specs on the cheapie Gennies, how accurate they are etc, but you'd be pretty comfortable with a 3KVA for most stuff. If you plan to use a small inverter welder, go for the 3KVA. My Honda won't quite handle 2.5mm electrodes at anything over about 80A. I can do small 1.5cm runs, but the penetration isn't great.
As for camping, that's a tricky one. Do you really want to be running a genny while enjoying the serenity? and the cheapies are really noisy. My Honda E20i is one of the quietest, and I find it very annoying after a short while, not to mention anyone else near you. Better off getting a decent solar set up (>300W panels and a couple of 100AH deep cycle batteries) and you can run a decent sized 12V fridge, water pump, and even a small TV as well as LED lighting, and be off grid for weeks, depending on sunlight of course.
