There's already something about this topic in the campsite netiquette part of the CA guide, I hope everybody agrees to this:
- Have a chat with your campsite neighbors before setting up a noisy generator alongside their pitch – offering cold beer or some electricity for their cooling devices will usually ensure acceptance.
- Setting up your tent close to a generator is entirely your fault - you have no reason to complain about noise if the genny was there first!
I've just bought a genny myself last week and the noise-level was the most important feature for me - not only because of the campsite neighbors, but also I myself don't like spending a whole week besides a noisy genny. But there is of course the price. Comparing 1-kw-gennies, i found that cheapies run for less than 100 Euros, they're simple but produce usually around 90 db or even more. For a similar sized low-noise genny (less than 60 db) you have to pay at least 200-250 Euros, and if it should be an inverter type genny - sensible enough for electronics like DVD-Players. TV's, cameras - it's around 300-350 EUROS.
In general: we'll switch it off around 1 am, turn it on again around 8-9 am, we like a quite night ourselves For the cooling devices that's no problem, they'll keep the temperature until next morning and if we still need light after 1 am there are candles, gas-powered lights and torches and our battery-powered portable stereo will also still work.
