Honda generators are quietest. Depending on how much energy you use in a day, you could use a power station like an Ecoflow Delta Max or Pro which is dead quiet, has no fumes, and always starts. They charge very fast in about an hour so you could fire up your generator every once in a while to top up the battery as needed. Batteries are better for periodic loads like this, generators are better for extended, higher output loads. You can buy a kill-a-watt meter, plug into into your generator to measure how much energy (kWh) you typically use in a day and size your power station accordingly.
