We are power-hungry, we have 370W solar and a 6kW diesel genny - but we also have a watermaker and like plenty of water, and run laptops and TVs as much as we please. A genny will make your lives much more comfortable but when it comes to portables, storage space, petrol storage and noise are key issues.

The Honda ones are very quiet and you don't want a noisy cheap genny rattling away in an anchorage - you and your neighbours will get very upset. Is 1kW big enough for you? Most vacuum cleaners take more than 1kW and most 1kW gennys are not rated for 1kW continuous - probably around 700W continuous. How big is your battery charger - 80A takes about 1kW at full output. A water heater will draw 750W upwards. A microwave will take well over 1kW. A Foreman grill or equivalent takes over 1kW as does, maybe, your toaster.

The 2kW Honda would be a better buy, I think, then you will be able to run every appliance on board albeit not at the same time. An ammeter will help greatly when running the genny to decide how to load it, especially until you get a handle on the draw of each item.
