Starting Watts is the amount of energy it takes to initiate the start appliance or tool. Running Watts is the amount of energy it takes to keep that appliance or tool running once initialized.
Estimate both the amount of starting watts and the running watts needed to run the essential appliances before deciding how large a generator to purchase. The final decision as to what size of generator to buy can partially be based on just how well one manages the power usage. Managing usage is accomplished by having only those appliances running that are needed when needed. Otherwise turn them off. This allows a smaller generator to power more appliances more efficiently.
Items with an * notation take as much energy to run as to start.
