How does a portable power generator work?
Portable generators provide electricity by running a gas-powered engine. That turns an on-board alternator to generate electrical power. Power outlets on the unit allow you to plug extension cords, electric-powered tools and appliances into it.
How much does it cost to buy a whole house generator?
A smaller 3,250-watt portable model might set you back about $300 to $400, while a 10,000-watt model might go for about $1,200. If you want the whole shebang — the whole house generator — a 20,000-watt model will cost you about $5,000 at Home Depot. Still other generators go for as much as $10,000.
How many things can you run on a 5500 watt generator?
For example, if you are running 4,000 watts of appliances off of the 5,500 watt generator and you need 2,100 watts of start-up power for your freezer, temporarily unplug the coffee maker and the television. Both of those appliances together use approximately 2,000 watts of power.
