Safeguard your family as well as provide portable power for work and play with the CARB compliant DuroMax XP4400-CA gas-powered generator, which features a 7.0-horsepower air-cooled OHV engine that cranks out 3,500 constant running watts of power (and a peak of 4,400 watts; learn more about wattage needs below). This rugged workhorse is ideal for the jobsite where powering saws, drills, and other equipment is critical, but you can also depend on it for emergencies at home--insuring your essential appliances are running smoothly, reliably, and without interruption. Never-flat knobby tires and flip-up handle (view larger). This generator is EPA approved with a rating of 69 dBA for quiet operation thanks to its super-quiet muffler, and it"s also safe to use in U.S. National Parks thanks to the super quiet exhaust with spark arrestor. Fully loaded power panel (view larger). The XP4400 includes two 120-volt, 20-amp standard household outlets to supply power to all of your appliances as well as a powerful 120/240-volt, 30-amp twist lock outlet for high-powered tools. A 12-volt DC output with leads functions as a charger for batteries and other rechargeable devices. Overloads are never a problem with its dual 15-amp circuit breaker. A volt meter allows you to monitor your generator"s output range at all times. The exclusive DuroMax RV Switch (voltage selector) allows you to get maximum power from each of the 120-volt receptacles as well as choose between operating the generator at both 120 and 240 volts simultaneously, or at 120 only with full power. The XP4400 features a heavy duty steel frame roll cage with four-point fully isolated motor mounts for smooth and quiet operation. This generator is also easily portable thanks to the wheel kit with large, all-terrain knobby tires that will never deflate and a flip-up, stow-away handle. You"ll get up to 8 hours of run time (at 50 percent) from a 4-gallon tank of fuel. Other features include an advanced automatic voltage regulator (AVR) system and a low oil protection system which automatically shuts the generator off to protect it from any damage should it run out of oil. It"s backed by a one-year limited warranty.

Then select a generator with the running wattage rating to match or exceed the total load. Keep in mind that tools and appliances with electric motors require additional surge wattage at startup that can be double or triple the normal running wattage requirement. Look at the surge watts required and make sure you choose a generator with enough additional wattage to start them. (And remember that you"re typically not starting more than half of the items at the same time.) Here"s a sampling of power ratings for common household appliances.
