Technical Details

Product Description

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.

XP4400 panel
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.

Your Generator Needs

To determine whether a generator is appropriate for your needs, you need to first add up the wattage of tools, appliances, and motors you want to run at the same time. 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.

Hurricane Sandy knocked out our power for 9 days. We ran this generator 15-24 hours a day during that span. We ran (2) 20 cubic ft chest freezers, (1) 14 cubic ft fridge, and (1) 27 cubic ft fridge/freezer on it all at once (we connected two first, after 4 mins, we added the other 2, as starting 4 fridge/freezers at once would create quite a surge). Throw in a few lights, some phone chargers, and our gas range (power is only needed for the igniters). This generator has worked flawlessly. I did the initial oil change after about 40 hours (I think the manual wants it much sooner) and the oil was cleaner than I expected. This generator is quieter than my neighbors' as when I go outside, I hear theirs louder than ours (the specs on this unit show that it is quiet for a generator - this is useful if many of your neighbors are running generators and you are worried about theft. As long as neighbors are running their generators, and you have yours hidden, no one will know you have one.). The generator seems to run through its 4 gallons in about 12 hours with the load that I was using (probably less than 1/2 of it's rated output). Although it seems to do better after the engine has broken in now. We started to get quite cold without heat, so I even hooked up my gas furnace to it which requires power for the blower mostly (disconnected 2 of the freezers when running it). I don't know what I would have done without it. After Hurricane Sandy, it was very difficult to find an open gas station. This unit seems to be efficient on fuel, yet it will run enough things in your home to be useful. I feel that we could have added even more load, but I didn't want to be stranded since there were no generators available in stores for hundreds of miles.Read more ›

The DuroMax XP4400-CA is a strong little work horse. I've had one for 2 years and use it to power my travel trailer. I have run it day and nite and it never over heats. Usually for my needs one tank of gas lasts all day and into the nite. It supplies all of my electrical needs with little effort. I don't have A/C or I would probably need the larger model. Outside my trailer it sounds loud to me but when I am inside I hardly notice the noise. You have to make sure that it is level or it won't run properly. My electrical needs are: Microwave, Refrigerator, Water Heater, lights, Television, and Toaster Oven. I can't run the Microwave and Toaster Oven at the same time because of the wattage output. You never have to worry about using too much oil because it hardly uses any oil at all. It is easy to start, usually just one pull does it. The wheels and handles make it easy to move around. This is a strong generator and almost maintenance free. I say almost maintenance free because it is a good idea to clean the air filter once in a while, but other than that and checking the oil; as long as there is gas in the tank this generator keeps on working problem free. If you are thinking about getting a generator and you want a reliable one with a low price this is the one to get.

It's a really nice little generator for the money. We ordered prior to Sandy and got one for less than $400. So far I haven't had to use it in an emergency but the power output is good in all my testing. I run it for about an hour a month just to keep it in working order.

Pros: It has a good wheel kit included. The fit and finish was good for what it is. Starts easily. Lots of power options on the control panel.

Cons: A little on the loud side. When the power is off all over the neighborhood it's going to stick out like a skunk at a campfire. However big your generator is, you always wish it was bigger. Really this is as big of a generator as I'd suggest for emergency power because of fuel consumption. It's not too bad on gas but over a few days it'll go through a bit. You have no choice but to store some for emergencies which is a pain.

A better choice is probably a multi-fuel setup so you can tap natural gas but that was a wee bit more money than we wanted to spend at the time. Since we use lots of gasoline for yard maintenance it works for us but I worry about getting caught short. I'd also look at one of those mini 900w generators to conserve on gasoline while keeping the furnace running.

I was worried this generator wouldn't make it to me intact, since I live in Hawaii, but it did! The packing protection was superb, no damage at all! After a few minutes to remove the shipping protection hardware and install the wheel kit, this baby was ready to run! I filled it with gasoline, (by the way, it is made to run on gasoline with up to 10% ethanol) and gave it 5 pulls on the starter cord with the choke on and it fired right up! After that it only took 1 to 2 pulls with the choke on with the "easy-pull" starter cord! It ran really smooth, it was a bit loud, but not any louder than my 5 HP Honda Pressure washer motor. In fact I think it was a little more quieter than my Honda pressure washer motor. I haven't had to really use it yet, but I'm counting on it the next time we get another bad storm and a power outage! This gives me a bit of peace of mind, since my house is all electric and I have a refrigerator and a chest freezer! I really don't want to spend bucks on tons of ice to keep my food from rotting everytime we get a bad wind storm.
