The PowerSmart 4400‑Watt Portable Inverter Generator is an excellent choice if you want dependable backup power without the noise or bulk of a traditional generator. It’s lightweight, fuel‑efficient, and packed with features that make it ideal for home emergencies, camping trips, and everyday outdoor use. Lightweight & Easy to Carry One of the first things you notice is how surprisingly light this generator is for its power output. The compact design and built‑in handle make it easy to move around, whether you’re setting it up at home or taking it to a campsite. Quiet Operation For an inverter generator, the noise level is impressively low. It runs smoothly without the loud rumble you get from standard gas generators, making it much more pleasant to use in neighborhoods, campgrounds, or during late‑night power outages. Reliable Power for Essentials With 4400 watts, it provides plenty of power for: - Refrigerators - Lights - Fans - Small appliances - Electronics - Camping gear It’s a great balance between portability and performance, giving you enough output for emergencies without being oversized. CO‑Sensor for Added Safety The built‑in CO‑sensor is a valuable safety feature. It helps detect unsafe carbon monoxide levels and shuts the generator down if needed. This gives extra peace of mind, especially for new users or anyone running it near living spaces. Fuel‑Efficient & EPA Compliant The generator runs efficiently, stretching your fuel longer than expected. Being EPA compliant is another plus, showing that it meets important environmental and safety standards. Simple to Use Starting the generator is straightforward, and the controls are clearly labeled. Even if you’re not mechanically inclined, you’ll have no trouble getting it running and powering your essentials. Overall Impression The PowerSmart 4400‑Watt Inverter Generator is a strong, well‑rounded option for anyone who wants quiet, portable, and reliable backup power.

Lived off it for a month due to impact from a hurricane and its works well as an emergency back up. It is quiet in eco mode compared to others that i have used. Its relatively light so it very portable and best of all it has the display that shows the hours used so you can keep track of maintenance. For the price its great. Wish it had a larger either 2 to 4 galon tank but that would have increased the weight

Upon opening the package, we were met with a strong fuel odor. Touching the item also "contaminated" one's hands. We thought it might be from manufacturer test running it. After airing out several days and weather-permitting, brand new canister of premixed 50:1 ethanol-free 92 octane fuel was poured into the tank. Generator wouldn't start following the startup process in the manual. Bottom of the carburetor became dripping wet. Possibly a stuck carburetor needle. Took off air filter cover. Noticed a crack around where carburetor was attached to the chassis and a flange nut (8 on parts list) was loose. Tapped the carburetor few times. Aired out both the cylinder and spark plug for a several days. Spark plug gapped at 0.6mm, narrower than indicated in the manual. Re-gapped it. Tried to start it again. This time carburetor stayed dry but still wouldn't start. Put in a new saprk plug. No luck. Pull cord was getting worn out by all the pulling. Started the return process.

The media could not be loaded. Weighs about 60 lbs dry. Comes without any fluids, so pick up some 5w-30 and gasoline. It takes 20oz of oil and 1.6 gal of gas. Comes with a funnel and spark plug "wrench." I put in oil and gas today and being an excited idiot, tried starting it without turning on the fuel valve. After a few tries, I checked the manual, and there it is, turn this lever to ON. After that, it started right up. It runs relatively quiet, but in ECO mode it quiets down nicely. At first startup it ran a little rough (vibration), but soon settled into a nice idle. So far, seems like a quality generator.

First off, I have several (4) of these and use them in my handyman trailers. They’re great for a small compact generator. It’s rated at 4400 watts and does just that. I can run my pancake compressor, mitre saw a table saw without an overload condition. My recent one just hit 150 hours and my oldest, a 3 year old unit has 1500 hours on it. The only maintenance I’ve had to do is oil changes and I swapped out the spark plugs to NGK’s and noticed a running difference. The biggest downfall for these is noise under medium to heavy load. They scream pretty loud and the second complaint is fuel use. Under heavy load, you’ll only get 3.5-4 hours on a tank of fuel. These are ideal for construction, general use and certainly good for emergency outages. Do yourself a favor and drain them of fuel if your going to leave them sit for any length of time.

I got this to use as a backup generator for my house. It powers my refridgerator, garage lights/door opener, gas baseboard heater & some important lights with no problem. I am using 10W30 oil in it due to the temperature in the northern part of the US where I live.
