Is a 1800 watt generator big enough for a 1800 Sq. Ft. home?

Asked by: Anonymous
No. It may run a few lights, TV and charge cell phones but it will not be large enough to run a refrigerator, electric stove or a furnace unless you are ONLY running one of these. I would look at something around 5000 to 7500 watts and only run what you absolutely need to run. If you want to run a central air system I would have at least 10,000 watts and professionally installed. Also, have an electrician wire a connection to your furnace blower so you can plug the blower into the generator. I have another 7500 watt generator I use in the event of a winter power outage. In summer I can live without power for a few hours but in Winter the furnace is a must have. 1800 watts is a small generator

can I use the 120/240 twist lock outlet to power a 240 V 5HP air compressor

Asked by: TomB
No there is not a 220/240 VAC outlet, only a duplex 110 VAC outlet. I've had mine three years and it runs fine if you don't overload it.

can this be used to power impact wrenches, small roto hammers on construction sites

Asked by: Anonymous
It depends on the power rating of the tool. If you can run the tool plugged into a standard 120 volt/15-amp house outlet, you shouldn't have any problem.

Customer Reviews

1,800-Watt Gasoline Powered Portable Generator is rated 4.7 out of 5 by 25.
Rated 4 out of 5 by from A Good Little Generator I purchased this generator for ice fishing and to power my fish house. I have a larger fish house that is equipped with propane heat, stove and bunks. I needed the smaller generator to run a coffee pot, a few LED lights, TV and CPAP machine. It works great. I do run everything through a surge protector in the event of a power surge from the generator but so far all is well. It works fine for this. The oil fill isn't easy to use. A special funnel comes with the unit but doesn't work too well. If I tilted the unit back it was OK but keep checking the level so you don't overfill. It is a bit heavy but I can put it in and out of the back of the truck fairly easy but a smaller person may have a problem lifting it up. Starts easy, even in below zero weather. The location of the pull start could be better. The frame is in the way but not a big deal. The only regret was that a week later I saw a 2200 watt on sale, for less than I paid for this one. Oh well.

Rated 5 out of 5 by from This product has the exact requirements I was looking for. The generator is exactly what I needed in size and performance. It handles the chores so I don't have to lug the larger one around. It delivers the 15A and is light enough to pickup and move around effortlessly.

Rated 4 out of 5 by from Easy to use I haven't had to use it at full capacity yet but it started up right away. I've never owned a generator nor was I familiar with how to use one but this brand was recommended by neighbors. The directions were easy. Minimal noise. Easy for me to handle by myself.

Rated 5 out of 5 by from Outstanding value and quality Bought this for camping. Use it to run lights, music and coffee maker. Needed something easy to start and dependable. Two 20 amp outlets just fine. 1-2 pull start up, ran nearly 12 hours 1st day on the job. Easy to transport.

Rated 5 out of 5 by from Nice little generator I have only used the generator a few times but so far I am very impressed. Right out of the box, it started with 2 pulls. Fairly quiet engine. Not like a Honda but then it doesn't cost as much as a Honda either. I used it for powering a "Skil Saw" and it works great. Craftmanship appears very good. Highly recommended.

Rated 5 out of 5 by from Real Quality Unit I needed a small generator to power a 1/3 HP compressor occasionally, in a building with no power. I knew I needed at least 1260 watts and the GP1800 seemed ideal. After reading customer reviews and making comparisons to similar sized/powered portable units, I opted for the Generac based on past experience with brand quality and durability, price and availability. I ordered online on a Monday night and it was picked up Friday morning. Getting the unit set up presented two minor issues: first, the dedicated funnel provided does not work well, I had to prop up the generator at 45 degrees to fill, which worked great. The second issue was start up instructions. The manual indicated there were multiple choke settings when in reality there were only two-on and off. Like I said-minor issues. Started up easy, very quiet, no problems. I would definitely recommend the Generac GP1800 for any task requiring less than 1800 watts (if you want to know how much power you need for a specific tool, multiply Amps x Volts to get Wattage). FWIW, my second choice was the Generac GP3250.

Rated 4 out of 5 by from Still think I made a good choice, BUT,... The first, "just out of the box" test run was at once a success and a failure. The success: It started (took a few pulls but that's no surprise with the carb and fuel lines empty) and ran smoothly (it's quieter than I expected - a bonus). The "fail" part: BOTH vibration mounts on the unit's left side ("left" relative to the end where the recoil starter, air cleaner, and choke lever are located) BROKE (rubber and metal separated) while I was attempting to start it (and no, I didn't use excessive force pulling the starter rope). I'll be contacting Customer Service about getting replacements.

Rated 5 out of 5 by from Good value Bought for emergency use only, to power a sump pump and maybe a gas fired heating system in winter. Used only once so far, to help a friend during power outage. It started up easily. They were able to run their heating system (hot air), which was nice because temp was down to freezing at night. Since then I tested it one other time during mid-winter, to make sure it would work in cold weather, and it started up no problem. This unit has one duplex outlet with 15 amp breaker. Only enough power for essentials, but that's all I wanted. It is relative small, and one able bodied person can move it if required.
