At a heavy 96 pounds, this generator does not include a wheel kit making transport difficult. Also, with no inverter, you risk running your more sensitive electronics. Finally, you’ll need to monitor oil usage more closely as this model does not employ a low oil shutoff.
With its ability to run for up to 9 hours on a 100% load on nearly a full 4-gallon fuel tank, the Goplus gasoline portable generator earns its place on our list. This 4,000 watt generator employs a 208cc engine with a forced air cooling system to prevent overheating. The control panel includes status lights to quickly access operations.
We placed the Goplus generator last on our list for lacking quality control, its moderately loud operation, and for lacking helpful and important features such as an inverter for clean power output, an eco-mode for fuel efficiency and an engine saving low oil shutoff. Plus, at 91 pounds, this generator does not offer a wheel kit. However, it does have a handle incorporated into its design.
Hopefully our reviews along with our pros and cons list have helped you to decide which 4,000-watt portable generator you need. Before you make an investment in a particular product, take a quick moment to consider certain important factors that make or break a high-quality generator.
When you’re deciding on a generator, it’s important to have the ability to run it for an extended amount of time since you’ll most likely need to use it for a long period. Several of the generators we reviewed ran for more than eight hours on a single tank of fuel. Also, you’ll save on costs if you purchase a generator with an eco-mode function. On eco-mode, the generator meets the exact demands of your output needs without overproducing and wasting fuel.
Another vital component to look for is an inverter. An inverter makes sure only clean power output reaches your phones, tablets, laptops and other sensitive appliances. Without an inverter, you risk damaging these electronics.
Also, you may want to make sure your next generator has a low oil indicator or better yet, a low oil shutoff. Generators need frequent oil changes. Remembering to check the oil may not always be on the top of your mind. This simple helpful feature can save your generator from severe engine damage.
All gasoline or propane powered generators produce noise. Save your hearing and perhaps nasty looks from your neighbors or nearby campers by checking into the noise level before you purchase your next generator. Most of the products we reviewed emitted a moderate level and mostly acceptable level of noise. Any generator that operates loudly should be avoided.
Finally, we must discuss portability. 4,000-watt generators are heavy-duty machines with the emphasis on heavy. Most of the products we reviewed on our top ten list average around a hundred pounds. Even the lightest models we featured weigh a considerable amount. Wheels make an enormous difference in your ability to transport your generator from storage to where you intend to operate it and back again. Be aware that wheels are not a given on most 4,000-watt portable generators. In many cases, you’ll need to make a separate purchase for a wheel kit.
The Champion 100302 RV Inverter Generator is our top pick for the best overall 4,000-watt portable generator. With an innovative open frame inverter design, this generator performs well and offers an eco-mode, extended running time and clean power output. It includes helpful and convenient features such as a quick touch panel, a low oil shut-off sensor and a reliable recoil start. Plus, the Champion is parallel ready and affordable. Its only drawbacks are that you will need to purchase the parallel kit and the wheel kit separately. Also, this generator operates at a moderate noise level.
The DuroStar DS4,000S Gas Powered Portable Generator is our choice for the best value. The DuroStar has a powerful 7-horsepower gas engine and comes with important features such as a fuel gauge, a low-oil shutoff and a variety of outlet options on its power panel. However, what you save in price, you lack in an inverter for clean power output, an eco-mode for better fuel efficiency and wheels for transport. Additionally, the separately sold wheel kit may be difficult to install and this generator produces a moderate noise level during operation.
The Pulsar PG4,000iSR Portable Gas-Powered Generator is our premium choice. This generator performs well with an extended operation, an inverter for clean power output and an electric push start. Plus, the Pulsar comes with parallel capability, several outlet choices and a remote control for conveniently operating this generator from a distance. Additionally, this generator is easy to maneuver and store. And, it’s C.A.R.B approved and compliant in all 50 states. The Pulsar is more expensive than other products on our list. This generator does not include an eco-mode, needs a break-in period and makes a whiny noise when operating at full load.
Hopefully, our useful reviews, our factual pros and cons list and our helpful buyer’s guide have helped you make informed choice for your next purchase. With the right 4,000-watt portable generator to meet your energy requirements and the ability to transport it to where you need it, you can power up your devices, work your appliances and run your heating and cooling system with confidence.
