DEWALT 5,700W Gas Generator Review

Summary

The DEWALT DXGNR5700 is a gasoline-powered generator built around a 5700 running watt output, which places it squarely in the mid-range power category. At that wattage, this unit can simultaneously run a refrigerator, a sump pump, several lights, and a window air conditioning unit during an outage. It can also handle most corded power tools on a job site, from circular saws to air compressors, without breaking a sweat. The 7125 starting watts give it enough surge capacity to kick over motor-driven appliances that draw heavy inrush current, like a well pump or a larger portable air conditioner.

DEWALT has long been a name associated with professional-grade construction tools, and the DXGNR5700 carries that same expectation of rugged reliability. This is not a lightweight camping inverter or a small recreational unit. It is a full-frame, open-frame generator meant to deliver serious household or job site backup power when the grid goes down or when an extension cord simply will not reach.

Power & Runtime

Running on gasoline, the DXGNR5700 draws from a 6.7 gallon fuel tank. At 50% load, which translates to roughly 2850 watts of continuous draw, the generator runs for about 10.5 hours on a single tank. That means a user running a refrigerator, a few lights, and a phone charger overnight could reasonably expect to get through the night without refueling. For heavier loads closer to the full 5700 watts, fuel consumption will increase significantly, and users should plan for more frequent trips to the gas station.

Because the unit includes automatic voltage regulation, the power output stays clean and stable even as the load fluctuates. AVR keeps voltage within a tight range, which is critical for anyone plugging in laptops, phone chargers, or flat-screen TVs. Without AVR, voltage spikes and sags can shorten the life of sensitive electronics or damage them outright. The DXGNR5700 handles that concern at the hardware level.

No noise level data is available for this model, so prospective buyers should plan to test placement distance from living or working areas before committing to a permanent setup location.

Outlets

The DXGNR5700 includes four NEMA 5-20R outlets, each rated at 120V and 20A. These are standard three-prong household receptacles, the same type found on the walls of any American home. They accept the plugs from everyday devices like fans, lamps, phone chargers, power drills, and kitchen appliances without any adapters. Having four of them means users can spread loads across multiple circuits rather than daisy-chaining power strips, which reduces the risk of overloading a single outlet.

The unit also has one L14-30R twist-lock outlet rated at 120/240V and 30A. This is the outlet that matters most for whole-house backup. With the right transfer switch and inlet box installed by a licensed electrician, this single connection can feed power directly into a home's breaker panel. The twist-lock design prevents accidental disconnection under vibration or tension, which is important when running a heavy load through a single cord. For job site users, this outlet also powers 240V equipment like welders or large air compressors, though users will need to stay within the 5700 watt continuous limit.

Portability

At 172 pounds, the DXGNR5700 is a heavy machine. That is roughly the weight of an average adult male, and it means one person should not attempt to lift this generator into a truck bed alone. Moving it requires either a second set of hands or a set of wheels and a handle, and users should factor that reality into their purchasing decision. This is not a grab-and-go unit.

The physical footprint measures 27.2 inches long by 27 inches wide by 25.7 inches tall, which is nearly a perfect cube. That shape makes it relatively compact for its power class, and it should fit in the corner of a garage, the bed of a full-size pickup, or a storage shed without consuming excessive floor space. Still, the combination of that weight and those dimensions means planning ahead for storage and transport is not optional. It is necessary.

Features

Starting the DXGNR5700 requires a recoil pull. There is no electric or remote start option here, so users need to be physically present and able to give a firm pull on the cord. For most healthy adults this is straightforward, but it does add a layer of effort compared to push-button models, especially in cold weather when engines can be stubborn.

The generator includes GFCI-protected outlets, which automatically cut power if a ground fault is detected. This is a genuine safety feature that protects against electrical shock, particularly in wet or damp conditions common on outdoor job sites or during storm-related outages. A built-in spark arrestor makes the unit safe to operate in areas with fire restrictions, including many national forests and campgrounds that require this feature by regulation. CARB and EPA compliance means the DXGNR5700 is legal to sell and operate in all 50 states, including California, which enforces the strictest emissions standards in the country.

The fuel gauge is a small but meaningful inclusion. It lets users check remaining fuel at a glance without opening the tank cap, which reduces guesswork and helps prevent unexpected shutdowns mid-use. All outlets are covered, shielding the receptacles from rain, dust, and debris when not in use. This matters for any unit that will spend time outdoors.

DEWALT backs the DXGNR5700 with a 3-year warranty, giving buyers a defined window of manufacturer support for defects and failures. That is a solid commitment for a gasoline generator in this price range and signals confidence in the build quality.
