Summary
The DEWALT DXGNR4000 is a 4000-watt gasoline generator built around a 223cc OHV 4-stroke engine. This wattage class sits at the threshold between household backup and light job site work. At 4000 running watts, it can power a refrigerator, sump pump, and several lights simultaneously during an outage, or run circular saws and air compressors on a construction site, but not both at full capacity. The 5000-watt peak handles motor startup surges, which matters when appliances draw 20 to 30 percent more current at the moment they turn on. The DXGNR4000 targets users who need portability without sacrificing power. A 3.4-gallon fuel tank delivers 10 hours of runtime at half load, meaning a full tank gets you through a night of backup power or a full workday on site. The recoil start requires physical effort to fire up, but it eliminates the complexity and cost of electric ignition. DEWALT backs this unit with a three-year warranty, signaling confidence in the engine and electrical components.
The Powermate PM3800 is a durable and compact portable generator, ideal for home use and DIY projects. It features a Generac 212cc OHV engine, delivering 3800 starting watts and 3000 running watts. The generator offers a 21-hour runtime at 25% load, facilitated by a 5-gallon fuel tank. Its POWERDIAL™ simplifies the startup process with an integrated off/run/choke knob.
