Atlas Copco P3000W Portable Generator | 2,800W Gas, 11-Hr Runtime

Atlas Copco P3000W Portable Generator: Big Power in a Compact, No-Nonsense Package

When a barn loses power at 3 a.m., when a remote jobsite needs lights and a tile saw, or when a backup well pump has to kick on during a thunderstorm, the Atlas Copco P3000W portable generator delivers the dependable, clean 60 Hz electricity you need. Built around the Atlas Copco AC200FA 196 cc OHV gasoline engine, the P3000W produces 2.5 kVA of continuous power and surges to 2.8 kVA — enough to fire up power tools, run agricultural equipment, and keep freezers, lighting circuits, and small motor loads going for up to 11 hours on a single 4-gallon tank.

It's the entry point in Atlas Copco's renowned P-range of portable generators, engineered with the same robust attention to detail you'd expect from a global leader in industrial air and power. Whether you're a contractor outfitting a service truck, a rancher protecting livestock during outages, or a homeowner who wants reliable emergency backup, the P3000W is the gas portable generator that earns its keep.

Why the Atlas Copco P3000W Stands Out

• Automatic Voltage Regulation (AVR) holds output voltage steady so you can power sensitive electronics, electric motors, and modern jobsite gear without spikes or sag.
• 11-hour runtime at rated load on a 4 US-gallon fuel tank — set it and forget it overnight or run a full shift without refueling.
• Heavy-duty open-frame chassis with a full roll cage and anti-vibration mounts protects the engine and alternator on bumpy jobsites and farm runs.
• NEMA L14-30R twist-lock for 120/240V plus a 120V duplex outlet — feed a manual transfer switch and run handheld tools at the same time.
• Low-oil shutdown, circuit breaker, and hour meter protect your investment and make service intervals easy to track.
• One-person portable at 115 lb (52 kg) and 23¼″ × 17″ × 19″ — lifts into a pickup with one person and a tailgate.

Full Specifications

Built for Real Work

Construction & contracting

Power a circular saw, a worklight, and a charger off the duplex outlet while a tile saw or small air compressor runs on the 30-amp L14-30R. The AVR keeps voltage clean for inverter-controlled tools and battery chargers.

Livestock farms & agriculture

Keep heat lamps, ventilation fans, vacuum pumps, and refrigerated bulk tanks running through a storm. Eleven hours of autonomy at nominal load is enough for most overnight outages on a single fill.

Home backup power

Wire the L14-30R outlet into a manual transfer switch and selectively power your well pump, refrigerator, sump pump, and lighting circuits during a grid outage.

Outdoor events & small worksites

Light enough to load alone, quiet enough at 73 dB(A) to position behind the action without drowning out conversation.

Sizing and setup notes

Rated output is 2,500 W continuous and 2,800 W peak at unity power factor, enough to start small motors with locked-rotor current up to roughly 7.5 amps. A typical 3/4 HP residential well pump draws about 2,000 to 2,500 starting watts and 750 to 1,000 running watts, well inside that. A 13,500 BTU RV air conditioner needs roughly 2,800 to 3,000 starting watts, which sits at the top of the surge spec and can be tight depending on soft-start. The P3000W is recoil start, so no battery is required. Oil is sold separately; fill with SAE 10W-30 before first start.
