Cummins Onan QG 2800i Gasoline RV Generator - 2.8HGLAA-8311, 2.8 kW Prime, Single-Phase, 120 Volt, Air-Cooled, EVAP
The Cummins Onan 2.8HGLAA-8311 QG is a compact yet powerful 2,800-watt gasoline-powered generator designed to provide dependable power for smaller RVs, camper vans, and travel trailers. Engineered with advanced Quiet Gasoline™ technology, this generator is built for efficiency, reliability, and quiet performance-making it an ideal solution for off-grid living or extended road trips.
This model operates with a remarkably low noise output of 66 dB(A) at 10 feet under half load, exceeding the strict noise standards set by the National Park Service at 60 dB(A) at 50 feet. The fully enclosed design, coupled with an integrated muffler, ensures minimal noise disruption, allowing you to enjoy the tranquility of your surroundings without sacrificing power.
With its pure sine wave electrical output and digital voltage regulation, the 2.8HGLAA-8311 ensures consistent and clean energy for running sensitive electronics like laptops, smartphones, and entertainment systems. This model can easily power a 13,500 BTU high-efficiency air conditioner, with enough capacity left over for smaller appliances and devices.
One of its most notable features is the computer-controlled variable-speed operation, which adjusts engine speed to match power demand, reducing fuel consumption and minimizing wear on the engine. At half load, it consumes just 0.21 gallons of gasoline per hour, making it one of the most fuel-efficient generators in its class.
The generator’s 4-cycle, single-cylinder OHV engine is paired with a pressurized air-cooling system, ensuring consistent performance in high-temperature environments. Weighing only 113 lbs (51.3 kg), its compact and lightweight design makes it an excellent option for RVs with limited space while maintaining robust power output.
Additionally, the generator is CARB-compliant and meets EPA emissions standards, allowing for legal operation across all 50 states. Its safety features include low oil pressure shutdown, high-temperature shutdown, overload protection, and a sealed remote start connector for easy operation from inside your RV.
