Cummins Onan P2500i 2200W Portable Inverter Generator, Gas Powered, Quiet Generator with USB Ports, RV Ready, EPA Approved

Cummins’ Onan P2500i portable generator is gasoline powered and ideal for use in an RV, campsite, or home. It’s an inverter generator, it’s compact and lightweight, and its full one-gallon fuel tank can run 550W continuously for 10 hours. At only 48lbs without fuel, it’s easy to take on mobile adventures, and it is strong enough to start high demand loads such as a portable table saw.

This portable generator runs continuously at 2.2kW, with a peak power output of 2.5kW. On one tank of fuel, the 2.2kW is enough to power an air conditioner for roughly 2.5 hours. Appliances with smaller power demands, like a refrigerator, can run much longer on a single tank of gas. If a configuration requires additional power, it’s possible to parallel two P2500i’s for a maximum continuous output of 5kW.

The paralleling process is simple and requires a single cable connecting the two generators. Both generators can run an air conditioner and other appliances for a few hours, but total run time depends on the total power output and the available fuel.

The Onan carburetor manages the ratio of fuel and air injected into the generator engine. The required ratio changes at various elevations, and this generator operates up to 2,000ft. Higher elevations require the additional high altitude carburetor kit to keep the P2500i operating up to 7,000ft.

This compact generator includes two outlets and two USB ports above a system display screen. The digital display shows detailed information about the output voltage, output current, and remaining run time. LEDs beside the panel also indicate the fuel level and power output percentage.

As an inverter generator, it has low THD (Total Harmonic Distortion). This means the generated power has few fluctuations in frequency or voltage, creating premium power that is safe for sensitive electronic devices like clocks, fans, and TVs.

Accessing the P2500i’s interior for maintenance is simple and requires no tools. A single rotating lock holds the side panel in place, and removing the panel allows users to manually check the oil level, fill the oil, or perform other maintenance tasks.

Onan’s ultra-quiet 2.5kW generator is well insulated to eliminate excess noise. It runs around 73dB (decibels) under normal operation, but the ECO option can drop this to 52dB. The ECO option conserves fuel by limiting the motor RPMs to only that needed by the required loads, and it allows for greater surge capacity.

Choose the Onan P2500i for a reliable, lightweight, and EPA approved generator for mobile adventures.
