    Summary

    The Ryobi RYi2500 is a gasoline generator rated for 1850 running watts with 2500 starting watts. That combination targets everyday portable power needs while still leaving headroom for the extra surge required when certain devices first switch on.

    Because it runs on gasoline, the RYi2500 fits shoppers who want a familiar fuel source while keeping the focus on compact, on-demand electricity rather than fixed installation power.

    Power & Runtime

    With 1850 running watts and 2500 starting watts, the RYi2500 is built to handle steady loads while also accommodating brief startup spikes. In practical use, that starting wattage can make the difference between a device starting cleanly and tripping the generator when a motor or compressor kicks in.

    Noise is rated at 69 dBA, giving you a clear expectation for how present the generator will sound during operation. The unit is also rated at 3 percent THD, and paired with its inverter design, that low distortion level supports clean power delivery for sensitive electronics. For runtime, Ryobi lists 7.5 hours at 50 percent load, which helps frame how long it can keep devices running before refueling. The runtime at 25 percent load is given as 0.

    Portability

    At 50 lbs, the RYi2500 stays within a weight range that many users can move without needing special handling equipment, which matters when you are loading it into a vehicle or repositioning it around a campsite or work area. Its dimensions of 18.5 x 11.5 x 18 inches reinforce that portable intent, keeping the footprint compact enough to store and transport more easily.

    Features

    Starting is handled through a recoil system, keeping operation straightforward and mechanical. The generator includes indicators, which can make it easier to monitor status at a glance while it is running.

    For usability and safety oriented details, the RYi2500 is parallel capable, letting you scale output by linking it with another compatible unit. It also includes a spark arrestor and covered outlets, both of which add practical protection for outdoor operation and for the receptacles themselves. Automatic voltage regulation is built in as AVR, supporting steadier output under changing loads. Compliance is listed as EPA and ANSI/PGMA G300-2023, and the generator is backed by a 3-year warranty.

    Recommended Audiences

    • Users who want to scale output via parallel operation
    • Owners of sensitive electronics seeking clean inverter power
    • Shoppers who prefer gasoline-powered generators
    • Campers and outdoor enthusiasts needing portable power
    • Users who need a lightweight, portable power solution

    Est. running: 200W

    These are estimates using typical wattage assumptions. Real appliances vary. Startup surges can be 2–6× the running wattage for motor-driven loads. 240V loads require a 120/240V generator and proper connection. Use a transfer switch or interlock kit; never backfeed a panel.
