    Engineered for Performance

    Designed by Firman, the 208cc cast-iron sleeve engine packs a punch despite its compact size. Clocking in at 3,650 watts of running power, the P03608 portable generator is capable of powering household appliances and high-amperage power tools, perfect for small homeowners and professionals alike.

    An automatic voltage regulator, the built-in Power Stream Alternator controls sudden electrical surges that could harm the device. This guarantees the portable generator's output consistency and safety.

    Extensive Runtime

    Built with efficient fuel usage, the Firman P03608 lasts for up to 14 hours at half load so you can worry about the tasks at hand and keep your thoughts off the oil gauge.

    The low oil shutdown function automatically shuts down the engine when oil levels are low, preventing the usage of contaminated oil from causing harm to the device. It also has a low oil indicator that acts as a heads-up.

    Usage Safety

    The P03608 remains safe to use even indoors thanks to both EPA and CARB certifications.

    Globally recognized, the Environmental Protection Agency and the California Air Resources Board’s regulations aim to reduce toxic emissions to prevent health hazards, and this gas portable generator complies with them to ensure your safety.

    Fully Loaded Power Panel

    To help you accomplish your tasks, the Firman P03608 houses 3 different outlets so you can plug whatever it is that you need to be powered.

    Whether you choose to start the unit using its recoil mechanism, electric start, or remote, you can immediately begin producing power and get to work.

    The fully featured power panel also features circuit breakers that prevent any electrical risks or fire hazards in case of an overload.
