Summary
The Pulsar G12KBN generator stands out as a versatile power solution, capable of delivering reliable electricity for various applications. With a dual fuel capability, it can operate on both gasoline and propane, making it an excellent choice for users who seek flexibility in fuel options. This generator boasts a starting wattage of 12,000 watts and a running wattage of 9,500 watts, making it suitable for powering essential appliances during outages, outdoor events, or even job sites.
Designed for both home and recreational use, the G12KBN is equipped to handle a range of power needs. Whether you are looking to keep your refrigerator running during a blackout, power tools on a construction site, or provide electricity for a camping trip, this generator can meet those demands. Its robust features and solid construction ensure that it can be relied upon when you need it most.
Power & Runtime
The Pulsar G12KBN operates on dual fuel, allowing users to choose between gasoline and propane based on availability and preference. This flexibility enhances its usability, especially in emergencies where one fuel source may be more accessible than the other. The generator offers a starting wattage of 12,000 watts and a running wattage of 9,500 watts, providing ample power for multiple devices simultaneously.
With a noise level of 74 decibels, the G12KBN operates at a moderate sound level, which is comparable to the noise produced by a vacuum cleaner. This makes it suitable for residential areas where noise restrictions may apply, though users should still consider the sound when using it in close proximity to neighbors. The starting mechanisms include both recoil and electric start options, giving users the convenience of starting the generator with ease.
Runtime is a critical factor for any generator, and the G12KBN does not disappoint. When running at 50% load, it can operate for up to 12 hours on a full 8-gallon fuel tank. This impressive runtime allows users to maintain power for extended periods without frequent refueling, providing peace of mind during prolonged outages or outdoor activities.
Outlets
The Pulsar G12KBN features a variety of outlets designed to accommodate different devices. Although specific outlet types are not listed, the generator is equipped to handle multiple connections, ensuring users can plug in essential appliances and tools. However, it is important to note that the G12KBN is not RV-ready, which may limit its appeal for those looking to power recreational vehicles directly.
Additionally, the generator does not support a transfer switch capability, which is a consideration for homeowners who wish to integrate it into their home electrical system. Users will need to rely on extension cords and other methods to connect their devices, which may not be as convenient as having direct connections available.
Portability
In terms of portability, the Pulsar G12KBN weighs 209 pounds, which is substantial for a generator of its power class. While the weight may make it challenging for a single person to move, the generator is designed with a sturdy frame that enhances its durability. Its dimensions measure 28.5 inches in length, 21.8 inches in width, and 22.2 inches in height, providing a compact footprint that can fit into various spaces.
The generator is equipped with handles that assist in lifting and transporting the unit. However, it does not feature wheels, which could have further facilitated mobility. Users should consider this aspect if they plan to move the generator frequently, as additional effort may be required to lift and transport it.
Features
The control panel of the Pulsar G12KBN is designed for user-friendliness, providing clear access to all necessary controls and displays. Though specific display features are not detailed, users can expect standard indicators for fuel level, power output, and operational status. Safety features are essential in any generator, and while specific safety features are not listed, users should always adhere to safety guidelines when operating any generator.
Included accessories are not specified in the product details, but users should consider purchasing additional items such as heavy-duty extension cords or surge protectors to enhance the generator's functionality. The one-year warranty provides users with some peace of mind regarding the generator's reliability and performance.

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.
