In-Depth Review of the Pulsar PG12000B
Running and Starting Power
The Pulsar PG12000B delivers 12,000 peak watts and 9,500 running watts on gasoline, with slightly lower figures on propane (10,800 peak / 8,550 running). This is enough to power a refrigerator, sump pump, lights, and a window AC simultaneously. For context, a typical refrigerator draws around 600-800 running watts, meaning you could run several appliances at once without overloading the unit. This puts it ahead of many competitors in its price range, offering headroom for startup surges.
Fuel Type and Runtime
Dual fuel flexibility is a key selling point. The 457cc OHV engine runs on either gasoline or liquid propane, giving you options during fuel shortages. Users report that switching between fuels is seamless with the Switch & Go technology. Runtime on a full tank of gasoline is estimated at around 12 hours at 50% load, based on typical consumption. This makes it suitable for overnight backup without constant refueling.
Noise Level
At full load, the Pulsar PG12000B is noticeably loud, measuring around 74 dB from 23 feet according to user reports. This is typical for an open-frame generator of this size. It is not ideal for quiet neighborhoods or camping, but for emergency home backup, the noise is a trade-off for the power output.
Portability and Build
Weighing in at over 200 pounds, this generator is not easily moved by one person. However, the drop-down handle and 10-inch never-flat wheels make it manageable on flat surfaces. The steel frame provides durability, but you will want a dolly for rough terrain. It is built to stay put in a garage or backyard.
Outlets and Safety Features
The outlet panel includes four 120V outlets, one 120/240V twist-lock, one 120/240V 50 Amp RV outlet, and a 12V DC output. This covers most home and RV needs. The 3-in-1 digital meter shows voltage, frequency, and run hours. It is CARB approved, meaning it is legal for sale in California. A low oil shutoff and overload protection add safety.

Pulsar PG12000B vs Champion 201438
The Champion 201438 is a direct competitor in the tri-fuel space, offering 12,500 peak watts and running on gasoline, propane, or natural gas. Where the Pulsar wins is in its lower price point and simpler dual fuel setup (no natural gas conversion needed). The Pulsar also includes a 50 Amp RV outlet, which is a plus for RV owners. However, the Champion counter with a higher peak wattage and a CO Shield safety feature that automatically shuts off the generator if carbon monoxide levels are unsafe. The Champion is also quieter at 74 dB vs the Pulsar’s similar but slightly higher noise floor. Choose the Pulsar if you want a straightforward dual fuel generator with an RV outlet at a budget-friendly price; choose the Champion if you need tri-fuel capability and advanced safety features.

View on Amazon.comFrequently Asked Questions: Pulsar 12,000W Dual Fuel Portable Generator
How loud is the Pulsar PG12000B at full load?
At full load, the generator produces around 74 dB from 23 feet, according to user reports. This is typical for an open-frame generator of this size and is comparable to a vacuum cleaner or lawnmower.
How long will it run on a full tank of gasoline?
At 50% load, the Pulsar PG12000B runs approximately 12 hours on a full tank of gasoline. Runtime varies based on the actual load and fuel type used.
Can the Pulsar PG12000B run sensitive electronics?
This is a conventional generator, not an inverter model, so it produces a total harmonic distortion (THD) that can be harmful to sensitive electronics. For devices like laptops or TVs, use a separate surge protector or inverter.
Can I connect two Pulsar generators together?
The Pulsar PG12000B is not parallel capable. You cannot connect two units together to increase power output. If you need more power, consider a single larger generator or a different model.
What is included in the box?
The box includes the generator, a battery for electric start, a funnel, a tool kit, and an owner’s manual. A propane hose is not included, so you will need to purchase one separately if using LPG.
