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.

  • You want the flexibility of running on gasoline or propane without extra kits.
  • You plan to power an RV with the built-in 50 Amp outlet.
  • You value a budget-friendly option compared to tri-fuel models.

Choose a Different Model If

Pulsar 12,000W Dual Fuel Portable Generator: Final Verdict

For most buyers looking for a reliable home backup generator, the Pulsar PG12000B is a strong choice. Its dual fuel capability, high output, and RV outlet make it a versatile tool for emergencies. The electric start and digital meter add convenience, while the CARB approval ensures it can be used nationwide.

Its main weaknesses are the weight and noise, which are common for this class. The Champion 201438 offers tri-fuel and CO Shield, but at a higher price. If you do not need natural gas, the Pulsar gives you excellent value.

Ultimately, the Pulsar PG12000B is our pick for most home backup needs, especially if you want a simple dual fuel setup. The Champion 201438 is the better choice if safety sensors and fuel variety are top priorities.

Frequently 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.

Detailed Review

The Pulsar PG12000B is a heavy-duty dual fuel portable generator designed for homeowners, off-grid users, and RV enthusiasts needing substantial backup power. With 12,000 peak watts on gasoline (9,500 running) and 10,800 peak on propane (8,550 running), its 457cc OHV engine handles large appliances, well pumps, furnaces, and even AC units during outages, as confirmed by multiple users running entire homes.

Standout features include Switch & Go technology for on-the-fly fuel switching without shutdown, electric push start with recoil backup, and a full suite of outlets: four 120V, 120/240V twist-lock, 50A RV, and 12V DC. Reviewers highlight its propane reliability, with one user powering nearly a whole house from a 100lb tank, and another using it off-grid seamlessly alongside solar setups. The 3-in-1 digital meter aids maintenance tracking.

Build quality shines with a steel frame, 10-inch never-flat wheels, and drop-down handles for maneuverability despite the 209-pound weight. Its CARB approval ensures legal use everywhere, and the included mobility kit plus propane hose add value. While loud like competitors, proper placement minimizes noise indoors.

Drawbacks include the need to charge the battery periodically for gasoline starts and minor assembly issues like fuel line nicks in isolated cases, easily fixed. Overall, the PG12000B delivers exceptional value for reliable, versatile power.

Verdict: Highly recommended for anyone prioritizing dual fuel flexibility and high output in a portable package. It excels in real-world emergencies, earning top marks from satisfied owners.
