Pulsar G12KBN Portable Generator Review

Pulsar G12KBN is a heavy-duty portable generator. It runs on both gasoline and propane and features a powerful engine to produce higher output power. Unlike many conventional generators, it produces a clean sine wave. It has a big fuel tank, a variety of power receptacles, an hour meter, and basic safety features.

Pulsar heavy duty generator


Generator Type: Pulsar G12KBN is an open frame conventional generator. It is a powerful unit that can be used during power outages at home to run a variety of appliances. Also, you can use it outdoors to power tools at a construction site.

Dual Fuel Technology: It is a dual fuel generator. You can either choose gasoline or propane to run this unit. Propane is easy to store and readily available during emergency situations or natural disasters. So, if you are not getting gasoline from any source, you can switch to propane to keep your life running during outages.

Transportation: This generator from Pulsar is quite heavy. It weighs 209 pounds but thanks to its 10-inch durable wheels and fold-down handles that make transportation quite easier and safer.

If we talk about its size, then it is 21 inches wide, 28.5 inches in length, and 22 inches in height.

Emissions: It meets the emission standards set by CARB (California Air Resources Board). So, you are allowed to ship and use this generator in all 50 American states.

Warranty: Pulsar G12KBN has a 1-year limited warranty.

Starting Method: A convenient push-button electric start system along with a recoil backup make life stress-free

Engine: Constructed with a powerful and reliable 457cc, 4-stroke, single-cylinder OHV engine. It is well-protected under a durable powder-coated frame. To prevent overheating of the engine during operation, there is an air-cooled system. It uses air, unlike the liquid-cooled system, to keep the engine’s temperature down.

Power Production Capacity: Its powerful engine is capable of producing 12,000 watts of starting power and 9500 watts of running power on gasoline. But, with propane, this output power goes slightly down to 10,800 starting watts and 8550 running watts.

This output power allows you to run mid-size to large homes. Also, at job sites, you can run multiple heavy-duty power tools.

Clean Sine Wave: Pulsar G12KBN also allows you to connect sensitive electronics as it produces a clean sine wave. With a less than 5% THD (Total Harmonic Distortion) rating, this generator is quite safe for delicate electronic items like smartphones, laptops, gaming systems, and others.

Less THD rating means there is less voltage or current distortion due to harmonics present in the signal.

Tank Size: It has a big fuel tank size of 8 gallons, made up of steel. A fuel gauge is also there for the users to check the remaining fuel level easily.

Run Hours: An 8-gallon gasoline tank allows the Pulsar G12KBN to run up to 12 hours at half load. If propane is used, it can run up to 5 hours at half load on a 20-pound tank.

The gasoline consumption of this unit is 0.67 gallons per hour, and its propane consumption is around 0.94 gallons per hour.

Noise Level: It produces 76 dBA of noise from 23 feet. This decibel rating makes it a noisy unit.

Power Receptacles: Pulsar G12KBN features both AC and DC outlets.

A 12 Volt 8 Ampere DC outlet is for charging batteries only. Other than this, there are four 120 Volt 20 Ampere (5-20R) household outlets, one 120/240 Volt 30 Ampere (L14-30R) outlet, and one 120/240 Volt 50 Ampere (14-50R) outlet.

With all these outlets, you can power a variety of appliances and tools. The L14-30R receptacle makes this unit transfer switch ready. Connect the generator to the manual transfer switch of your house to get power to your whole house during outages.

Hour Meter: You can track maintenance intervals and keep an eye on the status of the generator with the help of this hour meter. It is a very useful feature that displays total runtime, voltage, frequency, and run/maintenance time.

Oil Alert Lamp: There is also an oil alert lamp on the control panel. This alert indicates that the remaining oil level is insufficient to run the engine.

Safety Features: It comes with automatic low-oil shutdown, overload protection, and an automatic voltage regulation system.

Overload protection shuts down the engine when you apply additional load to the generator. It prevents overheating. The low-oil shutdown also automatically turns off the engine if the oil level is too low. The automatic voltage regulation system maintains a constant voltage level.

 My Opinion:

Pros: Pulsar G12KBN is a powerful generator available at an affordable price. It is dual fuel and produces clean power. It has a big-sized fuel tank that gives decent runtime. It is easy to operate and features both AC and DC outlets and an hour meter to track maintenance intervals.

Cons: Its decibel rating is higher. Also, it only offers a 1-year warranty.


Does Pulsar G12KBN come with Switch and Go Technology?

No, this model doesn’t feature Switch and Go Technology. If you need to switch from gasoline to propane, you need to turn off the gasoline supply, turn off the master switch, and then connect the propane tank with the generator to start it. Same thing you need to do when switching from propane to gasoline. Disconnect the propane supply, turn off the master switch, and then turn on the gasoline supply to restart the generator.

What things can you power simultaneously at home with this generator?

You can simultaneously run the following things in your house during a power outage.

  • Dishwasher
  • 10,000 BTU air conditioner
  • The microwave of 1000 watts
  • Sump pump of ½ HP
  • Electric frypan
  • Refrigerator
  • DVD player

These are just examples of items that you can power simultaneously. Always check the starting and running watts of the items you are going to power to prevent overloading.

Does Pulsar G12KBN come with a battery?

Yes, Pulsar G12KBN includes a battery.
