Pulsar builds portable generators for home backup, job sites, RVs and camping, and its lineup runs from carry-along units that power a lamp and a phone charger up to big frame generators that can take on a refrigerator, a sump pump and a well pump at the same time. If the phrase “Pulsar 12000 watt generator” brought you here, you are probably preparing for power outages and wondering whether that much generator is the right amount, too much or not quite enough.
The quick difference between these six models: two are 12,000-watt dual fuel frame generators, two are larger-output tri fuel machines (one of them an inverter), and two are small gas generators for camping and light loads.

Pulsar G12KBN-SG Heavy Duty Portable Dual Fuel for Whole-Home Backup
Pulsar
Pulsar G12KBN-SG Heavy Duty Portable Dual Fuel Generator – 9500 Rated Watts & 12000 Peak Watts – Gas & LPG – Electric Start – Transfer Switch & RV Ready – CARB Compliant
Price and specifications are read from the Amazon product page and can change.
Pulsar G12KBN-SG Heavy Duty Portable Dual
Best for: Whole-home outage backup with transfer switch
Pros
- 12,000 peak / 9,500 rated watts on gas
- Gas or LPG
- Up to 12 hours at half load
- 50A outlet, transfer switch ready
Cons
- Heavy-duty size to store
- Listing omits weight
The Pulsar G12KBN-SG Heavy Duty Portable Dual Fuel generator is the classic Pulsar 12000W dual fuel generator. Two numbers matter on any generator: peak watts, the short burst it can deliver when a motor first kicks on, and rated (or running) watts, what it can supply steadily. This one gives 12,000 peak and 9,500 rated watts on gasoline, or 10,800 peak and 8,550 rated watts on LPG. “Dual fuel” means it runs on either gasoline or liquid propane, which is handy because propane stores well and may be easier to find after a storm.
The listing names a 457cc four-stroke OHV engine with electric start, a powder-coated frame, drop-down handles, 10-inch never-flat wheels and an 8-gallon tank good for up to 12 hours at half load on gasoline. Outlets include four 120V 20A outlets, a 120V/240V 30A twist-lock, a 120V/240V 50A outlet and a 12V DC output. The title calls it transfer switch and RV ready and CARB compliant, which means it meets California’s emissions rules.
This is the one for a homeowner who plans to connect through a transfer switch (an electrician-installed switch that safely feeds your home panel) and wants the longest listed runtime among the big models. If you want quieter, electronics-friendly power, the PGD105TiSCO inverter is the alternative.
Pulsar PG1202SA 1200W Portable Generator for Light Camping Loads
Pulsar
Pulsar PG1202SA 1200W Portable Generator, 900 Running Watts, 71cc 2-Cycle Engine, 40:1 Fuel Mix, 120V & 12V Outlets, Recoil Start
Price and specifications are read from the Amazon product page and can change.
Pulsar PG1202SA 1200W Portable Generator
Best for: Tailgating and tiny camp loads
Pros
- Small, easy to carry
- 12V battery charging
- 120V outlet
Cons
- 2-stroke needs 40:1 fuel mix
- Not for air conditioners
The Pulsar PG1202SA 1200W Portable Generator sits at the opposite end of the lineup. It delivers 1,200 peak and 900 running watts from a small two-stroke engine; the title says 71cc while the specs say 69cc, so the listing is not consistent on that point. Two-stroke engines need oil mixed into the gasoline, here at a 40:1 ratio, which is an extra step first-time owners should know about.
It has recoil (pull-cord) start, a 1.1-gallon tank, a 120V outlet and a 12V outlet for battery charging. The listing states plainly that it is not meant to run air conditioners.
Think of it as a tailgating or campsite helper for a light, a fan or charging a battery. It will not run household appliances during an outage; for that, look at the larger models or a mid-size unit like the Pulsar 4000 watt generator.
Pulsar 1500 Watt Portable Quiet Inverter for Campsites
Pulsar
Pulsar 1500 Watt Portable Quiet Inverter Generator Gas Powered, Small Ultra Lightweight Quiet Generator for Camping, Tailgating, Home Backup
Price and specifications are read from the Amazon product page and can change.
Pulsar 1500 Watt Portable Quiet Inverter
Best for: Quiet camping and phone-charging power
Pros
- 62 dB rated noise
- Clean inverter sine wave
- Overload and short circuit protection
Cons
- 1,100 running watts only
- Listing omits runtime and weight
The Pulsar 1500 Watt Portable Quiet Inverter generator gives 1,500 starting and 1,100 running watts at a rated 62 dB. An inverter generator uses electronics to produce a smooth sine wave, which the listing describes as cleaner power than a traditional generator; that makes it a comfortable match for phones, laptops and other sensitive devices.
The listing mentions overload and short-circuit protection, wheels, 120V output at 60 hertz and a lightweight build, and it suggests home, RV and jobsite use as well as camping. It does not specify weight, tank size, runtime or start type.
Choose this Pulsar 1500 watt inverter if quiet matters more than power, for example at a campground. It is a better everyday camp companion than the PG1202SA thanks to its standard gasoline and inverter output, but neither small model replaces a 12,000-watt unit for home backup.
Pulsar 13,000-Watt Tri Fuel Generator for Maximum Output
Pulsar
Pulsar 13,000-Watt Tri Fuel Gasoline, Propane, Natural Gas, Portable Generator with Remote Start
Price and specifications are read from the Amazon product page and can change.
Pulsar 13,000-Watt Tri Fuel Gasoline
Best for: Maximum power with natural gas option
Pros
- 13,000 peak watts on gas
- Gas, propane or natural gas
- Remote, electric and recoil start
- CO sensor and GFCI outlets
Cons
- 5 hours at half load on gas
- Not an inverter
The Pulsar 13,000-Watt Tri Fuel Gasoline, Propane and Natural Gas generator (model PG13000TRCO in the description) is the most powerful model here. On gasoline it delivers 13,000 peak and 10,200 running watts; on propane 11,500 and 9,200; on natural gas 10,500 and 8,160. Natural gas can come straight from a home gas line if a professional connects it, so you are not refilling a tank during a long outage.
It uses a 500cc, 17HP OHV engine with remote, electric and recoil start. Outlets include four 120V GFCI outlets (which cut power if they detect a fault), an L14-30R and an L14-50R at 120/240V, and a 12V DC output. Extras listed are automatic voltage regulation, a CO sensor, low oil shutdown, a fuel gauge, 12-inch never-flat wheels and fold-down handles. The 8-gallon tank gives up to 7.5 hours at half load on gasoline.
This Pulsar 13000 watt tri fuel generator suits a household that wants the most wattage and the option of natural gas. It gives way to the G12KBN-SG if longer gasoline runtime matters more than extra peak power.
Pulsar PGD105TiSCO Tri Fuel Inverter Generator for Sensitive Electronics
Best for: Sensitive electronics during long outages
Pros
- Inverter power, 62 dB rating
- Three fuel types
- USB-A and USB-C outlets
- Up to 9 hours at half load
Cons
- Lower peak than 12,000W models
- Smaller 6.9 gallon tank
The Pulsar PGD105TiSCO Tri Fuel Inverter Generator combines three fuel options with inverter power. It makes 10,500 peak and 8,500 running watts on gasoline, 9,500 and 8,000 on propane, and 8,400 and 6,800 on natural gas, and the listing says it is safe for sensitive electronics and rated at 62 dB.
It has a 458cc EPA and CARB compliant engine, a 6.9-gallon tank good for up to 9 hours at half load, remote and electric start, a digital display, low idle control, a CO sensor and overload protection. Outlets are the widest here: USB-A, USB-C, four GFCI 120V 5-20R, an L14-30R and an L14-50R.
Pick the Pulsar PGD105TiSCO inverter if you want to keep computers, TVs and modern appliances running quietly. It gives up some peak power to the 12,000 and 13,000-watt models, so it is less suited to starting several big motors at once.
Pulsar 12,000W Dual Fuel Portable Generator for Easy Fuel Switching
Best for: Dual fuel home backup with fuel switching
Pros
- Switch & Go fuel changeover
- Electric start with recoil backup
- 3-in-1 digital meter
- 10-inch never-flat wheels
Cons
- Tank size misstated in specs
- Listing gives no runtime
The Pulsar 12,000W Dual Fuel Portable Generator, model PG12000B, shares its headline output with the G12KBN-SG: 12,000 peak and 9,500 running watts on gasoline, 10,800 and 8,550 on LPG, from a 457cc CARB-approved OHV engine.
Its signature feature is Switch & Go, which the listing describes as the ability to change between fuels, paired with electric push start and a recoil backup. It adds a 3-in-1 digital meter, drop-down handles and 10-inch never-flat wheels, with four 120V outlets, a 120/240V twist-lock, a 120/240V 50A RV outlet and a 12V DC output. The specifications list the tank volume as 457 cubic centimeters, which is clearly the engine size copied into the wrong field, so the listing does not really specify tank size or runtime.
This suits a buyer who likes a meter to watch output and a pull-start backup. If you want a clearly stated runtime and a transfer-switch-ready description, the G12KBN-SG is better documented.
How to Choose the Right Pulsar Generator
Add up your running watts. List what you must power in an outage and add the running watts; then check the one item with the biggest startup surge fits within peak watts. A 12,000-watt model gives headroom for a refrigerator, sump pump, lights and more at once, while the 1,200 and 1,500-watt units are for small loads only.
Pick your fuel. A dual fuel generator for home backup lets you switch between gasoline and propane. Tri fuel adds natural gas, which suits homes with a gas line. The PG1202SA needs premixed two-stroke fuel.
Decide on inverter or conventional. Inverters such as the PGD105TiSCO and the 1500 watt model are quieter and produce cleaner power. Conventional frame generators generally trade some refinement for raw output.
Check outlets and connections. For a transfer switch or RV, look for the 30A or 50A 240V outlets found on the four large models. If none of these sizes feels right, a middle option like a 6,500-watt portable generator may be a sensible compromise.
FAQ
What can a Pulsar 12000 watt generator run?
With 9,500 running watts on gasoline, it can typically handle several major appliances together, such as a refrigerator, sump pump, lights and a window unit, as long as the combined running watts stay within its rating.
What is the difference between the G12KBN-SG and the PG12000B?
Both list the same wattage and a 457cc engine. The G12KBN-SG lists an 8-gallon tank, 12-hour half-load runtime and transfer switch readiness; the PG12000B highlights Switch & Go fuel changing, a digital meter and recoil backup.
Which Pulsar generator should I buy for sensitive electronics?
The PGD105TiSCO is the large inverter here, and the 1500 watt model is the small one. Both produce clean inverter power.
Can I run a Pulsar generator on natural gas?
Only the 13,000-Watt Tri Fuel and the PGD105TiSCO list natural gas. Have a professional make the gas connection.
Can the Pulsar PG1202SA run an air conditioner?
No. The listing states it is not supposed to run AC units.
Is it safe to run a generator indoors?
No generator should run indoors or in a garage, because exhaust contains carbon monoxide. The CO sensors on the tri fuel models add protection, but always place the generator outside and away from windows.
