Pulsar Generator Reviews: 4 Popular Models Compared (2026)

Pulsar generators give you a lot of watts for your money. That is the whole appeal. A Pulsar usually costs less than a big-name rival of the same size, and many models run on two or even three fuels.

But a low price raises fair questions. Is the warranty any good? Is there a carbon monoxide shutoff? Can you get parts? And which of the many models should you choose?

This guide answers those questions honestly. We compared four popular Pulsar generators using the specs on Pulsar’s own website and on Amazon. Where the two sources disagree, we tell you. We have not tested these machines ourselves, and we say so clearly.

Who Is Pulsar?

Pulsar Power Equipment is a value-focused outdoor power brand. Its website lists far more than generators. You will also find power stations, lawn mowers, string trimmers, edgers, tillers, pressure washers and air compressors.

A few facts from Pulsar’s own website:

• Generator range: 36 models, from a 1,200-watt 2-cycle unit to a 17,000-watt tri-fuel inverter.
• Fuel types: gas only, dual-fuel and tri-fuel models, plus a line of inverters.
• Parts: the site has a parts store with a separate section for generator parts.
• Support: a toll-free phone line and a contact form for parts, service and warranty questions. The support center is open Monday to Friday, 8:30 a.m. to 5:30 p.m. Central Time.

Pulsar describes itself as headquartered in the United States. Its website does not say where each generator is built, so check the product label if that matters to you.

Why Do People Buy Pulsar Generators?

There are three honest reasons.

• Value. You tend to get more watts and more outlets for the money than with premium brands.
• Fuel choice. Many models are dual-fuel. Some have Switch & Go, which Pulsar says lets you change fuel without shutting the generator off.
• Big-generator features on mid-priced machines. The larger models include a 50-amp outlet, electric start and a digital meter.

And there are honest trade-offs.

• Support hours are weekdays only. A storm on a Saturday night means waiting until Monday.
• Warranty details vary. Pulsar’s site and some Amazon listings state different terms for the same model.
• Not every model has a CO shutoff. Look for “CO Sentry” in the name or the feature list.
• Not every model can be sold in every state. Some listings are marked as not CARB approved, which matters in California.

Key insight: with Pulsar, the generator is rarely the problem. The details are. Check the exact model, the warranty and the CO shutoff before you click buy.

The Pulsar Lineup Explained

Pulsar’s range falls into five groups.

The model names give you clues. On Pulsar’s site, a name ending in CO has CO Sentry. For example, the PG12000B and the PG12000BCO are the same size, but only the second is listed with the carbon monoxide shutoff. Names with iS are inverters. Dual-fuel names usually include a B, and tri-fuel names a T.

Pulsar Models Compared

Here are the five Pulsar generators discussed in this guide, side by side.

Two things stand out. First, the generators with a CO shutoff are the newer inverter models. Second, the big open-frame dual-fuel models list the longest run times.

Where Pulsar’s Website and Amazon Disagree

This is the part most reviews skip. When we compared Pulsar’s product pages with the Amazon listings, some details did not match.

Small differences in run time or engine size will not change your life. Two of these rows matter, though.

The warranty. Three years and one year are very different promises. Before you order a G12KBN, ask the seller which warranty applies and keep the answer in writing.

The fuel mix. A 2-cycle engine needs the right amount of oil in its gasoline. Too little oil can damage the engine. Do not rely on a web page for this. Use the ratio printed in the owner’s manual that comes with your generator.

What Size Pulsar Generator Do You Need?

Pick the size before you pick the model. It takes five minutes.

1. List what must run at the same time. In an outage that is usually the refrigerator, some lights, phone chargers and the furnace fan or a window air conditioner.
2. Add up the running watts. The label on each appliance shows the number.
3. Allow for motors starting. Refrigerators, pumps and air conditioners need a short burst of extra power.
4. Check for 240-volt loads. A well pump or a transfer switch needs a generator with a 120/240-volt outlet.
5. Use the rated watts, not the peak watts. The rated figure is what the generator can deliver hour after hour.

Here is how the four reviewed models map to real jobs:

• 900 rated watts (PG1202SA): lights, phone and laptop charging, a small TV or a fan.
• 3,200 rated watts (PGD40iSCO): an RV, or a refrigerator plus lights and electronics at home.
• 8,500 rated watts (PGD105TiSCO): most home essentials, including 240-volt equipment.
• 9,500 rated watts (G12KBN): most home essentials with room to spare.

Remember that propane and natural gas lower those numbers. Our free Generator Size Calculator does the sums for your own appliances, and What Size Generator Do I Need? explains the method.

Pulsar Generator Reviews: Four Models, One by One

Pulsar G12KBN review: big power on two fuels

The G12KBN is the Pulsar most people ask about. It is a large open-frame generator with a 457 cc engine and electric start. On gasoline it is rated at 9,500 running watts. On propane that falls to 8,550.

The outlet panel is a strong point. You get four 120-volt 20-amp outlets, a 120/240-volt 30-amp twist-lock outlet and a 120/240-volt 50-amp outlet. That 50-amp outlet lets a transfer switch use most of the generator’s power.

What is missing? Neither Pulsar’s page nor the Amazon listing mentions a carbon monoxide shutoff on this model. Pulsar sells a similar 12,000-watt generator, the PG12000BCO, with CO Sentry.

Pulsar PGD105TiSCO review: three fuels, quieter running

The PGD105TiSCO is the modern choice. It is an inverter generator, so Pulsar describes it as safe to use with sensitive electronics. It is rated at 62 dB. And it runs on gasoline, propane or natural gas.

It also has the features the G12KBN lacks. CO Sentry is built in. A remote fob is included. The panel has four GFCI 120-volt outlets, a 120/240-volt 30-amp outlet, a 120/240-volt 50-amp outlet and two USB ports.

The price of that flexibility is output. On natural gas the rated power is 6,800 watts, compared with 8,500 on gasoline.

Pulsar PGD40iSCO review: light, quiet and RV friendly

The PGD40iSCO is a small inverter with a big number on the side. It gives 4,000 peak watts and 3,200 rated watts, yet it weighs only about 47 pounds. Pulsar rates it at 59 dB.

The Amazon listing says it suits air conditioners up to 13,500 BTU, which is the common RV size. Two units can also be linked in parallel for more power.

The weak spot is the tank. It holds one gallon, which gives roughly 4 to 4.5 hours at half load. For an overnight run you will be refueling.

Pulsar PG1202SA review: tiny, simple and limited

The PG1202SA is the smallest Pulsar. It weighs 35 pounds and makes 900 running watts. That is enough for lights, chargers, a small TV or a fan.

It is important to understand what it is not. The Amazon listing states plainly that it is not meant to run air conditioners. It has a 2-cycle engine, so you must mix oil into the gasoline every time you fill it. And it has no CO shutoff listed.

Pulsar also has an older mid-size dual-fuel model on Amazon, the PG10000B16. Its listing states 8,000 rated watts on gasoline and 7,000 on propane. Note that it is marked as not CARB approved, and it no longer appears on Pulsar’s own generator page.

Dual-Fuel and Switch & Go, Explained

A dual-fuel generator can burn gasoline or propane. Each fuel has a job.

• Gasoline makes the most power and is easy to buy. It goes stale in a few months unless you treat it.
• Propane stores for years and is often still on the shelf when gas stations have run dry. It makes a little less power.
• Natural gas, on tri-fuel models, never needs refilling. It makes the least power of the three.

Switch & Go is Pulsar’s name for changing fuel while the generator is running. Pulsar describes it as switching between fuel sources without shutting the generator off. That is useful at night. When the gasoline runs low, you can move to propane without a blackout in the house.

One caution. Always follow the steps in the owner’s manual when you change fuels. The order of the valves matters.

Safety: CO Sentry, Placement and Your Home’s Wiring

CO Sentry is Pulsar’s carbon monoxide sensor. Pulsar says it shuts the generator down automatically if dangerous levels of carbon monoxide are detected. Two of the four generators reviewed here have it.

Whether your generator has a sensor or not, the same rules apply.

If you plan to feed your home’s panel, tell your electrician exactly which generator you have. Outlet type, wattage and the way the generator’s neutral is wired all affect how the transfer switch should be set up. That is a job for a professional, not a weekend experiment. Our generator safety tips cover the rest.

Warranty, Parts and Support

This is where a budget brand deserves a careful look.

• Warranty length differs by model. Pulsar’s product pages state a 3-year limited warranty for the PGD40iSCO and PGD105TiSCO, 3 years for the G12KBN and 1 year for the PG1202SA.
• Sources can disagree. The Amazon listing for the G12KBN mentions a 1-year limited warranty. Ask before you buy.
• Parts are sold direct. Pulsar’s website has a parts store with a generator section, and you can search by product, part or model number.
• Support is by phone or contact form. Hours are Monday to Friday, 8:30 a.m. to 5:30 p.m. Central Time.

Our advice is simple. Take nothing on trust. Keep your receipt, save the listing, read the warranty statement in the box, and note the model and serial number on the day the generator arrives.

Fuel, Storage and Maintenance

A low-cost generator can last for years if you look after it. Most failures come from stale fuel and skipped oil changes.

• Change the oil on schedule on 4-stroke models. The manual gives the hours and the oil type.
• Mix fuel correctly on the PG1202SA. Use fresh gasoline and 2-cycle oil at the ratio in your manual, and mix it in a separate can.
• Treat stored gasoline with a stabilizer such as STA-BIL Storage.
• Start it once a month. Let it run for a while with something plugged in.
• Look after the battery on electric-start models. A small maintainer keeps it ready.
• Store it dry. Our guide on how to store a generator walks through every step.

Keep our generator maintenance checklist with the manual. If the generator will not fire up after storage, see why a generator won’t start.

Common Mistakes When Buying a Pulsar Generator (and the Fix)

Pro Tips for Pulsar Owners

• Write down the model and serial number and keep them with the receipt. Support will ask for both.
• Order wear parts early. A spare spark plug and air filter cost little and save a week of waiting.
• Keep a full propane cylinder in reserve if you own a dual-fuel model.
• Run it under load each month. A generator that only idles does not get a real test.
• Fit a battery maintainer on electric-start models.
• Plan for weekday support. Solve small problems before storm season, while the phone line is open.
• Use a generator cover or tent made for running in rain. Never run it inside to keep it dry.

What Owners Say, and Three Typical Buyers

Owner reviews on Pulsar’s own product page for the G12KBN repeat a few themes. We cannot verify them, but they are worth knowing.

• Storm use. Several owners describe buying it for long outages in hurricane areas.
• Monthly starts. More than one owner says that starting it every month prevents hard starting later.
• Noise. One owner describes it as not the quietest generator, but acceptable when placed well away from the house.
• Batteries. One long-term owner reports that the starting battery was the only part replaced.

The three buyers below are examples to help you choose. They are not quotes from real people.
