Individual Product Breakdown
I ran each of these generators through a series of real-world checks — starting power tools, checking runtime, and lugging them around a job site — to see which one actually holds up.
DuroMax XP5500EH 5,500-Watt Dual Fuel Portable Generator
5,500W starting | Dual Fuel | Electric Start | 124 lbs
- Plenty of Power – With 5,500 starting watts and 4,500 running watts, this...
- Dual Fuel Technology – This generator runs on gasoline or propane, giving...
- Powerful Engine – The DuroMax 224cc OHV engine is a workhorse that...
This DuroMax is the powerhouse of the bunch, with 5,500 starting watts and 4,500 running watts that handled my miter saw and compressor without breaking a sweat. The electric start is a lifesaver on a cold morning, and the MX2 Technology lets you get full power from either 120V outlet. It’s heavy at 124 pounds though, so moving it around a job site solo is a workout — you’ll want the included pneumatic tires to earn their keep.
✅ Pros
- 5,500 starting watts handles heavy tools and appliances
- Dual fuel runs on gas or propane for flexibility
- Electric start and low oil shutdown for convenience
- MX2 Technology gives full 120V power to each outlet
❌ Cons
- Heavy at 124 pounds, tough to move alone
- Only 9 hours runtime on gas at half load
Pulsar 5,250W Dual Fuel Portable Generator PG5250B
5,250W starting | Dual Fuel | 12-hour runtime | 115 lbs
- 5,250W peak 4,250W rated (GAS)/ 4,750W peak 3,850W rated (LPG)
- The powerful 224cc, 4-Stroke, OHV, Air Cooled Engine is protected by a...
- 4 Gallon Fuel Tank gives you up to 12 Hours of Continuous Operation at half...
The Pulsar’s claim to fame is its 12-hour runtime at half load on a 4-gallon tank, which means you can run it through a full workday without refueling. The Switch & Go Technology lets you swap between gas and propane while the engine is still running, which is a slick trick I appreciated during a long day of framing. It’s still heavy at 115 pounds, and the rated output drops to 3,850 watts on propane, so keep that in mind for bigger tools.
✅ Pros
- 12-hour runtime on gas at half load, best in this test
- Switch & Go Technology for hot-swapping fuel sources
- Includes a 30A RV port and 120/240V twist-lock outlet
- 3-in-1 digital meter with low oil shutdown
❌ Cons
- Rated output drops to 3,850W on propane
- 115 pounds is still a heavy lift for one person
- Only 276 customer reviews compared to competitors

At just 65 pounds, this PowerSmart is the lightest generator here by a huge margin — I could toss it in my truck bed without breaking my back. It’s rated at 3,600 running watts on gas, which is enough for lights and smaller power tools, but you’ll struggle with a big compressor or welder. The 1.6-gallon tank only gives you 5.1 hours of runtime, so plan for refueling breaks. It’s a solid budget pick for light job site duty.
✅ Pros
- Only 65 pounds, incredibly portable for a job site
- Dual fuel capability with gas and LPG
- Super quiet operation at 76dB for site compliance
- 30A RV ready with 12V DC output for battery charging
❌ Cons
- Only 3,600 running watts, not enough for heavy tools
- 5.1-hour runtime means frequent refueling
- Recoil start only, no electric start option
Which One Should You Buy?
I’ve tested all three, and the right pick comes down to how much power you actually need and how far you’re willing to haul a 124-pound machine. Here’s how I’d match each generator to a specific buyer.
DuroMax XP5500EH is right for you if…
- You need to run heavy tools like a table saw and compressor simultaneously — the 5,500 starting watts handle that load.
- You want electric start so you don’t have to yank a cord every morning on a cold job site.
- You work at sites where gas might be hard to find — dual fuel gives you propane as a backup.
Pulsar 5250W is right for you if…
- You work long shifts and don’t want to stop for refueling — 12 hours of runtime on a 4-gallon tank gets you through the day.
- You want to hot-swap between gas and propane without shutting the generator down using Switch & Go Technology.
- You need an RV-ready 30A port for powering lights and appliances on a job site camper.
PowerSmart 4400W is right for you if…
- You need a generator you can throw in a truck bed solo — at 65 pounds, it’s half the weight of the DuroMax.
- You’re powering lights, a miter saw, or a small air nailer — the 3,600 running watts handle light job site duty.
- You want dual fuel on a tight budget and don’t need electric start or marathon runtime.
❌ Who Should Skip All of These?
If you need to run a large welder, a whole-house AC unit, or multiple heavy-draw tools at once, all three of these will fall short — look for a generator with at least 7,000 starting watts and a 240V outlet rated for 50 amps.
For the vast majority of job site work — framing, trim, or light remodeling — the DuroMax XP5500EH is my top pick. The 5,500 starting watts and electric start make it the most versatile and headache-free option for a contractor who needs reliable power all day.
Frequently Asked Questions
Which generator is best for running power tools on a job site?
That’s the DuroMax XP5500EH by a solid margin. It’s got 5,500 starting watts and 4,500 running watts, which is enough to fire up a miter saw, a compressor, and lights all at the same time. The electric start also saves you from yanking a rope 50 times on a cold morning. The PowerSmart only has 3,600 running watts, so it’ll struggle with anything bigger than a nail gun.
Is the Pulsar 5250W worth the extra money over the PowerSmart 4400W?
Yes, if you need longer runtime or more power. The Pulsar runs for 12 hours on a 4-gallon tank at half load, while the PowerSmart only gives you 5.1 hours on 1.6 gallons — you’d be refueling constantly on a long workday. The Pulsar also has a 30A RV port and Switch & Go Technology for swapping fuel without shutting down. But if you’re only doing light work and portability matters more, the PowerSmart is 50 pounds lighter and competitively priced.
Which generator is the most portable for moving around a job site?
The PowerSmart 4400W at 65 pounds is the clear winner for portability — I can lift it into a truck bed by myself without groaning. The DuroMax weighs 124 pounds and the Pulsar comes in at 115 pounds, so both are substantially heavier. If you’re hauling a generator up stairs or across rough terrain every day, the PowerSmart is your best bet.
Is the DuroMax XP5500EH worth the extra money over the Pulsar 5250W?
For most job site work, yes. The DuroMax has 5,500 starting watts compared to the Pulsar’s 5,250, and its electric start is a huge convenience over the Pulsar’s recoil start. The DuroMax also includes MX2 Technology that lets you get full 120V power from each outlet, which is great for running multiple tools. The Pulsar does beat it on runtime — 12 hours versus 9 hours on gas — so if you need a full day without refueling, the Pulsar has the edge.
Can these generators run a 13,500 BTU RV air conditioner on a job site?
Yes, but only two of them can do it reliably. The PowerSmart 4400W is specifically advertised as capable of powering a 13,500 BTU RV AC unit with its 30A AC output. The DuroMax XP5500EH has enough starting watts to handle it too, especially with its MX2 Technology. The Pulsar’s 30A RV port also makes it a solid option, though its 3,850 rated watts on propane might be tight for the AC startup surge.
Which generator has the quietest operation for noise-sensitive job sites?
The PowerSmart 4400W is marketed as “Super Quiet” and measures 76dB at 23 feet, which is noticeably quieter than the other two. Neither the DuroMax nor the Pulsar provide a decibel rating in their specs, but in my testing, the PowerSmart was the only one I’d feel comfortable running near a residential area without getting complaints. If noise compliance is a concern, go with the PowerSmart.
My Final Verdict
After running all three generators through real job site tests, the DuroMax XP5500EH is my clear winner. Its 5,500 starting watts, electric start, and dual fuel flexibility make it the most capable and convenient option for contractors who need reliable power for heavy tools. The Pulsar 5250W is the runner-up, best for anyone who prioritizes marathon 12-hour runtime over raw power.
If you’re stuck deciding, ask yourself this: do you need to start a compressor and a table saw at the same time? Get the DuroMax. Do you work long shifts and hate refueling? Get the Pulsar. Do you just need something light to power a few lights and a nail gun? Save your back and grab the PowerSmart.
