Comparison Overview

Analysis by AJ Quick
Mechanical engineer and founder of RightGenerator

The biggest difference between these two inverter generators comes down to power versus portability. The Briggs & Stratton P4500 delivers 3700 running watts and 4500 starting watts, giving it a significant edge for running larger appliances or multiple devices at once. The WEN 56360iX offers 2900 running watts and 3600 starting watts, which is still enough for many common needs but may fall short if you're powering a large window AC unit or several tools simultaneously.

Portability is where the WEN pulls ahead dramatically. At just 46.3 pounds, it's less than half the weight of the Briggs & Stratton, which tips the scales at 104 pounds. That's a meaningful difference if you're loading a generator into a truck bed, hauling it to a campsite, or storing it on a shelf. The Briggs & Stratton also wins on noise, rated at 60 dB compared to the WEN's 65 dB, and it offers considerably longer runtime at 16 hours at 25% load versus the WEN's 5 hours at 50% load. Both units are inverter generators with clean power safe for sensitive electronics, and both carry a 3-year warranty.

If you value easy transport and lighter weight above all else, the WEN is the natural pick. If you need more power and longer runtime, the Briggs & Stratton is the stronger choice.

Key takeaways

  • WEN 56360iX weighs just 46.3 pounds, less than half the Briggs & Stratton's 104 pounds
  • Briggs & Stratton P4500 delivers 3700 running watts versus the WEN's 2900 running watts
  • Briggs & Stratton runs up to 16 hours at 25% load for overnight home backup
  • WEN offers 5 hours of runtime at 50% load in a much lighter package
  • Briggs & Stratton operates at 60 dB, quieter than the WEN's 65 dB rating
  • Both are inverter generators with clean power and 3-year warranties

Best use cases

Choose the WEN 56360iX if you need a generator you can easily carry and move around without help. At 46.3 pounds, it's genuinely portable in a way that the 104-pound Briggs & Stratton simply isn't. This makes it a strong option for camping trips, tailgating, or any situation where you'll be lifting and transporting the unit frequently. Its 2900 running watts can handle essentials like a small refrigerator, phone chargers, lights, a laptop, and a portable fan. It's also a reasonable choice for light home backup during short outages, though the 5-hour runtime at half load means you'll be refueling often. If your power needs are modest and convenience is a top priority, the WEN delivers solid value in a compact package.

Choose the Briggs & Stratton P4500 PowerSmart if you need more sustained power for bigger jobs. With 3700 running watts and 4500 starting watts, it can handle higher-demand appliances like a medium window air conditioner, a sump pump, or a small power tool alongside other household essentials. The 16-hour runtime at 25% load is a major advantage for overnight use during power outages, meaning you can keep a refrigerator and a few lights running through the night without getting up to refuel. The quieter 60 dB operation is also a plus for RV parks or neighborhoods where noise matters. The tradeoff is real, though. At 104 pounds, this is not a generator you'll want to carry any distance without wheels, and loading it into a vehicle takes some effort. It's best suited for situations where it stays relatively stationary, like a home driveway, an RV hookup, or a fixed job site location.

Verdict & recommendation

These two inverter generators serve overlapping but distinct audiences. If your priority is easy portability and you only need to power a handful of smaller devices, the WEN 56360iX's featherweight design at 46.3 pounds makes it remarkably convenient. It's the kind of generator you can grab with one hand and toss in the car.

If your priority is running more appliances for longer stretches, the Briggs & Stratton P4500 PowerSmart's 3700 running watts and 16-hour runtime give it a clear practical advantage for home backup and extended use. You'll sacrifice easy mobility, but you gain the ability to keep your household running comfortably through a long outage.

Both carry the same 3-year warranty and both produce clean inverter power. Your decision should come down to whether you value grab-and-go lightness or the extra watts and endurance to handle bigger loads.

Summary
The Briggs & Stratton 30814 P4500 PowerSmart is a 3700-watt inverter generator built for users who need reliable backup power without the noise of traditional models. At 60 decibels, it runs quiet enough for residential neighborhoods and campgrounds, making it suitable for homeowners managing outages, campers extending trips, and outdoor enthusiasts who cannot tolerate generator noise. The 4500-watt peak output handles startup surges for larger appliances like air conditioning units or power tools, while the 3700-watt running capacity sustains continuous operation. With a 3.5-gallon fuel tank and 16-hour runtime at 25% load, users can power essential devices through a full night or longer without refueling. The inverter technology produces only 3% THD, which means laptops, smartphones, and other sensitive electronics charge safely without risk of voltage spikes or damage.
The WEN 56360iX is a 3600-watt RV-ready portable inverter generator designed for clean and quiet power, featuring a 149cc engine, fuel shutoff, and a CO shutdown sensor.
