Comparsion Table

#1. WEN 56380i Gasoline Inverter Generator with Electric Start

The WEN 56380i is made with an extremely reliable four-stroke 212cc engine. This engine is an OHV with a single cylinder that is air-cooled. You can expect 3,800 watts of surge power and 3,400 watts of continuous rated power. This kind of power allows you to run your power tools, microwave oven, air conditioner, heater, and full-size refrigerator (not at the same time). This is perfect for RV enthusiasts and sailors of the deep blue.

It weighs 99-pounds wet making it on the heavy side. It has two handles on either side for two people to carry it. And it also comes with a nice handle so you could wheel it around with a couple of small plastic wheels, better than some that I've seen on the market.

The easy-to-understand control panel has a low-oil lamp and an overload alarm. This is an electric start model, so you don't have to worry about cranking it.

The ECO-MODE technology helps it conserve energy while keeping the noise level to about 57 dBA. That is pretty good for such a powerful machine. It is EPA and CARB compliant as well.

One cool feature of this generator is that you can connect two of them together to double your wattage. This is a 3,800-watt generator. So, by connecting two of them, you should be able to get 7,600 Watts.

Other features:

• Its 2.2-gallon gas tank is capable of running the generator for about 8.5 hours at half load.
• The generator is equipped with two USB ports (1-amp and 2.1-amp).

#2. Champion 200988 - Quiet 4,500-Watt Portable Inverter Generator

Introducing the New Champion Dual Fuel Generator, model 200988. This one's an enclosed inverter generator with an electric start. It's 4,500 watts starting (up to 37.5 Amps) and then 3,500 running watts (up to 26.3 Amps). It's got the Champion branded engine (model R210N-VP, four-stroke, 212cc). Run-on regular unleaded gasoline (I always run 91 non-oxy) or propane.

Note that when operating on propane, the running power is 3,150 watts.

Of course, for camping, portability is a big issue. And I'm already a little bit concerned at the 103-pound weight of this thing. But I don't think you can get a 4,500 watt or 3,500-watt generator that weighs much less than 100 pounds. So I'm going to have to just deal with it, and I'm sure that that won't be a problem.

Also, at the front of the generator, you have this flip-up carry handle. It's got an aluminum handle, not just plastic. This thing wheels around very easily, and it's super easy to do one-handed. There are all also two handles on the top here. These are powder coated. They just feel super robust.

It comes with:

• Two NEMA 5-20R Duplex Outlets
• One NEMA TT-30R RV Outlet
• One 12-volt DC Outlet
• One Parallel Port

#10. Briggs & Stratton 30736 - 3500 Watt Portable Generator with RV Outlet

Are you looking to power some of your tools or appliances? Better yet, looking for an affordable conventional generator that can power your RV’s 15,000 BTU air conditioner? Well, you might have to pay serious attention to the Briggs & Stratton 30736!

At a glance, this unit still is what you would consider a heavy piece of machinery. However, you might have an easier experience moving it around thanks to its set of never-flat tires. Let’s closely scrutinize why this unit might be the best buy at this price tag.

Operation & Ease of Use

This unit’s control panel presents you with amazing functionality, and it isn’t overly complicated to use. The multi-featured control panel rocks three household outlets – (2) 120V/20A Duplex (NEMA 5-20R), (1) 120V/30A (NEMA TT-30R) – Locking RV outlet.

This unit is equipped with circuit breaker protection to safeguard it in the case you overload the outlets and an automated low-oil shut-off system.

Given, the Briggs & Stratton 30736 is not a lightweight generator. Even though it weighs about 115lbs, it’s technically movable. That being said, you might want to use special equipment for any attempts to manipulate and transport it. The good thing is that it rocks 7” never-flat tires to assist you when moving it around.

CO Guard technology: advanced carbon monoxide detection system. The generator will automatically shut off if it's not in a well-ventilated area, and the CO2 concentration may be dangerous.

Noise Level & Power

The Briggs & Stratton 30736 is fitted with a powerful 208cc, OHV engine for a power yield of about 3,500 running watts and 4,375 surge watts. All thanks to its Power Surge Alternator, this unit produces short power surges that can power up your huge motor-driven appliances.

It’s quite unfortunate that the Briggs & Stratton 30736 doesn’t have quiet functionality. Even though the manufacturer doesn’t specify this conventional generator’s noise level, they went out of their way to fit it with a Super Lo-Tone muffler in an attempt to reduce its noise generation.

Verdict: Should You Buy It?

Bottom line, if you’re on the market looking for a huge fuel-efficient generator, just under $600, that packs the juice to power most, if not all, of your RV’s appliances – then, the Briggs & Stratton 30736 might be a good buy for you. In fact, the DuroMax XP5500EH is one of the other few models that have comparable levels of power for every dollar spent and functionality!
