#1. Yamaha EF4500iSE - Portable Gasoline Generator Review

Yamaha has a good track record of producing some of the most reliable and efficient portable generators in terms of functionality, durability and power efficiency.

The EF4500iSE does well to uphold this reputation. It's a powerful little generator that's capable of meeting most of the basic electric power needs while still being fuel-efficient and fairly silent, qualities that makes it one of the ultimate RV generators.

Featuring a 375cc OHV single four-stroke cylinder Yamaha engine, the EF4500iSE is capable of supplying sufficient power to run most domestic electrical equipment. The engine is able to deliver 4,000 watts of running power which can surge up to 4,500 watts.

The unit gives out cleaner electricity with a low harmonic distortion which is safe for sensitive electronic equipment, so it's really an ideal generator for an RV for powering your appliances.

It can power an RV 1000 watt microwave oven and 15,000 BTU air conditioner plus it's suitable for other sensitive electronic equipment like televisions, computers, satellite TV systems, and fridge, to name just a few.

The fuel tank has the capacity of 4.5 gallons which is sufficient to hold enough fuel to run the generator for around 15 hours at 25% load capacity. At 50% load, it will go for about 10 to 12 hours which is basically the range for most fuel tanks for generators of this size.

The tank will keep the machine running for nearly 7 hours at full load. Considering the fuel capacity and the run time, you are guaranteed sufficient power to keep your appliances running for at least a solid workday.

This simple fact makes the Yamaha EF4500iSE an ideal camping partner but also a perfect option for domestic use at home. It's even equipped with a low oil warning system that automatically shuts down the engine to protect it from exhaustion.

The engine is also designed to adjust to power requirements as it features the inverter technology. It can constantly run at an ultra-low speed of 1000 to 2600 rpm. The payoff for this slow engine speed is a reduction in fuel consumption as well as engine wear.

The generator can be turned on using an electric starter but even much better, Yamaha has included an optional wireless remote control that works from a distance of up to 66 feet away. It's a nice addition that allows you to start the generator more easily.

As with almost all of Yamaha's generators, this one is designed to ensure minimum noise. It has a noise block sound reduction system which combined with the slow engine speed makes it one of the few quietest generators on the market today.

It has a noise level of 58 to 60 dB when the engine is running at 25% load capacity. Therefore, it's very quiet for a generator of its size.

The only major setback though is that there is no recoil starter which usually serves as a nice back up should the electric starter fail.

This means you will have to ensure that the battery always has enough power so that you can be able to start the generator whenever a need arises.

Other than that, the Yamaha EF4500iSE is a powerful compact generator that's not only very portable but also very capable of generating power most efficiently.

If you own an RV or love comping and you want a reliable power source, then you might want to consider this Yamaha portable generator.

#2. DuroMax XP5500EH Dual Fuel Generator 5,500 Watt with Electric Start

The induction of innovative dual-fuel generators on the market today seemingly rubs on the market value flop of traditional gas-fueled generators. And for good reason!

Are you taking your family out into the wilderness for a weekend? Better yet, are you and family friends looking to tailgate at the kids’ football game? Well, it might be hard for you to find a portable generator with a better bargain and one that beats the wattage of the DuroMax XP5500EH.

At a glance, this model is enfolded in heavy-duty tubular-like frame constructs, four-point separate motor mounts, a wheel kit, and flip-up stow away handles. But as the rule clearly stipulates, it is sensible for you to do some due diligence before buying any piece of machinery. Here’s a closer scrutiny as to why the XP5500EH might be the perfect dual fuel unit geared towards your preferences:

What is in the Package?

Here’s what the manufacturer includes in the packaging:

  • DuroMax XP5550EH Dual Fuel Generator
  • Flip-Up, Stow-Away Handles
  • 8 Pneumatic Knobby-Style, Solid-Fill Tires
  • Generator Maintenance Tool Kit
  • User Manual

Operation & Ease of Use

The DuroMax XP5500EH is a compact generator that is fairly easy to use for experienced generator operators. To get it up and running, you just have to flick its ignition switch. Even though it doesn’t have a remote start feature, the good thing is that it still rocks the standard recoil starter; for use as backup in case the battery is low on charge.

The power panel of the XP5500EH features 3 AC outlets – (1) 120/240V 30A (L14-30R), Duplex 120V 20A (5-20R) GFCI. It also features a DC outlet – a 12V 8A receptacle that allows you to easily charge up your batteries. Note that the twist-lock L14-30R receptacle ensures that the DuroMax XP5500EH is transfer switch ready – you can connect it to a breaker box to power your RV.

You’ll find this portable generator’s data center on the control panel. Here, all the information you need of the lifetime run-time hours is displayed for your convenience. A voltmeter lets you monitor this DuroMax’s power yield at any one moment; a handy feature especially when you want to be hands-on with the unit’s status and activity.

A built-in fuel gauge ensures that you conveniently keep an eye on its gas-level. Additionally, this unit comes with a light indicator that lets you know when the oil level gets too low.

There are additional built-in safety features to keep this portable generator safe when you’re away. In case the oil level gets too low, or if this generator is somehow overloaded, it is designed to automatically switch off.

Even though the XP5500EH may be technically movable, you might want to keep in mind that it weighs in at 127lbs and therefore, any attempts to manipulate and transport it without using special equipment might be too far-fetched. That being said, its wheel kit and stoke-away, flip-up handles should compensate for this lack of maneuverability.

Noise Level & Power

All thanks to the dual fuel capability of this model, the versatile XP5500EH presents you with 120/240V of power. When the XP5500EH is gasoline-powered, it provides a power yield of about 4500 running watts and 5500 surge watts. On the flip side, when it’s propane-powered, it provides a power yield of about 4275 running watts and 5225 surge watts.

Case in point – if you are going camping or tailgating, this unit might allow you to simultaneously power a number of appliances, for example – a coffee maker, rice cooker, blender, toaster oven, slow cooker, mixer, satellite receiver, and a RV refrigerator.

*You might want to be advised that this DuroMax model is unsuitable for powering sensitive electronic devices because of its relatively high THD (<12%).

With this model’s 4-gallon fuel tank, you can expect it to present you with a run-time of about 9hrs at 50% Load when running on gasoline at a fuel consumption rate of about 0.44GPH. However, when the generator is running on propane, you can expect it to present you a run-time of about 8hrs at 50% Load at 0.56GPH.

For a portable dual fuel generator with its weight and wattage, it is rather silent in operation. Enjoying a noise rating of about 69dBA, the XP5500EH doesn’t trade off on noise generation for wattage.

Verdict: Should You Buy It?

All things considered, the DuroMax XP5500EH is an affordable and durable portable dual-fuel generator that presents you with a relatively good run-time. And – it’s not only reliable; the versatility that this DuroMax poses is a cut above its conventional gas-powered counterparts.

If you are an RV traveler looking to buy a dual fuel generator because of its ease of use, quiet operation, and impeccable safety features – then, the DuroMax XP5500EH might just be a good buy for you. Nonetheless, if power is what you are out for, why not have a look at the DuroMax Hybrid Dual Fuel XP12000EH?
