Description
Zoom on the Yamaha EF5500D
In summary, the Yamaha EF5500D is a portable generator especially useful for:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Homeowners in need of an emergency backup power for their essentials
- Professionals in need of safely powering high-intensity work or lighting equipment
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Yamaha EF5500D's design includes a gasoline-fueled 358 cc Yamaha MZ360 OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 4500W and also a peak wattage of 5500W.
The generator features a simple traditional pull-start mechanism. It is rated for a noise of 74.1 dBA (just slightly more noisy than a shower).
The fuel capacity of 6.9 gallons allows the EF5500D to operate for around 13.5 hours at 50% load with a full tank (fuel consumption around 0.51 GPH).
Outlets
The control panel includes the following 6 AC outlets:
While this Yamaha generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor. Besides, due to the featured twist-lock L14-30R receptacle, the EF5500D is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.
Portability
With its dimensions of L29.1 x W29 x H31.5 in, the conventional, open frame design of the Yamaha EF5500D offers stability and allows the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 216.1 lbs make it incredibly difficult to manually lift and transport. Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.
The generator comes with an additional safety feature, a lift hook on the top of its frame, which is helpful during its transport, loading and unloading.
Features
The control panel of the EF5500D includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the voltage and lifetime run hours.
In addition to this info, when the oil level is too low, you will be informed by the featured light indicator.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Watch system), which gives you a complete peace of mind when using it.
Yamaha's Oil Watch warning system gives you an extra peace of mind. This feature enhances long-term durability by preventing engine damage and costly repairs. Once the oil begins to run low, the generator automatically shuts off and cannot be re-started until oil is added.
It also includes a carbon monoxide sensor. This sensor is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).
Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Yamaha also included a tool kit in the EF5500D's packaging.
Emissions
The Yamaha EF5500D is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
Moreover, it features a spark arrestor, so it is adequate for use in forested areas.

The Yamaha EF5500D versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Yamaha EF5500D compare to generators of similar power (between 4000 and 5000 W).
- At a dry weight of 216.1 pounds, the Yamaha EF5500D is one of the heavier devices which can produce between 4000 and 5000 running watts. In terms of weight, one of the champions in their power range is the Pulsar PG5250, standing at just 99.5 lbs.
- Among the generators of a comparable running wattage, this generator with a lowest noise of 74.1 dBA can be judged as noisy. If noise emissions are important to you, one of the least noisy generators of this power range is the Yamaha EF4500iSE with only 58 dBA.
- As the EF5500D features an autonomy of around 13.5 hours at 50% load, it has a higher run time than an average generator of its power range. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Dewalt DXGN4500, reaching around 15 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator reaches an estimated fuel consumption of 0.51 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.33 GPH, the Pulsar PG5250B is a device you could look out for.
The bottom line
- CO Sensor
- GFCI Outlets
- High run time
- Decent fuel efficiency
- No electric start
- On the heavy side (216.1 lbs)
- On the noisy side (74.1 dBA)
