A Closer Look at the Erayak 4500PD
I’ve always appreciated inverters for their quiet operation, fuel efficiency, and clean power. All of my personal generators are inverters, and the Erayak 4500PD caught my eye because it offers some features that my current models don't have, making it worth a closer look.
One of the most impressive features is the automatic fuel switching. Unlike other generators that require manual input, the 4500PD automatically switches between gasoline, propane, and natural gas. When the pressure from the propane tank drops, it seamlessly switches to gasoline, allowing for continuous operation without any interruptions. This feature is not only convenient but also helps to maximize the generator's runtime by efficiently managing fuel sources.
The 4500PD is also equipped with advanced inverter technology, boasting a THD (Total Harmonic Distortion) of just 0.2% to 1.2%, which is significantly lower than the typical 1.9% found in power grids. This makes it safe for even the most sensitive electronics.
Despite its compact size and 149cc engine, this generator can produce a reliable 3500 watts of power, making it a leader in its class. Additionally, it features a 30 Amp RV outlet and parallel capability, enabling users to double the power output when necessary.
In summary, the Erayak 4500PD stands out as a versatile and efficient power solution that is well-suited for a variety of needs, from RVs to home backup power. Its intelligent fuel management system and superior inverter technology make it a reliable choice for anyone in need of portable power.
For those interested in a deeper dive into its performance and features, I have done a comprehensive review in his video. If you resonate with what you've read so far, be sure to check out mine full video review for more insights.

First: The Generator - Absolutely perfect. Compact, quiet, and weight is 1/2 that of other 4500W generators I looked at. It is truly hand portable and fits easily into the trunk of my car. I Have thoroughly tested it and it meets specification of 3500W for gasoline and exceeds specs for Propane. It Will run propane continuously at 3200W, spec is 3100W. Also, it is very well built, and operates and starts easily. I am very pleased with this purchase.
SECOND: The company--Erayak only has a small presence in the USA and don't look for a domestic phone number to call. However, there online support is really 24/7 and you will get a response within a few hours. I accidentally ordered a gasoline only generator (a layout issue with their online order form). As per their warranty, I returned it. I thought I would be charged about $100 for return shipping since it was my mistake. Instead, they immediately altered their web page to remove issue confused my ordering and refunded me the full price with no deduction for return shipping. Way to go Erayak!!! Five star product and five star company. By the way this is a genuine user response. They did a great job and deserve credit.
I purchased this for its fuel versatility. I've run my 4500PDE on propane and will test run on natural gas when I received the gas hose I've ordered. After set up the generator happily started right up using propane with the electric start. It's surprisingly light for a 4500 watt inverter but still considering ordering the wheel kit for the convenience. Also considering purchasing a second unit to parallel for 9000 watt output. I plugged in a 1200 watt heater to test surge and the generator adjusted quickly to the electric draw and ran consistently once achieved. So far I'm very happy with this purchase as my "go to" if propane and gasoline should be in short supply.
We bought this product for use during power outages during hurricanes in Florida . It is clean, easy to use, lightweight to move around and has enough power for our refrigerator, television, coffee pot and other low loads when we need them. We are using natural gas and bought the model with an electric start for ease of use.
I've been using the EYG4500PDE for several months now, and it's been a lifesaver. Whether I'm camping or need backup power at home, this generator handles everything with ease. The tri-fuel capability is amazing, and the transition between fuels is seamless. Highly recommend for anyone who needs reliable power on the go!
I have been looking for a generator for a while, after reading several reviews we decided to give this one a try due to the price and power combination. We bought this to use for one out of camping trips! We were not disappointed. The generator has amazing power. We were able to run the heater and several other plugs for multiple family members including two teenager, so you know it was running nonstop ;). The value for the money is amazing. I was satisfied with how long we ran it and we did not run out of propane. We camped for the weekend on one tank of propane, which wasn’t empty when we got home. It’s easy to use and I was able to carry it by myself and I am a 5 foot women. The weight of the generator is a mere 54 lbs compared to several others that are much heavier. This makes transporting it a lot easier. It has handles to make transporting it easily and carrying it easier.
The design is great has an easy-to-use knob and an easy pull to start. It was not difficult to start and never shut off. Also, when running some generators give off a heave odor. I could not even smell this one. the design is functional and esthetic. Easy fix you just switch it back. Enough power to run my fridge and deep freezer and also has the plug options for the larger appliances. Luckily we had this because a storm hit the following weekend and we lost power for a day. This was able to keep our deep freezer running and none of the food went bad. If you are looking for a generator to purchase this one would be a great buy. Would def recommend!
I was really impressed with the fuel efficiency of this generator. On a full tank of gasoline, I was able to get almost 16 hours of power at a low load. The smart fuel switching feature is also a great touch. It automatically switched to gasoline when my propane ran out, and I didnt have to do a thing!
This generator is everything I needed for my outdoor adventures. Its quiet, easy to transport, and powerful enough to keep all my devices running. The digital display is a nice feature that makes it easy to monitor everything. Definitely recommend it for camping, RVs, and even home backup!
Living in an area with frequent power outages, having a reliable generator is a must. The EYG4500PDE hasnt let me down. Its easy to start, runs quietly, and powers all of my essential appliances without any issues. Im really glad I invested in this tri-fuel generator!
