High-Output Capacity


The e4500 Dual Fuel etrailer generator produces 4,500 watts of power to get you up and running whether you're at the campsite, at the worksite, or faced with an emergency. This powerful generator comes with (2) 120V outlets for powering household appliances, tools, and electronic devices. It features (1) 120V L5-30R twist-lock outlet for large appliances and motorized tools with greater electrical demands. Lastly, it has (1) 120V TT-30R outlet for a RV connection, ensuring you'll have access to electricity no matter where you take your RV or if there's a power outage at the campground.

Easy Electric Start Engine

The generator's engine is designed to start up easily so you can power up faster and without hassle. The key to this easy startup is the electric starter. With this starter, turning on your generator becomes remarkably easy and worry-free. Simply turn the fuel valve to "on" and flip the engine switch to the "run" position. Then, push the battery power restore switch for a few seconds and release. At the push of a button on the control panel, the generator will fire up and be ready to go.

Before starting your generator, ensure nothing is connected to the outlets. Start your generator and let the engine run for a few minutes to warm up and stabilize. Check to make sure the circuit breaker is in on position before continuing. Once the generator is up and running, you may connect your electrical loads. To follow the recommended order of operation, connect the device with the highest starting watts first, like your air conditioner or refrigerator, and work your way down to the device with the lowest starting watts. By connecting devices in this order, you can make the most of your generator's capacity through connecting high wattage loads when there is more power available.

Dual Fuel Capability

dual fuel selector

For flexibility and convenience during road trips or in an emergency, this generator can use gasoline or propane to power the engine. In addition, using propane as an alternative to gasoline is a cleaner option for the environment. However, while using propane the power output slightly decreases compared to gasoline.

  • Starting (surge) power output:
    • Gas: 4,500 watts
    • Propane: 4,050 watts
  • Running (rated) power output:
    • Gas: 3,600 watts
    • Propane: 3,250 watts

dual fuel propane connection

This generator includes a 5' LPG hose with regulator for connecting to a propane tank. Once you have connected your generator, turn the fuel selector switch to the LPG position. After that, you can start the generator with the push button electric start or pull start.

Safety Features

The e4500 Dual Fuel generator comes with a number safety features designed to protect both you and the generator itself. The 3-in-1 Data-Minder monitors voltage, frequency, and running hours. Simply press the select button to switch the information on the digital display.

When the generator is low on oil, a light-up indicator flashes and the engine will automatically shut down to prevent damage. If an overload is detected, either by exceeding the generator's limits or a power surge, the circuit breaker will stop supplying power to the connected devices. A built-in spark arrester helps prevent any sparking that might burn someone or start a fire, protecting both you and the environment. This arrester has been certified by the USDA Forest Service. Also, an automatic voltage regulator assists in minimizing voltage fluctuations which helps to maintain a steady flow of electricity.

Choosing a Generator

To choose a generator that meets your needs, you must match the size of the generator (that is, the starting output and running output in watts) with the electrical demands of the equipment that you want to operate.

Power Demands

Starting (surge) wattage is the power a device requires at startup. Running (rated) wattage is the power needed to keep the device running. A large appliance with an electric motor such as a furnace, refrigerator, air conditioner, or washing machine may require 2 to 3 times more starting wattage than running wattage.

It is always best to start your generator with no load connected, then add each device one at a time. Additionally, a good practice to consider is connecting your devices in order from highest starting watts to lowest starting watts. As you connect and start devices, your available wattage decreases. This order of operation allows you to start devices with the highest power demands when there is more power available.

Will This Generator Run My RV Air Conditioner?

At etrailer, we perform numerous tests on generators to put them through real-world experience. An extensive part of this testing includes starting and running RV air conditioners. The following table will help you decide if the e4500 Dual Fuel generator has enough power to handle this critical function in your RV.

* The starting wattage on air conditioners can vary greatly depending on several factors, including the assistance of built-in capacitors and cold starts. Because of this, we can't list a standard starting wattage as every application can be different.

Determining Your Power Needs

When choosing a generator, knowing the amount of power you will need is crucial to your decision. Whether you are preparing for an emergency situation at home or taking a weekend trip in the RV, planning out your application is essential. The two calculations below provide power estimations that will help point you to a generator that is right for your needs.

Industry Standard Calculation

The Industry Standard Calculation is a quick and easy way to determine your required wattage. It may provide some padding in your wattage requirements, which could give you more power than you actually need, but you shouldn't have to worry about not having enough power. The following steps will help you quickly calculate the correct size generator to meet your application.

As stated earlier, you should always start your generator without any load, and then connect each device one at a time. The following calculation requires this approach to work. However, using this calculation removes the worry of connecting devices in a certain order.

1. Determine the starting watts and running watts for the devices that you want to plug into the generator.

a. Find the starting (surge) watts and running (rated) watts for each device that you want to plug into the generator. Look for a sticker or plate on each device or check your owner's manuals.

b. If your device or manual only shows amps and volts, watts can also be determined through a simple formula. (Amps x Volts = Watts)

c. List all of your starting watts and running watts as seen in Table 1 below.

Table 1

Example DevicesStarting WattsRunning Watts
Air compressor2,0001,000

2. To find the total starting watts required, add the starting watts for the device with the highest value to the running watts of all the other devices from Table 1.

2,000 + 800 + 1,000 + 400 = 4,200 total starting watts

3. To find the total running watts, add all of the running watts together from Table 1.

1,000 + 800 + 1,000 + 400 = 3,200 total running watts

To run all of these devices simultaneously, you would require a generator with at least 4,200 starting watts and 3,200 running watts.

Advanced Precise Calculation

While the method for calculating your power needs outlined above will work, it isn't the most precise. If you aren't afraid of doing a little more math, you can use the Advanced Precise Calculation to get a more accurate idea of how much power you will need and potentially save yourself some money. Because the calculation above pads in enough power to ensure you can start your devices in any order, it may point you to a bigger and more expensive generator than you need. However, by following the more regimented, order-of-operations calculation below, you'll get a much more precise idea of how much power you need, which could in turn point you to a smaller and less expensive generator.

Again, you should always start your generator without any load, and then connect each device one at a time. The following calculation also requires that you start your devices in order from highest starting watts to lowest starting watts. When you connect devices in this order, you can start high demand devices when there is more power available.

1. Determine the starting watts and running watts for each device that you want to plug into the generator.

a. Find the starting (surge) watts and running (rated) watts for each device that you want to plug into the generator. Look for a sticker or plate on each device or check your owner's manuals.

b. If your device or manual only shows amps and volts, watts can also be determined through a simple formula. (Amps x Volts = Watts)

c. List out these devices from highest starting watts to lowest starting watts as seen in Table 2 below.

Table 2

Example DevicesStarting WattsRunning Watts
Air compressor2,0001,000

2. To find the total running watts, add all of the running watts together from Table 2.

1,000 + 800 + 1,000 + 400 = 3,200 total running watts

3. In Table 3, shown below, the values from Table 2 are used to calculate the highest total starting watts required as devices are connected and running. This number represents the highest power requirement you will encounter as you connect all of your devices to the generator. To find this, add the starting watts of each new device you connect to the combined running watts of all connected devices. The highest of these numbers will be the total starting watts required. And again, remember to always connect devices in order from highest starting watts to lowest starting watts.

Table 3

DeviceStarting WattsRunning Watts of All Connected DevicesTotal Starting Watts Required
1. Air compressor2,000 +0 (nothing connected)= 2,000
2. Refrigerator1,600 +1,000 (air compressor)= 2,600
3. Microwave1,000* +1,800 (air compressor + refrigerator)= 2,800
4. Blender850 +2,800 (air compressor + refrigerator + microwave)= 3,650

* Even though the microwave does not have starting watts listed, you have to account for the power needed to actually run it.

850 + 2,800 = 3,650 highest total starting watts required

In order to run all of these devices simultaneously, you would require a generator with at least 3,650 starting watts and 3,200 running watts. The starting watts are determined by the highest total starting watts required during the calculation in Table 3/Step 3. The running watts are determined by the total running watts from Step 2.

Video Transcript for etrailer 4,500-Watt Portable Generator Review

Speaker 1: Today we're gonna be taking a look at the etrailer 4500 watt portable generator, part number 333-0005.When choosing a generator, you'll want one that meets your electrical demands. Some things to consider are your starting watts and your running watts. Starting watts is power that your device or appliance needs when first turning it on, and running watts is power required to keep that device on.Some larger appliances, like your air conditioner, refrigerator, and washer and dryers require up to 2 to 3 times more starting watts than running watts to turn one. This means that the wattage will spike when powering your device on, and then drop to a lower wattage while running. One example would be when you're home and you turn on the vacuum cleaner, and the lights dim. Another way to think about it is water pressure.

When you're in the shower, and somebody turns on the sink or flushes the toilet, the water pressure drops.Another thing to consider is how many different devices or appliances you'll be running simultaneously. For example, your air conditioner, refrigerator, microwave, coffee pot, TV, radio, and all of your lights. It all adds up. You'll wanna be sure your generator can handle the combined wattage.This etrailer generator is gonna be great for the campsite, the job site, and emergency situations. It's gonna be ideal to use it with your RV, camper, power tools, or any other electrical tools or appliances.

While it does run on regular gasoline like most generators, one of its best features is its compatibility with propane, so it's a duel fuel system.Being able to run on propane can be highly beneficial. For one, it has a longer shelf life than gasoline, which degrades over time. It won't be contaminated, or full of carbon deposits, if not regularly used. So, for example, if you're someone who doesn't camp as frequently, you don't have to worry about the propane going bad.Another thing to consider is when a catastrophe strikes. Things like electrical outages, ice storms, and hurricanes.

Propane is easier to get a hold of, and it's available when gas pumps aren't.One thing to keep in mind, when running your generator on propane, it may not be as efficient in sub zero temperatures.Lastly, propane is environmental friendly. It's clean burning, and produces a low amount of carbon monoxide compared to other fuels.While you may like one fuel source more than the other, the nice thing is you get both options if the other is not available.When using your generator, and choosing your fuel source, one thing to keep in mind is that the on-board gas tank holds five gallons, whereas if you we're to use the propane, you determine the tank size.It's a 5 horsepower, four-stroke engine, that features an electric start, and a manual pull start. On board it features two 120 volt 20 amp common household outlets, 120 volt 30 amp RV outlet, and 120 volt 30 amp twist lock outlet. All outlets are fuse protected, and the reset switches are located here and here. It also has a three in one data monitor.

It's gonna show us our volts, our frequency, and our hours of use.Here we have the selector switch for our gasoline and propane. It's easy to operate, and it's easy to read.Here we have the LPG inlet for our propane, and the regulator and hose is included.Surrounding the engine and fuel-tank is a steal tubular frame. This is gonna give it strength and durability. Integrated within the engine and frame are four rubber isolators. This is gonna cut down on vibration and noise when the engine is running.It includes rubber coated wheels, and a handle with a pad for easy toting.The rubber feet on the bottom of the frame are gonna help stabilize our generator when parked. This too is also gonna help cut down on vibration.The exhaust features spark arrester. This is gonna prevent any flammable debris from exiting the generator.Now that we've got all the features, I'll go ahead and show you how to set it up. I've already gone ahead and removed it from the box, as you can see, the next step is to remove the shipping brackets underneath the generator, and this has to be done before you add any gasoline or oil. So what we can do is grab the handle, and we're gonna turn it up and rest it on its side.So here on the underside of the generator, the shipping brackets are red. It does include the wrenches to remove these. There's a nut on the back side, we'll just line it up, get them loose, and take them off.Now you can discard those brackets, we will not be needing them, and we're ready to turn the generator back over.Our next step is to connect our battery, we can push the wire through our cover, remove the hardware, and now our battery, we can remove that protective cover. We'll just line it up, put our hardware back in place. Once you've got it nice and secure, take our cover, and put it over the top.Next let's fill the oil. The oil filler cap is located over here, to the left of the battery. Let's take that out. I'd like to point out that it also doubles as a dipstick. We can take our included funnel, push that in, and pour in our included oil.Once it's filled up we can just use a little cloth, clean up any oil that we may have spilled, and put our cap back on.Now if you're using gasoline, now is the time to fill it up. It takes five gallons of regular, unleaded gasoline. We'll take off our cap, and begin fueling up. Once we're full, we can put our cap back on.Once you've got it all fueled up, you're ready to go. If you'll be using propane, you'll need a propane tank, and you'll also need to connect your hose and regulator. The hose connects right here on your generator. You'll need to provide your own wrench to tighten it down.The regulator connects to your tank, and we can just tighten that down by the large knob with our hand.Once you figure out which source you're going to use, you'll just need to select it. Since we'll be operating propane first, we'll turn it to propane, and we'll wanna make sure our tank is also open.From there, the rest of the start up procedure is the same, whether you're using gasoline or propane.For starting, you'll wanna set your choke to the starting position. Then we can just hold down our start button until the engine gets started. After that, we'll wanna turn our choke to the run position.If it seems like it wants to start, you can just go ahead and change the choke to the run position, and then try again. It should start right up.Once the light turns green, we're ready to plug in.With my generator running, I can operate my slide out, my lights, my microwave, and most importantly, my air conditioning. Here I am inside my camper, my generator is right outside, and I'm averaging about 66 decibels.Here outside next to the generator, I'm averaging about 88 decibels.To kill the engine, you can turn it to the off position. Now let's try it with gasoline. So then we'll just repeat our steps.With it running on gasoline, our decibels go up to 89.To perform some regular maintenance, I'd like to point out that your air filter is located on this side, next to your pull cord. To remove it, you'll need to take off the cover first. There is a clip on both the top and bottom. Take those off, then you have access to the actual filter. Once you've cleaned it, you can just reverse your step.The spark plug is located on the back side of the generator. You can simply remove the spark plug wire, and the tool is included to remove it and install it. You get a socket, and a rod. When you're done reinstalling your spark plug, you can then just reconnect your wire.And that's gonna complete our look at the etrailer 4500 watt portable generator, part number 333-0005.

Because of the climate unknowns here in California we are in a continual watch alert for high winds, fire and electrical shutdowns. As a family we are concerned about being safe and keeping our refrigerators and freezers functional in those emergent situations. Now, with our new 4500 Watt Propane/Gas generator with electric start we have one less thing to worry about. During the last electric shutdown we were without electricity for over two days. I had access to a Etrailer 333-0005. It kept our frig and freezer going just nicely. So I ordered one for ourself. It arrived via UPS in very good condition and will be unboxing it today. This generator is now one part of our household emergency backup. One less thing to worry about in those dire situations. 726729

Unbelievable. Generator came perfectly as expected. Took it out of box assembled it in 3/4 of an hour, attatched propane tank and fired it up. Works perfectly. Would definitely recommend this generator and company and would buy again from them. 700226

- 333-0005

I received my generator damaged in shipment. My daughter sent pictures to etrailer as requested. They arranged to have it picked up and returned to them, they sent a new generator out. I now have the new generator all within a few day;s, Great company to deal with. 678961

- 333-0005

Awesome little generator. We have been running it continually for the last 50 hours. It has no problem powering our 28ft Travel Trailer. So far it has only used about 7.5 gallons of fuel. It is fairly quiet. An the water proof cover with a draw string was a very nice perk! I definitely recommend etrailer duel fuel 4500! The customer service was prompt to follow up too! 728516

- 333-0005

It's a great little machine! Here's why - Delivery. I don't know what happened with the first unit I ordered, but it arrived damaged, and it appeared to be from shipping. Enough said. I contacted etrailer support on a Friday afternoon about the initial delivery, and I will tell you I had a replacement unit here on the following Tuesday! The shipper recovered the original item as well. This item is exactly what I expected it to be. It comes with a wheel kit which will take you about two minutes to install, and a front rubber shock mount base support (another two minutes to install). The unit came with a battery, and a ground connection to the battery was all that was required. I installed the quart of oil which was supplied with the unit and hooked it up to a 20lb propane tank. The unit fired up fairly quickly and I ran the generator with portable refrigerator load for about 3 hours, and then another 3 hours the next day to accommodate the 5 hour break-in period. All-in-all, it's exactly what I was looking for to compliment my RV. Connections were seamless, and the unit powered a 15,000 BTU air conditioner in my RV. The unit is heavy (100+ lbs) but easily rolls and the grip is comfortable. It's not too loud. I could hear it running inside my house though. The choke control is a little flimsy. I hope it lasts. The push button start was easy to use. The digital read-out gauge shows voltage, frequency, and hours run. Haven't tried it on gasoline but I expect equal performance. I would purchase this unit again. Comes with a two-year warranty from etrailer. I will purchase from etrailer again just for their outstanding customer support! 695250

- 333-0005

Delivered fast, after I prep it, it runs very smooth and just as quiet as the 2000 unit. Excellent customer experience as always. 667758

- 333-0005

Received it on time and in excellent shape. Followed the easy directions to set up. I had an issue with the motor reving up and down. Etrailer answered me quickly and offered a warranty replacement if the manufacturer could not resolve it. Simple issue to adjust the carburetor. It is running my van conversion perfectly. 10000 btu ac, fridge, microwave, light, tv and DVD player. Even added a phone charger. Works great. Loved the personal service. 657269

- 333-0005

It runs great and works most of the trailer all at once. I have only tried propane so far I'll try gas soon to see if it will run more at one time. So far I am very happy. K 697842

- 333-0005

Great product. Easy to assemble. I will use it when power is out. Especially after a hurricane. Will only use propane. Will use it for pressure cleaning my concrete, barns and siding. LOVE the electric start. Started first time with plenty of power. Thank you for making such a great product. 705649

I bought this generator mid March of 2020 as my wife and I decided to leave Houston area due to the corvid 19 and take our camper and park it on my parents property in a rural area. I have put 380 hours of continuous running minus the times I needed to turn off and put fuel or do an oil change. Unfortunately with our rv setup I was unable to run both acs as I have a 15k and a 13k with a residential fridge. I did try a few things to get this to work but I believe once the fridge did a cycle it would lock up the AC units. Also in the very early stage when it was new when my ac would kick in it would surge and I would have to fix it by placing my finger on the butterfly valve. After putting 18-20 hours on it this did not happen . One other small issue we did have when we hit 200+ hours was the start switch would stop working I suspect it was getting hot as it was 95-98 outside and been running non stop. The pull cord would work just fine to allow us to start it. With running one ac, some laptops, residential fridge and a mini fridge we would get 16-18 hours on a tank of gas. 794452

I live in California the Edison company shuts our power periodically during the wild fires. My generator was easy to assemble. I have propane and gas generator I used propane to start it. It started right up I plugged my refrigerator up and no problem and it even came with a nice cover. I am very satisfied with my 4500 firman generator. 786238

I was impressed with everything included to assemble and operate this generator. I ordered the high elevation carburetor jets along with the generator. I installed the jet for my elevation. After adding oil and fuel I started the generator. It fired up and run smooth. My curiosity got the best of me so I hooked up the propane tank. It started and ran great. I like the control panel. It is all strait forward and works great. I don't know about the longevity of the product but if it performs as to the attention given up to this point, I say...Great Job etrailer! 772064

Everything is excellent. I was very impressed with the video instructions and how well designed the product is. I am looking to your web site now, for everything that I buy for my RV.

  • Does etrailer 4,500-Watt Portable Generator Produce Pure Sine Wave for Sensitive Electronics
    I reached out to the manufacturer who said the etrailer 4,500-Watt Portable Generator # 333-0005 can run electronics like stereos and televisions but is not pure sine wave. I was told a better sine wave for sensitive electronics will come from an inverter generator because what an inverter does is control the voltage that is produced from the generator, making it safe for your devices. The etrailer 3,200-Watt Portable Inverter Generator - 2,900 Running Watts # 333-0002 is a great...

  • Can etrailer.com Generator # 333-0005 Be Used in Higher Elevations
    The etrailer.com generator part # 333-0005 can be used in higher elevations with the high altitude jet kit part # 333-335717005 which will allow the engine to run correctly between the elevations of 6,000 and 8,000 feet above sea level. Since you will be at an elevation of 7,000 to 8,000 feet this would work really well for you. And allows the generator to run on propane and gas at that elevation.

  • Does etrailer.com Generator # 333-0005 Have Enough Wattage for RV AC Unit
    Yes, the etrailer 4,500-Watt Portable Generator # 333-0005 will work well for you as it has 30 amp outlets on it and was designed for applications like yours. This has twice the wattage of most AC unit requirements too as it has the following outputs: Starting (surge) power output: Gas: 4,500 watts Propane: 4,050 watts Running (rated) power output: Gas: 3,600 watts Propane: 3,250 watts Based on that this would easily handle your AC system and not trip breakers like the...

  • How to Use etrailer Generator With 30 Amp Plug on RV With 50 Amp Service
    You can use your RV with 50 amp service along with the 4,500-Watt Portable RV Generator # 333-0005. The only thing that you'll need to do so is an adapter, the Mighty Cord Generator Adapter for RV Power Cord - 50 Amp Female to 30 Amp Twist Lock Male # A10-G30450VP. I have added links to video reviews of both the generator and the adapter for you to take a look at.

  • Can the etrailer.com 4,500 Watt Portable Generator be Used for a House?
    That's a great question! The 4,500-Watt Portable RV Generator - 3,600 Running Watts - Propane or Gas - Electric Start part # 333-0005 can be used to power a house during power outages. Like most generators there are limits to its capabilities of course but it will give you the power you need for your basic needs. If your home has a smaller furnace and city water, you can generally expect that 3000-5000 watts will cover your needs. If you have a larger furnace and/or a well pump, you will...

  • How Often Should Oil be Changed of etrailer 4,500-Watt Portable Generator
    That's a good question, and the engine oil of the etrailer 4,500-Watt Portable Generator # 333-0005 should be changed every 100 hours, as you can see by the cut out of the linked instruction manual I added for you. This is a propane or gasoline generator with a starting power output of 4,500 watts for gas or 4.050 watts for propane with a running watts output of 3,600 watts for gasoline or 3,250 watts for propane, which is enough to run numerous appliances at the same time - including...

  • etrailer.com 4,500-Watt Portable Generator vs Firman 3651 Generator
    You are correct that the etrailer.com 4,500-Watt Portable Generator # 333-0005 is essentially identical to the Firman 3651 in terms of function, features, design, etc but does differ with regards to the power output. It has a 4,500 watt starting output (with gas) and a 3,600 watt running output (with gas), which is just 50 watts lower than the Firman model. In reality 50 watts will make very little, if any difference in application. I even verified this with my contact at Firman. Because...

  • Changing Oil on etrailer 4,500-Watt Portable RV Generator # 333-0005
    The oil for the etrailer 4,500-Watt Portable RV Generator # 333-0005 should be replaced after the first 25 hours of running time, and after that every 100 hours of operation or annually (whichever comes first). The recommended oil type is 10W-30 automotive oil. The oil is drained by removing the drain plug and oil filler cap while the engine is warm. I have attached an image from the generator's user manual that you can also use for reference.

  • Run Time of etrailer Generator 333-0005 on Propane and What Size Propane Tanks Can be Used
    First, you are correct that the etrailer 4,500-Watt Portable Generator - 3,600 Running Watts - Propane or Gas # 333-0005 should only run on either 20 lb or 30 lb capacity propane tanks. In regards to run time on half power, we can only give an estimate but for a 20 lb tank running at half capacity it should give you in the neighborhood of 10 hours while a larger 30 lb tank should give you something in the range of 14 hours. That said, factors such as elevation can affect run times, and...

    You will be able to use the etrailer.com 4500 Watt Portable RV Generator # 333-0005 at altitudes but you will need to use the High Altitude Jet # 333-335717005. This jet kit is for use between 6000-8000ft above sea level and is the highest jet kit available.

All generators are going to make some type of noise though this is a pretty quiet one relative to its wattage.

  • How Large of Propane Tank Will Work With etrailer 4,500-Watt Portable Generator - Propane or Gas
    Though I'm not all that familiar with the phrase "propane pig" my understanding is that it is a larger residential propane tank so you would not be able to use the etrailer 4,500-Watt Portable Generator - 3,600 Running Watts - Propane or Gas # 333-0005 with something like that. As you can see from the cut out of the linked instructions, this generator is only compatible with 20 or 30 lb capacity propane cylinders and a residential tank is going to be quite a bit larger.

  • Generator Recommendation for Camper with 15,000 BTU AC Unit
    A 15k btu AC unit is going to pull up to 3,500 watts when starting up and then 1,800 watts when running. If this is all you'd basically be running then the etrailer.com generator part # 333-0005 would work well. You'd need to bypass your 1,000 watt inverter though since your AC pulls more than that. If you plan to run several accessories in your RV you'd need to step up to the etrailer 6,000-Watt Portable Inverter Generator # 333-0003-2-0007 which can support 6,000 watts starting and...

  • Can a Dual Fuel Generator be Used for a 5th Wheel Camper in Place of a Deep Cycle Battery
    You don't necessarily have to have a battery on your trailer if you are using a dual fuel generator like the etrailer # 333-0005. You just need to be sure that the draw of all of your electrical products does not exceed the output of your generator and that you have enough fuel to last your camping trip. For example, the generator mentioned above has a surge power output of 4,500 watts when using gas and 4,100 watts when using propane. The running power output is 3,600 watts gas and...

    The 7-horsepower engine in the etrailer.com 4,500-Watt Portable Generator # 333-0005 will operate for approximately 14 hours at half its rated 3600-watt load capacity on a full 5-gallon tank of gas. This works out to about 2.8 hours per gallon of gas. If the output load on the generator is more than half the rated output (more than 1800-watts) then the run time per gallon will be reduced.

  • What Is the Run Time of the etrailer 4,500-Watt Portable Generator On Propane
    The run time of the etrailer 4,500-Watt Portable Generator part # 333-0005 while on propane will be largely dependent on the amount of power being used. If you were at about 50% power consumption for example then the 10 pound propane tank which holds about 2-1/2 gallons would last around 2-3 hours. If you let me know what your power requirements are I can give a better figure to go off of.

The parallel generator kits we offer are part # 333-0001-2 with an output of 3,000 running watts, # 333-0003-2-0007 which have an output of 5,500 running watts, and # 333-0001-0002 which has an output of 4,275 running watts.
