High-Output Capacity

outlets

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 RV outlet, ensuring you'll have access to electricity no matter where you take your RV or if there's a power outage at the campground. The generator also has outlet covers to help keep out moisture and debris.


Easy Electric Start Engine

The generator's engine starts up easily at the push of a button. 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. Once you press the start button, the generator will turn on.


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. Once the generator is up and running, follow the recommended order of operation: connect the device with the highest starting watts first, like your air conditioner or refrigerator, then work your way down to the device with the lowest starting watts. By connecting devices in this order, you'll ensure the generator has enough power to start high-wattage loads.


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 fuel is a cleaner option for the environment. However, the power output slightly decreases while using propane.


  • 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

It also includes a 5' LPG hose to connect your propane tank. Once you have connected your generator, turn the fuel selector switch to the LPG position and start it up.


Safety Features

This generator comes with a number of safety features to protect you, the environment, and the generator itself. 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. The digital voltage regulator assists in minimizing voltage fluctuations which helps to maintain a steady flow of electricity. Also, a built-in spark arrestor helps prevent any sparking that might burn someone or start a fire. This arrestor has been certified by the USDA Forest Service.


Choosing a Generator

When choosing a generator, you need to match the generator's starting and running output with the electrical demands of the equipment 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 that 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 e3200 inverter 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

The following section provides calculations for wattage estimates. This will give you an overall picture of your potential power usage and help you decide on the generator that is right for you.


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
Refrigerator1,600800
Microwave01,000
Blender850400

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
Refrigerator1,600800
Microwave01,000
Blender850400

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.

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

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

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

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

This generator works great for keeping the refrigerator, lights, small heaters or fans and any other small needs (i.e. charging electronic stuff.) The only reason its a 4 star is its a little hard to start if its sat for a while. Takes some patience and trimming the choke but it always started and was easier once its going and there isn't a lot of time between uses. 903473

the generator has been working perfectly each time we've had an outage. there have been three here in the last year. Since my wife is on an oxygen machine 24 hours a day, it only takes a few minutes to start the machine and pull drop cords into place. One of the best purchases I have made in my 77 years. 900107

by:

The model work really well and is compact and not too loud. I've tried it with both gas and propane and got better (more stable) results with gas. With propane, after a couple of hours the generator started making a cyclical winning sound (still we did not experience an appreciable change in the current or performance of our appliances connected to it.) 898905

The generator outperformed my expectations. It has fit perfectly into our “on again, off again” safety power shut offs in Northern California. I would offer just one important suggestion. I need a LONGER OIL DRIP STICK as it is very difficult to check the oil and get the drip stick out and in. 894317

We currently own the 4,500-Watt Portable RV Generator - 3,600 Running Watts - Propane or Gas - Electric Start (Item # 333-0005) for our travel trailer. With Hurricane Laura passing through Louisiana it really put this generator to this test. It passed with flying colors both running my travel trailer and one appliance in the house, To take a lot of the load off of this one, I ordered this model, 4,500-Watt Portable Generator - 3,600 Running Watts - Gas - Remote Start Item #333-0004. We received the item yesterday afternoon via UPS. Assembly was great and instructions were easy to understand. Fueled and oiled it up, and tried all three options (remote, push start, pull cord) to start it with little or no hesitation. The easy choke is a nice feature, by pushing it to start and it automatically adjust. There is another nice feature having an onboard bottle opener on the back. I would recommend Item # 333-0008, Storage Cover for etrailer 4,500-Watt Generator - Weather Resistant. 891910

Great product. Still too new to give a five star and it will only be used as backup power for my house. One glitch I already discovered is the fuel selector switch is very sloppy so you need to ensure it is EXACTLY in the right position. I'm using propane so after killing the battery trying to start it and sweating bullets pulling the starter cord I fiddled with the switch. Eventually I hit the right spot and it started. 849703

It’s 4500 generator is amazing. I did The break in on it just recommended. It was 90 plus degrees when i did the break in. Then after 5 hours came the big test running 13,500 ac unit. It was at 62 to 63 before I pugged In the rv and turned on ac and went out side to check again and it dropped to 61.5. Ran the 16 bunk house for 20 minutes and the rv dropped from 90 plus degrees to 75 degrees. There was a little jump In noise from 4500 from turning on the ac but after that ran like a champ. This 4500 duel fuel generator is amazing. 817199

  • 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...

  • 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.

  • Will the 4,500-Watt Portable RV Generator Fit Inside the Stromberg Carlson Trailer Tray
    The dimensions of the 4,500-Watt Portable RV Generator part # 333-0005 are 25-3/4" long x 21-3/4" wide x 21-5/8" tall which includes the wheels. I don't have any dimensions without the wheels but they look around 1" thick so the base is likely around 19"-20" wide without them. Therefore, it should fit inside the Stromberg Carlson Trailer Tray Cargo Carrier part # CC-255 but it would be very tight.

  • 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...

  • 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...

  • Troubleshooting etrailer 4,500-Watt Portable Generator Not Starting
    I reached out to the manufacturer and he gave me some tips on troubleshooting for your etrailer 4,500-Watt Portable Generator # 333-0005: 1 - It would be best to get the battery charged at an auto parts store (you can also do this using a charger like part # CTEK56353) 2 - Sometimes when running the propane you need to adjust the choke while starting 3 - You can have them clean the spark plug 4 - Disconnect the regulator from propane tank, reconnect turning the propane valve on slowly 5...

  • What is Difference Between Firman and etrailer.com Brand Generators
    The etrailer.com and Firman brand generators are essentially the exact same thing just branded differently. The advantage to the etrailer brand is the price is going to be a bit lower. The advantage to the Firman brand is a life time warranty on parts when used in non-commercial applications.

  • What is the Decibel Level of etrailer 4,500-Watt Portable Generator
    The etrailer 4,500-Watt Portable Generator # 333-0005 has been measured at 67 decibels 25 feet away at 1/4 load, which is just a bit louder than the amount of noise made during a conversation. All generators are going to make some type of noise though this is a pretty quiet one relative to its wattage. I have added links to a couple video reviews of this generator for you to take a look at.

  • 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...

  • Which etrailer.com Generators Can be Used with Parallel Kits and Why
    We have generators that can be used with parallel kits to roughly double the amperage rating but the only styles that can do this are the inverter style generators which produce cleaner power. The # 333-0005 does not have an inverter so it can't be ran in parallel. 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.

  • What Are the Break In Procedures for the etrailer 4500-Watt Generator
    We consider the first 5 hours of run time on the etrailer 4500-Watt # 333-0005 to be the break-in period for the unit. During the break in period stay at or below 50 percent of the running watt rating and vary the load occasionally to allow stator windings to heat and cool. Adjusting the load will also cause engine speed to vary and help seat piston rings The only thing we do recommend is that the first oil change should happen after 25 hours of use, but after that you will only need...

  • Will etrailer Generator Run if it is Low on Oil
    That's a good question; the 4,500-Watt Portable RV Generator # 333-0005 would not be able to run if the oil drops below a preset level, as indicated in the cut out of the linked installation instructions. There is an oil switch which will actually stop the engine on the generator from running until the oil level is corrected. If this happens then yes, a service technician would have to be called. That said, adding oil to this generator is extremely easy, no matter what your mechanical...

  • 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...

    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.

  • 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.

    The etrailer.com 4,500-Watt Portable Generator # 333-0005 that you referenced does have dual-fuel capability and an electric-start engine that allows for simple push button startup, however it does not have a remote start option. We do not currently have a dual-fuel generator available that has a remote start option. The etrailer.com # 333-0005 is a really nice generator with a 4,500 watt starting power output (4,100 watts with propane) and a 3,600 watt running output (3,300 watts with...

  • Will the etrailer Portable Generator Run on Natural Gas
    The etrailer 4,500-Watt Portable Generator part # 333-0005 cannot run on natural gas nor am I aware of an adapter that would allow you to do so. This will be the case for all of the etrailer Portable Generators. The 4,500 watt generator must be used with either gas or propane.

  • 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.
