It means that if the total load on your generator is less than 1650 watts, your generator will run for approximately 12.3 hours with one full tank. The run time will decrease or increase when you alter the load on the generator. With a full load, the time will be around 5-6 hours with a full tank of gas.

Dimensions and Weight: The generator weighs 90 pounds and has a dimension of 17.5 x 18 x 18 inches. Considering the weight, it won’t be easy to move the generator without a set of wheels. For RVs, it is best to be kept at the designated space of the generator.

2. Champion Power Equipment 100307 4375/3500-Watt Dual Fuel RV Ready Portable Generator – Best Dual Fuel Generator below $500

Champion RV power station

Fuel Type and Tank Size: Champion is one of the best companies producing dual fuel generators. Such generators offer your versatility and freedom while running them. It can run on propane and gasoline. While gasoline has a short shelf life and may not be available during natural disasters, propane has a shelf life of 30 years. The generator has a gas tank capacity of 3.4 gallons of gas.

Power Capacity: Dual fuel generators differ in capacity with respect to the fuel being used in them. Gas burns better and provides more power to the engine; therefore, the generator produces more power than propane. This model has a starting wattage of 4375 and a running wattage of 3500 on gasoline. On propane, it offers 3950 peak wattage and 3150 running wattage. Here lies the catch, if you are planning to buy a dual fuel portable generator to be mostly run on propane, always calculate your appliance wattage keeping in mind the wattage figures for propane. If you are going to use propane occasionally and during the crisis hour, you would have to skip some appliances. For example, you can skip the TV and a couple of lights. They would cover up the difference of 350 running watts in propane and gas.

Buying Guide

When you are buying something like a generator, it is very important to make sure that everything you need is featured in it. We have developed this buying guide according to this concept. Our buying guide will discuss all the factors that may impact your purchase decision. It will enable you to get the most out of your money.

Power Needs

The most important and critical consideration to make is to calculate your power needs. It is a simple process and does not need any rocket science or complex formulas to do it. We will teach you how to do this. First of all, make a list of all the appliances you plan to run on the generator. Mention the starting wattage and running wattage for every appliance in the list. The total of the starting wattage is the maximum power you will need if you add all the appliances at once on your generator. The total of the running wattage will be the power your generator needs to provide to keep all your appliances running once they are started. Consider the following table for a better understanding.

Appliances Starting Wattage Running Wattage
Refrigerator 1200 200
1/2 HP Furnace 2350 875
TV 300 300
Lights 300 300
AC 1800 1200
Total 5950 2875

If you go by the table, you would need 5950 watts to power all these appliances. However, to keep them all running, you need only 2875 watts. If you are new in this field, you will go for a large generator. Actually, you need a 3000 watts generator to run all the appliances at one time. You just need to do a bit of load management and add heavy loads one by one. It would be best to take off the loads once you are done using them to enhance fuel efficiency and keep your generator running light.

Similarly, you can use this formula to calculate wattage for RV or personal use generators. Make sure you add a cushion of 200-300 watts above the running wattage to accommodate any other appliance.

Inverter or Classical Generator

A classical generator has more power output than an inverter. It can power up a lot of appliances in your home, has a large fuel tank, and is more rugged and can withstand more running time than inverters. Classical generators are louder as compared to inverters, heavier and difficult to move around.

Inverters are lightweight, produce clean electricity, which is safe for your sensitive devices like phones, laptops, and chargers. The maximum power an inverter can give you is around 7000 watts. Inverters under $500 can give a maximum power of 2200 watts. Inverter generators can be connected in parallel to increase the power output.

The choice here is yours; if you plan to run your home appliances, a classical generator is best as it can accommodate more things. For outdoor purposes, an inverter is best as it is lightweight, easy to carry and store.

Type of Fuel

Here you have the choice of going for gas-powered, propane, or dual fuel generators. Dual fuel generators have the added advantage of being run on gas and propane. You can store propane and use it when gasoline is not available. Propane won’t go bad as it has a shelf life of 30 years. Gas, on the other hand, burns better and produces more power from your generator.

Starting Mechanism

Don’t go for a recoil generator if you don’t feel comfortable pulling the starting rope. An electric start generator gives you the ease of operation. However, maintaining a recoil generator is easy as compared to an electric one. The repairs are also less costly.

Control Panel

A user-friendly generator will offer you maximum information and control on the control panel. A fully operational and practical control panel will have buttons, light indicators, outlets, fuel selector switches, and other options. A few latest models also tell about the oil level, fuel level, and load applied. However, as the features increase, the price tag also goes high.

Noise Level

One thing you should look out for is the noise your generator is going to produce. If you plan to use your generator for camping purposes, make sure you get one with the lowest noise output. Inverters are best for this purpose. Inverters have as low as a 50-decibel noise rating. On the other hand, conventional generators are noisier than the inverters and have sound levels up to 70 DB.  You can install mufflers and move the exhaust upwards to quiet them up a bit, but they will still make a lot of sounds.


Check for the grounding of your generator before you start it. You can read all about it in the user manual. Make sure you buy a generator that is safe to use and has features like low oil shutdown, overheating shutdown, voltage surge controller, and an overloading sensor. All these features not only avoid mishaps with the generator but also keep people in proximity safe.

Warranty & Certifications

Warranty and certifications increase the value of your money and give you peace of mind. If you live in California, don’t buy a generator without a CARB certification.


You must always look for a durable generator. By durability, we mean the components used inside them. Luckily for you, all the generators in our list are highly durable and will stay with you for at least 15-20 years.
