How to Choose Between Lithium Battery and Fuel Powered Generators

This list has a combination of lithium battery power stations and fuel-powered power stations. Each has its pros and cons, which are listed in detail below. Each type of generator boils down to preference and needs. 

If you don’t need that much power, you can get the lighter, more portable lithium battery generators. If you need more energy for more extended periods of time, you will sacrifice noise level and portability with the bigger fuel-powered generators.

Lithium Battery Powered Generators

These generators must be charged at intervals and don’t put out as much power as fuel-powered generators. Below are the pros and cons of battery-powered lithium generators:


  • Lightweight
  • Very portable
  • Green energy with solar panels
  • Multiple ways to charge the battery


  • Limited power time
  • Lower wattage output
  • It takes time to recharge batteries

Fuel Powered Generators

Generators who use gasoline or propane to power engines will be more powerful and last for as long as you have fuel. However, when you use fuel-powered generators with engines, you have to always deal with buying the fuel and listening to the running engine. 

These generators usually have much more power and power outlets than battery-powered generators. Below are the pros and cons of fuel-powered generators:


  • Powerful wattage
  • Long-lasting power
  • Many power outlets


  • Heavy
  • Hard to transport
  • Fuel costs money
  • Very loud engine

What Type of Fuel do Generators Use? 

There are three types of fuel that generators that are used for recreational RV camping use. The most common fuel types for generators are gasoline, propane, or in some cases diesel. The pros and cons of each fuel type are listed below: 


  • Pros: 
    • Available everywhere
    • Burns cleaner than diesel; fewer fumes
  • Cons: 
    • Less efficient than other types of fuel
    • More expensive than other types of fuel


  • Pros: 
    • Cleanest burning fuel
    • Costs less
    • Safer than other alternatives
  • Cons:

  • Pros:
    • Fuel efficient
    • Cost-effective
    • Diesel is available everywhere

    • Harder to repair than other generators

What Size Generator do RVs Need? 

Some guides may tell you that there are different generator wattages that are needed for 30 AMP or 50 AMP RVs. However, the best way to go about getting the right size generator for your RV is to look at the overall power you need and then add about twenty percent extra for total coverage if you are running everything at full power. 

For example, “a 50-amp RV requires a 12,000-watt generator to power everything at 240 volts and a 6,000-watt generator at 120 volts.” (Source: Electric Generators Direct) So, it really depends on the power that you will be running your appliances at. 

Some other points to keep in mind are: 

  • Physical size: Make sure there is enough storage space to fit your generator into the space in your RV. If it won’t fit, then you will need additional towing which could be a huge hassle and not worth it. 
  • Power Needs: Use a chart like the one below and add up all the starting wattages of the appliances in your RV to determine the power needs of your generator.
Appliance Type Starting WattsRunning Watts
Air Conditioner1400-20001700
Electric Stove530-1500675
Electric Water Heater1000-15001250
Coffee Pot(4 cups)550-750650
Portable Heater1500-7501500

When do you Use an RV Generator? 

Most RV campgrounds will have 30 or 50 amp electrical hookups where you can use the electrical power from the campsite to run all of the appliances in your RV. However, if you are off the grid, or at a campground that does not offer the power that you need for your RV and its appliances, you may need to get a generator.

Can you Run a Generator While Driving or Towing your RV? 

It is perfectly fine to run your generator while you are driving or towing it. Since you may want to keep things like the refrigerator running twenty-four hours a day, running the generator will help you accomplish this. 

There are several safety concerns to consider before deciding if you should run your generator while you are driving or towing it. Most Motorhomes will need to run a generator as you drive to run AC and other essentials, but if it is not essential to your trip consider these safety concerns. The precautions for your safety while using a generator if you are driving or towing an RV are listed below: 

  • Make sure there is ventilation for the fumes of the generator to escape
  • Fill up the tank of fuel on your generator before a long ride
  • Secure the generator in a place where fuel will not slosh around and spill
  • Secure in a place where the generator will not slide while accelerating or braking
