How to Use a Generator to Charge an RV Battery
Simply hook the RV power wire into the generator like a shore power post at a campground to charge an RV batteries with a generator.
A regular 30 amp/120-volt receptacle should be incorporated into your generator.
If the voltage is 220 volts, you’ll need an adaptor.
That’s a high-level summary of how to use a generator to charge an RV battery.
Let’s take it step by step and go over some crucial safety measures while utilizing a generator.
As an example, consider the Honda EU3000IS 3000W 120V Inverter Generator.

Before we connect in our RV’s power cable and start the generator, we need go through a few safety considerations.
Important Safety Requirements
- Use your generator only outdoors, at least 3 feet away from any open windows, vents, or doors.
- In the event of an emergency, know how to swiftly shut off your generator.
- Read the owner’s handbook thoroughly to ensure that you understand all of the controls and receptacles, as well as all of the safety concerns applicable to your model.
- If you’re using a portable generator, be sure it’s on level ground.
- Examine any cables you want to connect to the generator. If it’s broken, replace it.
We’re ready to start charging your RV batteries after you’ve done all necessary safety steps.
Step-by-Step Charging of RV Batteries
Important: Check the oil and fuel levels, as well as the air filter, before trying to start your generator.
- Start your generator: Although each generator model is somewhat different, when charging RV batteries with a Honda generator, such as the one we’ll be utilizing in this example, turn off the eco throttle switch first. Then start the generator by turning on the fuel valve, closing the choke, and turning the key to the “On” position. Finally, re-insert the choke knob.
- Allow generator to warm up: Allow your generator to operate for a few minutes after starting it before attaching any electricity wires or appliances to it.
- Plugin the RV power cord: Like a shore power post, connect the RV power chord into the generator’s built-in 30 amp/120-volt AC socket. You may require a 30 amp twist to 30 amp RV converter if your RV’s power cable does not fit into the generator’s 30 amp receptacle.

That concludes our discussion.
Your generator should now be recharging your RV batteries and powering any electrical gadgets that it can handle in your vehicle.
How Long Should a Generator Run to Charge RV Batteries?
The capacity of your batteries, the power of your generator, the number of appliances you’re running, and the number of batteries you’re charging all have a role in how long it takes to completely charge your RV battery.
It might take up to 8 – 10 hours to completely charge your RV or camper batteries if it has been down to 20 – 30 percent power.
If your battery is almost full, charging it to full capacity may just take a few hours.
Is it possible to charge a deep-cycle battery using a generator?
When you use a generator to charge your RV’s battery, you’re probably charging a 12v lead-acid deep cycle battery, which is typical in recreational vehicles and travel trailers (though lithium batteries are becoming more popular).
So, sure, you can use your generator to securely charge a deep cycle 12-volt battery.
Why isn’t my RV battery being charged by my generator?
There might be various reasons why your generator isn’t charging your RV battery:
1. Make sure the battery is not disconnected by checking the battery disconnect.
2. Make that the converter circuit breaker is turned on and the fuses are in excellent working order.
3. Make sure the generator’s primary breakers aren’t tripped.
4. Examine the battery’s water level and general condition.
If you’re not sure how to diagnose your RV’s electrical system, get assistance from a licensed RV technician.
Is an RV Generator Capable of Charging House Batteries?
Yes, your RV generator will charge your home batteries and power any 120-volt appliances when plugged in and operating.
What is the quickest method of charging RV batteries?
Connecting to shore power and utilizing a high amperage multi-stage battery charger is perhaps the best and quickest method to charge RV batteries.
