Power Output: Matching Watts to Your RV Battery Charger
The most critical spec for charging RV batteries is the generator’s running (rated) wattage. A typical RV battery charger draws between 300 and 800 watts, depending on the battery bank size and charger type. For example, the PowerSmart 3800 provides 3300 running watts on gas, which can easily run a 50-amp charger while also powering a small refrigerator or lights. In contrast, the Pulsar PG1202SA’s 900 running watts is sufficient for a dedicated battery charger but leaves little headroom for other loads. As a rule of thumb, choose a generator with at least 1500 running watts if you plan to charge batteries and run a few small appliances simultaneously.
Inverter vs. Conventional: Why Clean Power Matters for Batteries
All five generators in this roundup are inverter models, which produce pure sine wave power with less than 3% total harmonic distortion (THD). This clean power is essential for modern RV battery chargers, which use sensitive electronics to manage charging profiles. A conventional generator with higher THD can damage the charger’s circuitry or reduce battery life. The Westinghouse iGen2800 and Pulsar G2319N both advertise less than 3% THD, making them safe choices for lithium-ion and AGM battery systems.
Fuel Type and Runtime: Gas vs. Propane vs. Dual Fuel
Dual-fuel generators like the PowerSmart 3800 offer the flexibility to run on either gasoline or propane. Propane has a longer shelf life and burns cleaner, which is ideal for emergency backup, while gasoline is more widely available at campgrounds. The PowerSmart 3800 delivers 3100 running watts on propane, only slightly less than on gas. For single-fuel models, the Westinghouse iGen2800 offers up to 12 hours of runtime on a 0.98-gallon tank at quarter load, while the Pulsar G2319N runs 4.8 hours at half load on 1.18 gallons. If you plan to charge batteries overnight, look for a generator with at least 8 hours of runtime at a 50% load.
Portability and Noise: Campground Considerations
Noise levels matter in campgrounds and RV parks. The Westinghouse iGen2800 operates at just 52 dBA, which is quieter than a normal conversation, while the PowerSmart 3800 is rated at 70 dB at 23 feet. Weight also varies: the PowerSmart 3800 is the heaviest at 50.7 lbs, while the PowerSmart 1200W weighs only 39 lbs. For frequent moves, a lighter inverter generator with a handle or wheels is easier to manage. The Pulsar PG1202SA’s suitcase design with a handle is a good compromise between portability and power.
Safety Features: CO Sensors and Outlet Protection
Safety should never be overlooked. The PowerSmart 3800 includes a built-in carbon monoxide (CO) shutdown sensor that automatically turns off the generator if dangerous CO levels are detected. This is a valuable feature for RV use, where generators are often placed near living spaces. All models in this roundup have standard outlet protection and comply with EPA emissions standards.

Frequently Asked Questions
Can I use a generator to charge my RV batteries while driving?
Yes, but only if the generator is securely stored and properly ventilated. Never run a generator inside a moving vehicle or in an enclosed space. Most RV owners use a generator while parked, connecting it to the RV’s shore power inlet or directly to the battery charger.
What size generator do I need to charge two RV batteries?
For a standard dual-battery setup (around 200 amp-hours total), a generator with at least 1000 running watts is sufficient for a dedicated battery charger. If you also want to run lights, a refrigerator, or other appliances, consider a 2000-watt or larger inverter generator. Our RV AC guide has more details on matching power to your needs.
Is inverter power necessary for charging RV batteries?
Yes, inverter generators produce clean sine wave power with low total harmonic distortion, which is essential for modern battery chargers. Using a conventional generator with high THD can damage the charger’s electronics or reduce battery lifespan. All models in this roundup are inverter generators.
How long will a generator run while charging RV batteries?
Runtime depends on the generator’s fuel tank size and the load. For example, the Westinghouse iGen2800 can run up to 12 hours at quarter load on 0.98 gallons of gas. At half load, the Pulsar G2319N runs 4.8 hours on 1.18 gallons. If you’re only charging batteries, the generator will run longer because the load is lower.
