Yes, you can charge many portable power stations with a small gas inverter generator, and it can be a smart backup strategy during outages, camping trips, RV travel, and cloudy weather.
Solar charging is useful, but it can be slow when sunlight is weak. A small quiet inverter generator can recharge your power station much faster, letting you run the generator for a short time and then use silent battery power afterward.

What Is Hybrid Backup Power?
Hybrid backup power means using more than one power source together.
In this setup, you use:
- A portable power station for quiet battery power
- Solar panels when sunlight is available
- A small inverter generator when faster charging is needed
The basic idea is simple:
- Run the gas generator outdoors
- Plug your power station charger into the generator
- Recharge the power station quickly
- Shut the generator off
- Use the power station silently indoors or at night
Why Use a Gas Generator to Charge a Solar Generator?
The biggest reason is speed.
Solar charging depends on sunlight, panel size, weather, and panel angle. During storms, cloudy days, winter conditions, or shaded campsites, solar charging may not keep up.
A small inverter generator can provide steady AC power so your solar generator or portable power station can recharge much faster.
This can be useful for:
- Power outages
- Hurricanes and storms
- Camping trips
- RV use
- Off-grid cabins
- Emergency preparedness
Why an Inverter Generator Is Better Than a Regular Generator
If you are charging a portable power station, a small inverter generator is usually the better choice.
Inverter generators are popular because they are generally:
- Quieter
- More fuel efficient
- Better for sensitive electronics
- More portable
- Cleaner output than many conventional generators
For this use case, the generator is not meant to run your entire house directly. It is mainly used as a fast battery charger for your power station.
Best Small Generators for Charging Portable Power Stations
Here are a few small inverter generators that make sense for charging portable power stations outdoors.

How to Charge a Power Station With a Gas Generator
The process is usually simple, but always follow the instructions for both your generator and power station.
- Place the generator outdoors in a well-ventilated area.
- Start the generator and let it stabilize.
- Plug the power station’s AC charger into the generator.
- Monitor the input wattage on the power station display.
- Recharge to the level you need.
- Shut the generator off and use the battery station quietly afterward.
Important Safety Warning
Never run a gas generator indoors, in a garage, basement, shed, enclosed porch, or near open windows.
Gas generators produce carbon monoxide, which can be deadly. Always operate generators outdoors, far away from doors, windows, vents, and living spaces.
Also use properly rated outdoor extension cords and follow all manufacturer instructions.
Why This Setup Can Save Fuel
Instead of running a gas generator all day or all night, you can run it only long enough to recharge the power station.
Then you shut the generator off and use the power station for:
- Phones
- Lights
- WiFi router
- CPAP machine
- Small fridge
- TV or laptop
This can reduce noise, fuel use, and generator runtime.
When This Strategy Makes the Most Sense
Charging a solar generator with a gas generator makes the most sense when:
- Solar charging is too slow
- The weather is cloudy
- You need backup power for multiple days
- You want quiet power at night
- You want to conserve fuel
- You already own a portable power station
When It Does Not Make Sense
This setup may not be worth it if:
- You only need short-term phone charging
- You already have enough solar panels
- You do not have safe outdoor generator space
- You need full whole-home backup power
- Your power station charges very slowly from AC
Best Power Stations for Hybrid Charging
This strategy works best with portable power stations that support fast AC charging.
Look for models with:
- Fast AC input
- LiFePO4 battery chemistry
- Clear input wattage display
- Enough capacity for overnight use
- Expandable battery support if needed

Final Verdict
Using a small gas inverter generator to recharge a solar generator can be a very practical hybrid backup power strategy.
Solar panels are great when sunlight is available, but a small inverter generator gives you a faster recharge option when weather, shade, or outage conditions make solar charging unreliable.
The best approach is often:
- Use solar when conditions are good
- Use a small generator for fast emergency recharging
- Run silently from battery power when possible
This gives you more flexibility than relying on solar or gas alone.
