It supports dual fuel, with a long-running runtime on a six-gallon tank and a comprehensive outlet configuration, including RV and household outlets. Best for: larger homes or campers needing ample, switch-ready power. Caution: high output requires careful load management to avoid overloading transfer switches.
PowerSmart 3600-Watt Portable Inverter

This compact inverter generator delivers 3600 starting watts and 3200 running watts with inverter technology to provide clean power ideal for sensitive electronics. It is RV-ready and supports a 30A outlet, making it a solid choice for campers and light-home use. Best for: users prioritizing clean power and quiet operation in portable form. Limitation: lower overall wattage compared with larger units.
Buying Guide: Key Considerations for 220V Outlets
- Voltage and outlets: Look for 120V/240V dual-voltage capability to support 220V-ready loads or transfer switches. Check the receptacle types (L14-30, 14-50, etc.).
- Fuel type and economy: Dual-fuel models offer flexibility (gasoline or propane). Consider fuel availability and run-time for outage scenarios.
- Electric start vs pull-start: Electric start improves convenience during outages but may add a battery requirement and slight weight increase.
- Power output: Determine required surge watts and running watts. For 220V operation, ensure the unit can handle your heaviest appliances and transfer-switch needs.
- Safety features: CO detectors, low-oil shutdown, and anti-overload protections are important for safety and equipment longevity.
- Runtime and maintenance: Larger tanks deliver longer runtimes. Note maintenance intervals and oil requirements in the user manual.
- Portability vs. capacity: Open-frame vs. portable designs balance size, noise, and mobility. Wheels and handles help with transport.
- Noise level: Inverter generators typically offer quieter operation—consider neighborhood sensitivity and usage time.
- Warranty and support: Check warranty terms and availability of service centers in your region.
Frequently Asked Questions
- Do these generators support 220V loads directly?
- Is dual-fuel better for emergencies?
- What is “THD” and why does it matter?
- How important is a CO safety feature?
- What size transfer switch is needed for whole-house backup?
- Can I use these indoors or in an enclosed space?
Many listed models provide 120V/240V dual-voltage capability, which allows 220V-like operation when connected to appropriate transfer equipment or loads designed for 240V. Verify receptacles and transfer switch compatibility before use.
Yes. Dual-fuel models let you choose between gasoline for maximum power and propane for longer run times or fuel availability during outages.
THD stands for Total Harmonic Distortion. In inverter generators, a low THD (<3%) means cleaner sine waves suitable for sensitive electronics and chargers.
CO safety helps detect dangerous carbon monoxide levels and can shut down the generator to prevent harm in enclosed spaces.
Transfer switches vary by home and panel; common options include 30A, 50A, or 60A configurations. Ensure compatibility with your generator’s output and your main panel.
No. Generators produce dangerous exhaust, including carbon monoxide. Always use outdoors with proper ventilation and distance from living spaces.
