Starting vs Running Watts: What Do the Numbers Mean?
Starting watts (surge) briefly power up motors like air conditioners, while running watts maintain continuous operation. For a 50-amp RV, you typically need at least 3,500 running watts. The WEN GN400iM provides 3,500 running watts, enough for a 15,000 BTU AC plus lights and a fridge. The Westinghouse iGen2800’s 2,200 running watts may struggle with larger AC units, but it’s fine for smaller loads.
Fuel Type and Runtime Efficiency
Most generators in this guide are gas-powered. The Pulsar PG1202SA and PowerSmart 1200W use a 50:1 oil-gas mix, while the others run on regular gasoline. Runtime varies: the Westinghouse iGen2800 runs 12 hours at half load on 0.98 gallons, which means it consumes about 0.08 gallons per hour. In contrast, the Pulsar PG1202SA uses 1.1 gallons in 5 hours (0.22 gal/hr), making it less efficient but more affordable.
Outlets and RV Compatibility
All our top picks include a TT-30R receptacle for direct RV hookup. The WEN GN5602X adds a NEMA L5-30R twist lock for transfer-switch connections, making it home-backup ready. The Westinghouse iGen2800 includes two 120V outlets and two USB ports for additional flexibility.

Frequently Asked Questions
What size generator do I need for a 50-amp RV?
A 50-amp RV typically requires at least 5,000 running watts to run all appliances simultaneously. However, if you manage loads carefully, a 3,500-watt inverter generator like the WEN GN400iM can suffice for most needs.
Can I run my RV air conditioner with a 2800-watt generator?
Yes, a 2,800-peak-watt generator like the Westinghouse iGen2800 can run a small RV AC unit if the starting surge is within its capacity. For larger units, consider a generator with at least 3,500 starting watts.
What does RV-ready mean on a generator?
RV-ready means the generator includes a TT-30R receptacle, the standard 30-amp outlet for RVs. This allows direct connection without an adapter. Some models also offer a NEMA L5-30R for transfer-switch use.
Are inverter generators better for RVs?
Inverter generators produce clean power (less than 3% THD) safe for sensitive electronics, and they are quieter and more fuel-efficient. For most RVers, an inverter is the preferred choice. For more on this, see our guide on best RV generators 30 amp.
