Recommended size: 3,500–5,000W
A 3,500–5,000W generator is the right size for RV camping with air conditioning. An RV air conditioner draws 3,000W starting and 1,800W running, leaving enough headroom on a 3,500W+ unit for your RV fridge, TV, lights, and phone chargers. Look for an inverter model or one with a TT-30R RV outlet.
Best value in the portable inverter class. CO Shield safety shutoff, parallel-ready, and RV-ready with a TT-30R outlet.
RV generators face a unique challenge: the air conditioner dominates the power budget at 3,000W starting surge, but everything else in the RV draws relatively little. A 3,500W inverter generator handles the AC startup plus 500–700W of other loads. If you want more headroom for a microwave or hair dryer, step up to 5,000W. The Champion 3500W Inverter listed below includes a TT-30R outlet specifically designed for RV hookup. Inverter generators are strongly preferred for RVs because they produce cleaner power (lower THD) that protects sensitive electronics and run significantly quieter than conventional models.
