Running an RV air conditioner or multiple appliances on a single portable generator can quickly hit its limit. The Cummins Onan P4500i Parallel Kit lets you safely connect two P4500i generators to deliver full 50‑amp RV power from a portable setup. The result is stable, high‑output power at the campsite without stepping up to a much larger generator.
⭐ Why This Product
- Genuine Cummins Onan accessory engineered specifically for the P4500i
- Delivers true 50‑amp RV output, not just extra receptacles
