Cummins Onan 4500 Watt Generator Add-ons

What add-ons fit the Cummins Onan P4500i inverter generator?

This collection covers accessories built specifically for the Cummins Onan P4500i portable inverter generator, including exhaust extensions, parallel kits, and covers. Confirm your generator model number stamped on the unit before ordering to make sure the add-on matches your serial range.

Do you carry an exhaust extension for the Onan 4500i RV generator?

Yes. The exhaust extension routes hot exhaust gases away from your RV or campsite, which is useful when running the P4500i close to the rig during extended use. Pair it with a surge protector or transfer setup from our RV electronics collection to protect downstream loads.

Can I plug the P4500i into my RV shore power inlet?

The P4500i has a 30-amp TT-30R outlet that connects directly to a standard 30-amp RV shore cord. If your rig runs on 50-amp service or you need to step down for a 15-amp household tail, see our RV plug adapters for the correct dogbone configuration.

How does shipping work on Onan 4500 generator accessories?

Most add-ons in this collection ship via standard ground freight. Orders over $100 ship free within the contiguous US. If you need help confirming fitment before you order, text or call our team at 817-984-1852.
