Where to buy Cummins Onan Portable Generators

Now available on


Portable vs. standby - which generator is right for you?

Generator sales "spike around major storms - just before and a few weeks after - which means that too many buyers shop when the power's out."*

Cummins standby home generators are No. 1 for a reason - they deliver ultimate reliability, ensuring peace of mind before the power goes out. Don't wait until the power is out to buy a generator.


Find the right Cummins Generator


Financing through Synchrony

Rely on a brand that is synonymous with power. Cummins is now offering financing options through Synchrony Bank when your portable generator or home standby unit purchase is made with a credit card issued through Synchrony. Financing is only offered through participating dealers. Contact your local dealership to see if they offer financing.
