Onan P4500idf
Inverter portable generator, gasoline / lp. Ships to your door — no installation, no permit, no electrician.
4,500W Gasoline / LP Inverter — safe for electronics Dual fuel $100.00 shipping
Inverter generators produce clean power - low total harmonic distortion - which means you can run laptops, routers, modern TVs and variable-speed equipment off it without worrying about what the waveform is doing to them. They are also dramatically quieter than a conventional open-frame set, and they throttle down when the load is light instead of running flat out.
Running gasoline / lp is the practical advantage here. Gasoline degrades in months and is the reason most stored generators will not start. Propane does not degrade at all, so a unit kept on LP is far more likely to fire on the first pull after sitting through a mild year.
Ship weight is 125 lb. Portables cover essentials during an outage: refrigeration, lights, well and sump pumps, phones and networking. They do not run central air conditioning, which in a Texas summer is usually the load that actually matters — if that is your concern, a permanently installed standby unit is the honest answer.

The P4500idf is sold by UTS ElectricPros, an authorized Cummins dealer in Dallas–Fort Worth. Buying through an authorized dealer is what keeps the manufacturer warranty valid — equipment bought from an unauthorized reseller frequently is not covered, and owners tend to find that out at the worst possible moment.

Questions about the P4500idf
How much is the Cummins Onan P4500idf?
$1,146.15, plus $100.00 shipping. There is no installation, no permit and no electrician involved with a portable, so $1,246.15 is the whole cost.
What will the P4500idf run?
It is rated at roughly 4,500 starting watts. In practical terms that covers a refrigerator, several lights and outlets, a sump or well pump, and either a small window AC or a space heater - not both. A portable will not run central air conditioning; that is what a standby unit is for.
Can the P4500idf run on propane?
Yes. This is a dual-fuel unit running on gasoline / lp. Propane is the practical choice for a generator that sits most of the year: it does not go stale, it does not gum a carburetor, and a 20 lb tank is easy to store and rotate. Gasoline gives slightly higher output when you need it.
Can I use the P4500idf to back-feed my house?
Only through a properly installed transfer switch or an interlock kit. Plugging a generator into a wall outlet - a suicide cord - back-feeds the utility line and can kill a lineman working to restore your power. It is also illegal. If you want the generator to power house circuits, we install a manual transfer switch, and if you are doing that anyway it is worth asking whether a standby unit is the better buy.

What it is for
Power you can carry to where it is needed
You need electricity somewhere there is none, or somewhere it has just stopped. Camping and tailgating, a jobsite before the service is energised, running tools at a property with no supply, or covering the refrigerator, the lights and a pump through a short outage at home.
Why it becomes urgent
No installation, no permit and no electrician — you buy it, it ships, and it works the day it arrives.
Who buys it
Campers, tailgaters, tradespeople, and homeowners who want a fallback without a five-figure installation.
Before you buy the P4500idf
The questions that decide whether this is the right machine, answered properly rather than in a sentence on a product page.
- Natural gas or propane?Fuel decides runtime, refueling and what the gas side of the install costs.
- What fuel should I be running?Gasoline, propane and diesel each change runtime and storage.
- Would a permanent standby suit me better?A portable is manual and refueled by hand. Standby starts itself.
