How much power does the Westinghouse WGen14500TFc give you?
On gas, this model is rated for 14,500 running watts and 18,000 starting watts. Running watts are the power available while your appliances are on. Starting watts are a short burst to help things like refrigerators and pumps turn on. You cannot use that bigger number for appliances that need steady power.
On natural gas, the running rating drops to 11,600 watts. Use that number when adding up your appliances if natural gas is the fuel you plan to use.
| Fuel | Running watts | Starting watts |
|---|---|---|
| Gasoline | 14,500 W | 18,000 W |
| Propane | 13,000 W | 16,000 W |
| Natural gas | 11,600 W | 14,400 W |

A 120V outlet powers ordinary household plug-in devices. Some pumps and larger equipment need 240V. Inverter models use electronics to control the electricity they supply. THD measures how smooth that electricity is; a lower number generally means smoother power. Check your device instructions before connecting electronics.

How long will it run?
The published runtime is Up to 16hrs at 25% gasoline power use; Up to 9hrs at 50% gasoline power use. The listed gas tank holds 10.5 gal (40 L). The more power you use, the sooner you will need fuel. A runtime measured at 25% load means the generator was only supplying a quarter of its running power, not working flat out.
A natural-gas connection can save repeated trips to fill the gas tank, but gas service can fail too. Have a qualified installer check that the supply can feed the generator while your other gas appliances are running. Read our fuel-storage guide →
What can you run during an outage?
Start by listing the appliances you need most. Check both their running watts and the extra power they need to start. A refrigerator, for example, may need much more power for a moment when its compressor kicks on.
Here is an example, not a test of this generator: a refrigerator using 600 running watts, plus 100 watts of lights and 100 watts for a router and other small devices, adds up to 800 watts. If that refrigerator needs 1,800 watts to start, the total briefly reaches 2,000 watts. Your appliances may use different amounts.
That example is within the listed gasoline running and starting ratings. You still need to check your own refrigerator, each outlet’s limit, and anything else that may turn on at the same time. If you use propane or natural gas, check those ratings separately.
A 1,500-watt heater uses a lot of power on its own. Follow its connection instructions; many portable heaters must plug directly into a suitable wall outlet. For a well pump or central air conditioner, have an electrician check voltage, running power, and startup demand. A 240V outlet alone does not guarantee enough power.

What we like and what to consider
Reasons to consider it
- Runs on gas, propane, or natural gas.
- 14,500 running watts on gas.
- 240V output for compatible appliances or a professionally installed home connection.
Things to keep in mind
- It weighs 348.3 lb. (157.9 kg). Make sure you can move and store it.
- Switching to propane reduces running power to 13,000 watts.
- Noise figures depend on the distance and how hard the generator is working.
What owners are saying
We do not have enough owner feedback for this exact model to give a fair summary. Reviews for a similar generator, or another option on the same Amazon page, may describe a different machine. Before buying, check recent reviews for the full model number and find out how the seller handles service and returns.
Starting, moving, and maintenance
The listed starting options are: electric, remote. Keep the starter battery charged as the manual recommends. Practice any backup starting method before an outage. It weighs 348.3 lb. (157.9 kg). Wheels can help on level ground, but they do not make stairs or lifting into a vehicle easy.
The listed warranty is 3 Year Limited. Read the full terms, including whether your seller and intended use are covered. Follow the manual for oil type, oil changes, and storage. Keep track of running hours during a long outage. See our maintenance guide →

WEN TF-1450X →
This large three-fuel generator provides 8,750 running watts on natural gas. That is much less than its 14,500-watt gasoline starting number, so use the right fuel rating when planning. A natural-gas adapter is included, but the hose costs extra.

GENMAX GM15000ET →
This GENMAX runs on gas, propane, or natural gas and provides 11,000 running watts on gas. It is a conventional generator, not one of the brand's inverter models. Its two-wire start feature does not replace the equipment or installation needed to connect it safely to a home.

Questions about the Westinghouse WGen14500TFc
How much running power does it provide?
14,500 watts on gasoline; 13,000 watts on propane; 11,600 watts on natural gas. Starting watts are only available briefly, not for steady use.
Is it an inverter generator?
No. It is a conventional generator. A voltage regulator does not make it an inverter. Check your electronics’ power requirements before connecting them.
Can I use it in a garage if it has CO shutdown?
No. Never run a generator in a garage, even with the door open. Use it outdoors at least 20 feet from homes and openings, with exhaust pointed away. Carbon monoxide shutdown is extra protection; it does not make indoor use safe.
Can I connect it to my house?
Its 120/240V output may work with a suitable home connection. Have an electrician choose and install the right transfer equipment and check the generator’s wiring setup. Never connect a generator to a household wall outlet.
Should you consider the Westinghouse WGen14500TFc?
This big three-fuel generator is worth considering when smaller models cannot cover the appliances you need. It is heavy, so plan how you will move and store it. Each outlet also has its own limit; one cable cannot carry all 14,500 running watts.
