Westinghouse WGen7500 Features and Specifications

With its physical dimensions of (L x W x H) 27.2 x 26.1 x 26 inches (~691 x 663 x 661 mm) and its weight of 192 pounds (~87 kg) dry, Westinghouse WGen7500 is a well balanced 7500/9500W unit.

Westinghouse WGen7500 is powered by a four-stroke 420cc air-cooled, 13 HP OHV engine operating at 3600 RPM and featuring a nominal noise level of ~73 dB, which is a good result for an open-frame generator in this price/power class.

The unit features 7500 Running Watts and 9500 Starting Watts, ensuring plenty of power, even when running tools and appliances that require more power when starting.

Westinghouse WGen7500 is not a parallel-ready unit, but with 7500/9500 watts, it can power even smaller households easily.

fuel gauge

The Unit comes with 6.6 gallons (25 liters) fuel tank featuring a fuel gauge and ensuring runtime of:

- @25% load: 16 hours @1875W, fuel consumption of ~0.22 gal/h/1000W,

- @50% load: 11 hours @3750W, fuel consumption of ~0.145 gal/h/1000W.

Westinghouse WGen7500 features several starting methods:

- classic manual recoil starting system, used as a backup,

- electric starting system via start button,

- remote starting fob with a maximum range of ~100 meters,

- automatic start via Westinghouse ST Switch (Amazon link, opens in the new window) sold separately.

westinghouse st switch

Westinghouse ST Switch enables the user to connect up to 2400W of appliances via two 120V 5-20R outlets that are automatically powered by the Westinghouse WGen7500 or similar compatible power generator in the case of blackouts.

While having a whole house transfer switch and the whole house power generator is a more convenient solution, it is also much more expensive than having the Westinghouse ST Switch/WGen7500 combination.

Note: Westinghouse WGen7500 portable power generator is a relatively simple unit to use and maintain, but when it arrives, be sure to read the documentation that comes with the unit (User's Guide, Warranty Terms, Maintenance Guide) thoroughly - better safe than sorry.

control panel

The control panel is simple and straightforward and it includes:

- Electric Start Push Button,

- Battery On/Off Switch,

- Battery Charging Port and Indicator,

- Data Center Display (volts, frequency, lifetime hours),

- Main Breaker,

- Smart Switch Ready Port,

- Ground Terminal,

- 1x L14-30R 120/240V 30A receptacle,

- 2x Duplex GFCI 5-20R 120V 20A receptacles.

How to Charge Westinghouse WGen7500 Generator Battery

Westinghouse WGEN7500 power generator comes with a 9Ah rechargeable battery (Part Number 51108) used for electric, remote, and/or the automatic start of its engine.

battery charger

When the engine is working, a small charge slowly charges the battery, requiring no intervention from the user.

But, the Westinghouse WGen7500 power generator also comes with a separate battery charger, allowing the user to charge the battery using the wall power outlet when the unit is stored for a longer period of time.

Note: for the battery to successfully start the engine, it must be charged, the battery must be properly hooked up and the battery switch on the front panel must be in the On position.

Westinghouse WGen7500 THD Levels

Westinghouse WGen7500 is not an inverter power generator and features THD levels of ≤23%, making it suitable for powering various tools and non-sensitive appliances.

For sensitive appliances, the use of voltage stabilizers, with or without surge protectors, is recommended.

Thanks to the pair of 10-inch (25.4 cm) wheels, Westinghouse WGen7500 is a portable power generator, allowing the user to manually reallocate the unit via a foldable handle.

Westinghouse WGen7500 doesn't feature a low oil warning or overload indicator, but it comes with automatic low oil shutdown, automatic voltage regulation, and overload protection. Also, power receptacles are covered, protecting them from dirt and, up to the point, splashing water.

Westinghouse WGen7500 comes with a residential warranty of 3 years or 1000 working hours, and with a commercial warranty of 1 year or 1000 working hours.

Also, Westinghouse WGen7500 portable power generator is EPA-approved and CARB-compliant, allowing it to be sold in all 50 states, including California.

Westinghouse WGen7500 Generator Submodels

Westinghouse manufactures several very similar portable open-frame power generators, including (Amazon links, open in the new windows):

- Westinghouse WGen7500 is a portable, open-frame, power generator, reviewed in this article,

- Westinghouse WGen7500DF is very similar to the Westinghouse WGen7500 power generator, but it supports the use of both gasoline and propane (LPG) gas. Since LPG can be easily stored for a longer period of time, this model is recommended for people who need a 7500/9500W power generator for emergencies and blackouts.

- Westinghouse WGen7500c is very similar to the Westinghouse WGen7500 power generator, but it also features a Carbon Monoxide (CO) sensor, hence the "c" as part of its label. While Carbon Monoxide (CO) sensor provides an additional layer of security, don't forget that the power generators MUST be operated outside, regardless of the Carbon Monoxide (CO) sensor or not.

- Westinghouse WGen7500DFc is very similar to the Westinghouse WGen7500DF power generator, but it features a Carbon Monoxide (CO) sensor - practically, this model is a basic WGen7500 power generator with a dual-fuel option and Carbon Monoxide (CO) sensor.

Personally, having a Carbon Monoxide (CO) sensor is great, but more importantly is to use power generators (all power generators, not just Westinghouse WGen7500) as intended.

Again, the power generator should be placed outside, down the wind - this cannot be emphasized enough...

For example, if the power generator is placed up the wind, the wind could cause Carbon Monoxide buildup away from the power generator, potentially causing serious health issues (or even death!), but without triggering the Carbon Monoxide (CO) sensor on the power generator itself.


Lwgen7500 mong Story Short: Westinghouse WGen7500 is an open-frame, portable power generator, featuring 7500 Running Watts and 9500 Starting Watts, allowing it to power various tools and appliances for a longer period of time.

The unit is simple to use and maintain, but it has to be maintained properly in order to operate reliably, just like any other power generator.

Also, a remote starting fob can come in very handy in many situations.
