That being said, it can run everything you want to throw in it at your home. At job sites, you connect multiple power tools to run at the same time.

You can power all your big boys at home from fridge, air condition, microwave, pump, HDTV, multiple lights, even computers, laptop, phones and many more. Yes, you read it right, it includes your sensitive gadgets and we’ll discuss more about it later.

Ease Of Use

If you think that operating this kind of huge generator is hard, well it is not. The panel is laid in a very simple presentation for easy operation.

This includes a pair of 120v GFCI 5-20R regular home AC outlets in duplex. An L14-30 30A Receptacle, L4-50R 50A Receptacle and 14-50R 120/240V 50A receptacles.

Starting this ultra-duty beast makes it super easy for you. It features a push button electric start and a remote start by means of a key fob for your convenience. It enables you to start this generator at a distance up to 109-yards away from the unit.

It a good thing to know that you can now start or stop the generator while you’re lying from the comfort of your bed. This generator features a remote start and stop in the form of key fob. You can also start the generator using a push button located on the front panel while operating it.

It is very rare to have a huge generator which is a CARB compliant. Mostly high power generators are non CARB compliant due to its bulky engine that results in vast emission of smoke. To my surprise, this generator is an exception as it produces clean fumes that doesn’t harm your family.

Therefore, it can be ship and use in California to enjoy its benefits. Not only that, the WGen12000 is a CSA and EPA compliant that doesn’t produce too much noise for freely usage in any National park.

Built And Portability

The Westinghouse WGen12000 is built with top grade materials to withstand your toughest power requirements. Made from hardened steel frame body construction with Ultra-Duty engineered for maximum strength.

Though, this thing weighs heavy it features a pair of wheel kit that makes it easy to roll in all kinds of terrain. The addition of mags adds to its nice looks and durability as well. To provide you with total portability it comes with a pull-up handles for easy maneuver and move around.

Easy Maintenance And Safe To Your Appliances

To keep your generator in good shape for a long time you need to properly maintain it. This includes changing the engine oil periodically. With its hour time used feature which is included in the VFT display you can easily schedule it.

The VFT Data Center consists of voltage, Frequency and Time used as I stated earlier. The voltage display ensures the ideal output power. Running your appliances under or over voltage can possibly harm it. Therefore, it is always a good thing to know the right voltage for your appliances safety. This works the same as the output frequency which you can also verify here.

Some of the WGen12000 safety features are the Automatic Voltage Regulator (AVR) to keep a steady output voltage. While the Automatic Low Oil Shutdown feature prevents the generator’s motor from overheating due to deficient oil supply.

The Smart Idle Control let you save fuel when the generator is not in use while running. For extra safety of your appliances there is an Overload Protection in the form of Circuit Breaker. It will automatically cut off the power whenever it senses an overload or short circuited.

You can safely use it with your sensitive appliances and gadgets such as HDTV, computers, charging phones, laptops, cameras and many more without harming it. Westinghouse claims a less than 5% (THD) Total Harmonic Distortion on this generator which is almost the same as your regular home AC outlets.

The addition rubber cover on the outlets is worth mentioning here. This safety feature prevents you from accidental touching the unused live terminals of the outlets while the generator is running. This is ideal if you have children at home. Its terminal is also protected from possible corrosion that leads to loose contact.

Fuel Consumption And Run Time

The WGen12000 comes with huge tank that can be filled with 10.5 gallon of fuel which is equivalent to 42 liters. Having a large fuel tank gives you advantage that provides you with longer run time without frequently filling it. This will save you from trouble during power outage in which you need to go out and buy fuel to refill it.

If you fill this generator with fuel at full tank it will lasts up to 16-hours of run time provided with 50% load on it. This will take you even longer if your load is less than 50%. Otherwise, if you put more than that it may shorten its run time.

The generator also features a Fuel Gauge so that you can check the remaining fuel to continuously run it without stopping. It lets you fill the tank before it runs out of fuel and eliminate the guessing game.

Setting Up And What’s Included
