Description

Zoom on the WEN TF1450

In short, the WEN TF1450 is a powerful portable generator adequately designed for:

  • Professionals in need of safely powering high-intensity work or lighting equipment
  • Homeowners in need of an emergency backup power for their essentials

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.

Power & Run Time

The WEN TF1450 delivers 120/240V and is equipped with a tri-fuel technology, enabling it to operate on gasoline, propane, or natural gas. When powered by gasoline, it achieves a running wattage of 11,500W and a peak wattage of 14,500W. Switching to propane provides 10,300 rated watts and 12,500 peak watts, while natural gas operation delivers 8,750W of rated wattage and 10,500W of starting wattage.

This generator features a standard recoil pull-rope starting mechanism and also a convenient and efficient electric starter (battery included).

The TF1450, with a fuel capacity of 8.2 gallons, reaches a run time of around 12 hours at 50% load utilizing gasoline (fuel consumption around 0.68 GPH). Alternatively, it can reach a run time of around 6 hours (on a 20 lbs tank - propane consumption around 0.78 GPH) with propane.

Outlets

The control panel includes the following 6 AC outlets:

Two Duplexes 120V 20A (5-20R)
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

It also sports 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle providing easy battery charging capabilities.

Since it boasts a twist-lock L14-30R receptacle, the TF1450 is engineered to be transfer switch ready, ensuring easy integration with your breaker box to provide backup power to your home during outages.

Portability

With dimensions of L28.8 x W28.3 x H25.8 in, the traditional open frame design of the WEN TF1450 ensures stability while allowing easy maintenance access to components and promoting effective air cooling. This type of design is ideal for tough environments and heavy outdoor use.

While weighing 224.9 lbs, the generator is classified as 'portable,' indicating its mobility, albeit its heftiness may limit portability in specific situations. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit and its folding handle, once it is placed on the ground.

The TF1450's control panel

The TF1450 and its control panel include a convenient meter, displaying voltage, frequency, and lifetime hours information. This feature comes handy when monitoring its status and activity.

In addition to this info, the generator's light indicator provides visual feedback when its oil levels are insufficient.

Featuring a built-in fuel gauge, the generator offers quick, convenient, and easy gas level checks at a glance.

Considering security aspects, the generator boasts an overload protection (circuit breaker) and an automatic low oil shut-off, offering peace of mind throughout operation.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the WEN TF1450, the following accessories are also included: oil, tool kit, funnel and propane hose. An official storage cover is also available, as a separate purchase.

The WEN TF1450 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the WEN TF1450 compare to multi-fuel generators of similar power (between 10000 and 14000 W).

  • In terms of its dry weight, the WEN TF1450 stands at only 224.9 lbs, meaning that is one of the lighter multi-fuel devices of the 10000-14000 rated wattage category if you wish to prioritize weight, the DuroStar DS13000MX is one of the top contenders in its power category, weighing only 209 pounds.
  • In terms of run time, the TF1450 surpasses similarly powerful multi-fuel devices, boasting one of the higher run times at around 12 hours. If run time is one of your main concerns, the Predator 13000 could be worth looking at. It boasts one of the highest run times among units of comparable power, lasting around 12.1 hours.
  • Run time is a key metric, but it's dependent on the generator's fuel capacity. Therefore, discussing fuel efficiency is necessary to get the full picture. This generator has one of the best fuel efficiency when compared to other units in the aforementioned output range, consuming approximately 0.68 GPH (gallon per hour) at 50% load.
