Zoom on the WEN DF1100T
In summary, the WEN DF1100T is a powerful portable generator especially useful for:
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Professionals in need of safely powering high-intensity work or lighting equipment
- RV travellers looking for even more independence
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The dual-fuel technology of the WEN DF1100T allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 8300W and a starting wattage of 11000W. If propane-powered, it gives 7500 rated watts and 9500 starting watts.
This generator features a simple traditional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included).
As for its running time, the DF1100T, along with its 6.6 gallons fuel capacity, can run for around 8.5 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.78 GPH). If propane is used, it can operate for around 3 hours (on a 20 lbs tank - propane consumption around 1.57 GPH).
Since the DF1100T has a somewhat high THD (<15%), it is advisable to not use it for the powering of sensitive electronic devices.
The control panel features the upcoming 6 AC outlets:
In addition, it provides 1 DC outlet: there's a 12V 8A receptacle with which you may charge your batteries with ease.
If you own an RV with a 50-amp service, you can consider this WEN unit as RV-ready, as it features a 14-50R outlet. Its L5-30R receptacle can also be used for a simple RV connection with an L5-30P to TT-30R adaptor.
The design of the WEN DF1100T is a typical, open frame, with the dimensions of L27.3 x W20.6 x H21.9 in, offering support and stability and enabling the possibility of raising it above ground level. The design is ideal for rough environments and demanding outdoor use.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 213.8 lbs make it incredibly difficult to manually lift and transport. Nevertheless, thanks to its wheel kit and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.
The DF1100T's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the WEN DF1100T also comes with some accessories: oil and propane hose are included. An official storage cover is also available, as a separate purchase.
The WEN DF1100T is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
Moreover, it features a spark arrestor and therefore, can be used in forested areas.
The WEN DF1100T versus other generators
The following charts are provided to give you an idea of how some of the key specs of the WEN DF1100T compare to dual fuel generators of similar power (between 7500 and 8500 W).
- As its weight is 213.8 pounds, the WEN DF1100T falls in the expected weight range of the dual fuel devices in the 7500-8500 rated wattage category. Regarding dry weight, one of the champions in the same power range is the Cummins Onan P9500df, with a dry weight of only 194 lbs.
- The DF1100T's autonomy is somewhat low end compared to devices of its type and power range, as it reaches only around 8.5 hours at 50% load on a full tank. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Firman H07552, reaching around 12 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.78 GPH. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Pulsar PG10000B16. With a fuel consumption of as little as 0.55 GPH, it is one of the most efficient generators currently on the market.
As you can see from this interactive chart, when compared to other 7500-8500W dual fuel generators, the WEN DF1100T is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
