Zoom on the Powermate DF3500E

In a nutshell, the Powermate DF3500E is a portable generator mostly geared towards:

  • RV travellers looking for even more independence
  • DIYers who wish to improve their efficiency with tools
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

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 Powermate DF3500E in use

The Powermate DF3500E

Thanks to its dual-fuel technology, the Powermate DF3500E delivers 120V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 3500W and a peak wattage of 4375W. When propane-powered, it has 3200 rated watts and 4000 peak watts.

The generator is rated for a noise of 68 dBA (less noisy than an office). Its starting mechanisms include a conventional pull-start mechanism and a simple and elegant electric starter (battery included).

With a fuel capacity of 4.5 gallons, the DF3500E can operate for around 10 hours at 50% load using gasoline (fuel consumption around 0.45 GPH), or for around 7 hours (on a 20 lbs tank - propane consumption around 0.67 GPH) using propane.

The generator will allow you to simultaneously power various devices, for example:Note: All of these devices might not start simultaneously. Provided examples are based on a maximum load of 75 % and estimated wattages. With the help of our wattage calculator you can find out if this product suits your requirements.

Outlets

The control panel provides the upcoming 4 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (TT-30R) receptacle
120V 30A (L5-30R) receptacle

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Powermate generator is RV Ready.

Portability

The dimensions of the Powermate DF3500E, which are L26.3 x W23 x H20.7 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 115.5 pounds. However, its challenging mobility is solved by a wheel kit and a folding handle, which will ease its displacement, once it is on the floor.

Features

The DF3500E's control panel

To help you monitor the DF3500E's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

While the standard documentation and a user manual, helpful for starting the device promptly, come with the Powermate DF3500E, the following accessories are also included: propane hose, funnel, oil and tool kit.

Emissions

The Powermate DF3500E is neither EPA approved nor CARB-compliant..

However, it features a spark arrestor and thus, may be used in forested areas.

The Powermate DF3500E versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Powermate DF3500E compare to generators of similar power (between 3000 and 4000 W).

  • As its weight is 115.5 pounds, the Powermate DF3500E falls in the expected weight range of the devices in the 3000-4000 rated wattage category. If weight matters to you, one of the champions in this power range is the Generac GP3500iO with only 74.3 pounds.
  • Because this generator emits noise as low as 68 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. For those who are looking for a less noisy device, we suggest the Westinghouse iGen4500. With just 52 dBA, it is one of the most quiet devices in this power range.
  • Regarding its autonomy, the autonomy of the DF3500E, reaching 10 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Honda EB4000, which is able to run for 16 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 0.45 GPH. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.

Price comparison

As you can see from this dynamic chart, when compared to other 3000-4000W generators, the Powermate DF3500E is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
