WEN 3500 Watt Port. Gen.

The WEN 3500-Watt Portable Generator with Wheel Kit (Model WEN 56352) is an intermediate weight, long running, mid range workhorse at the 3000 watt size range (3500W Starting). It’s a top seller for portable generators in this range on Amazon.

This a great generator for emergency backup and can handle 3000W running power, which will power the majority of your home appliances to keep your fridge and freezer working during a long power outage.

It’s also a good wattage size for powering tools and other appliances at job sites or in RV parks. It’s a little on the heavy side, but at 104 pounds is movable with a couple of strong folks doing the lifting. The wheel kit and leverage handles make it easy for a single person to pull it around your house, site or park.

Power Output and Generation

The WEN 56352 is powered by a 208cc 7-HP OHV Gas-Powered engine which is NOT CARB compliant. It runs at 3600 rpm which is an easy generator speed, but can have a tendency to be a bit nosier, but in this case not too bad.

It generates 3000 watts of rated/running power, It has a 3500 watts as surge capacity. The engine ignition system is a non-contact transistor setup for minimal wear on parts. (Often called electronic ignition)

It has two 120V duplex plugs (NEMA 5-20, one 240V/120V twist lock 4 prong plug (NEMA L14-30R) as well as one DC 12V (8.3 amp max) car style receptacle and is protected against overloads by an in-line fuse located behind the control panel. Note that the voltage level on this DC output can be over 18V, so make sure you’re not working with any ultra sensitive devices.

7HP Engine

For AC, with a maximum of 3000 running watts provides 25 amps at each 120V plug (in the 120V switch position). The switch and plugs are setup such that if you switched into the 240V position and use the 120V plugs you will have 12.5 amps at each outlet. Effectively you may think of it as half as much power at each plug.

Additionally the output is US based 60 HZ and single phase which is typical of all household appliances. Construction and commercial users take note. You won’t be able to run the larger horsepower 3 phase motors with this unit.

Fuel Type and Noise Levels:

WEN 4 Gallon Gas Tank

4 Gallon Gas Tank – 11 hrs @ 1/2 Load

The WEN 3500 watt generator uses standard (engine type) Unleaded Gas and has a capacity of 4 gallons. and 87 octane rating is required at typical lower elevations, but can be lowered a point or two for higher elevations, but you may prefer to use the higher octane for running smoothness..

There is no oil mix requirements for the gas and oil is handled by the fill at the crankcase using the common 10W-30 although 5W-30 will work. WEN indicates that starting temperature will affect oil consumption and for working in above 40 deg F you should check your oil more often. .

One tank of fuel can run this generator for over 11 overs at half load. That’s enough to keep your essential appliances up and running. Customers have indicated that they’ve gotten over 15 hours overnight on very light duty and had more than a quarter of a tank left.

Noise levels are given for a 22 foot radius and rated at 67dB when idling and 74dB fully loaded. That’s a tight range and generally around a noise level of a nearby highway. Current customers are indicating that it’s quieter than expected, but still present when in use. You won’t want it near your patio when you’re trying to have a conversation.

Care and Maintenance and Use


WEN’s manual has a section on using the generator which details do’s and don’ts such as making sure that if you’re wiring a transfer switch to the house you have it done professionally. The section on figuring watts and wire sizes is sufficient to allow most people to understand the basics of what it will power and how to connect devices.

There is an interpretation that the unit should only be used at 2400 watts based on normal wire sizes. However, if you get 10 gauge wire you can get the full benefit of the 3000 watts. Here is an example of a splitter in that category. (this is only an example and you must follow the manufactures guidelines)

Consumer Comments

This generator gets a superb rating as a portable generator at Amazon.com. As of this writing it was getting a 4.7 out of 5 starts with 68 reviews. 95% were giving it a 4 star and up rating.

Customers generally comment on the ease of use, the right size and price point for their needs. Most agreed that they were able to power everything they needed, but didn’t expect it to be the whole house forever needs. Those doing research found this to be a winner for overall needs and economy.

In everyday use the users are indicating running tools and equipment without any issues. It starts in 1 or 2 pulls and is easy to move around. A construction crew bought several of these and has had excellent luck with them. Because of the heavy use there was a bit of a problem with bolts and wheels coming loose, but could be easily cured with some Loctite.

One customer remarked, during the aftermath of huricane Sandy they had nearly 300 consecitive running hours except for shutting down for fuel and maintenace. It was powering up the house and burned about 6 gallons of gas every 24 hours. Compared to the published run time of 4 gallons in about 11 to 12, it’s running well on about 1/3 power level.

Customer service responses have been excellent. As with any mass produced product there are going to be problems and broken parts from the start. For the few having these problems, service has been excellent. What was a surprise is that WEN was willing to send parts for your own installation without having to go to a service center. For most of us that are handy enough to work on these machines that’s a great benefit.

Pros & Cons


  • Wheel kit for a Medium wieght at 104lbs (128lbs with gas) making it easily movable and can be loaded with a couple of people doing the heavy lifting.
  • Good economy on fuel consumption verified by customers at around a 2 to 3 hours per gallon at half load.
  • Easy pull start.
  • Up to 3000 watts of power can power most emergency needs and construction setups.
  • Can be used with transfer swtich set up to house, however, may not the best setup because of the limits on amps, but it is workable if needed.
  • Size makes it easily stored and transportable.
  • Voltage switch is nice as it is not often found on other generators.
  • Relatively low noise.
  • Great pricing for this size generator.
  • Getting parts and service is excellent


On the negative side there are a few issues.

  • Several instances of factor quality control on broken parts not related to shipping. However, majority of customer service experiences have been very good.
  • For the 240V switch position the two 1500 watt windings are connected in series meaning you can only get 12.5 amps from any of the 120V plugs. (note that in the 120V position allows the winding to be in parallel and you can get a full 25 amps from the 120V plugs. This means you’ll need to be sure not to overload any one plug and if you’re not using 240V your generator will be better off not working as hard in the 120V position.
  • May need to add some thread compound to take care of loose mounting bolts or wheel kits.
  • No grounding wire or rod
  • Oil fill is poorly placed a flexible funnel is needed to get to it easily

The WEN 3500 Watt Portable Generator is a top seller and highly rated by the users. It provides 3000 watts of rated power and 3500 for starting watts.It will power a good number of appliances and power tools.

One Carpenter recommended it for typical job applications for both the power available and the economy of operation. The value proposition for this unit at the $300+ range is exceptional. Don’t expect frills and added features, this is a simple solution as a basic work horse and emergency generator.

It’s relatively quite compared to larger generators, but still produces enough noise that you’ll want to give yourself some distance as far as working around it or keep it away from your main living area’s.
