WEN is a reputed company which has been in the electrical appliances market for over 6 decades.

It specializes in a variety of appliances, from power tools to portable generators. Its portable generators, in particular, are generally well-received by customers, being seen as good-quality and economical options.

One such generator is the WEN 56200i inverter generator, capable of producing a surge power of 2000W and a running power of 1600W.

As an inverter generator, it is extremely quiet and is capable of producing an extremely steady output.

This means that not only can the WEN 56200i be used to power general household appliances or power tools but it can also be used for sensitive electronic items such as laptops, tablets, or mobiles.

This makes it extremely useful for back-up during power outages as it can provide electricity for a wide variety of usages.

Design, Dimensions & Weight

As it is an inverter generator, the components are kept hidden from view inside a hard plastic casing.

It has an extremely efficient design and comes with an attached handle as part of the design which can make it easy to carry.

It is indeed light enough to be carried with just the handle, and as such, no mobility kit is sent with the model or sold by WEN.

Its shipping weight is 54.4 lbs, which means that it is easy to move around without much strain.

In terms of dimensions, it has a length of 20.25 inches, a width of 12 inches, and a height of 19.25 inches. This means that none of its sides exceeds 2 feet in length, with its width being particularly narrow.

This compactness in size is coupled with its shape, which is fairly cuboidal, somewhat resembling a suitcase in its overall construction.

This shape means that it is easy to stow away during storage or for transport without taking up too much space.

WEN itself has not uploaded an official video of this model but a popular user-uploaded video is available which can give you a comparative idea of its dimensions:

Power Output / Generation

The WEN 56200i has a 4-stroke OHV single cylinder engine with a forced air cooling system.

For many users, this information is generally of little use except to know that while looking for engine oil, only oil which is appropriate for a 4-stroke engine should be used.

For general use, i.e. above 40˚F, the manual for the model recommends a 30W, 4-stroke synthetic oil.

For more varied temperature ranges, there is a detailed chart given in the manual which provides information on which oil is best for the engine across which temperature range.

As stated above, this generator is capable of generating a surge wattage of 2000W and a running wattage of 1600W.

It is thus capable of running a number of small electrical devices or even lights and fans for a number of rooms in case of an emergency.

If this wattage is low for you, you can also opt to connect two units of this model in parallel to double the amount of wattage available to you.

While its fuel tank only has a capacity of 1 gallon, it is an inverter generator which means that its engine can modify its speed to suit the load on the generator.

This increases its efficiency and allows it to last longer than traditional generators on the same volume of gasoline.

Fuel and Noise

The fuel for this model is unleaded gasoline with a minimum octane rating of 87. This should not have any impurities mixed into it, including dirt, water, or even oil.

Furthermore, the gasoline should not be stale – i.e., it shouldn’t have been left open for more than 30 days.

On a full tank of fuel, this model is capable of running for 6 hours on a half-load.

Furthermore, this model is CARB compliant, which means that it can be used in all 50 states.

Inverter generators, in general, tend to be quieter than traditional generators and this one is no exception, having an extremely low noise level.

The manual gives a variable decibel rating, depending on the load, with it having a noise level of 51 dB at a quarter load and 55 dB at ¾ load. These values are measured at a distance of 22 feet.

Display & Control Panel

The display on this model is fairly straightforward, with warning labels being placed on the top and on one side to familiarize new users with operating procedures.

The control panel is extremely centralized, with all the controls being present on it. At the same time, it is quite compact which means that the controls are slightly smaller and the labelling font is not very large.

The following controls can be found in the control panel :

  • 3-in-1 switch: functions as the engine switch and the choke lever
  • Eco-Mode switch: allows you to turn the eco-mode on and off
  • Circuit breaker
  • Parallel connection ports: used if you desire to connect two units of the model in parallel
  • Grounding nut: consult local regulations before grounding your generator
  • 4 outlets: a 120V AC duplex receptacle, a 12V DC receptacle, and a USB charging port

Startup and Shut down

This model has a manual starting procedure and no electrical starting option. Before starting the generator ensure that no loads are plugged into it, ensure that it is properly grounded and that the fuel and engine oil level is sufficient. After this, perform the following steps :

  • Rotate the vacuum relief valve on top of the fuel cap to the ON position
  • Turn the 3-in-1 switch to CHOKE
  • Slowly begin to pull the recoil starter cord until resistance is felt. Then pull sharply.
  • As the generator begins to turn on, slowly turn the 3-in-1 switch to its ON position
  • Before plugging in any electrical devices, let the generator run for several minutes so that its temperature and speed can stabilize.

To turn off the generator, first, unplug all electrical loads and let it run for a few minutes. This will allow it to stabilize its internal temperature and engine speed. Then follow these steps :

  • Turn the 3-in-1 switch to OFF
  • Rotate the vacuum relief valve on top of the fuel cap to the OFF position

Additional Features

While this model is generally quite efficient and a good-quality inverter generator, it doesn’t have many additional features except for its Eco-Mode.

The Eco-Mode, which can be turned on from the Eco-Mode switch on the control panel, allows the generator to accurately match its engine speed to the load, dramatically increasing its efficiency.

However, there is a definite setback as the load must be below 1000W to use this mode.

If your load is higher than 1000W then the Eco-Mode should not be used.

Warranty & Repairs

WEN offers a two-year limited warranty for the WEN 56200i.

This means that warranty is applicable for two years from the date of purchase for generators used privately while it is only 90 days from the date of purchase for generators used for commercial or rental purposes.

To register for the warranty you must fill out the warranty card details and mail them to the given address along with a proof of purchase.

The warranty covers parts and labour for any malfunctioning of the generator within the given warranty period. It should be noted, however, that labour is provided only for the 48 contiguous states in America.

To avail of the warranty, do not take the generator to the retailer but rather contact WEN’s customer service, which will instruct you accordingly. If you have to ship the generator to them then you will have to bear the initial shipping charges.

If and when you ship the generator to them, you must include a copy of your warranty card, proof of purchase, and a detailed description of the problem that you are facing with your generator.

Care and Maintenance

Regular care is integral to maintaining your generator, with regular maintenance enhancing the lifespan of your unit.

Procedures such as periodically changing the engine oil or replacing the spark plug make sure that the generator remains in running order and that no safety risks are posed by its usage.

Furthermore, improper maintenance can null your warranty. Thus, any issues which occur out of negligent maintenance and care cannot be fixed free of cost.

As such, maintenance is quite an important aspect of generator use.

The manual of the WEN 56200i recommends the following schedule :

  • As required: change engine oil, change the spark plug
  • Every 8 hours or daily: drain carburettor, check engine oil level, check fuel level
  • Every 25 hours: replace engine oil, check air cleaner cartridge
  • Every 50 hours or 3 months: Replace engine oil
  • Every 100 hours or 6 months: check and clean air cleaner cartridge, check and clean the spark plug
  • Every year: change spark plug, clean fuel tank
