Zoom on the WEN 56125i

To sum up, the WEN 56125i is a quiet, compact and lightweight portable inverter generator tailored for:

  • Camping and tailgating hobbyists looking for a portable power source
  • Amateur DIY lovers

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.

Power & Run Time

Running on gasoline, the WEN 56125i utilizes a 60 cc WEN OHV 4-stroke engine to deliver 120V, offering a running wattage of 1,000W and a starting wattage of 1,250W. In addition, the parallel capability (WEN 56421 Parallel kit (opens in a new tab) not included) empowers doubling of power output when linked to another similar or compatible unit, ensuring expanded energy capacity and reliability for various applications.

Presented in our list of the 10 quietest portable generators for its low noise rating of 51 dBA (just slightly more noisy than rainfall), the inverter generator features a conventional pull-start mechanism.

The 56125i boasts a fuel tank capable of holding 0.69 gallon, allowing it to run continuously for around 5 hours at 50% load (with fuel usage averaging around 0.14 gallons per hour).

Featuring a <1.2% Total Harmonic Distortion (THD), the 56125i delivers a clean sine wave, guaranteeing the safety of your sensitive electronics plugged into its AC outlets.


The control panel is equipped with the following 2 AC outlets:

Duplex 120V 20A (5-20R)

In addition, it provides 2 DC outlets: there's two 5V USB ports with which charging of electronics like mobile phones and tablets is made convenient.


The WEN 56125i is distinguished by its enclosed inverter generator design (L17 x W9 x H16.5 in), providing improved aesthetics and quieter performance compared to traditional, open frame units. The generator has a contemporary design, convenient for recreationally generating power.

The 56125i boasts a weight of merely 31.6 lbs, solidifying its reputation as a lightweight, easily transportable generator. The device can be easily moved by just one person and thus, its power may be enjoyed on-the-go. Further convenience is provided by its handle (molded in the case), as it allows you to carry it with great ease.

Good to know: This unit ranks 6th in our list of the 10 smallest portable generators.

The 56125i's control panel

Some light indicators allow you to instantly see if its oil levels are insufficient, the generator is ready and the generator is on overload.

As far as security is concerned, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during use.

As for its accessories, apart from the previously mentioned features, the WEN 56125i also comes with the basic documentation and an owner's manual (opens in a new tab), allowing you to start it right away.

The WEN 56125i versus other generators

The following charts are provided to give you an idea of how some of the key specs of the WEN 56125i compare to inverter generators of similar power (between 1000 and 2000 W).

  • Regarding weight, the WEN 56125i comes in at only 31.6 pounds, positioning itself as one of the lighter options among inverter generators spanning from 1000 to 2000 in rated wattage. if you wish to prioritize weight, the Pulsar PGD16iSCO is one of the top contenders in its power category, weighing only 24 pounds.
  • This inverter generator offers a rated noise level of 51 dBA, placing it among the quieter alternatives in its type and power category. If you are concerned with noise, check out the Honda EU2200i, which is one of the least noisy generators in its power range, with a noise rating of just 48 dBA.
  • In terms of autonomy, the 56125i offers around 5 hours at a 50% load, placing it at the lower range within its type and power range. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Westinghouse iGen2200, boasting with around 10 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This inverter generator has a better fuel efficiency than other units in the aforementioned output range, consuming approximately 0.14 GPH (gallon per hour) at 50% load. If you're placing a high priority on fuel consumption, the Pulsar PGD16iSCO, with a low fuel consumption rate of 0.09 GPH, could be an option to consider.

Price comparison

As you can see from these interactive charts, when compared to other 1000-2000W inverter generators, the WEN 56125i is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.

The bottom line

  • Inexpensive
  • Parallel capable
  • Inverter
  • Lightweight (31.6 lbs)
  • Quiet for its power (51 dBA)
  • Fuel efficient
  • No data center
  • Relatively low run time
