Description
Zoom on the WEN 56125i
In a nutshell, the WEN 56125i is a quiet, compact and lightweight portable inverter generator mostly geared towards:
- Camping and tailgating hobbyists looking for a portable power source
- DIYers who wish to improve their efficiency with tools
Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.
Power & Run Time
The WEN 56125i houses a 60 cc WEN OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 1,000W along with a peak wattage of 1,250W. Furthermore, the parallel capability (WEN 56421 Parallel kit (opens in a new tab) not included) offers the advantage of doubling power output when connected to another similar or compatible unit, delivering expanded energy capacity and flexibility for various applications.
Enjoying a low noise rating of 51 dBA (just slightly more noisy than a quiet suburb) which earned this unit its place in our list of the 10 quietest portable generators, it gets running thanks to a standard recoil pull-rope starting mechanism.
With its 0.69 gallon fuel tank, the 56125i can operate for around 5 hours at 50% load when fully fueled (with fuel usage averaging around 0.14 GPH).
Delicate electronics can be plugged in the AC outlets safely, as the 56125i generates a clean sine wave, reaching a <1.2% Total Harmonic Distortion (THD).
Outlets
The control panel features 2 AC outlets as follows:
Additionally, it features 2 DC outlets: there's two 5V USB ports designed for hassle-free charging of various electronic devices such as smartphones and tablets, ensuring uninterrupted usage.
Portability
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.
Since the 56125i weighs only 31.6 lbs, it can be labeled as a portable lightweight generator. Thanks to its lightweight design, one person can easily move it around, ensuring power availability wherever you travel. Its handle (molded in the case) makes carrying it a simple task, further enhancing its convenience.
Good to know: This unit ranks 6th in our list of the 10 smallest portable generators.
Features
Some light indicators allow you to instantly see if the generator is overloaded, its oil levels are insufficient and the generator is ready.
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.
Besides the features previously mentioned, accessory-wise, the WEN 56125i comes with the usual documentation and owner's manual (opens in a new tab) needed to get you promptly started.

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).
- In terms of its dry weight, the WEN 56125i stands at only 31.6 lbs, meaning that is one of the lighter inverters of the 1000-2000 rated wattage category In terms of weight, one of the champions in their power range is the Pulsar PGD16iSCO, standing at just 24 lbs.
- As its lowest possible noise is rated at 51 dBA, this inverter generator qualifies as one of the more quiet of the products of similar type and power. 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.
- Regarding its autonomy, the autonomy of the 56125i, reaching around 5 hours at a 50% load, can be considered as low end, compared to other inverters of a roughly equal output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Westinghouse iGen2200, reaching around 10 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. At an estimated fuel consumption of 0.14 GPH (gallon per hour) at 50% load, this inverter generator is a rather fuel-efficient one within its wattage category. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.09 GPH, the Pulsar PGD16iSCO is a device you could look out for.
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.
