by Charles Jasper

Product Overview

The WEN 56203i super quiet 2000-watt portable inverter generator is one of the best available. It even has a running volume of just 51 decibels. This ultra-quiet generator is amazingly lightweight and tiny while keeping up with all your power demands.

When running at half capacity, the WEN 56203i is quieter than you would expect from a motor this powerful. Its volume is comparable to that of a regular conversation, but it can still generate enough power to run your refrigerator or pop popcorn in your microwave oven.

An Impressive Lack of Harmonic Distortion

Electrical energy travels in the form of sine waves. Ideally, those waves are perfectly clean, or smooth, to keep our electronics running safely. Unfortunately, all inverter generators produce distorted sine waves that have the potential to do damage to your devices. The greater the distortion of the wave, the greater the risk there is to your device.

With the development of the 56202i, WEN took the time to ensure that distortion was limited to just a 1.2% change from perfection. This means that the electrical energy being used to charge your tablet, phone, and laptop won’t do any damage to those valuable devices.

You can plug your favorite electronics into the WEN56203i with the confidence of knowing that the power produced by this ultra-quiet generator is as clean as safe as it can be.
