In reply to Roberto Guerra. I wouldn't recommend using any electrical equipment/device during a brownout. The decreased voltage can cause excess heat that can damage or shorten the life of your device.

Will a 120 volt fan be damaged if operated during a brown out?

There are several devices on the market called “Solar Generators” which is actually a misnomer. A better description would be “Battery Backup” or “Power Converter” as with the Jackery products. I say this because they don’t actually “generate” anything. Rather, they convert power from the grid (when recharging) or from a solar panel to chemical energy stored in a battery bank. The battery then supplies energy to an Inverter that converts DC to AC and delivers 110 volts AC to standard outlets on the front of the device. However, there is a built-in problem where these units are designed to deliver 110 volts as opposed to the standard in the U.S. of 120 volts. In other words, they operate at brownout levels. When the consumer uses one of these devices in conjunction with an extension cord, smaller wire gauges within the cord introduce a voltage drop (depending on cord length) that exacerbates the low voltage problem. And of course, anyone who understands Ohm’s Law knows the appliance will draw more current and produce more waste heat when operated at lower than standard voltage. The only exception I’m aware of would be computer power supplies (such as those found in tower computers) that are designed with a wide input range of voltages. So, they will work on any system be it Europe with 220 or Japan with 100 or US with 120. I would venture to say most consumers have no clue their “Solar Generators” operate at sub-standard voltage right out of the box.

Hello.This post was extremely remarkable, particularly since I was investigating for thoughts on this matter last Wednesday.
