See the FAQ below for key differences. The top portable power stations, also often called portable power generators, fall into two broad categories based on the method they use to collect and store energy: electric and solar. Many times, solar portable power stations are also rechargeable via AC power, serving as a rechargeable generator of sorts.
Just the names – neither a portable power station nor a solar generator create energy on their own, they just store it so you can use it anytime. The same goes for battery-powered generators. The “solar” element just indicates that generators can connect to solar panels but so can some portable power stations.
Though the battery is the main part of a portable power station, there are also a number of components and technologies that send stored energy safely and efficiently to your appliances. They have tech that makes them recharge faster, screens that show input and output, and even apps for remote energy management.
Many times, solar portable power stations are also rechargeable via AC power, serving as a rechargeable generator of sorts. Electric power stations, also known as portable electric generators, operate like a large battery. Simply plug the portable power station into a wall outlet and it charges quickly.
Some portable power station models can also be used as an uninterruptible power supply. In this mode, you'd keep your electronics plugged all the time with the portable power station providing pass-through power, and the battery switches over in the event of a power outage, keeping your electronics running without a blip.
Outside of gas-powered home generators, two of the most popular options are portable power stations and uninterruptible power supplies (commonly known as a UPS). Both are large batteries at their core, but they have different capabilities. A portable power supply might pack more power, but that comes at a price.
