How To Choose An Inverter Power Generator

Portable power stations play a very important role in supplying energy that can be used to power indoor and outdoor electrical appliances. 

However, careful considerations should be made to decide what particular make and model would be suitable for you. Some of those factors that should be considered include:

Power Output Rating

A power output rating is an indication of how much power the generator can supply at a given point in time. This is one of the factors, if not the most important factor to consider. Make sure that the indicated power output rating is enough to cater to your energy needs. Of course, this has to do with your energy usage and reason for purchase.


The cost of acquiring this device is yet another factor to consider. It’s a good thing that there are many power stations of different price ranges available in the market. So if you have enough to spend, you can go for anyone, otherwise, stick with the low-cost models.

Also, bear in mind that other than the initial cost, you might still have to spend on maintenance and accessories.


Noisy generators can be very annoying. They pollute the whole place with their loud sound making the environment uncomfortable for us. Annoying noise from a generator isn’t one of the things you need while on a fun trip with friends. If you are to enjoy your portable power station to the fullest, go for the less noisy ones.

The Rainier R2200i Review

This product serves as a perfect companion for when you are on the go. It is very much reliable and supplies you with constant power, especially when you’re in remote places. It’s ideal for locations like campsites, hiking routes, fishing sites, or even mountain tops.

Features of The Rainier R2200i

Double Up

One of the peculiar features of the Ranier r2200i is its ability to integrate with other generators. Power generation is doubled because of the parallel connection between two inverters. This way, you will be able to charge more appliances for a longer period of time.

Engage ‘Eco Mode’

This feature helps conserve fuel in the system. Once you push the button to activate ” Eco mode”, the machine will spontaneously reduce its idle speed. This reduced speed is required to augment the amount of current needed by the load to increase fuel efficiency. This helps to avoid fuel wastage and reduce friction in moving parts.

Super Quiet

The R2200i ensures the serenity of the environment by operating at a sound as low as 52dBA. It isn’t as loud as other regular portable power stations like WEN 56202i. Therefore, they can be conveniently used in areas that are sensitive to sound. Such places include neighborhoods, parks, and campsites.
