Standby generators are the gold standard of home backup power thanks to their high output, no need for refilling (unless you get a diesel unit, in which case it just requires far fewer refills), automatic kick-on, and more. Like anything else, though, there are pros and cons to consider that may make a standby generator the wrong option for some buyers, especially those looking to maximize value on a smaller budget.
In this quick guide, we’ll cover the pros and cons of standby generators and compare them to other common generator options that offer different benefits and drawbacks. By the end, you’ll know exactly what the right backup power option for your home is.
Standby Generator Pros and Cons
Standby generators are known for being the best option for those seeking the maximum reliable backup power possible for their home. One of the only options for true whole-home backup power, these generators are installed permanently on a property and cannot be moved. This makes them great for the sole purpose of providing backup power for your home, but not great for any mobile use cases like more versatile portable generators.
Standby Generator Pros and Cons
| Pros | Cons |
| ✔ High power output (most/whole home) ✔ No refilling required (or fewer for diesel) ✔ Automatic start-up | ✘ High cost ✘ Not portable ✘ Permanent installation |
The other major consideration when comparing standby generators to other generators is their cost. Standby generators are the most expensive option available, mostly due to the fact that they can also produce far more power, and can use a variety of different fuel sources including your home’s own natural gas line to avoid the need to refill.
Alternative Option: Portable Generators
Another popular choice among homeowners are portable gas generators. These generators are less expensive and smaller, and they put out less power, but they are easy to move around or load onto a truck/SUV/camper to be used for mobile purposes like camping, construction, and more. This makes them a great choice for homeowners who want to spend less money and/or use their generator for other things.
Portable Generator Pros and Cons
| Pros | Cons |
| ✔ Affordable entry price ✔ Portability allows for more versatility ✔ Multiple units can be connected for higher power output | ✘ Can’t run an entire home ✘ Require manual start-up ✘ Require periodic refilling, especially when used for home backup power |
If you’re on a tight budget and okay with an option that will only run a couple of key rooms in your house in an emergency, portable generators could work well enough for you. If you’re a camper, hobbyist, or contractor who values being able to use the generator for other projects, it is likely an even better overall option for your needs than a standby generator. Just know that if you do lose power, you’ll need to manually turn on the generator and refill it from time to time to keep the lights on.
