Everything You Need to Know About Buying a Backup Battery Power Generator

If you’re looking for a backup battery power generator, you’re already working in the right direction of creating a safe and secure environment for your family to face any type of emergency situation. You probably already know the benefits of having a backup power supply, but do you know the best qualities you should be looking for when deciding which brand to purchase? 

Whether you want to be able to power your refrigerator during a power outage or charge your cell phone on a camping trip, here is a breakdown of five of the most important features to look for when purchasing a power supply.

What Is a Backup Battery Power Generator

A backup battery power generator is a compact, portable power generator that can supply your home with electricity during a power outage or emergency situation. Power generators store electricity in its battery that can power the household appliances and devices of your choosing.

Pay Attention to Safety & Reliability Features

If you’re purchasing a backup power generator to keep your family safe during an emergency, you need to feel safe actually bringing the product into your home. You don’t want to have to worry about the product overheating or causing a power surge. Research what safety features are embedded in the product and which safety tests are performed prior to sale. 

The battery management system should have built-in modules that prevent the generator from device-damaging events like over-surging and short-circuiting. This type of built-in protection will ensure your devices will be safe from damage and that the unit will not overwork itself and break down. You also should never buy a unit that has not been tested and approved by the U.S. Department of Energy. Other safety tests that will certify the product’s safety and reliability are conducted by the California Energy Commission and Federal Communications Commission. If you plan to travel with your generator, it will need to be certified by the United Nations 38.3 Transport Safety Standard.

To be prepared before an emergency strikes, you’ll have to proactively purchase products. This means you could have the product sitting around for quite some time before you actually use it. You’ll want to ensure that the brand you choose has a prolonged warranty so that it doesn’t expire before you actually get a chance to use the product. On the other hand, if you experience frequent power outages, you’ll need a warranty that can accompany prolonged use of the product, in the event of an unexpected malfunction down the road. Most warranties expire within two years after purchase, but we advise against purchasing any device that comes with less than a 5-year warranty. This will give you ample time to live with your generator and feel confident that the company backs the reliability of their product!

Check for Compatible Devices

When the power goes out, you’re already extremely limited with what you are able to do without electricity. Adding a backup battery supply should alleviate some of the stress that comes with a power outage, by helping you charge up and power a wide variety of home devices and household appliances. Think about which devices you’d most want to power during a blackout and find a power station that is compatible with them all. Some common outputs that you will most likely benefit from having on your backup generator will be USB style ports for charging cell phones and tablets, as well as DC and AC outlets for larger appliances in your home.

Check Wattage Requirements 

If you want to be able to power heavy-duty appliances, like the refrigerator, you need to ensure that your generator has the output bandwidth to allow for this. Research what each product’s output capabilities are and what output is required for the devices you wish to power. Be sure these properly align before making any purchasing decisions. For the smoothest experience, the outlets should emit Pure Sine Wave at 110V and 60Htz. Larger appliances will require 1000W and protected surge power of 2000W.

Calculate Usage Time

A power outage can be extremely unpredictable, and it can take hours or days for it to be turned back on. That will require you to get a lot of usage out of your backup generator. You’ll want to find one that is not only widely compatible, but one that can also last for an extended period of time without needing to be charged again. When the backup battery is fully charged, different devices will drain its battery at different paces, but we recommend purchasing one that can run for up to seven days with being recharged. 

Look for Easy & Efficient Recharging Capabilities 

Some power stations expect you to recharge from an electrical outlet, which if you’re facing a power outage, impedes the purpose of having the generator. Pay attention to the ways your power station is able to be recharged, and how long it would take. Never purchase a backup battery that can only be charged one way, as you may not have access to that form of charging in all emergencies. Other means of charging are from a solar generator or car outlet. Investigate how efficiently your backup battery can be recharged to be the most prepared -- will it take a few hours or a full day of charging? Additionally, it will be most beneficial to purchase a backup battery that can simultaneously be used to power devices while being recharged, so you have a seamless experience during an outage.
