Buying Guide: How to Choose a Battery Powered Generator for Home Backup
When my power went out last winter, I realized I needed a reliable backup source. I started looking into battery powered generators, and let me tell you, the options can be overwhelming. After a lot of research, I figured out what really matters. The first thing you need to get your head around is wattage. Think of it in two parts: running watts and surge watts. Running watts are what an appliance needs to, well, run. Surge watts are that extra burst needed to start up motors in things like refrigerators or furnace fans. Make a list of the essentials you want to power—like your fridge, a few lights, your phone charger, and maybe a router—and add up their running watts. Then, check which one has the highest surge watt requirement. Your battery generator needs to handle both numbers.
Next up is battery capacity, which is usually measured in watt-hours (Wh). This is like the size of your gas tank; it tells you how long the unit can run. A 500Wh battery can theoretically power a 500-watt device for one hour, or a 50-watt device for ten hours. For basic home backup during a short outage, something in the 1,000 to 2,000Wh range is a good starting point. If you want to run bigger appliances or have power for a full day or more, you’ll be looking at much larger capacities.
Don’t forget about the outlets! Check what types of ports the unit has. You’ll want a mix of standard 120V AC outlets (the ones you have in your wall), USB-A and USB-C ports for phones and laptops, and maybe even a 12V car outlet. Also, pay close attention to recharge times. How long does it take to fill the battery back up from a wall outlet? Can it recharge from a car charger or, even better, from solar panels? Solar compatibility is a huge plus if you’re thinking about long-term outages or off-grid use. Finally, consider the physical stuff: size, weight, and where you’ll store it. Some of these units are compact, while others are heavy and need a permanent spot. By focusing on these key areas—wattage, capacity, outlets, and recharge options—you can find the best battery powered generator for your home backup power needs without getting lost in the specs.
Frequently Asked Questions
How long can a battery powered generator run my refrigerator?
This is probably the most common question I had when I started looking. The answer isn’t simple because it depends on your fridge’s specific energy use and the size of the generator. A modern, energy-efficient refrigerator might use between 100 and 400 watts when its compressor is running. However, the compressor cycles on and off. To get a rough estimate, you’d need to check your fridge’s manual for its yearly kilowatt-hour (kWh) usage and do some math, or better yet, use a watt meter. As a general example, a 1000Wh battery generator could potentially run a fridge that averages 150 watts for about 6-7 hours, but this can vary widely based on how often you open the door and the ambient temperature.
Can I use one of these to power my entire house?
Most standalone battery powered generators are not designed to power an entire house simultaneously. They are fantastic for running a collection of essential devices—what we call a “circuit” of critical loads—like your fridge, lights, communication devices, and a fan. To back up your entire home’s electrical panel, you would typically need a much larger, permanently installed system that is wired directly into your home’s electrical system by a qualified electrician. For most of us, selecting the right appliances to keep going during an outage is the more practical and affordable approach.
Are they safe to use indoors?
Yes, this is one of their biggest advantages over traditional gas generators. Since they have no emissions and produce no fumes, they are perfectly safe to operate inside your home or garage. You don’t have to worry about carbon monoxide poisoning. This makes them incredibly convenient, as you can keep them running right in your living room to power lamps and charge phones without any safety concerns.
What is the difference between a power station and a portable power bank?
This is a great question that clarifies the product category. A portable power bank is a small device, often pocket-sized, meant for charging phones, earbuds, or maybe a small tablet a few times. A battery power station, which is what we’re talking about for home backup, is in a completely different league. It’s larger, heavier, and has a much higher capacity and output. It features standard AC outlets to power household appliances, multiple USB ports, and other outputs, making it a viable source of backup power for your essential home needs during an outage.
How do I maintain my battery powered generator?
Maintenance is thankfully very low compared to a gas engine. The key is to take care of the battery. For long-term health, it’s best not to store the unit fully charged or completely drained for extended periods. If you know you won’t be using it for a while, charge it to around 50-80% and store it in a cool, dry place. It’s also a good practice to use it and recharge it at least once every three to six months to keep the battery chemistry active. Other than that, just keep it clean and avoid physical impacts.
