Power outages in Georgia can last a lot longer than expected, and that’s when the difference between owning a generator and owning the right generator for your home becomes obvious. After 15 years of running backup power through summer storms and extended outages, I’ve learned that the best setup depends just as much on how you want to use it as how many watts it can produce.
For completely hands-off backup, the Generac 14kW Standby is our top choice, starting automatically within seconds and running from natural gas or propane through a 200A transfer switch. The WGen9500DF is the more practical portable option, delivering 9,500 running watts with dual-fuel flexibility and transfer-switch-ready output. If noise, fumes, and fuel storage are concerns, the EcoFlow DELTA Pro offers 3,600Wh of battery capacity and 3,600W output in a silent solar-compatible system.

How I Tested
I test home generators around the way they’re actually used during an outage, not by simply starting them in the driveway and checking whether an outlet has power. With 15 years of hands-on experience around generators and electrical loads, I focus on whether a unit can keep essential equipment running when the grid stays down for hours.
- For portable generators, I run combinations of refrigerators, freezers, lights, fans, and higher-demand appliances while tracking sustained output, starting surge, runtime, fuel use, and noise. I also check cold and warm starts, outlet configuration, transfer-switch compatibility, and how manageable the generator is to move and refuel during a longer outage.
- Standby generators get judged differently. I focus on automatic outage detection, transfer time, sustained household loads, fuel setup, and whether the system can provide genuinely hands-off backup. A standby unit should come online when needed without someone having to go outside and start it manually.
- For battery and solar generators, testing shifts to usable battery capacity, sustained AC output, recharge time, solar input, and how long essential loads can realistically stay powered. I also consider noise, UPS functionality, expandability, and how much maintenance the system eliminates compared with a fuel-burning generator.
Across all three types, the goal stays the same: reliable power under real loads, realistic runtime, and a backup system you can actually depend on when an outage lasts longer than expected.
Quick Guide – Which Type Is Right for You?
There’s no single type of generator that’s right for every outage. How much of your home you want to power, how long outages typically last, and whether you want automatic backup should determine which direction you go.
| Type | Best For | Typical Power | Fuel / Energy | Setup |
|---|---|---|---|---|
| Standby Generator | Whole-home, hands-free backup | 14-22kW+ | Natural gas / propane | Professional installation |
| Portable Dual-Fuel | Emergency backup & flexibility | 9,500-13,000W | Gas + propane | Portable / transfer switch optional |
| Battery Solar | Quiet backup & essential loads | 1,800-4,500W+ | Battery + solar / AC | Plug-and-play |
Standby generators are the set-it-and-forget-it option, while portable generators give you more power per dollar if you don’t mind setup and refueling. Battery systems are the quietest and easiest to use, but runtime ultimately depends on battery capacity and what you’re powering.
If your goal is simply to keep the fridge, freezer, lights, internet, and a few essentials running, you may not need a full standby system at all.
Other Home Generators We Have Tested
If a permanently installed standby generator feels like more than you need, there are plenty of portable alternatives that cost less upfront and don’t require a permanent installation. These three stood out for different reasons, from lightweight battery backup to serious whole-home emergency power.
- EcoFlow DELTA 2 (Best Compact + Fast Charging): At just 27 lbs, the DELTA 2 is much easier to move around than a fuel generator. Its 1,024Wh LiFePO4 battery delivers 1,800W through 15 outlets, recharges fully in about 80 minutes, and can expand to 3kWh. A practical choice for keeping essential appliances and electronics going quietly.
- Champion 11,500-Watt Dual Fuel (Best Budget Dual-Fuel Portable): Running on gas or propane with electric start and a wheel kit for easier moving, this is the one I’d look at if the Westinghouse picks above feel like more generator than you need. It delivers 9,200 running watts and comes with a 3-year warranty.
- Jackery Explorer 2000 v2 (Best Mid-Size Battery Backup): A step down in capacity from the EcoFlow DELTA Pro above, this 2042Wh LiFePO4 unit delivers 2200W of AC output and fast-charges over USB-C, worth a look if 3,600Wh feels like more battery than your household needs.
The advantage of these models is flexibility. You can move them where they’re needed, avoid the higher installation cost of a permanent standby system, and still get meaningful home backup power. The trade-off is that portable generators require more hands-on setup, and fuel-burning models must always be operated outdoors in a safe location.
How Much Generator Power Does Your Home Actually Need?
You don’t need enough generator power to run every appliance in your house at once. During an outage, the smarter approach is to decide what absolutely needs to stay on, add up those loads, and leave enough headroom for appliances with high startup demands.
| Generator Size | What It Can Typically Cover | Best For |
|---|---|---|
| 2,000 – 4,000W | Fridge, lights, Wi-Fi, TV, electronics | Basic essentials |
| 5,000 – 8,000W | Essentials + freezer, sump pump, some small AC loads | Typical outage backup |
| 9,000 – 13,000W | Multiple appliances, larger AC loads, pumps | Heavy home backup |
| 14 – 22kW+ | Most or all household circuits | Whole-home standby |
Don’t Forget Starting Watts
A refrigerator might only draw a few hundred watts once it’s running, but its compressor can demand considerably more power for a few seconds at startup. The same applies to freezers, pumps, air conditioners, and other motor-driven appliances.
That’s why I don’t recommend sizing a generator right at the total running wattage of your appliances. Leave some headroom for startup surges and changing loads.
Start With the Essentials
For most outages, I would calculate the refrigerator, freezer, lights, internet equipment, medical or other essential devices, and heating/cooling needs first. Then add convenience loads only if there’s capacity left.
A 10,000W portable generator can make sense for one home, while another household may be perfectly comfortable with a much smaller battery system. Buy for the loads you actually need to keep alive, not the biggest wattage number on the box.

FAQs
1. How many hours will a generator for power outages run a fridge?
A mid-size refrigerator draws about 600 watts when the compressor kicks on. Most portable generators in this list will run one for 8 to 12 hours on a full tank of gas, depending on the rated running watts and fuel capacity. Propane models often run longer on the same physical tank size because propane has more energy density than gasoline. Power stations are measured in watt-hours, so a 1000Wh unit will give you roughly 1.5 to 2 hours of fridge runtime before needing a recharge.
2. Can I use a generator indoors or in my garage?
No. Gas and propane generators produce carbon monoxide, which kills in minutes in enclosed spaces. Run them outside, at least 20 feet away from windows, doors, and air intakes. Power stations with batteries are safe indoors because they produce no fumes. If you need backup power inside your home, a battery-based power station or a hardwired standby generator with proper venting is your only option.
3. What is the difference between surge watts and running watts?
Surge watts (peak watts) are the maximum power a generator can deliver for a few seconds when a motor starts. Running watts are what it can sustain continuously. A fridge might have 600 watts running but 2000 watts surge when the compressor kicks on. You need a generator with enough surge capacity to handle the startup, but the running watts determine how many appliances you can power at the same time. Always size based on running watts for appliances you plan to run together.
4. How long does a portable power station battery last?
Most modern power stations use LiFePO4 chemistry, which is rated for 3000 to 4000 charge cycles before dropping to 80% capacity. That translates to 8 to 11 years of daily use, or much longer if you charge it a few times a month. NMC batteries are cheaper but degrade faster. I have run the same LiFePO4 power station for five years with no noticeable loss, so the ratings are conservative if you avoid deep discharges and extreme temperatures.
5. How fast can a power station recharge from solar?
Real-world solar input depends on sun angle, weather, and panel quality. A 100W panel in full midday sun will deliver roughly 80 to 90 watts of actual charging power to a power station. That means a 1000Wh unit takes about 11 to 12 hours to charge fully in good conditions. Cloudy days cut that in half or more. The rated solar input on the spec sheet assumes ideal lab conditions, so expect slower recharge times in real use. Wall charging is always faster if you have access to power.
6. What size generator for power outages do I need for my home?
It depends on what you want to run. If you are powering a fridge, lights, and a sump pump, a 9500 to 12500 watt generator will do it. If you want to run AC along with those, you need 15000 watts or more. For power stations, a 1000Wh unit handles phones, laptops, and lights for a day. For a fridge overnight, you need 2000Wh minimum. Do a real load audit: write down the running watts of everything you want to run at once, add them up, and pick a unit that exceeds that total by at least 20 percent.
7. How do I connect a generator to my home with a transfer switch?
A transfer switch is a safety device that prevents backfeed into the grid and protects utility workers. Most generators in this list have a 30A or 50A outlet designed for portable transfer switches, which you plug into the generator, then run a heavy-duty cord into your home to a manual transfer switch installed by an electrician. Never run a generator cord through a window or door without a proper transfer switch in between. Hire a licensed electrician for the install to avoid code violations and electrocution risk.
