Best Portable Generator for Emergency Backup Power
Honda Super Quiet Series Generator EU7000iS
Portable generators are popular emergency backup power options thanks to their lower cost, the portability to use them for other activities, and the ability to store them out of the way. The downside is that most portable models canโt power your whole house, so you have to pick and choose what to keep running and what to do without.
I like the 5000-watt class for its balance of portability and power, and that itโs possible to get one with a quiet operation design. Hondaโs EU7000iS is the one I recommend. Thereโs a host of features built into it, but itโs the outstanding reliability of the GX390 EFI engine that seals the deal. Hondaโs commercial engine reputation is stellar, and I trust the GX series to last longer than any other small engine available on portable generators today.
Pros
- Electric start
- Electronic fuel injection
- Quiet operation

Best Home Generator for the Money
Westinghouse WGEN7500
For those of you who want the most watts for the buck, there are several good options. Ryobi and Generac both have solid choices at the $900 price point with 6500 continuous watts and CO detection. However, you can get a bit more for your money with the Westinghouse WGEN7500. At 7500 continuous watts, it offers higher power delivery, as well as electric and remote starting.
There are trade-offs, though. Compared to the Generac and Ryobi models, you donโt get the CO detection. More importantly from a comfort standpoint, you have to give up having a quiet generator, though this one does have more power than our Honda EU000iS offers.
Pros
- More power than other brands at the same price point
- Electric and remote start
- 120V and 240V outlets
- Carbon monoxide detection with automatic shutoff
- CARB-compliant
Cons
- Standard loud operation
- Not rated for sensitive electronics
Key Decision Factors
| Power Range | 7500W Continuous/9500W Surge |
| Engine | 420cc 4-Stroke OHV Westinghouse |
| Starting | Electric and Pull |

Best Budget Home Generator Under $500
Champion 100522
If youโre looking for a quality generator under $500, itโs a tougher task than it was a few years ago. There are a lot of brands at this lower price point that we havenโt tested, so we canโt give them a recommendation one way or the other. After filtering through whatโs left, I like the Champion 100522. It offers 3500 continuous watts with an outlet package thatโs RV-ready at a price thatโs $100 under budget.
As we expect for a budget pick, it doesnโt have as much power or as many features as more expensive models. If you want to upgrade, you can get electric and remote starting for $100 more. The big thing to keep in mind is that youโll have to manage your power use and keep an eye on refilling the smaller fuel tank when youโre running on the upper end of the continuous watt limits.
On the plus side, this is a smaller generator thatโs easier to move around when you need it.
Pros
- Affordable
- Lighter and smaller than higher-powered generators
- Low-oil shut-off protects the engine
- RV-ready
- CARB-compliant
Cons
- Standard loud operation
- Limited on how many things it can power at once during an outage
- Not rated for sensitive electronics
- No 240V outlets
Key Decision Factors
| Power Range | 3500W Continuous/4375W Surge |
| Engine | 208cc Champion single-cylinder OHV |
| Starting | Pull |

Best Propane/Natural Portable Gas Generator for Home Emergency Backup Power
Champion 201169
Even when youโre on the hunt for a generator that uses natural gas or propane, I still prefer having the gasoline option of a tri-fuel model. Three primary brands in that space are readily available: Champion, DuroMax, and Westinghouse. Thereโs a nice range of power options available, including models from each brand that hit either 12,000 or 13,000 continuous running watts.
You need to balance your power desire with your ability to move the machine, though. My preference is to settle in the middle range with Championโs 201169. With 6500 running watts, it has the power to offer a 240V plug when you need one while maintaining good portability. This model includes CO detection along with electric starting as a nice bonus. You even get the LP and natural gas hoses you need in the box.
The downside is that itโs more expensive than gas-only generators in the same power range, but thatโs normal for any of the competitors in this space. It also misses out on quiet operation and has an OEM engine.
Pros
- Use gas, liquid propane, or natural gas for fuel
- Electric start
- 120V and 240V outlets
- Carbon monoxide detection with automatic shutoff
- Low-oil shut-off protects the engine
- Includes hoses for LP and natural gas
Cons
- Standard loud operation
- Power level and runtime vary based on which fuel youโre using
- More expensive than gas-only models at the same power level
- Not rated for sensitive electronics
- Not CARB-compliant
Key Decision Factors

| Weight | 197 pounds |
| Price | $1129 |
Best Solar Generator for Emergency Backup Power
Solar generators fall into two broad categories: those that are truly portable and those that are designed to stay in your home. In the uncertainty of a power outage, I like having the ability to swap batteries out since solar recharging is a longer process thatโs directly affected by how much sunlight you have available. I also like being able to take my solar generator on the go and use it for outdoor recreation.
However, the latest generation of integrated battery models includes expandable battery systems that can lead to both higher power output and greater total capacity than swappable systems. In terms of emergency power for your home, these systems are superior.
There are several trade-offs you need to consider, though. Neither design offers as much wattage as a portable or whole home generator can produce, so choose your battles on what youโre going to power. As you expand your capacity on integrated battery home systems, the storage space thatโs required becomes significant and the cost is considerable, especially when you add the cost of permanent solar panels attached to your roof.
With that introduction out of the way, I have a recommendation for you in each category.
Best Portable Solar Generator: EGO Nexus Power Station PST3041
EGOโs Nexus Power Station is compelling on several levels. It has a highly detailed LCD screen that shows you tons of useful information. Even though it tops out at just 1800 continuous watts, itโs the battery platform that sets it apart. Running 56 volts, its highest capacity battery is 12 Ah, totaling more than 600Wh of capacity. With four of those bad boys on board, youโve got more than 2400Wh to work with.
The proposition is even greater if youโre already on the EGO battery system for your lawn care needs. If you happen to have the 54-inch zero-turn mower that came with 12Ah batteries, itโs icing on the cake.
Even if your EGO collection includes 6.0Ah, 7.5Ah, or 10Ah batteries, itโs still a highly capable system that has plenty of potential at home and on the go.
Pros
- Powers on with the push of a button
- Near-silent operation
- Produces clean sine wave energy that wonโt damage electronics
- LCD screen with helpful information, including remaining runtime estimate
- No maintenance, emissions, or fuel to manage
- Solar or AC recharging
- Swappable batteries
- Safe to run indoors
- Includes USB charging ports
- High-capacity batteries maximize runtime
- higher surge rating than 2000W gas generators
- Runs on the same batteries that power EGO lawn care products
- Easy to transport for other uses
- Bluetooth connection to the EGO Power+ app
Cons
- Available power drops with fewer batteries (based on combined battery capacity)
- Limited power reduces what you can run during an outage
Key Decision Factors

| Fuel | EGO 56V Batteries |
| Fuel Capacity | 4 x 12Ah batteries |
| Runtime | Variable |
| Weight | 36.71 lbs |
| Price | $1499 kit |
Best Integrated Battery Solar Generator: EcoFlow Delta Pro Ultra EFDPUPCS-BP
Remember when I said solar generators donโt offer the same power as whole-home generators? That statement still stands when it comes to the maximum power they offer, but EcoFlow gets well into that power range.
Each EcoFlow Delta Pro Ultra base unit can produce up to 7.2Kw of energy, and you can parallel three of them together to hit 21.6Kw. Additionally, you can expand with as many as 15 additional batteries to reach a total of 90kWh of energy storage. According to estimates, the average American home uses 30kWh per day, meaning EcoFlow has the potential of three daysโ worth of whole-home no-compromise power.
For solar recharging, it can handle up to 16.8kW of panel input. With panels rated at that mark, the 60% โ80% efficiency we see in Florida would give you a full 90kWh recharge in 6 1/2 โย 9 hours of optimal sun (assuming youโre not drawing power while recharging).
So whatโs the cost of such a convenient emergency power system? Each Delta Pro Ultra base inverter is $5799, and each battery is $3299. For a full 90kWh system, youโre looking at just under $67,000. Also, keep in mind the cost of solar panels and installation into your home power system.
Pros
- Potential for off-grid power when combined with solar panels
- High available battery capacityโenough to run several days with normal power use or weeks with managed use
- Capable of producing mid-range whole-home generator power

Home Generator Safety Tips
Generators make our lives easier, but they can be deadly. Never, ever run a gas, propane, or diesel generator inside! They produce emissions that will kill you if they can concentrate high enough.
Always make sure that youโre running your generator where thereโs plenty of airflow. Opening a window or your garage door isnโt enough. Air has to be able to let the fumes dissipate and move away from your generator so they donโt concentrate in one area.
Many portable generators now come with a CO sensor that automatically shuts the engine off if fumes get too high. They can shut down when thereโs no immediate danger, though. Make sure you position your generator so the breeze can blow past the exhaust rather than concentrating on the downwind side.
Here are some other safety tips:
- Be careful of hot engine components
- Always use the right gauge extension cord for what youโre powering
- Donโt overload your generator
- Donโt store fuel near ignition sources (including your generator)
- Protect your generator from rain and snow
More Home Generators You Should Consider for Emergency Backup Power
Generac GP18000 EFI
If you want the most power, you can get out of a portable generator, Generac has an 18,000-watt model thatโs the best weโve seen. In fact, PTR Editor-in-Chief Clint DeBoer specifically got this for his home as an alternative to a permanent install whole-home generator. While this model produces a ton of power, itโs heavy and thirsty. Donโt skip the gym and be sure to have plenty of fuel on hand when the power goes out.
Key Decision Factors
| Power Range | 18000W Continuous/22500W Surge |
| Engine | 816cc Generac |
| Starting | Electric/Pull |
| Fuel | Gas |
| Fuel Capacity | 14.2 gallons |

Ryobi 18V One+ Power Station RYi1000VNM
Ryobi developed three similar portable inverters and bracketed the needs of everyoneโeven if youโre not on one of their battery systems. Thereโs a model for 18V One+ users, one for 40V users, and one with an integrated battery if that suits your needs better.
With millions of people on the 18V One+ platform and more than 300 products that work on the same battery, itโs the 18V model we expect to be the most popular of the three. While youโll go through your batteries more quickly than ones on the higher capacity 40V system, theyโre easily swappable. Plus, this is a highly portable unit that you can take on the go as well as have on hand for emergency power.
| Power Range | 1800W Continuous/3000W Surge |
| Power Source | Battery |
| Starting | Push Button |

Greenworks PowerHub 8201502
Greenworks is moving deeper into the potential of battery power, and that includes energy storage for your home. Rather than relying on a portable inverter, the PowerHub system is specifically designed as a permanent installation, so you donโt have to worry about rolling things out when the power goes out.
The max power output is lower than parallel-capable systems but among the highest for the single inverter. With pre-configured 10kWh and 20kWh systems ready to go, it takes some of the guesswork out of creating your system. Plus, you can expand with up to four PowerHubs to get a total of 80kWh of capacity. What you wonโt see from other brands is that Greenworks backs the PowerHub with a 12-year warranty.

Choosing the Best Generator for Home Backup Power
Power Needs
Having enough power is goal #1 for us. You need to plan for not just the running load, but the surge power that each of the items youโre running needs.
What size generator do you need? That depends on what devices you plan to power. With some simple math and planning, you can arrive at easy guidelines for making a solid choice.
Reliability
Most generators you buy from quality brands and reputable retailers are just fine as long as you take care of your generator maintenance. Even brands with an OEM-branded engine have the potential to offer you years of service if youโre using them often.
As youโre shopping for the best generator for home use, keep in mind that many people only use them in an emergency. That means they need to reliably start and run even if they sit in your garage unused 98% of the year.
If that sounds like you, one of the best things you can do is pull the generator out and start it once a month. Always use a fuel stabilizer and try to run the tank dry when you know youโre not going to use it for a while.
Price and Value
Buy the best generator for your home that fits your budget. In our opinion, getting better quality over higher watts is the way to go if it comes down to a choice. Ask yourself what features you really need and be willing to forgo some of them to get a better price on a unit with a high-quality engine.
Noise Level
If youโre going to use your home generator for camping, RVing, tailgating, or other outdoor activities, you may want to go with a quiet model. These are usually in the sub-3000-watt class, but weโre beginning to see more powerful models promising quiet operation.
Features to Look For
- Bluetooth connection: monitor fuel levels, shut the generator off, and view other diagnostic information from your phone
- Electric start: keep the battery charged and eliminate pull-starting
- Electronic Fuel Injection (EFI): better starting and efficiency with fewer maintenance issues
- 240V plugs: if you want to run higher-demand items
- Total Harmonic Disruption (THD): how โcleanโ the power is for running electronics
- Carbon monoxide sensor: shuts the engine off if CO concentrations get too high
- Fuel capacity: the larger the tank, the longer between refills
- Portability: how you transport the generator from storage to where youโre going to use it
