The Best Portable Generators of 2023

When you’re in a lurch with no electricity for your home or camp, having a portable generator to get things running is a godsend. These powerful machines are lifesavers after storms knock off electricity, or if you need a boost to run equipment. Ever been at your hunting or fishing camp and need to do some work? Without power, you’re out of luck for running saws, tools, and appliances. With a good portable generator, though, you’ll be able to run tools, refrigerators, and other equipment for as long as you have fuel.

• Best Overall: Generac 5735 GP17500E
• Best for Home Use: Westinghouse WGen7500
• Best Inverter Generator: Honda EU7000is
• Best Solar Generator: Jackery Solar Generator 1000 Pro

A portable generator is an engine running on gas or diesel fuel that creates temporary electrical power. The engine turns a small internal alternator that creates electricity. You can use a portable generator to run large items, such as a refrigerator, furnace or freezer, or smaller ones such as a microwave or television. Giant generators are used in large buildings for backup electricity; these are larger versions of the portable ones used by homeowners and outdoors enthusiasts. The best portable generators, and fuel to run them, often are in demand after natural disasters.

Best Inverter Generator: Honda EU7000is

Key Features

• 5,500 running watts (7,000 surge watts)
• 263 pounds

Pros

• Extremely reliable and well-built
• Quiet and efficient gas-powered engine
• Compatible with Honda’s My Generator app
• Best for home backup and RV camping

Cons 

• Expensive, even for its size
• Heavy

When you need to fire up your generator, the only thing worse than it failing to start is finding out that it can’t produce adequate power. With the Honda EU7000is, you should never have to worry about either of those problems. Honda’s small engines are just as reliable as the brand’s cars, and this home backup generator is strong enough to power multiple appliances or your RV. 

The 389cc engine generates 5,500 running watts and 7,000 surge watts. Using fuel injection instead of a carburetor, it can run for 16 hours on the 5.1-gallon tank at a 25 percent load. You’ll be able to power things like a full-size refrigerator, a gas- or oil-burning furnace (yep, those still need electricity), and lights. The EU7000is has wheels, but you’ll still want to keep it on paved surfaces because it weighs 263 pounds.

Aside from the workout of rolling this generator out of the garage and into the driveway, Honda made it very user-friendly. You can start it with the push of a button, control it with an app, and monitor its fuel level with a gauge instead of opening the tank every time. Safety features like circuit breakers, GFCI outlets, automatic carbon monoxide shutoff, and warning lights take the stress out of using this generator.

The EU7000is is a significant investment even before wiring your house for it, and it’s even more expensive than a lot of comparably sized inverter generators. But it’s also built to an incredibly high standard and comes with a bunch of features that make it easy to use. In the long run, you’ll be glad you spent a little extra. If you really want to set yourself up right, buy this for your home or RV and something small like the Jackery Explorer 300 for life on the go.

Best Solar Generator: Jackery Solar Generator 1000 Pro (Explorer 1000 Pro + Solar Saga 200W)

Key Features

• Power Station Capacity: 1002 watt-hours
• Solar Panels: Four 200-watt solar panels
• 184 watts generated by one panel in direct sunlight
• Max AC Output: 120 volts and 1000 watts
• Also available with a 2000Wh power station 
• Also available with two 80-watt panels

Pros

• Powerful solar panel
• Easy to use

Cons

• Smaller power station than other models I tested

The Power Station

Along with the BioLite BaseCharge 1500 and Anker 555, the Jackery Explorer 1000 Pro had one of the more streamlined user interfaces of anything I’ve tested. There are separate buttons to activate the USB outlets, AC outlets, and DC outlet, along with a button to turn on the power station’s light (in case you want to light up your camp or home) and one to turn on the display. The display here gives you the bare minimum of information—watts in, watts out, percent of the battery remaining, and the time to charge or deplete the battery based on the current conditions. 

The Explorer 1000 Pro has an output of 1000 watts (2000 watt peak), which is enough juice to power many modern refrigerators. But given that its battery life is only 1002 watt-hours, it can only supply that power for about a day (assuming it’s not charging anything else) unless it’s also being supplied with fresh juice from a solar panel setup at the same time. For some, this won’t be an issue, as they’ll simply be using the battery to channel power to their other devices during the day while it’s charging, and then using the battery at night to power more low-key items like the best camping fans or maybe one high-energy device like a portable fridge. 

At over 25 pounds, the Jackery Explorer 1000 Pro, is one of the more transportable units I looked at, but it’s still not something that you’d want to lug more than a hundred feet or so at a time. It’s proven to be very capable at holding a charge long-term, even after months of sitting in an unheated garage.

The Solar Panel 

I originally tested the SolarSaga 200W solar panel as a full setup, with four panels plugged into a single power station. This test showed the full power of the array, which registered 650 watts of power generation on a sunny (albeit hazy) day. I retested a single panel in tandem with the rest of the units in this review more recently, and under completely clear skies, the panel was even more impressive: It registered 184 watts of energy coming from a single panel. If you don’t have much time to recharge your power station from the sun, then the full setup with all four panels is a no-brainer. (More recent testing of newer panels showed a slight drop in power; however, it is unclear if this is because of natural variation or drop in the product’s efficiency. Either way, this is still a best-in-class panel.)

It is, though, a little complicated. Each panel comes with a carrying case and a cable that connects back to the two DC ports on the Explorer 1000 Pro. If you see a math problem here, that’s correct: You’ll also need two of the Jackery Solar Panel Connectors, which, strangely, are not included in the purchase price. Two of these can be used to double the number of panels you can connect to the Explorer 1000 Pro. 

Setting up and taking down this many panels takes some time, but I was impressed by how easy and intuitive it was. That’s because Jackery streamlined the number of ports on each unit, making it that much clearer what cable connects to what unit in what port. 

While at first glance there might appear to be a disconnect between the charging time capabilities of this setup and its battery life, it’s worth keeping in mind that conditions are not always optimal. One of the things that impressed me most about these units is the panel’s ability to generate electricity in lowlight conditions. Even in complete shade—dusk fast approaching—a single SolarSaga 200W was generating a 6 watt input.

How to Choose the Best Portable Generator 

The best way to choose a portable generator is to consider what you need it for and how much you want to spend. Budget and needs first, right? My needs would be to power at least a fridge or freezer possibly for days in the aftermath of a devastating tornado, based on where we live. My budget? I’d spend whatever I needed to take care of my family in such a situation. Your considerations may be the same. They may be that you need one to restore or build a cabin in the woods. Or you camp frequently but enjoy having lights and a small fridge. When researching portable generators, look for the wattage output, safety features, amount of fuel it holds, weight, and the size of appliances or tools it can safely power.

Solar vs. Fuel Generators

Solar generators are one of the latest innovations and offer some appealing benefits over their fuel counterparts. The solar panel charges a portable power station, which is what you’ll use to power appliances, power tools, or charge your phone. These portable power stations vary in size and power output, so it’s important to match the power station to what you plan to power with it. The negatives of solar generators is that unless your power station is fully charged, you have to wait sometimes an entire day for the sun to power it up. That’s not ideal during a storm.

Fuel generators on the other hand can be used no matter the sun exposure, providing you have fuel. Of course, their downside is that they are loud and produce carbon monoxide—you can’t use them indoors.

If you’re looking for a portable and quiet way to power small appliances, a solar generator is ideal. If you need a lot of reliable power you still can’t beat a fuel generator.

FAQs

Questions you may have when buying a portable generator.

Methodology  

Choosing the best portable generator was challenging, thanks to the wide variety of models available today. I evaluated the available generators based on the following criteria:

• Amount of power (wattage) produced
• Amount of fuel the generator holds
• Total runtime on a full tank of fuel (Full- and half-power runtimes are great to know, too)
• Weight and portability (Does it have wheels? Handles? Could one person move it?)
• Safety features (Does it have a carbon monoxide sensor? Low-oil sensor? Automatic shutoffs?)

The amount of power produced determines what the generator can be used to power. Some models can run a small lamp and charge your phone, while others can run your refrigerator, air conditioning, and other essential appliances. 

The amount of fuel your generator holds and it’s runtime will determine how long your generator will run before a refuel. It also impacts the portability of your generator. Other factors for portability include weight, wheels, and handles. If you are using your generator for home use or camping, safety features like carbon monoxide detectors, and automatic shutoff offer peace of mind.

Final Thoughts

Having lived in the Southeast all my life, I’ve seen the aftermath of natural disasters and how portable generators help get people moving again. After a tornado or hurricane, a portable generator can provide hours of electricity for power tools, appliances or even just lights at night for comfort or security. But you have to plan ahead. Finding a portable generator in that situation, not to mention fuel, could be challenging. A good portable generator also is great to have at your hunting or fishing camp if you need electricity to run a cooler or other items. They’re a great investment.
