What to consider buying the best electric generators

Electric generators are complicated machines. Knowing the various types of generators and how they work will ensure your generator or power station of choice offers efficient, safe electricity whenever and wherever you need it. 

Do you need a gas-powered electric generator or a battery-powered generator?

Gas-powered generators can be big and noisy, yet powerful. These heavy beasts turn gasoline into controllable lighting, and that’s no easy task. The bigger gas generators are used as whole-house generators and can provide efficient backup electricity when the power goes out. Some can be wired into your home’s electricity for a seamless transfer of power. But whole-house generators are not cheap and they often need to be installed by professionals. Smaller, portable gas generators are great at keeping major appliances running, such as refrigerators and air conditioning units—but they need space to give off deadly carbon monoxide gas. (Never use them indoors, even in a garage with the door open.)

Battery-powered electric generators, meanwhile, are often called power stations because they’re not actually making the electricity, simply storing it. They’re becoming more and more popular. These generators provide just enough electricity for phones, laptops, TVs, and other devices that are not as wattage-hungry as big household appliances like washing machines. They are cheaper, lighter, and much more portable than gas generators. And they can safely be used inside the home. 

If all you need is a power source for charging gadgets and staying connected to the outside world, a portable electric power station that runs on a rechargeable battery is the best solution. 

Understanding the backup-generator power rating

Looking at the stats and specs of even the most basic generator can be confusing. The two numbers to look for are running wattage and surge or starting wattage.

Running wattage refers to the power needed to keep a device working. Because most appliances need an extra boost of power to start and get up to speed, the generator will also list a starting wattage to show how much juice you need to get things going. 

For a whole home generator, you may need a unit that offers up to 8,000 watts. This will run most appliances and essential electronics. But if all you need is a portable generator for charging devices, you can survive on a generator that only offers 100 watts. 

Make a list of all the appliances you want to run if/when the power goes out. Use this as a rough guide to predict how much wattage you’ll need. Give yourself plenty of wiggle room by opting for a more powerful generator. 

Portable power stations will often list wattage hours (Wh). This means if a generator is rated at 200Wh, it can run a 20-watt device for 10 hours. Keep in mind that the specs listed apply only if the generator is fully charged. 

Pay attention to charge time and fuel for the best electrical generator

Besides power output, the most important thing to look for in a battery-powered electric generator is the charge time. Many power stations can either be plugged into the wall or car outlet, or use solar panels to fill up the battery. But it can take time; a 160-watt battery needs at least five hours of consistent AC-wall-outlet power for a full charge. And when disaster strikes, you won’t have five hours to spare. If you go for a battery-powered generator, be diligent about charging the station. Solar generators take even longer. Plan accordingly.

Gas generators will need fuel, of course. Many can be filled with standard gasoline, but propane tanks will last longer. Whole-home generators, and some portable gas generators, can be connected to the home’s natural gas line for dependable power. Natural-gas generators are more efficient and more earth-friendly than gasoline generators. Whatever fuel source you use, stock up and be ready for whatever weather comes your way.

Are portable electric generators really portable?

Even if the gas generator is advertised as portable, it may still require some muscle power to maneuver. These gas generators can weigh hundreds of pounds, and even with wheels and handles, it can be grueling to lug them around on camping trips. 

Battery-powered energy stations are much more portable, weighing less than 20 pounds. Travel generators may weigh only two pounds and have enough power to charge a phone nearly ten times. 

What is a power inverter and how does it help?

An inverter generator takes DC power, converts it to AC power, and then converts it again into DC power. Why the back and forth? To put it simply, the power will be more consistent and efficient when inverted from DC to AC and back to DC. This is ideal for sensitive electronics such as laptops. Inconsistent power or power surges can wreak havoc on high-tech devices. The clean power output of an inverter generator is safer. The downside: Inverter generators cost more than standard gas generators. But they are also quieter than gas generators and more efficient, so it may be well worth the money. 

Finally, noise is also a crucial stat for gas generators. Loud generators coughing up 90 decibels can ruin an outdoor event. Battery-powered energy stations are quiet because they lack an engine, but they also lack the big power output of gas generators. 

FAQs

Q: What size generator do I need to power a house?

To power a house, you’ll need at least 4,000 watts of electricity. That will run basic appliances and electronics without too much trouble. But for a complete, whole-home generator, you may need up to 8,000 watts. These natural-gas generators can run all the lights, heating/cooling systems, and household appliances of a mid-sized home. They won’t be cheap, but they do provide reliable energy and can hook into your home’s existing natural gas line. If all you want is a power supply for electronics like laptops or CPAP machines, you’ll only need about 200 watts to get through a few nights. The size of the generator depends on what you want to operate. Hair dryers and blenders are notoriously high-wattage machines. Mini-fridges and electric grills won’t need nearly as much power. 

Q: What type of generator is most efficient?

Natural-gas generators are the most efficient for powering an entire house. Gasoline and propane generators are the most efficient for RVs. But for keeping TVs and computers running, the most efficient power supply will be a rechargeable power station like the Jackery Portable Power Station Explorer 1000. These easy-to-use power stations keep phones and tablets running without burning fuel. They are also quiet and safe to use indoors. 

Q: How do I choose an electric generator?

Choose an electric generator by considering all of your options. Gas generators are the standard method of bringing power to the powerless, but the fumes, weight, and noise prevent these big engines from being in-home power supplies or good portable camping generators. Electric, rechargeable power stations provide less wattage but are safe and ideal for laptops, TVs, phones, and other electronics. And if you want a whole-home generator to be the backup power for all appliances, you’ll need an 8,000-watt natural-gas generator. The type of electric generator you need depends on what you’ll need to keep running when the power goes out.  

Final thoughts on the best electric generators

The best generator will be a powerful resource that’s as dependable as it is efficient. The size and type of electric generator will vary based on how you want to use it. Big gas generators are great for big appliances. Power stations are great for small devices. And natural gas generators are great for keeping the entire home running smoothly. Whatever generator or power supply you choose, make sure it’s ready to work whenever you need it—that means keeping it fueled up or keeping the battery charged. The best electric generator can be a powerful resource if used correctly.
