No one should be without an inverter generator. Whether there’s a power outage in your neighborhood or you’re gearing up for a camping trip, a portable generator with an inverter is something you can’t live without. Inverter generators offer clean, on-demand electricity that can power a multitude of appliances and electronics, so you’ll always be prepared for life’s adventures.
What Is a Portable Inverter Generator
Portable generators that don’t have an inverter create power in the form of DC, or direct current, which means you can safely hook them up to an array of appliances. In comparison to inverter generators, conventional generators generally over a higher power output, and they can be used for a longer period.
While portable generators with an inverter also create DC power, they take it and turn it into AC, or alternating current. The advantage of transforming DC to AC is how the current meshes with electronics. Since AC power is smoother, it meshes better with electronic equipment like smartphones and laptops that have sensitive microprocessors.
What Other Benefits Do Inverter Generators Offer
There are other advantages to using a portable inverter generator in addition to a cleaner electricity supply. Many of them are compact and lightweight without sacrificing power output. It’s common to find inverter generators that weigh fewer than 50 pounds, which negate the need for a transport dolly.
Although the size of a typical inverter generator means that it has a smaller fuel capacity than a standard generator, its engine uses gas more efficiently. This leads to long-term cost savings and fewer exhaust emissions.
Some inverter generators allow you to combine them with other like-models, so you can greatly increase the power output. This is called a parallel operation, and it’s not an option with standard generators. To take advantage of this feature, you’ll need a dedicated parallel cord.
What Are Starting and Running Watts?
When you read the specs of a portable inverter generator, you’ll see two wattage ratings listed. One is starting, or peak, watts, and the other is running watts. As the term suggests, starting watts is the wattage draw the generator uses upon startup, and running watts is the wattage draw it uses when in use. The starting watts are always higher than the running watts.

Should I Get an Inverter Generator With an Electric-Start Mechanism?
An electric-start mechanism makes it much easier to turn on an inverter generator. Instead of pulling a cord, you simply push a button. Both startup choices work reliably in cold and inclement weather. The only caveat to an electric start is if the inverter generator’s battery isn’t charged enough.
Is It Safe to Use an Extension Cord?
There are no safety concerns with using an extension cord as long as the cord is in good shape without any wear or frays. However, the length of the extension cord may cause a voltage drop. For example, there could be up to a 6-volt decrease with an inverter generator when coupled with a 10-meter extension cord, and that voltage drop could more than triple with an extension cord three times as long.
Is It Possible to Overload an Inverter Generator
You bet it is. Of course, the possibility is slim in newer inverter generators thanks to the inclusion of a built-in circuit breaker. When a generator is overloaded, the breaker trips, or halts, the flow of electricity, preventing the generator from overheating and catching on fire. If the circuit breaker trips, it only takes a few minutes to get the inverter generator running again. Be sure to lighten the generator’s load first.
What Do I Need to Know About Adding Oil?
Over time with heat exposure, the oil in a generator’s engine becomes old and ineffective. Neglecting to perform regular oil changes can lead to a premature failure of the engine and other essential components.
If you don’t put in enough oil, the engine will probably lock up. Inverter generators with a low-oil indicator and shutoff switch will alert you when the oil level is inadequate, and then the generator will turn itself off. However, you shouldn’t fully depend on this fail-safe mechanism. On the other hand, overpouring the oil may lead to degraded engine performance and an abundance of the exhaust.
How Loud Are Portable Inverter Generators?
Inverter generators have one purpose – to create power. Along with power comes noise. The exact level of noise depends on several factors, including the speed of the engine and the distance between you and the inverter generator.
Most generators with an inverter are quieter than conventional generators, and they can climb up to 85 decibels of sound. Some models make less noise, and situating the inverter generator further from your house or campsite can reduce the sound level.

A Buyer’s Guide to Portable Generators With an Inverter
Picking a portable inverter generator is tricky business – There are simply too many models from which to choose, and each of them offers a unique set of features. Here are the four most important categories of features to review before you plunk down your money on one of these backup power sources.
Portability
The main reason to purchase a portable inverter generator is to have a source of power you can transport. Therefore, the model you select should be lightweight. For a generator, lightweight means 50 pounds give or take.
It should also offer a firm place to grip with one hand. Some portable units have a carrying handle on the top while others are equipped with a surrounding frame. If the inverter generator can be paralleled, framed units allow you to stack each generator, which saves space.
Power Options
Manufacturers provide ways to either increase or decrease an inverter generator’s output. Generators that can be paralleled work in conjunction with the same type of inverter generator to produce twice the power output. Alternatively, an eco function reduces the engine’s RPMs to lower the generator’s gas consumption, providing a quiet, fuel-efficient experience.
Also, pay attention to the size of the gas tank. The higher the capacity, the longer the runtime. Ideally, you’ll want a portable inverter generator that can keep chugging along through the night.
Power Outlets
Of course, you’ll want the ability to power up a variety of appliances and electronics. Virtually every generator with an inverter comes with at least one DC outlet and one or two AC receptacles. There are also some models that offer a USB port for smartphone and tablet charging.
Safety
Older generators carried a real fire risk, but today’s inverter generators are chock full of safety features. Make certain that any portable generator with an inverter contains an auto-shutoff mechanism that kicks if the unit gets too hot or loses too much oil.
Preventing the damage that stems from overheating and low oil levels is easier if the inverter generator is equipped with indicator lights and alarms that alert you to these problems. Besides, the unit you choose should meet environmental impact requirements set forth by the Environmental Protection Agency and the California Air Resources Board.
