10 Best Portable Inverter Generators - Review 

1. Champion 3100-Watt Portable Inverter Generator

Champion 3100-Watt Portable Inverter Generator

When picking out an inverter generator, one of the primary features to pay attention to is how you get your power. Either you can run off of gasoline, or you can use a battery to provide the energy you need. This Champion Generator allows you to use either one. There is a switch that lets you convert to gasoline when necessary.

The other element to consider when picking out a generator is how many watts it produces. In this case, you get a max level of 3100 watts, with an operating level of 2800. This number of watts is ideal for operating multiple devices simultaneously, including high-powered appliances like microwaves and heaters.

What’s nice about this generator is that the power is “clean.” Even though it runs on fuel, you don’t have to worry about it cutting out and causing a short. Thus, you can plug in sensitive electronics, such as your laptop or cell phone. This generator comes with two standard outlets, as well as an RV plug (30 amps) and a 12v converter.

Because we’re looking at portable inverter generators, you want to be sure that you can bring the machine with you wherever you go. The Champion is extra convenient because it has wheels built in on the back, as well as a folding handle that lets you pull it like you would airplane luggage.

Finally, one neat feature of this particular generator is the inclusion of a wireless remote start. You can turn the machine on from up to 80 feet away, making it even more convenient and versatile, especially if you use it while camping.

What we liked:

  • 3100 watts
  • Built-in wheels for rolling
  • Folding handle for convenience
  • Wireless remote control
  • Clean electric start
  • Battery included and easy to replace
  • Two 120-volt outlets
  • 30-amp RV plugin
  • Operates at 58 dB
  • Lasts up to eight hours

2. DuroMax XP4400E 4,400 Watt Portable Generator

DuroMax XP4400E 4,400 Watt Portable Generator

Overall, when you’re deciding on the best inverter generator for your needs, you will probably want to go from the amount of watts necessary to power the devices you want to bring. In this case, you get a monster generator that produces enough power to run a small house. With an operating level of 3500 watts, there’s almost nothing that you can’t use with this machine.

Another element that you want to pay attention to with inverter generators is how long they last. Since you are using gasoline, you have to be sure that you won’t run out too quickly. In this case, with a four-gallon tank, you can get up to eight hours of continuous use at 50% capacity. That means that if you want to keep it running as long as possible, you should cap off at 1750 watts if possible.

One thing that we want to mention about fuel is that it does go bad. Thus, if you only use your generator in emergencies or not very often (i.e., once or twice per year), it can be a good idea to drain the lines after you’re done with it. Gasoline will evaporate and become less useful over time, so you never want to leave your generator with a full tank for very long.

As far as access to power goes, this generator has two standard outlets and one for your RV. Since it generates so much electricity, you can run your RV’s air conditioning without any problems (although it will suck up more fuel). To show you how much power you’re using, it does have a voltage meter on the side.

When it comes to portability, this generator has two folding handles with rubber grips. It also comes with thick rubber tires that can take on almost any terrain, making it ideal for camping. In fact, it’s rated as environmentally-friendly by the EPA, so you can use it in national parks without any problems.
