The Best 3 Yamaha Portable Generator Reviews

When you think of Yamaha, you probably think of motorcycles and not one of the best portable generator manufacturers. Well, in case you didn’t know, Yamaha is famous for not just their motorcycles, but a wide variety of other products as well.

[toc]In this article, we’re going to be focusing on their high quality line of inverter generators. They’re very well made and you’ll be surprised with the increase in quality that an inverter generator offers. In fact, you’ve probably seen them in your local Home Depot or somewhere similar as their bright purple color is hard to miss.

Inverter generators are specifically made different than other generators. They’re smaller, lighter, quieter, and much more fuel efficient than conventional types. Although they cost more per CC than conventional models, it’s well worth the cost to have the added quality that an inverter powered generator offers.

Inverter generators by Yamaha use gasoline as their fuel source, but run amazingly quiet. They’re also very portable, with 1,000 watt models about the size of a small cooler. As you go up in wattage, you’ll see that the more bulky generators have travel wheels, making portability easy. As far as fuel efficiency goes, you can expect some of these Yamaha inverter generators to run a full 12 hours without the need to refuel.

Overall, Yamaha inverter generators offer the perfect combination of light weight, portability, and power delivery. You can find Yamaha inverter generators between 1,000-4,500 watts. Of course, you should base your buying decision on your energy requirements. Some people will need a higher wattage and some people will need less, based on the appliances/combination of appliances they need to power.
