The Best 5 Portable Generators Of 2021

1. Honda EU2200i Portable Generator

Lightweight and compact at 46.5 pounds, the Honda EU2200i is the perfect portable companion for your home, job site, and camping trips. It can power a wide range of appliances that include small AC units, refrigerators, microwaves, hairdryers, etc.

Powered by the Honda GXR120 engine, this generator provides 1,800 watts of running power and 2,200 watts of surge power. It is a quiet portable generator with a noise level of 48 to 57 dBA. It’s hard to notice this generator working in the background as you carry on with your conversation or your sleep. With an average load, the 0.95-gallon fuel tank can run for 4 to 9 hours. Its impressive fuel efficiency is attributable to Honda’s exclusive Eco-Throttle system. Another great feature is its advanced Carbon Monoxide Detection System. It automatically detects dangerously high CO levels and shuts off the generator.

All Honda portable generators come with Honda’s advanced inverter technology. This is essential as you want to run your power-sensitive electronic equipment like computers, LED, DSLR, phones, tablets, security systems, etc., on a clean and stable power supply.

Preventing generator issues caused by stale fuel is easier than ever as the Honda EU2200i comes equipped with a fuel shut-off valve. Changing oil is also a simplified process with a bigger oil filler opening, longer spout, and larger oil drain gutter. Since the Honda EU2200i has parallel capability, adding more power is convenient. Now you can get double the power without having to invest in a heavier and more expensive generator. This is a huge bonus as heavier devices are difficult to maintain and operate.

You also get 36 months of residential and commercial warranty on this generator. Its increased durability is due to the high-quality magnets in its rotor, and the metal recoil rope insert. Read more user reviews at Amazon.

Faqs About Portable Generators

What Is the Most Important Feature To Check In a Generator?

Wattage capacity. It is important to check the generator’s wattage capacity against the wattage you need to run all your devices smoothly. Why? Simple. The generator’s output will determine how many devices you can run simultaneously. Don’t under or overestimate your home’s power needs by using our tips on calculating your wattage requirements.

How Many Watts Do I Need For My Home?

It depends on how much wattage you’re going to use at once. Check out this appliance energy calculator. Then add the highest wattage requirements of appliances you use simultaneously during peak hours. This will give you a rough idea of the wattage capacity needed to power your house.

What Safety Features Should I Look For?

Some safety features to look for are:

  • EPA, CPA, or CARB compliance
  • Circuit breakers
  • Spark arrestor
  • Surge protection
  • Low-oil and low-fuel shutdown

What Fuel Type Is Better?

It is generally better to go with a dual fuel type generator. Below are a few fuel types and their benefits.

Diesel: Diesel-type regulators need to be used regularly and are more expensive than the rest. However, the fuel itself is safer to store for long periods. It is low on maintenance and is also the most efficient fuel type.

Gasoline: Gasoline is the most common type of fuel used in generators. It is more efficient than propane. This is why it is easily available everywhere and affordable as well. Drawbacks include:

  • Low shelf life
  • Gasoline generators need to be refueled often and are higher on maintenance
  • Their lower flash point temperature makes them dangerous to store

Propane: Propane is less efficient than diesel and gasoline. However, if you’re the type to use your generator once and forget it, propane is better. It does not degrade as fast as the other fuel types when stored for long.

What Are the Best Generator Brands?

If you’re looking for reliable and well-established generator brands, consider Generac portable generators, Briggs & Stratton, Yamaha, Kohler, and Energizer.
