How To Find The Best Suitable Portable Generator In 13 Steps

If you wish to find the best portable generator on the market then you need to consider a few factors. Let’s have a look:

1) Fuel Type: Most light duty generators support gasoline and most big generators offer dual fuel system (gasoline and propane).

  • Gasoline: Gasoline is easily available and inexpensive. Plus, it is also easy to store.
  • Propane: It is more expensive than gasoline but works quietly. It may have a longer shelf life, but it’s also less energy efficient.

Tip: Choose one that’s more readily available and affordable for you.

2) Applications: The number of appliances you want to run should be at the back of your mind when you’re out to purchase a portable generator. Check out your requirements in terms of watts and ensure the generator can support it. Also, some light duty generators may not support big appliances even if they meet the watt requirements.

Tip: Some generators allow parallel connections to increase outage.

3) Starting Technology: No matter how powerful and popular a portable generator is, it won’t do you any good if you have trouble turning it on. Normally, generators have two starting methods: the recoil system and the electric button start system.

The recoil system requires effort and is stressful. Whereas, the electric button takes a second to start.

Tip: Some generators have both the options but the electric system is definitely more suitable.

4) Wattage Check: It is important to know the generator is not overloaded to ensure it or other appliances sustain no damage.

Some generators come with a voltmeter that reads and displays wattage reading.

Tip: If your generator does not have a voltmeter then consider if it supports a separate voltmeter.

5) Number Of Outlets: One of the characteristics of a portable generator that most people often overlook is the number of outlets it has. Multiple outlets make it easier to distribute load and connect various appliances simultaneously. It’s an excellent way of preventing overloading.

Tip: Ensure it has different types of outlets to support various devices.

6) Weight: Big and heavy generators can be a bit problematic to travel with. So pay attention to this feature and the dimensions as well so they are easily portable.

Tip: Pick a generator with wheels and a properly designed handle to ensure no trouble.

7) Noise: Generators cannot be completely silent so choose one that produces between 50-68 dB of noise. This equals to two people conversing at a distance of 23 feet. Noise will not be much of an issue if you want to keep the unit at a large distance but it can still result in noise pollution.

The higher the noise level of a generator, the more irritating it gets for the family and neighbors. Plus, it can also be a distraction and make it difficult to sleep or work.

  • 50 dB: People conversing, operating refrigerator.
  • 70 dB: Vacuum cleaner.
  • 80 dB: Blender.

Tip: The noise also often depends on the type of fuel and energy consumed.

8) Fuel Economy: The amount of fuel a generator consumes is of vital importance. Some generators are meant to drink up a lot of fuel which can be expensive.

Therefore, choose a generator that is economical when it comes to consuming fuel.

Tip: Generators that have a quiet mode, eco mode are good as they only produce the required amount of energy.

9) Runtime: The right runtime depends on your requirements. Pick a generator that offers extended runtime so that you have no trouble in case of an emergency.

Tip: You can reduce loud to increase runtime.

10) Price: The most important factor you need to consider is the price, of course. The rule of thumb is simple, if you pick a powerful generator with many features, it will cost more.

Tip: A portable generator is a one-time investment so make sure to be careful.

12) Warranty: Most reliable companies offer warranties so make sure to look into this factor. They can be between 1-5 years.

Tip: Some warranties require registration and may not be transferable.

12) Accessories: Some generators require additional accessories to install and run properly.

Tip: Make sure the generator comes with all the required accessories.

13) Safety: Safety is important as generators can malfunction resulting in not only financial losses but injuries as well. Look for generators that come with features such as automatic shut down. Other than this, ensure the tank is properly sealed.

Tip: Stay away from generators while they’re operational as they produce gases that may be harmful.
