Buyer’s Guide

When selecting the best gas generator for home, RV, or camping; consider these below mentioned factors.

Conventional vs. Inverter Generator

It depends on your power needs and choice. If you need a compact portable generator for your camping trips or tailgate parties, then an inverter generator is the best fit. On the other hand, for home backup power and RV use, conventional generators are recommended.

Inverters produce clean power. They are parallel capable, compact, portable, and fuel-efficient. But they are expensive as well and cannot give higher output power with a single unit.

Conventional generators can produce higher output power and are less expensive, but most of them don’t produce clean power. Also, most of them are noisy.

Amount of Power

How much power you need depends on your purpose of buying the generator. If you want to run your whole house, then a power generator is a must. If you need to run your RV, a mid-power generator of 4000 watts is enough. Or if you need to power your camps or tailgates, then a small portable generator with 2000 watts power is sufficient.

Tank Size and Runtime

Fuel efficient generators give good runtime with small-sized fuel tanks. So, if your generator is small but fuel-efficient, then you can get extended runtime.

Generators with higher output power need big size fuel tanks to give a decent runtime, so you cannot ignore the importance of having big size fuel tanks.

But one thing you should keep in mind that the more powerful your generator is, the more it will consume fuel to keep your life running. Also, the runtime depends on the type of fuel you are using.

Start System

Your generator must have an electric start system to start your generator without any effort. But if your selected generator is only featured with recoil start then make sure the rope is easy to pull.

Some generators also come with cold start technology that ensures easy starts in cold weather. Also, the remote start system is the most useful option that becomes mandatory for RV generators.

Operational Sound

Always try to buy a generator with low operational sound. It will not only keep you relaxed and allow you to have a good night’s sleep but will also keep your neighbors free from stress.

Most of the inverter generators are quiet so you can go for inverters, but if you need a conventional generator, then try to get a unit with less than 70 dB (A) decibel rating.

Also, you can keep your generator away from you if it is noisy to protect your ears from listening to the disturbing sound of the generator.

Power Outlets

The number and type of power outlets available in your selected generator must be according to your needs. If you need more power outlets to run your household appliances, then make sure your unit has two or four 120V 20A household outlets. If you need to power your RV, then a twist-lock or an RV-ready outlet is a must. Also, USB ports are best to have to power small items, and a 12V DC outlet can be used for battery charging.

Safety Features

Low-oil shutdown sensors and overload protection are the two common safety features.

Some generators come with a fuel shutoff valve to prevent stale gas related issues. Also, a spark arrestor is a must if you are buying a generator for camping or tailgate parties.

FAQs

How to store fresh gas in your gas-powered generator?

To keep gasoline fresh in your generator, it is necessary to add a fuel stabilizer in the gas tank. This fuel stabilizer will keep the gas away from gumming up. It can keep your fuel fresh up to a year or so.

Also, it is recommended to utilize the fuel shutoff valve if available to run the generator without gasoline supply to prevent stale gas related issues. The old gas will be used to run the generator, and this will help you in adding fresh gas without any hesitation.

How much gasoline should I store during a power outage?

It is always necessary and beneficial to have extra gasoline in your hands during a power outage.

For example: If you have a generator with a 5-gallon gas tank, then you need an extra 25 to 30 gallons to keep your life running for days.

How to keep a small gasoline-powered generator to live longer?

Regular maintenance and care can help you to keep your small gas generator in a working condition for long.

  • Check the oil on a regular basis
  • Keep your generator covered when not in use
  • Do regular service
  • Do inspect the battery and connections
  • Avoid overloading
  • Before adding gasoline, run your generator without fuel to prevent stale gas issues
