Portable Generator Recommendations


Portable Generators Buyers Guide

You can skip straight to the portable generator recommendations here.

If you're looking for a standby generator that kicks in as soon as the power goes out, check out these standby generators instead.

Budget: Price doesn't necessarily equal quality, but many of the cheap portable generators are cheap for a reason. Sometimes it’s because the specifications don’t match up to the higher end products. Other times, it’s because the generators are second-rate products with reliability issues and manufacturing defects. Looking at the specifications and reading a few reviews will soon help you distinguish the difference between "good value" and just plain "cheap".

Reliability: This is extremely important, since you may be wanting to use your generator for emergency backup power. If you and your family get stuck in a storm, natural disaster or zombie apocalypse, the last thing you want is for your generator to die! Especially in a zombie apocalypse, since whomever draws the short-straw isn't coming back, it's a one way trip and you know it.

Noise: Having a noisy portable generator running in the background can become a huge annoyance to friends, family and neighbors. Now you can look at the dBA rating of each generator and try and find the quietest one, however, the ratings can be wildy inaccurate and there's not a significant amount of difference between most generators. If you want a quieter generator, look for one with a Honda engine or even the Yamaha EF2000iS which is fantastic if it meets your wattage requirements. Also, you can check out this video series on building a generator enclosure here which can help to reduce the noise.

Here's a decibels comparison chart to give you an indication of the loudness

Wattage: Before you buy a portable generator you need to establish your wattage requirements. Using a portable generator to power one or two appliances in an RV for instance, is a lot different from using a generator to power every appliance in a large family home. I suggest tallying up the wattage requirements of every appliance you’re likely to use. It’s best to err on the side of caution, and make sure the generator wattage exceeds the total amount you’re likely to need… Better safe than sorry!

Here are some common household appliances that may be run to give you a rough idea of your wattage requirements.

ApplianceWattagePeak Wattage
Light bulbs x17575
Refrigerator (1/4 HP)5002000
Freezer (1/4 HP)6001200
Sump Pump8002000
Electric Oven34103410
Washing Machine11503400

Obviously I don’t know your personal requirements, what appliances you intend to run or even the wattage totals of YOUR appliances (the figures above are just estimates). I suggest using this wattage calculator tool here to get a rough estimate of your requirements. If you intend to use a number of higher wattage appliances simultaneously, such as air conditioners, ovens, washing machines and so forth. The generator you choose will require a much higher wattage capacity.

Transfer switch: It’s recommended that you invest in a transfer switch when buying a generator (assuming you’re using it for backup power for your home). The transfer switch connects to your home circuit box, which does away with the need for numerous extension cords. It also protects the generator, lights and appliances from any potential damage when the grid power comes back online. I would definitely recommend having a transfer switch installed by a professional electrian, however, if you're a DIY kind of person, there's a good instructional video here.


  • Don't Run Indoors: You should NEVER run a generator inside your home due to the carbon monoxide buildup which can potentially kill or seriously harm you and your family. Always run a generator away from your home, doors, windows, vents and any openings to your home.
  • Clean Level Surface: Always operate your generator on a level surface, and in a place where it won’t be exposed to undue moisture, dust and dirt. Also, make sure that there’s enough clearance on all sides of the generator (at least 5 foot on all sides).
  • Fuel Expansion: It’s recommended to leave an adequate amount of room for fuel expansion, so do not overfill the tank. Also, never add fuel while the generator is in use, make sure it cools down first.
  • Electrical Wiring: Do not connect a portable generator directly to an electrical outlet / house wiring. If you need to connect a generator to your home's electrical system, use a transfer switch as mentioned above. Also, it's recommended to have an experienced proffessional check over your installation, or get a qualified electrian to install the transfer switch in the first place.

These are some things to keep in mind when looking at potential generators.

If you need a generator with a large wattage capacity, go for the Generac. Personally, I'm not too fond of Generac products because they have a reputation for poor customer service. If you're only concerned with having a high wattage generator and you don't care about CS and support down the line, then go for the Generac. If you are concerned, then the Powermate is a great choice assuming it meets your wattage requirements.

If you intend to use a generator for home use, i.e. for backup during a storm and you don't mind paying for premium. It may be worth looking at some of the stationary standby generators that are designed to kick in automatically during a power cut. They are typically more expensive than portable generators, however, they do offer a number of advantages.

If you own any of the portable generators mentioned in this article, please feel free to add your own comments to help others.

All comments (except for spam) will be accepted, even if you disagree with the winners selected. If you believe another generator should take the top spot, don't just leave an unhelpful comment, state the name of the generator and include a link to the best place to buy it.


  1. this is one of the best comparison sites I’ve seen in a while, i will be sure to recommend this to a couple of people, great job

  2. What would you recomend as one of the quiestest generators?

    • Well none of them are really quiet, but anything with a Honda engine should do. Also, the Yamaha Inverter generator is very quiet and very well rated.
