What happens when you lose your electricity source in the middle of the night? All your equipment including the TV, the phone, the Wi-Fi router, would stop working at once. In that case, you might need a generator. An electricity generator does not only provide power in case of blackouts, but also shows itself as a cool gadget in picnic trips, BBQ outdoors, or camping. In this article, wildriverreview will talk about the best generators under $500, and how to choose the best of them.

Buying Guides

1. The watts

Here is the list of the most popular wattage ranges provided by a generator:

  • Less than 3000W: 3000W and below generators are considered small and most portable. Devices of this type are enough for small families with some basic devices such as a TV, a computer, a few lamps, or a fan.
  • 3000W - 7000W: Average power rate provided by generators. This type of generator can support the average use of families, with a few lamps, a fridge, or an oven, perhaps.
  • 7000W - 50000W: The most powerful range of wattage for a generator. The type of generator is sufficient to provide for a large family with lots of equipment. However, the power comes with the cost and the noise. Therefore, it is not recommended to buy generators in this range if you don’t plan to use that much.

In conclusion, we advise you to try to estimate the power usage of all the devices and equipment you need, then choose a generator with the power rate of 1.5 - 2 times of the wattage you estimated.

2. The battery

The generators don’t only come with the generator itself, but some brands might equip their devices with a battery. A battery is useful when you want to store the electricity generated for a short while, or when the power you actually use is lower than the power generated. A battery is not only a way of storing electricity but also a way to reduce fuel usage, noise, and carbon emissions.

3. Output voltage

Below is the list of voltage and amperage of popular generator outputs:

  • DC 12V - 5A: 12V is made specifically for lamps, phones, laptops or monitors. This output usually makes it into the generator as an essential port
  • AC 110V: AC 110V is what every American and Japanese uses everyday at home. AC 110V can be converted into AC 220V and vice versa.
  • AC 220V: AC 220V is what every person in the world other than Americans and Japanese people uses everyday at home. AC 220V can be converted into AC 110V and vice versa.

Although the currents can be converted into another, voltage to voltage, AC to DC and vice versa, it is obviously better to have it pre-installed on the generator.

4. The size

There are two main design for generators, which are the portable type and the stationed type:

  • Portable generators: Portable generators are usually designed with a handle for users to carry around. Portable generators don’t usually generate strong currents or wattage, but use less fuel and produce less noise.
  • Normal generators: Normal generators are big, loud, and fuel consuming. It can generate as much power as you require.

The last factor that would affect your choice is the color and the style. You had better choose a generator that looks cool with the internal look of your house, your room, or your car.

5. The fuel for the generator

When electricity doesn’t play the fuel part anymore, there comes a few alternative sources of energy. The traditional energy sources are being used to power the generator. However, some of them might come with a few disadvantages:

  • Gas fuel: Gas has been used for cars for hundreds of years now; therefore, when it comes to the idea of powering the generator, gas was the first to think of. Gas is cheap, fast to refuel, and releases lots of energy to turn into electricity. However, using gas in generators might contribute largely to the carbon emission that helps increase the effect of the greenhouse.
  • Propane fuel: Propane doesn’t make any difference than gas powered generators. Propane is considered to be even more power-effective than gasoline. Although gasoline is considered very dangerous to use with the generator, propane does even put more danger on the users.
  • Solar powered generator: Solar energy is safe, clean, and environment-friendly. However, the disadvantages of solar energy is that you can not get any energy or a very small amount of it on rainy or cloudy days. Provided that you use the generator under a very bright sunny sky, you could never reach the wattage produced by the weakest gasoline generator.
  • Wind power generator: This type of generator is considered to be impossible at the moment. It requires a very big fan and a high position with lots of wind to generate real electricity. You could expect some kind of wind powered generator in the future, but for now, there should be no hope.
  • Hand rotating generator: The generator uses the force from your hands to rotate the turbine and produces electricity. This type of generator is usually very small and suitable for emergency situations when the access to the fuel sources above is out of reach.

Among those energy sources, gas and propane are two most popular sources because of their performance, though they are considered being dangerous and not recommended with children because of the safety concerns.

1. What about the warranty?

All of the generators we introduced in this article are warranted for at least one year. Therefore, there should not be any kind of worries about your generator breaking. However, in our opinion, if you use the generator properly, you would never have to take your generator to the warranty center, because a generator can’t just break out of nowhere.

2. What is fully-shut-off technology?

Fully-shut-off technology is the name advertised by brands, which indicates the technology that dries out all the gasoline left in the carburetor before shutting down the generator. Because of that solution, there would be no fuel left inside the tank when you store it for months, thus, resulting in no engine damage.

Fully shut off technology is usually made into a premium electricity generator that usually costs over $1000.

3. What power rate should I choose out of my generator?

To choose the power rate you need of a generator, you should follow the below procedure:

  • List out the essential devices and equipment you plan to use with the generator.
  • Calculate the sum of the power required by the manufacturers for all the devices listed above.
  • Make some adjustments if needed
  • Choose a generator with the power rate being in the range of 1.5 to 2 times higher than the value you have in the previous step

4. Can I use another fuel type for my generator?

No, and it is not recommended at all. If your generator is designated to be used with gas, use gas for it. On the other hand, if it works with propane, don’t try to use gas with the generator.

Some generators are designed to fit with both gas and propane at the same time, although it might cost you some more.

5. My generator supports 120V output? What about 240V?

The 120V output is designed for American households; therefore, if you live in the United States, there would not be concerns about the voltage.

If you want your generator to be compatible with devices made for markets other than the United States, you might need an adapter, which can be purchased separately.
