As we already mentioned earlier, there are plenty of generator models and brands available in the market for you to choose from. However, it is a good idea not to settle for the cheapest generator very quickly. You should compare the prices vis-à-vis the features, quality, reliability and your requirements before you settle on a specific portable generator for your home or outdoor needs.

Factors to Consider When Buying a Portable Generator in the $500 Range

There are a plethora of brands and models of generators around the $500 or less range and choosing between them can be a rather difficult task. Here are a few tips that can help you choose the best generator which is affordable and is the best-suited for your workplace or home.

  • Before making a decision about the generator you are going to buy, you must ascertain the total power requirement and the appliances you plan to operate using the generator. The generator should be able to handle the load, as a load higher than the capacity of the generator will cause it to get overloaded and trip. Also, if you plan to use the generator for prolonged periods of time, you should buy one with a tank size that is large and which can accommodate sufficient fuel for a long period of use.
  • Another important aspect to consider when buying a generator is the type of fuel you want to use to power your generator. You should evaluate the various fuel options available and their benefits in terms of the price, availability, and storage of the fuel.
  • You must consider the factor of fuel-efficiency of the generator before buying a model priced less than $500. Make inquiries and check around for the brands and the models that offer energy efficiency in the long term. Check the other factors such as the size of the gas tank, running cycle, etc.
  • Select a generator that offers ease of operation. The generator should be easy to assemble, install, operate and also refuel. Look for added features such as safety switches that trip the generator in the case of an overload, low-oil indicator, and shutoff, etc.
