When compared with expensive brands like Honda, Predator stands out to a better recreational generator. It costs half as much and offers the same performance and features. Conventional generators by Predator are louder than those by Honda, but the inverter generators are just as quiet, so you won’t even notice any difference.

Advantages of Predator generators:

  • All generators have a runtime of at least 10 hours at 50 percent load, which makes the brand one of the most fuel efficient in the market.

Disadvantages of Predator generators:

  • Other that GFCI protected outlets and low oil shutdown, Predator generators don’t have interesting safety features.
  • The generators tend to make a lot of noise, especially the conventional type. They produce at least 72 dB(A) of sound, which can be uncomfortable and distract you from your daily routine.
  • They are heavy, so don’t even think about carrying them from one location to another.

Generator type: inverter or conventional?

Inverter

Inverter 3,500-watt Predator generators

A new generator technology, inverter generator produces alternating current and it into changes direct current and coverts back into alternating current to produce sine wave. It is clean energy, which makes inverter generators safe for delicate devices including mobile phones, laptops, coffee makers, and hairdryers. Top inverter models by Harbor Freight include 2,000-watt and 3,500-watt Predator generators.

Conventional

Conventional generator is an old technology, which produces alternating current, which is then converted into direct current. It isn’t usually safe for delicate devices and tend to make a lot of noise.

How much power do you need?

Your requirements dictate your power needs. For example, if you want to buy a portable generator for your RV, you need a compact generator that produces 7,000 to 9,000 running watts to run the refrigerator, heater, and microwave. On the other hand, if you want a generator to carry out outdoor activities like lawn mowing and furniture building, a smaller generator will do the job.

The number of watts an appliance consumes decides the total power you will need. Here’s an average of how many watts common appliances at home use:

  • Ceiling fan – 120W
  • Hair dryer – 1,500W
  • Desktop computer – 200W
  • Central air conditioner (24,000 BTU NA) – 3,800W
  • Water heater (electric) – 4,500W
  • Clothes washer – 800 W
  • Smart phone (recharge) – 6W

How long you need to run your generator?

Predator generators' features

On average, an ideal generator should run for at least 10 to 12 hours at 50 percent load, so you can keep the air conditioner or heater running throughout the night without needing any refuelling. All Predator generators offer minimum 10 hours of runtime, making them a great choice to meet your power needs.

Safety features

Predator generators offer a number of safety features, including:

  • Low oil shutdown – to protect the engine from overheating and overuse.
  • GFCI outlet protection – to protect users from electric shocks and imbalance electric current

Tips and tricks

Here are a few safety tips you need to follow while installing and using a generator:
  1. To make sure that you have received a good model, test the generator as soon as you receive it.
  2. Always keep the generator at least 20 feet away from your house. The engine and exhaust fan should be directed away from the windows and doors of your house.
  3. Never use a portable generator in the rain because it can malfunction. Keep it in a well-ventilated and covered area.
  4. When the generator is running, place a battery-operated carbon monoxide detector near it as an added layer of safety.
