Champion 5000W - Built With Safety In Mind

Using a generator is generally a safe procedure, however, if not careful, there can be unnecessary risks. The Champion 5000 was built with safety in mind to keep you and your generator as safe as possible.

The Champion 5000 is pushing out 5000 watts and has a run time of 9 hours at 50% load.

While this seems pretty standard, it’s the built-in safety features and 152 lb weight that makes the Champion stand out from the competition.

This Champion generator features a low oil shut-off sensor that automatically shuts your generator off when your oil is running low to prevent damage to the 292cc motor.

This is vital as checking the oil is a commonly looked over maintenance task and can cause catastrophic damage to your generator.

Buying Guide - Frequently Asked Questions

What is the quietest 5000 Watt generator?

Generator noise level is measured in decibels from 23 feet away. For this list, it is a tie between the Westington and the Pulstar generators, with both of them producing 72 decibels from 23 feet.

An important note to remember when thinking about noise levels is where the generator will be replaced.

A more powerful, louder generator may be suitable for a job site where noise isn’t as important.

If using in a residential setting, a quieter generator may be better suited.

What is "starting" and "running" watts?

This is a very common question when dealing with generators.

Let’s start off by defining a watt to help better understand starting and running watts.

A watt is a unit of measure that describes the rate at which energy is used,

or produced, or moved from one place to another.

Starting watts are the watts required to get the generator going from a static position. Starting a motor requires more work than keeping it running so most generators have a high rating for starting watts.

Running watts are the watts required to keep the generator going.

Keeping the motor running requires less work than starting the generator, so the ratings of running watts are usually lower than the starting watts.

Can it run this or that appliance?

In order to find out which generator will run what appliance, you must first determine which appliances you will need to power and how many watts they require.

Safety tips and precautions when using a generator

  • Never operate a generator indoors.
  • When running, the generator should be at least 15 feet away from any open windows or doors.
  • Don’t run a generator when it’s raining.
  • Turn the generator off and let the engine cool before refueling.
  • If using an extension cord, make sure it is heavy duty and in good condition.
  • Install a transfer switch to power hardwired appliances safely.
