Does Revving The Engine Help Jump A Car? (Explained)

As a car driver, it is normal to have a dead battery. You might be driving somewhere, or your vehicle might be in your garage, but a dead battery is not new and can be experienced by any car driver. The bad thing is if you have a dead battery in a remote area, then you might have to jumpstart your car. 

When we say jumpstart a car, it basically means that you have to give your vehicle a boost. This is a method that is done by car drivers to start a vehicle that has a discharged battery on it or a dead battery.

Most car drivers already know how to jumpstart a car, but some of the car drivers are still not experts on how to jumpstart a vehicle. In jumpstarting a car, there are steps to be followed. The basic jumpstart of a vehicle consists of only a few steps. 

But many drivers wanted to know if revving the engine would help jumpstart your vehicle. So we have made this article to answer this question. 

In this article, we will be focusing on the discussion of whether revving your engine can help while jumping your vehicle. So let’s go.

Does Revving The Engine Help Jump A Car

Should I Rev The Car When Jump Starting?

The voltage output is regulated to a maximum of fewer than 15 volts. The voltage will push the electricity through the wires while the amperage measures how much the electricity is following. Let us imagine a garden hose. 

The voltage is the water pressure, while the amperage is how much the water will leave the nozzle. If you increase the engine’s speed on the donor vehicle, it will make enough amperage or current flows into the weak battery. 

Yes, you can rev your vehicle when you are jumpstarting to answer this question. You can hold it around 1,200 RPM.

Does Revving Engine Charge Battery Jumping?

Revving the engine during a jumpstart might not be a bad idea. You do not want to floor or accelerate the gas pedal in any situation, but if your engine turns faster, your engine’s alternator will also turn faster. If the alternator turns faster, it will then produce more electricity. 

And so if you rev your engine up to 2,000 RPM or 2,500 RPM and hold it there while the other vehicle tries to start, you are increasing the output of your alternator, and this will give your battery a little bit of excess power. It will also donate to the other vehicles. Depending on the sizes of the respective engines and the battery’s condition, that extra power can make a difference. 

Should You Accelerate While Jumping A Car?

You do not want to floor or accelerate our gas pedal, but if the engine turns faster, the engine’s alternator will also turn faster. And if the alternator is turning faster, more electricity will be produced. As a result, your battery will charge faster if you rev the engine. 

This is because more power is generated. After all, the alternator will turn faster and produce more electricity that will charge the battery. 

How Many RPMs Do You Need To Jump A Car?

Rev your vehicle for about 2000 or 2,500 RPM or revolution per minute. You can maintain it at that, and it will increase the output of your alternator and will give more power to donate to the other vehicle. 

The jumpstarting of a vehicle might not be the same with all the vehicles. This is because this can also depend on the battery of your vehicle.

How Else Can You Help Jump A Car?

Revving your engine can help. Accelerating is a debate and is done or not at all. 

There might be some other things that you can do that only experts know. You can ask for experts for any things that you can do while jumping starting your vehicle. 


In summary, jumpstarting a vehicle must be known to all car drivers. This is because a dead battery can happen to anyone. 

Revving your engine while jumpstarting a car can help. However, accelerating your car might be a different story.
