Is it possible to jump start a car without jumper cables?

Absolutely, you can jump start your car with a jump box or using a portable battery pack. It is important to get the right type of jump starter, and that is going to depend on your car’s engine type.

You want to make sure you get a unit that has enough capacity to jump start your vehicle. The power required to jump start a vehicle varies. You will need 400 to 600 amperes to start a normal size vehicle.

For most small-size cars, 150 amps are sufficient. For those who own commercial vehicles, they may be required to get a device with 1500 or 2000 amps.

How to Jump Start a Car Battery Without Another Car

Jump starting your car without jumper cables is a fairly simple process. Most battery packs come with spark-proof technology, so you don’t have to worry about being shocked.

The process is similar for any vehicle with a 12-volt battery (most cars) and can be done by following these steps:

#1 Find your battery pack and go to the car

The first step should be to find your jump starter and to go to the car that you are going to be jump starting. You want to make sure that the jump starter that you are using has enough capacity to charge your car’s battery.

Check the device and make sure it is fully charged. It’s also important to park your car in a safe location before you start with the process.

If you are stuck on the side of the road, use flares or cones to prevent other drivers from getting too close as you start your car. We suggest using gloves to handle the cables and wearing protective clothing.

#2 Turn off all electric components first

Turning off all electrical components of your car before jump starting is an important safety measure.

You want to make sure that the engine and battery are not receiving any power during this process, so you need to turn off headlights, wipers, A/C, radio, or anything else before connecting your jump starter.

#3 Open the hood and find the battery

To open the hood, you will need to locate the release lever. It should be near the base of either the front door or on the driver’s side for most cars.

Then you would need to locate the battery and identify the positive and negative terminals. Both of these should be labeled, or there may be a diagram on your owner’s manual.

Inspect the terminals that attach to the negative and positive sides of the battery (typically found on top). These are usually color-coded: black for negative/ground and red for positive/charge.

#4 Connect the clamps to the terminals

Connect both of the red clamps directly onto the positive terminal and the black clamp directly to the negative terminals on top of each battery post with care.

Make sure that you secure the clamps to each terminal. Try not to touch them together as it could create sparks which can be dangerous!

#5 Turn on the ignition or push the start button

The last step would be to push the start button on your car. In most cases, you would just need one try to jump start your car. However, if by any chance your car does not start on the first attempt, give the charger a few seconds and try again.

Don’t forget to remove all clamps from each terminal. Do this in reverse order: red clamp off the positive post, black clamp off negative posts. Be careful and try not to touch them together to prevent sparks.

Why is your car battery dead?

The typical battery of the car consists of two lead plates which are submerged in sulfuric acid, the electrolyte. When you have a dead battery, these lead plates are not touching because there’s no current flowing through them.

There are two types of batteries in cars: lead-acid and lithium-ion. Lead-acid uses water as an electrolyte, while lithium-ion does not require this liquid as it’s an internal part of the battery cell design.

Lithium-ion is lighter and does not require a lot of maintenance like lead-acid. Most batteries die because they’re not used for a long time.

They can also die if you try to charge it too quickly after it has quit working and is drained of power. Make sure you disconnect your battery if you’re not going to be starting your car for long periods of time.

How do you start an automatic car with a dead battery?

If you have an automatic transmission, the process is fairly simple when you use a simple portable charger.

There are plenty of jump starters to choose from, and it takes just a few minutes to charge a dead battery. The best part is that you can start your car without using jumper cables.

All you would need to do is pop open your hood and locate the battery. You can find a positive (+) and a negative (-) one at end of each wire attached to the battery.

Attach the red clamp onto a positive post and the black clamp onto the negative terminal. Finally, push the start button. Unfortunately, you cannot use the push starting method when you have an automatic transmission car.

Another option would be to purchase a new battery. If your car dies in the middle of the road and you do not have a portable charger, your best bet would be to call for roadside assistance. You can find the number printed on your insurance card.


When you are trying to start your car without jumper cables, the following questions might prompt:

What is a jump box and how does it work?

A jump box is a small device that can jump start a car. It is not as powerful as the jumper cables, but it will still help you in emergency situations when you need to recharge your vehicle’s battery.

The small box comes with integrated cables that you hook to the metal posts, and it can be stored under the driver’s seat. The best part about these chargers is that they come with USB ports that can be used to charge your cell phone, laptop, or tablet.

It provides is a safe and convenient way for you to have the ability to recharge multiple devices, and they can be a lifesaver when it comes to dead batteries.

Can you jumpstart a dead car by yourself?

Absolutely, with the help of a portable charger, you can do it yourself. You won’t need to use your jumper cables anymore, and the process for using them is pretty simple.

Some will include the option to charge using the cigarette lighter outlet. Purchasing this portable device is proven to be a good investment.

How long should you jump start a car for?

Once the engine starts, you should let it run for a few minutes. If your engine is not starting on the first jump, give the charger a minute or two and try again.

You want to make sure you drive your car for about 30 minutes after the engine starts so the battery can continue to charge.

Does revving the engine charge the battery?

Revving the engine will allow you to reach a higher voltage level on your battery.

The alternator starts running faster, and it begins supplying more electricity and amperage, which is really good for when you need that boost, especially during cold weather situations.

Can you use the push starting method?

This is one of the oldest methods used to jump start your car. It only works if your car has a manual transmission. You will need extra spare hands to help you push the vehicle.

The driver will place the transmission in second gear and wait until the vehicle has enough momentum build up. Then the driver will need to release the clutch quickly. At this point, the transmission will turn over the engine and cause it to start.


If you have tried the previously mentioned methods and have not been able to start your car, there is a good chance that you have a bad starter or an alternator problem.

Call roadside assistance so that they can send a service tech to help you with your vehicle problems. As you can see, you can start a car without using another car.

This can be done by using a portable device. All you have to do is connect the device to the battery and press the push start ignition button on your car. Make sure you use all safety precautions.
