The top of the unit features a large acrylic lens that protects an LCD screen, which shows remaining battery life on the jump starter and whether or not it’s hooked up to another device.

How many amps do I need to jump start my car?

As you can tell, portable jump starters have a variety of specifications that could make it tricky to determine the right one for your vehicle. What you need to know is that jump starter power is typically noted in cold cranking amps (CCA) or peak amps (PA). To measure CCA, a fully charged battery is put in a cold environment—0°F—and determining how many amps it discharges for 30 seconds. This value explains what to expect from a battery in the worst starting conditions.

It’s true that the more amps a jump starter offers, the more powerful it is. But does that mean you should just purchase the most powerful product? Not necessarily.

What’s important is determining just how much power you need for your vehicle. Compact cars or even small sedans can be jump started with as little as 150 CCA, while full-size trucks and SUVs need around 450 CCA. But there are other things to consider, such as engine size and how old the vehicle is. Larger engines and older vehicles will require more amps to jump start, which is why you will typically see powerful jump starters advertised as being capable of starting engines as large as 8.0L. Generally however, 400-500 CCA is adequate to start most vehicles.

Keep in mind there may be times you have to help jump start someone else’s vehicle. Most of the products on this list will cover any passenger vehicle on the road today, but it never hurts to have something more powerful at your disposal, if you’re willing to spend the extra money.

How to Use a Portable Jump Starter to Restart Your Car

Every person should know how to jump-start a dead car battery — it’s just a useful life skill to have. Knowing how to jump a car will save you time and money so you don’t have to call a tow truck. While most people will wave down a passerby or call a friend to help with the jump, drivers can save even more time and do it themselves if they have a portable jump starter in their trunk at all times.

But if that’s not an option, here is a step-by-step illustrated and easy-to-follow guide on safely jump starting your car the traditional way. Bookmark this page on your phone so you have it handy in case of an emergency.

How to Tell If the Car Battery is Dead

Before you equip yourself with jump-starting skills, it’s critical to establish that the battery is the actual reason the automobile won’t start. If you turn on the ignition and the engine makes a cranking noise, a dead battery is not the problem and jump-starting it will be a futile exercise. Conversely, if the car is totally dead upon turning the key and there’s no noise, then it’s highly likely that you have a dead battery in your vehicle and jump-starting it is perhaps the only option.
