If you have ever been stranded on the side of the road with a flat battery, you already know what jump starters are – as you have probably looked into them. For anyone unfamiliar, let us introduce you to the car jump starter, also sometimes called car battery jumper box, jump starter pack or even booster pack.
The concept is rather simple no matter what you call it – a temporary connection is made to the battery of another vehicle, or to some other external power source. The external supply of electricity recharges the disabled vehicle’s battery and provides some of the power needed to crank the engine. Once the vehicle has been started, its normal charging system will recharge, so the auxiliary source can be removed.
You won’t use it 99 per cent of the time, but it will come more than handy when you actually do need to use it. As they say, the best car battery jumper box is the one you have when you need it but as most flat batteries happen when you least expect them, for instance, a road trip or when in a rush so when you don’t have one, the only other alternative to the jump start battery is jumper cables. The problem with jumper cables is that you’re left at the mercy of a kind fellow motorist to lend you their battery so you can jump-start your car. That’s not always possible, nor is it fast.
A great thing about car jump packs is that most of them are relatively small and don’t occupy a lot of space, so you can carry them around with you all the time. What’s more, most of them have lots of other practical and functional uses and features, but choosing the perfect one can be overwhelming if you’re not too familiar with the subject.
Reading the lines above you may ask: What is the difference between car battery jump starter, car battery booster pack and battery jump box? The answer is fairly simple – none at all, it is the same thing, just called differently.

Buying a jump starter can be confusing. When buying a jump starter, you will find that there is very little consistency among jump starter manufacturers in marking the jump boxes – some manufacturers list in their product specifications just peak amps, some cranking amps, cold cranking amps or just “amps”, some mAh and, quite usually, a combination of those. Some even list joules to confuse you even more. What’s the difference? Which one is a better reference and guidance to buying a jump starter for your ATV, car, truck or snowmobile?
Here is a little list of definitions to help you know what is what in the world of jump starter terminology.
Peak Amps – generally, peak power ratings are there to impress people. Always refer to the cranking amps and cold cranking amps when comparing jumpstarters.
Cranking Amps (CA) – refers to the amount of power that a battery can discharge for 30 seconds at 32° F (0° C).
Cold Cranking Amps (CCA) – refers to the number of amps that a battery can push out for 30 seconds at 0° F without dropping under 7.2 Volts.
mAh – A milliampere-hour (mAh) is 1000th of an ampere-hour (Ah). Both measures are used to describe the energy charge that a battery will hold and how long a device will run before the battery needs recharging.
In general, higher cranking amp ratings are better as this would be the actual power to start your battery. A jump starter with at least a 500 CCA rating should be able to start just about any vehicle with a dead battery. You can find more information in our Peak Amps vs Cranking Amps (and more) post.
Most cars have a 12-volt battery, but older, classic vehicles use a 6-volt battery, and so do certain tractors. Check your battery’s voltage and buy a jump starter pack matching your battery.
As far as the power of the jump box goes, the more the better. The battery needs to have sufficient peak amps, as well as cranking amps to start your car. In other words, most cars require modest power to start, but vehicles equipped with bigger factory batteries such as luxury limos, motorhomes and off-roads might need a more powerful jump starter. Again, make sure to pay attention to your own car battery and match the cranking amps.
How to jump-start a car?
Jump starting a car with a dead battery can seem like a difficult task if you’ve never done it before but it is not. Follow these 10 easy steps and jumpstart your car like a pro.
Battery maintenance and charging
Besides the alternator, the battery is one of the most vital components in every automobile’s electric system. It provides the juice to run all of your expensive electronic devices when the engine isn’t running, and when the engine is running, it plays a vital role in the proper functioning of the alternator’s voltage regulator. If you want to know more, read our Car Battery Maintenance and Charging post.
Car battery and extreme temperatures
The winter period is critical for car batteries. Drivers usually start thinking about getting a new battery when the frosts last a long time or are really tough. In a lot of cases, they only decide to change the battery when they are forced to as their car did not start that morning. What most people don’t know is that there are other factors… Read our post Did not start? The frost is most likely not what killed your car battery.
How Do Car Battery Jump Starters Work?
Although they might seem complex, car battery jump starters are actually fairly simple to understand. A car battery jump box helps your alternator (a small electrical generator located on top of your engine) when your car battery is dead.
It does this by providing an alternative electrical source and “kickstarting” the engine. A car battery jump starter doesn’t recharge the battery. It only provides enough electricity to get your car going.
Once your car is running, the alternator can recharge the battery while you drive around, but first, you have to get that car started! There are several main categories to think about when you are looking at how car battery jump starters work.
What types of car battery jump starters are out there?
When you first consider car battery jump starters, it’s important to know that there are three main types—portable battery jump starters, plug-in car battery boosters, and ultra-capacitor jump starters. Often, you’ll see different words used interchangeably to describe them, which can be confusing.
You can call it a car battery booster or a battery jump starter—it means the same thing. It’s an item that will help you start your car when the battery is dead without needing another car for the jump.
Other names that you might see are car battery jumper, car battery jump box, and car battery booster. There is no difference between what they are, and so we’ll use them interchangeably here. There is a difference, however, between those that are portable and those that are plug-in.
Plug-in car jump starters
Plug-in car battery booster packs are often bulky and large. They also require an outlet. Subsequently, plug-in battery jump starters don’t need to be charged in advance. This aspect can be an advantage because portable jump starters take a long time to charge. The need for an outlet makes them inconvenient, though.
Portable car jump starters
Portable jump starters are often smaller and more compact than the plug-in variety. However, they do need to be charged regularly. Because they charge slowly, it can also take a long time for them to charge. Another downside is that, over time, their ability to hold a charge decreases.
Within the category of portable jump starters, you also have two variations. Power packs are for smaller battery needs. They maintain a low charge over a longer period. Jumper packs are designed to “jump” in the sense that they create higher output, but for a short amount of time.
Both power packs and jumper packs can restart a discharged battery. However, the jumper pack will work better with a battery that is entirely dead or close to it.
If you’re looking for something to help your car battery recharge, you want to make sure that you are getting a car battery charger, not a car battery jump starter. Regardless of whether you need a battery charger or a jump starter, though, it’s essential to find an option that will work with your car battery’s voltage.
Most cars use a 12V battery, but some older models (and tractors) use a 6V battery. Many trucks’ batteries are 24V batteries.
Ultracapacitors – what are ultracapacitor jump starters?
The newest option on the market, ultra-capacitor jumper starters, offer a fast, lightweight, and portable option. Instead of traditional batteries, these jump starters use capacitors to store energy.
Unlike a battery, which utilizes chemical reactions to store energy, ultracapacitors use an electrostatic field. As a result, they are far more efficient but, more importantly, can charge off a smaller current, charge faster, and release energy faster.
These jump starters can use the residual energy in your battery to start your vehicle. They don’t need to be charged before use. Though, most models do offer the option to charge the unit via USB, a wall charger, or even a 12V auxiliary power outlet in your or another vehicle.
Now that we’ve covered some of the basic types of car battery jump starters, let’s take a look at the technology that’s inside of them.
What batteries are used in jump starters?
With the exception of ultra-capacitor jump starters, the technology inside of car battery booster packs begins with the batteries. There are two main types of batteries that you’ll find in car battery jump boxes—lead-acid batteries and lithium-ion.
Lead-acid batteries are similar to the battery inside of your car, while lithium-ion batteries are used in most smartphones and portable electronics. There are advantages and disadvantages to each that we will cover later.
If you’re working with just a standard car battery jump starter, you’ll have several other tech components aside from the battery. Today, many devices come with multiple safety features. Common safety features include a reset button, high-quality cables and clamps, and reverse-polarity protection.
What are some of the jump starter security features?
Reverse-polarity protection ensures that damage doesn’t occur if the power supply polarity is reversed. What this means, practically speaking, is that it’s there to help protect you and your vehicle in case of something serious going wrong. Reverse-polarity protection shuts off the power supply to minimize potential damage. It also helps protect from fire.
Quality cables and clamps are critical because they provide the connection between the battery booster and your car battery. Cables that are fraying or damaged should not be used.
Durable cables ensure safety and longevity. As the main point of contact, you want clamps that are safe as well. One thing to consider regarding the cables is the type of material used in their construction. Industrial-grade copper is always a good option.
Jumps starters – additional features
Many car battery jumpers boast multiple additions so that you get the most out of your purchase. Some technologies that you may find added to a car jump starter are air compressors, emergency lights, and power-inverter technology.
- Air compressors allow you to inflate a flat tire, which can be very useful–nobody likes to be stranded.
- Emergency lights are especially helpful if your car won’t start at night. Even if it isn’t night, emergency lights can still notify other drivers of your presence on the side of the road. Some car jump starters come with lights on the pack itself. Others have emergency lights on the cables that make it very easy to place the clamps in the correct spot if it is already dark or dim. Often emergency lights use LED bulbs that are highly energy efficient.
- Power-inverter technology allows for the current in the car battery booster pack to be converted from DC (direct current) to AC (alternating current). This ability enables you to use the battery jump starter to charge a phone or another device that uses USB charging. Some even have enough power to charge a laptop if you have the proper adapter to do so.
Car battery technology in-depth
Next, let’s take a more detailed look at the most important aspects of a car battery jumper, beginning with the battery types.
Lead-acid batteries have been around since the mid-1800s when Gaston Planté invented them. They are much less expensive than lithium-ion batteries and supply the high current required for car motors with ease. That’s why many cars are equipped with them.
Lead-acid batteries are composed of multiple cells that function by chemical reaction. Inside of the cells are sponge lead, lead peroxide, and dilute sulfuric acid. As the sulfuric acid dissolves, it breaks down positive hydrogen ions and negative sulfate ions.
More chemical reactions occur, and, in the end, the chemical energy becomes electrical energy via the thin plates inside of the battery (the interface between the electrodes and the electrolyte).
Lithium-ion batteries were developed more than 100 years after lead-acid batteries. They are tied directly to modern electronics and were a result of various researcher’s work between the 1970s and 1980s.
There are many different types of lithium-ion batteries, but most contain the same three essential components, one of which is always a variation of lithium. Pure lithium is highly reactive, and so the lithium inside of batteries is generally mixed with something else. Just like lead-acid batteries, lithium-ion batteries are made of electrodes and electrolytes.
Ultra-capacitors aren’t exactly a battery, but they can store energy like a battery. Sometimes called conductors, capacitors are common in computer components. They consist of two conductive materials separated by an insulator.
When exposed to energy, an electrical field forms across the insulator, and a charge builds on the conductors. While they can store more energy for a short time and charge/discharge faster, capacitors aren’t great for long-term storage. That’s why they aren’t used as batteries but work well for jumper starters where all that’s needed is a sudden jolt of energy to start the alternator.
Technical terms you may encounter when in buying a jump starter
The technical language used is part of the challenge as far as understanding how a car battery jump starter works. When you are looking at different car battery jump starters, the words used to refer to the battery’s power can range from joules to amps to amps per hour (AH).
Although these words are not interchangeable, the easiest measure to consider when you want a car battery jump starter is probably the CA rating and the CCA rating. CA rating is the cranking amps rating. Most four- or six-cylinder engines will require a minimum of 225 CAs.
The CCA rating stands for cold cranking rating and refers to how well the jump starter does in cold weather. Specifically, it measures the number of amps delivered by a 12V battery for 30 seconds when it is 0°F. The battery needs to produce at least a voltage of 7.5 while it does this.
If you live somewhere with harsh winters, you know that there’s a higher chance of your car battery needing a jump at some point during the winter months. You want a jump starter that’s able to withstand the cold temperatures and still provide an effective jumpstart to your dead car. For more details you can refer to our peak amps vs cranking apms guide.
What are the pros and cons of lead-acid car battery jump starters?
- Although their size profile has decreased over the years, car battery jump starters that have lead-acid batteries still tend to be significantly heavier and bulkier than other car battery boosters types. On the other hand, those with lead-acid batteries usually contain more power and are stronger than the others.
- If you have a car that requires a higher CA rating (cranking amps), you might want to lean toward a jump starter made with a lead-acid battery. Lead-acid batteries are often better for higher cylinder engines for this very reason.
- Typically, lead-acid batteries have a higher CCA rating as well. So, if you live in a colder climate or a place that has harsher winters, a lead-acid car battery jump starter is probably a better option for your needs.
- A disadvantage of these types of jump starters is that they do require more frequent monitoring to make sure that they remain charged. Additionally, the time needed to recharge a lead-acid battery is usually more extensive than what a lithium-ion battery requires.
What are the pros and cons of lithium-ion car battery jump starters?
- Car battery boosters using lithium-ion batteries frequently can provide multiple jumpstarts before they need to be recharged. They also tend to hold their charge for longer than lead-acid batteries do.
- Perhaps the second-best feature of car battery jump starters with lithium-ion batteries is how small and portable they are. Many of them fit inside a glove compartment or even a purse or backpack. That makes them the perfect tool for a motorist with a smaller vehicle such as a motorcycle.
- A slight disadvantage of car jump starters that use lithium-ion batteries is that they are not as powerful as the lead-acid variety. Lithium-ion batteries are also more sensitive to extreme temperatures.
- High heats and deep colds can reduce the longevity of a lithium-ion battery, meaning your car battery jump starter might not last as long if it’s using a lithium-ion battery.
Ultra-capacitor battery jump starters
Ultra-capacitor jump starters are very lightweight and easy to store in your vehicle as you don’t have to remember to charge them. Of all the car battery jumpers available, these are the most convenient—especially for emergency use away from home.
However, they may be ineffective if your battery is completely dead, and you don’t have an alternative energy source. They also don’t usually have accessory options and are the priciest of the three jumper types.
The different car accessories provide a lot of useful features for the average motorist. Sometimes instead of having multiple tools, just the one will do–this is a huge plus to consider. However, it is also critical to remember that each accessory technology, such as the compressor or the emergency LED lights, uses the car battery jump box.
Because they draw power, they will reduce the available charge if you end up needing the car battery jump box to jump your car. While some of the extra technologies provide valuable benefits in an emergency, it’s probably best not to use something like the inverter with regularity. After all, accessories won’t matter if you’re left without the ability to jumpstart your car if its battery dies.
Wrapping it up
Even though it seems like there are a lot of details to remember when you’re considering how a car battery jump starter works, the most important piece is really to look at your owner’s manual to make sure you match your vehicle’s requirements to the car battery booster pack that you’re considering.
The ideal car battery jump starter for your vehicle will vary based on its litres and the type of engine (diesel versus gas). Vehicles that require more power will need more powerful jump starters.
One crucial final thing to know is that you should never try to jumpstart an electric car. Their engineering is different, and a jumpstart could significantly damage the electronic components of the vehicle.
