What is a jump pack?

A jump pack, often referred to as a jump starter or battery booster, is a portable device that provides the necessary power to start a vehicle with a depleted battery. Unlike traditional jumper cables, a jump pack doesn’t require another vehicle to source the power from. It’s essentially a battery in a box, equipped with its own set of cables and clamps to connect to your car’s battery. These devices are not only compact and easy to store but also come with various safety features to protect both the user and the vehicle’s electrical system.

The primary function of a jump pack is to deliver a powerful electrical charge to a vehicle’s dead battery, providing it with enough energy to start the engine. When the jump pack’s cables are connected to the correct battery terminals, it transfers power to the battery, mimicking the electrical input that would normally come from an alternator in a running vehicle. Many jump packs also come with additional features such as USB ports for charging mobile devices, emergency lights, and even air compressors, making them versatile tools for various emergencies.

Choosing the right jump pack involves considering several factors. First, you need to look at the size of the engine you intend to jump-start. Diesel engines, for example, require more power to start than gasoline engines. Therefore, a jump pack with a higher peak amp rating is necessary for larger or diesel engines. Secondly, consider the size and weight of the jump pack. If you have limited storage space or find heavy lifting challenging, a compact, lightweight model might be best for you. Lastly, check for additional features that could be beneficial, such as built-in safety protections against overcharging or short-circuiting, and extra functionalities like LED lights or power outlets.

The lifespan of a jump pack can vary significantly based on its construction, usage, and maintenance. Generally, a well-maintained jump pack can last for several years. The battery inside the jump pack, usually a lithium-ion or lead-acid type, has a finite number of charge cycles it can go through before its capacity begins to degrade. Proper care, such as storing the jump pack in a cool, dry place and keeping it charged, can extend its useful life. Additionally, using the jump pack within its intended capacity and avoiding deep discharges can also prolong its lifespan.

Replacing a jump pack typically involves purchasing a new unit, as the internal batteries are not designed to be user-replaceable. When choosing a replacement, consider the lessons learned from your previous jump pack. Perhaps you need a model with a higher power output, or maybe additional features like a USB port would be beneficial. Always dispose of the old jump pack properly, following local regulations for battery disposal, to minimize environmental impact.

The cost of jump packs can vary widely based on their power output, size, and additional features. Basic models suitable for small to medium-sized gasoline engines might start around $50, while more powerful versions designed for larger or diesel engines can cost $150 or more. Models with extra features like air compressors, USB charging ports, and high-intensity lights can command higher prices. When considering the cost, think about the value of being self-reliant in the event of a dead battery and the convenience of having additional portable power sources for emergencies.


A jump pack is an invaluable tool for any vehicle owner, providing peace of mind and convenience in the event of a dead battery. By understanding what a jump pack is, how it works, and how to choose the right one for your needs, you can ensure that you’re always prepared, no matter where your travels take you. Remember, the best jump pack is the one that fits your specific requirements, from engine size to additional features, ensuring that you’re never left stranded.
