What Is a Jump Starter?

A car emergency starting power supply, also commonly known as a jump starter, is a power supply device designed to provide emergency power when the car battery is dead to help start the car engine. It is also called a car starting power supply or a car jumper power supply, and is one of the important auxiliary tools for driving. It is usually equipped with a high-capacity battery that can provide enough starting current for the car in a short time. It has the following main functions:

1) Emergency start car

2) As a power bank

3) Emergency lighting

4) Provide air pump function

Is it necessary to have a car jump starter? It is very necessary, the following are the main reasons:

Dealing with battery problems: Car batteries may not be able to start the vehicle due to low temperature, aging or long-term non-use. The emergency starting power supply can provide a convenient starting solution to avoid waiting for external rescue.

Good for remote driving: In remote or sparsely populated areas, finding help may be difficult, and having an emergency power source can provide an extra layer of safety.

Multifunctional use: Many modern car emergency power banks can not only start the vehicle, but also charge mobile phones, tablets and other devices. Some are also equipped with practical functions such as LED lights, SOS signals, air pumps, etc., which are very suitable for travel or emergencies.

Save time and money: Using emergency power can avoid calling roadside assistance, saving time and possible expenses.

Easy to operate: Modern car emergency power supplies are usually designed to be simple and easy to use, even non-professionals can easily operate them.

Adapt to special environments: In winter or extreme weather, car batteries are prone to failure. The emergency starting power supply can provide enough power for the engine to restart the vehicle.

How to choose a suitable car jump starter?

Car jump starters are mainly divided into two types: lead-acid batteries and lithium polymer batteries. Lithium polymer batteries are more recommended here because they are usually lighter, smaller, and provide stable performance. In addition, choose the right voltage according to the model. Usually, family cars and motorcycles are mostly 12V, while large trucks or buses are 24V. The number of cells should preferably be 4 cells in series, as well as high-quality high-rate cells. I recommend our YD products. Car jump starter and air compressor has good quality and super high cost performance, and has relatively complete functions.

In short, as a portable, safe and reliable car jump starter device, it is a wise choice to buy a car emergency starting power supply considering its practicality and importance. It can provide protection for your travel at critical moments, making your journey more secure and smooth.
