A jump starter is mainly used to transfer power when the car battery is dead. It allows the battery to be charged and brought back into working condition. It is important to have one in any car because it can help you get out of a difficult situation.

Some car enthusiasts who do not have wires remove their batteries, replace them with accumulators or other donor devices from other cars, after charging which the engine starts. After that, it is possible to install a standard battery, but this is a very dangerous operation.

How to choose a terminal block extender?

It is important that the extension cord you choose is of high quality, because as you know, it performs a very important job and it is important that it transmits electrical energy well.

The resistance depends on the diameter of the cable. A wire that is too thin will not be enough to start the engine. The minimum is 6 mm, which is suitable for cars with small engines (up to 1.5 liters), and the best option would be a version with a diameter of 9-12 mm.
The length of the wire also affects durability. It is advisable to choose a cable between 2.5-4 meters long, which is not too short to reach another car, and not so long that it negatively affects the transfer of power from one battery to another.
Wire and clamp material - they should be made of copper, as it has the lowest resistance compared to other materials. The protection should be made of silicone or frost-resistant rubber to withstand environmental influences.
Temperature changes can cause the cable to change its flexibility, so attention should be paid to the strength of the insulation. The terminals should be at least copper-plated.

The cable connection to the clamps must be very well-made, as this is usually the most vulnerable place. A poor connection will cause voltage loss, which is not good for cars.
Two-color wires - necessary for the convenience of connection and to ensure the safety of drivers, so as not to confuse the connection order. Traditionally, the positive wire is red, and the negative is black.
