Does the emergency power supply of the car damage the car?

Nowadays, in the environment where cars are popular everywhere, cars have become an indispensable means of transportation; but when you start the car in the early morning or encounter some accidents during the driving, such as the long-distance driving, the car battery runs out, what should I do? This time Many of our drivers would think of using a car to start the power supply, but many people do not understand why a small car emergency start power supply can start the car? Will the car emergency start power supply damage the car? Why can the small car emergency start power supply start the car? The main job of the car emergency power supply is to start the car's ignition power supply device for a short time when the car battery is dead or dead and cannot be started. The car needs a lot of current to start, and the limited voltage must be instantaneously turned into a strong current through the relay and supplied to the starter. When the battery is out of power, connecting the car's emergency starting power supply is equivalent to connecting a 12V battery to a 12V battery. However, the electric capacity of the car emergency power supply is limited, and each start cannot be too long, and it is not possible to take a taxi continuously without interval, otherwise the power supply will also lose electricity. Will the car's emergency starting power supply damage the car? Let's take a look at the operating instructions of the car's emergency starting power supply. 1. Pull up the manual brake, place the clutch in neutral, and check the starter switch. It should be in the OFF position. 2. Please place the emergency starter on a stable ground or a non-moving platform, away from the engine and belts. 3. Connect the red positive clip (+) of the 'emergency starter' to the positive electrode of the battery that lacks power. And make sure the connection is firm. 4. Connect the black accessory clip (-) of the 'emergency starter' to the grounding pole of the car, and make sure the connection is firm. 5. Check the correctness and firmness of the connection. 6. Start the car (no more than 5 seconds). If a start is not successful, please wait for more than 5 seconds. 7. After success, remove the negative clamp from the grounding pole. 8. Remove the red positive clip of the 'emergency starter' from the positive pole of the battery. 9. Please charge the battery after use. The car's emergency starting power supply, as the name suggests, is for emergency use, but if it is used improperly, it will also cause damage to the car. Users must pay attention to this point. The primary problem of improper use is that the positive and negative polarities are reversed when connecting with the car circuit, which will cause damage to many circuit components without protective measures. The original design principle of the emergency power supply is to output a high-power 12V DC current to assist the car to start and maintain the entire car's electricity in a short time when the car battery is fed. The battery feed failure should be analyzed and resolved by finding the cause of the failure. You can't always rely on the emergency power supply to start the vehicle. If you operate in the correct way, the emergency power supply will not do any harm to the car, so you can use it with confidence.
