Why Can the Emergency Starting Power Start the Car?

Why Can the Emergency Starting Power Start the Car?

At present, this kind of product is called "emergency starting power for automobile", which can also be regarded as a function expansion version of the power bank. It has no difference between the appearance and the power bank, and its capacity is not particularly exaggerated. The battery capacity of the product we are trying is 12V 12000mah, which can provide more output current compared with the ordinary power bank, which is generally 1a and 2.1a.

Generally speaking, the instantaneous current of the electric appliance when it is started is much larger than the normal working current. The instantaneous current of the car when it is started will be more than 200 amperes. The general charger can't bear such a large current. In addition, there is no interface for matching wires, and the emergency starting power of the car can support the maximum current of 200a-400a. It's not the most conventional 18650 battery, but a larger lithium battery. Its name is "high power polymer cell". The wire of the special interface for starting the car is much thicker than other lines. It is the basis for bearing large current, which is also an important difference from the ordinary power bank.

1. How many times can the vehicle be started continuously with a full charge?
Within a few days after the trial use of the emergency starting power of the vehicle, we respectively used it to start the three displacement models (1.3L, 1.6L, 2.4L) with full charge, and started 10 times in total, leaving half of the power without recharging. Relevant information also shows that for the mass displacement between 1.0l-4.0l, the vehicle can be started about 10-15 times after being fully charged.

2. Is there a limit to the engine?
For engines under 4.0L (or 8 cylinders), this product can basically cope with it. However, the larger the engine displacement is, the more cylinders there are, the greater the kinetic energy required for starting, and the instantaneous starting current may soar to a higher level. Before using, try to determine whether the product can support the corresponding current.

Advantages over traditional patch cords: no need for other vehicles / convenient storage

For the matter of vehicle power failure rescue, if it's a manual car, it's better. You can use the original cart method to solve it, while the automatic car can only be powered up for rescue. If you can't find the second car for assistance at this time, you can really die in a hurry. The car emergency starting power can solve the need of independent rescue. The other biggest advantage is that the power supply volume is equivalent to the power bank, which is much smaller than the volume of the traditional cable set. In addition, the battery clamp weighs only about 1 jin, which is also very convenient to store.
