Which car emergency power supply is good? What are the characteristics of portable car starter battery and lithium polymer batteries?
The traditional lead-acid battery type of automotive emergency starting power supply uses a maintenance-free lead-acid battery, which has a large mass and volume, and the corresponding battery capacity and starting current will also be relatively large.
However, the emergency starting power source of the car is a lithium polymer battery, which is easy to operate, easy to carry, small in size and light in weight.
Lithium polymer batteries also have functions such as overcurrent, overload, overcharge and reverse connection indication protection, which can charge various electronic products, and some products also have functions such as inverters.
