The lead-acid battery type automobile emergency starting power supply is more traditional, and the maintenance-free lead-acid battery is used, which is larger in mass and volume, and the corresponding battery capacity and starting current are also relatively large. Such products are generally equipped with an air pump, and 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.
Lithium polymer emergency starting power supplies for automobiles are relatively trendy. It is a product that has appeared recently. It is light in weight and compact in size and can be controlled with one hand. This kind of product is generally not equipped with an air pump, has an overcharge shutdown function, and has a relatively powerful lighting function, which can supply power for various electronic products. The lighting of this type of product generally has the function of flashing or SOS remote LED rescue signal light, which is more practical.
