How to choose a car emergency starting power supply?best batteries for off grid solar

　　The main components of the automotive emergency startup power supply are: high -magnification lithium batteries, intelligent control systems, ABS fire heat -resistant shells. Selecting a car emergency startup to see its corresponding safety, circuit board, real battery capacity, and protecting the shell.

　　1. Security

　　Safety is one of the most important factor in all electronic products that cannot be ignored. The battery cell is an important part of the automotive emergency starting power supply. It can be said that it is the core part of the entire automotive emergency starting power supply. Therefore, the quality of the battery is one aspect of the quality of the emergency vehicle jump starter. We can mainly judge its quality through capacity, working voltage, charging and discharge cycle life. The cells used by the car emergency starting power supply are high -power cells, and the high -power cells determine the quality and safety of the product. Some cottage products use the B -quality core or refurbish the battery cells in a secondary charging, which severely shorten the life life of the product, and even excessive use causes the battery to expand and fire, which can easily cause safety accidents

　　2. Circuit board

　　We know that when the power supply to the car emergency power supply is connected through the circuit board and the wire, the quality of the intelligent control system also determines the quality and safety of the product. Therefore, while distinguishing the quality of the vehicle's emergency starting power supply, we must also pay attention to the selection of the circuit board. Using inferior circuit board (intelligent control system), it cannot give the product corresponding protection; automotive emergency starting power supply is a tool that accompanies the entire life process of the car, and the internal environment of the car is sometimes bad, such as extremely high temperature and low temperature, strenuous bumps. Wet or dry, which also puts forward high requirements for the manufacturing level of automotive emergency power supply.

　　3. Real battery capacity

　　The car emergency startup power supply is essentially a mobile power supply, and a key indicator of measuring whether the mobile power supply is excellent is its real battery capacity. Many domestic battery manufacturers have a more serious problem, that is, the virtual capacity is more serious. Car emergency startup power capacity on the market is mainly 100,000mAh/12000mAh/16000mAh/20000mAh. This is a common standard on the market. Another key indicator of measuring whether the automotive emergency starting power supply is excellent is whether its self -consuming consumption is low. There is no electricity in a product in a month without charging and 80%of the electricity for half a year. This riders know clearly.
