Description
Technical Field
[0001] The utility model belongs to the technical field of power supply, and in particular relates to a manually switched dual-purpose mobile power supply having both the functions of automobile emergency starting and power bank. Background Art
[0002] Drivers and vehicle rescue personnel usually carry an emergency starting power supply in their vehicles, and also carry a power bank to charge mobile phones and other mobile terminals.
[0003] Starting a vehicle generally requires a power supply of 12V, 100A-300A, but the voltage of a single battery cell cannot meet the requirements. Therefore, the usual practice of portable car emergency starting power supplies is to connect multiple high-rate batteries in series to boost the voltage to 12V or above. The capacity after series connection is still the same as the capacity of a single battery cell. For example, if three 4.2V4000mAh batteries are connected in series, the voltage rises to 12.6V, but the capacity is still 4000mAh. However, the car emergency starting power supply is a tool that is used very infrequently, which leads to a large amount of battery waste. At the same time, users need to buy an extra power bank, which not only seriously wastes resources but also increases the user's investment cost. Utility Model Content
