Problems solved by technology
[0003] Ordinary batteries are not only heavy and bulky, it is inconvenient to install on the car body or carry them with you
Moreover, ordinary users are not familiar with the connection method of wires. When using a battery with a large output power, if it is connected incorrectly, it may damage the electrical appliance, and it is easy to cause problems with the battery. The safety is not high, let alone the first aid effect.

Description
technical field [0001] The invention relates to a portable music emergency power supply device, in particular to a multifunctional portable music emergency power supply device which can be used for fast charging of automobiles and motorcycles. Background technique [0002] With the advancement of technology, more and more people use electronic products, so when the power of the electronic products is low, an auxiliary power supply is needed to provide appropriate power to maintain the continuous use of the electronic devices. At present, in addition to the general portable small power supply that can be used for charging electronic products, the power supply device that needs a larger output power can only rely on the storage battery. [0003] General batteries are not only heavy, but also bulky, making it inconvenient to install on the vehicle body or carry them with you. Moreover, ordinary users are not familiar with the connection method of wires. When using a battery wi...
