Outdoor portable mobile power supply is a portable charger that integrates outdoor power supply and charging functions. It is an integration of the charger and battery, and can charge or standby power digital devices such as mobile phones anytime, anywhere. Generally, lithium cells or dry batteries are used as storage units. Different from the batteries configured internally in the product, also known as external batteries or external batteries. Generally equipped with multiple power adapters, it is characterized by large capacity, multi-purpose, small size, long service life, and safety and reliability. It is a functional product that can provide power or standby charging for various digital products such as mobile phones, PDAs, laptops, etc. anytime and anywhere.

        With the rapid development of the global economy and the continuous improvement of people's living standards, there are more and more portable electronic products. Most of them require batteries, but the original batteries of these devices may not meet the normal usage time of the devices due to their low battery capacity. When traveling or on business, it is the peak period for these devices to work, often with the battery running out at critical moments. Based on this, mobile power applications have emerged. With mobile power, it can solve the power supply problem of many mobile devices, completely solving the problem of power shortage and making work and travel carefree.
