Description

Technical Field

[0001] The utility model relates to the field of mobile power supplies, in particular to a mobile power supply with an adapter function. Background Art

[0002] With the development of smart phone technology, the screens of smart phones are getting bigger, the functions are increasing, and the hardware configuration is getting higher. Although the user experience is greatly improved, the accompanying defect of fast power consumption of mobile phones is becoming more and more prominent. Especially when there is no power supply when going out, it will bring great inconvenience if the mobile phone is out of power. Mobile power (power bank) came into being to solve the problem of no power supply when going out, and it is loved by the public.

[0003] A mobile power bank is a portable power bank with large capacity and is easy to carry. It is a portable device that integrates power storage, voltage boosting, and charging management. However, the power storage capacity of a mobile power bank is not unlimited. For some users, they are still worried about insufficient power in their mobile phones. At the same time, for some power-intensive products (such as tablets), the power storage capacity of the mobile power bank cannot power them for a long time. Therefore, in order to further solve the problem, these users often carry a power adapter when going out, so that they can find a socket as soon as possible to charge when the mobile power bank is out of power. However, carrying an adapter and a mobile power bank at the same time will undoubtedly bring a burden to users when going out.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
