Description

A power supply box with a display screen

technical field

The utility model relates to a power supply, in particular to a power supply box with a display screen.

Background technique

With the development of science and technology and the improvement of people's living standards, mobile phones, PDAs, digital cameras, MP3, MP4 and other portable electronic products are increasingly used in people's lives, and even become an indispensable part of people's daily life. The use of portable electronic products is generally provided by batteries. Due to the limited power storage capacity of batteries, after a certain period of use, the battery power will be exhausted. At this time, it is necessary to replace the battery or use a charger to charge the secondary battery. Most of the traditional chargers use the mains (AC100V-240V) as the charging power source to charge the secondary battery, which brings inconvenience to people when they work in the field for a long time or travel outdoors when using electronic products. In order to overcome this defect, more and more solar chargers using solar energy as a charging source have appeared. This type of charger can either convert solar energy into electrical energy to directly supply external power, or convert solar energy into electrical energy and store it. It also retains the characteristic that the traditional charger can directly use the mains or external power supply equipment for charging, which better meets the different needs of users. However, there are still deficiencies in this type of charger, such as the inability to intuitively understand the working status of the charger, resulting in inadequate monitoring and adjustment, and potential safety hazards in use.
