Description

an external charger

technical field

The utility model relates to an external charger, more specifically, the utility model relates to a portable external charger using solar energy.

Background technique

With the development of science and technology, more and more electrical appliances have become miniaturized and portable. People often carry many portable electronic products when they go out, such as mobile phones, walkmans, laptops and the like. However, the development of batteries cannot keep up with the pace of development of portable electronic products. Many portable electronic products consume more and more power. When the battery is exhausted, it brings a lot of trouble to people, especially mobile phones. Finally, people will miss calls, causing a lot of unnecessary trouble and loss.

The periphery of the LED lamp is provided with a reflective lampshade, and the reflective lampshade is covered with lampshade glass.

The two ends of the wristband are connected by Velcro.

Beneficial technical effects brought by the utility model:

1. The solar function design is energy-saving, environmentally friendly and pollution-free. It is aimed at outdoor sports enthusiasts. It has a stylish appearance and a wristband design that is easy to carry outdoors and is not easy to lose;

2. It is equipped with a solar charging board, which can be continuously charged outdoors, so that the capacity of the battery can be made very small, so that the volume of the entire charger is reduced and it is easy to carry;

3. Using solar energy to charge, it can be charged continuously, which saves time and energy;

4. Set up LED lights and add new functions. It can be used as a flashlight at night and in dark places, which improves the utilization rate of electric energy;

5. The shell is divided into upper and lower parts, and is connected with the buckle plate, which is convenient for quick disassembly, maintenance and battery replacement, and this makes the whole body very firm and not easy to break;

6. Both ends of the buckle plate are sloped, and there is a groove in the middle, so that the buckle can be removed with a small force, which is convenient for disassembly.
