The smaller one is the size of a cigarette pack. It has a stylish and lightweight appearance. It is very suitable for teachers, teachers and tour guides. It can be hung around the waist to free your hands and play more freely. To the praise of the industry, the power hung around the waist is 3W-8W. The large size is suitable for outdoor activities, summer camps, extracurricular lectures and other places with high traffic. The power is 35W---95W.
