The appearance design of this self-belt charging treasure takes "portable and practical minimalist aesthetics" as the core, and adapts to different style requirements through rich color selection.

1. overall shape and color scheme
Outline design: the use of round oval cake shape, soft lines without edges, not only to avoid the daily collision damage, but also to make the grip feel more comfortable. The thickness of the body is only about 15mm, the size is small and light, and it can be easily put into a pocket or a small bag, which is fully suitable for portable scenes such as commuting and outdoor.
Color selection: the basic model is matte black, low-key stain-resistant, matte texture is high and not easy to leave fingerprints. The fashion style provides three color matching of gradual gray, gradual red and gradual blue. The color transition from light to dark enhances the visual layering. The color of the lanyard fully corresponds to the gradual color of the body, and the overall style is more unified.

2. Front Texture Design
The front is the iconic concentric circular corrugated texture, and the arc-shaped lines spreading from the center to the outside not only enhance the visual layering, but also increase the friction force, play a non-slip effect, and make the grip more stable.
The central area is printed with the brand logo, which is printed in matte silver with the same color as the fuselage. It is low-key and not abrupt, which not only strengthens the brand recognition, but also does not destroy the overall minimalist style.

3. functional detail design
Self-contained hidden charging line: the side is designed with a Type-C charging line that can be stored, which is usually hidden in the groove of the body and can be pulled out directly during use, thus avoiding the problems of wire winding and loss and making emergency charging more convenient.
Portable braided lanyard: The top is equipped with a high-toughness braided lanyard, which is made of wear-resistant and anti-building materials and can be easily hung on backpacks and mountaineering buckles. It is suitable for many scenes such as commuting and outdoor. The joint between the lanyard and the fuselage is reinforced with stronger durability.
Interface and status prompt: the Type-C charging interface can be seen on the top edge, and the indicator light is provided beside the interface, which can visually display the charging status (such as charging and full charge); The round solid button on the side can be pressed lightly to display the power generation, and the operation logic is simple.

4. material and texture
The body shell is made of high toughness ABS PC plastic, which is both portable and anti-falling, and can cope with daily bumps and outdoor environment wear.
The matte coating on the surface is delicate to the touch, and the concentric ripples bring rich texture changes, making the simple appearance more detailed and improving the comfort of holding.
