power bank 3d model

Create a realistic, presentation-ready 3D model of a portable power bank designed for a campus rental system. The power bank should be slim and rectangular with softly rounded edges and a minimal, durable design suitable for frequent student use. It should appear compact and easy to hold in one hand. Include a single small LED indicator on the front to show charge status. One USB-C output port should be clearly visible on one side, with no additional ports. The surface material should look like matte plastic or anodized metal to resist fingerprints and scratches, using neutral colors such as dark grey or black with a subtle green accent to match an eco-friendly theme. Avoid logos, text, or complex markings. The style should be realistic and practical rather than futuristic, with medium detail, clean geometry, no visible internal components, no cables, no people, and no environment, presented in a neutral studio view suitable for basic animation and insertion into a rental station model
