portable power bank 3d model

Create a full 3D model of a sleek, futuristic portable power‑bank charger. Use a flat rectangular body about 60 mm long, 30 mm wide, and 12 mm thick, with rounded edges and a dark metallic or black finish. Add four fold‑out charging arms, one on each side of the device. Each arm should be about 6 mm thick and 25 mm long, with a smooth hinge where it connects to the body. At the ends of three arms, add realistic charging connectors: • One USB‑C connector • One Lightning connector • One Micro‑USB connector On the top surface, add a glowing blue tech panel. Above that, add a digital battery percentage display, like a small rectangular LED or OLED screen showing a number such as “87%”. Include a sliding compartment on the top or side of the device, shaped like a small box that stores magnetic charging tips.
