Use the supplied reference image as the sole locked product input. Preserve the product's exact appearance, structure, materials, colors, proportions, logo, label, accessories, and product-set relationship.
Create a 1:1 photorealistic commercial product poster. Balance the single slim white-and-blue power bank diagonally on the edge of a pale concrete ledge. Use a clear blue sky, a long sharp shadow, and clean minimalist outdoor light.
Use a polished premium advertising finish with crisp product focus, coherent perspective, realistic materials, controlled depth of field, and physically plausible lighting. Keep all decorative elements physically plausible and subordinate to the product. Keep existing product text legible when present. No poster text, watermark, extra product, unrelated logo, distorted object, changed product appearance, or unnecessary person.
