Xiaomi Power Bank 3 Product Hero Image

[Format] Professional e-commerce product main image, square 1:1, clean tech-promo style built on one bold flat colour field. [Colors] Background a saturated orange gradient (#f2760f to #ff9a2e range) deepening toward the corners; white and metallic gold as secondary accents; a pale silver-grey floor sweep at the bottom; crisp white type throughout; no frame border. [Layout] The headline occupies the upper-left half; a vertical list of three feature rows runs beneath it; the two hero power banks stand side by side on the right half, meeting a soft reflective floor at the bottom edge. [Subject] No people. Two slim anodized-aluminium power banks, one gold and one ice-blue, standing upright at a slight inward angle with softly rounded corners, white top caps and USB ports visible along their edges, mirrored in a gentle floor reflection. [Headline] Upper left in heavy white sans-serif on two lines: "Xiaomi Power Bank 3" then "20000mAh". Below, three icon rows in white with small circular glyphs: "18W two-way fast charging", "Sleek minimal design" and "USB-C fast-charge output". [Badges] None beyond the three feature rows. [Mood] Bright, confident and specification-led; one vivid orange field with crisp white type and a clean product hero.
