Photograph of a sleek, silver, rectangular power bank with a USB-C port and cable, partially embedded in a cluster of translucent, jagged ice crystals. The power bank displays "10000mAh" in black text on its back. The icy background features a serene, snowy landscape with distant, snow-capped mountains under a clear, blue sky. The ice crystals have a glossy texture, reflecting light, and the power bank has a smooth, matte finish. The overall color palette is cool, with shades of blue, white, and silver dominating the image. The scene evokes a sense of cold, winter wilderness.
