Visual first Iimpression thread: What exterior detail makes you stop and check a power bank?

Hey everyone, today’s discussion topic:

When you’re checking out a new power bank, what’s the first exterior detail that catches your attention?

Is it the overall design, the size, the thickness, the texture, the display, the placement of ports, the color or something else? Let us know in the comments, what’s one visual feature on a power bank that makes you think, “okay, I want to know more about this”?
