I am not sure if the product has a brand equity value to itself, especially for power banks. The barriers to entry is low for such accessories. I've been noticing that a lot of people are giving out power banks as freebies and I myself have received a power bank which was a "built-to-order" by a colleague of mine. So, to get someone to manufacture power banks and then re-sell it is not difficult.
