3-4 design concepts for Powerbank packaging

I need a very quick turnaround (1 day). Looking for a graphic designer to design 3 concepts for a Powerbank packaging. Die lines are provided. I need bold colourful/contrasting packaging concepts that will stand out from other power banks on the shelf, so you'll have to think outside of the box. Please provide examples of previous packaging designs, preferably in the tech department. I've attached some inspiration of what we're looking for. The power banks are pastel yellow, green, red, white, gray, black.
