Here is my spin on a power bank, one that looks like an old-school Operation board game. His nose is now an indicator light to show when a device is charging, and the surgery cavities are now cable ports. There are extra USB ports in the base.
I updated the character (who is known as Cavity Sam) to wear boxer shorts and have a more relaxed pose, which echos what Hasbro has done with their official game in the past dozen or so years. That dude looks too chill.
I’ll have a few more power bank designs posted in the coming days, stay tuned for those.
