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.
Another awesome design!
This is sweet
