Let's leave USB for the computers and microelectronics. I can still charge electric trimmers and toothbrush when there's oil/water/toothpaste on or even in the port. It also still trivially easy to break a usb port. On devices with the rubber power connector you can practically bend the plug out sideways without damage. They're also much easier to connect as they're not designed to support 10+Gbit/s of signal integrity.

I believe a sufficiently motivated market would come up with a good solution. I just don't believe every small device in my house needs its own proprietary charging tech.

My toothbrush is induction charged, this is the way.
