Something about water having a high resistance so that only high voltage power will jump across it... Anyway, as far as I know USB power should work perfectly fine fully submerged without any waterproofing.

But you might run into problems with vibration and rust depending on how well it is made.

Very true, PURE water doesn't conduct electricity. If you get rained on, somewhere that rain doesn't have a ph of 5 due to pollutants, you will be fine.

For those of us near salt water it is another story entirely. One of the 'gold' pins on my Garmin 60CSx departed recently but I did get 6 years use from it, much of that on or near the ocean. USB connections (to my knowledge) don't have more than chrome for protection, I am betting they last more like 6 months.

No one calls the Fire Department because they did something smart!
