As usual. Fear = more viewers = more ad revenue
Current versions of iOS won't allow USB communication with a device you haven't explicitly authorized, and will require you to unlock your phone if it has been locked for more than an hour (by default at least). I think Android has similar restrictions.
If you're still worried, just use a regular outlet to charge with a charger you bring. I do that anyway, since many public USB ports may not provide the full 2A that the phone can take...and newer phones can take even more with the correct charger.
