At the risk of derailing this topic (I'll split it off if there's any further discussion generated) - in unknown locations I totally agree (Unless you've jailbroken the device, both recent versions of Android and iOS will ask for permission to share data with anything you plug into but its a very easy prompt to miss, with no confirmation prompt), but in chain hotels I think this is less of an issue, their USB sockets will pretty much always just be a module ultimately linked into the same power source as the nearby 3-pin plugs. I do tend to use my 3 pin to USB converter but that's more to do with charge speed than any security risk.
The biggest risk if there was a computer at the other end trying to send data that's trying to trigger a response back from your device would be connecting a laptop, and most of these aren't powered by USB (at least not at the typical 5v voltage a standard bedside USB outlet will provide).
If you want to be really paranoid about it but still use random USB charge ports then the simplest solution is to use a cable that is incapable of data transfer. Some of the cheapo ones I have seem to come pre-installed with this "security feature".
