All "travel adapters" (power outlet adapters) I've come across so far
had no earthing so would be impossible to use (unaltered). Of course
this wouldn't be much of a change as the current wall warts also don't
fit any adapter I've seen at shops. At SugarCamp in Paris, quite a few
people (including myself) had "custom" ones, i.e. with mechanic
Personally, I feel comfortable making minor mechanic changes to an
adapter, but I won't usually dare using a non-earthing adapter with a
device having an earthed plug (unless I know for sure this is safe).
Actually, if you are able to use a standard plug (e.g. IEC-60320-C5/C6)
at the power supply end, above won't apply at all as it's usually easy
to get a matching cable, no travel adapter needed. :)
I hope future XO versions will still have the same broad power input
specs as the XO-1. It's been very useful already (e.g. cable-only "car
adapter", no voltage conversion or even voltage limit necessary).
