well... why would they have asked about travel and mentioned the 120-240
switch? (assuming 110/120 V service and a switch - it wasn't clear if they
meant that the converter said "120/240 input" or was a switch) besides, it
doesn't hurt to give more info than they need. Some laptop power converters
(and "other" converters as well - my NiMH camera battery charger as an
example) use BOTH without needing to switch a switch - just plug it in and
it works. Since laptops on external power STILL utilise the battery as
primary power source (the converter acts as a charger and supplements the
battery) there might be a voltage lock built in to the charger/converter and
no switching necessary. IF that's the case, then all they need is a power
adapter plug.

just a cable with the proper ends (the power supply input is standard
and
you can buy an adapter to make the US style cable fit ....

and what if she has a normal laptop (with a non-US plug) ?
She is probably living in Europe or Asia...
