I did just this, buy locally, for a US 110volt device imported to
Australia some years ago.

The best thing is for the customer to take the requirements to a
supplier in China, afterall most wallwarts I see in Australia these days
are made in China.

Letting him purchase locally has several advantages, shipping weight of
course, correct wall plug and importantly (maybe not in China) the
device he buys locally will conform to code requirements in that
country. Even if your 110volt wall wart could be supplied from a
transformer it may not conform and if anything ever went wrong Well!!
