Belkin Global Travel Kit 2.4amp Single Port USB Charger - White $19 @ Harvey Norman
I noticed this come up on price hipster. 2.4A interchangeable plug formats including AU, UK, US, EU, KR, and China.
Seems like a good price for a Belkin if your not into the Chinese branded gear for fear of your house burning down and your non-existent insurance being denied.
If you have ebay plus its available for an extra 99 cents delivered.
