Reply to Laptop performance under international power adaptor charge

Ahoy mateys,
I was wondering if there is any potential risks or complications to my laptops performance if i was to always use a internation power adaptor? I live in Australia and I'm looking at getting a Dell Alienware laptop sent from the US and thought I would run it past this cluey bunch on djranking s. If it is risky, would it be posible to buy an Australian charger instead and still function properly?
It may seem like a silly question- as I'm sure touring artists perform like this all the time- but always nice to be-sure.

The laptop will usually Dj serato itch or perform live with Ableton oth through the Novation Itch.

Many thanks
Ding
