Do I need a special Adaptor plug to use my electrical equipment in the USA
Hi Lynda - they are different plugs and voltage.
USA is 110V and Australia is 230V. The wall sockets are different, so you'll need an adapter, and be sure that any device you plug in is rated for 110V. For example, Apple laptop adapters work for both 110V and 230V - it should say the ratings on any device you use. about 10 years ago
