Australia to United States: Complete Plug & Adapter Guide (2026) Adapter Needed

Traveling from Australia to United States means crossing into a different electrical system. Before you leave, take a moment to understand the plug types and voltage used in United States so you can keep all your devices charged and ready.

There's no plug compatibility between Australia and United States. Australia devices use Type I connectors, while United States sockets are Type A/B. An adapter is a must-have for this destination.

Voltage is another key difference. Australia uses 230V while United States uses 120V. If your device only supports one voltage, using it with the wrong supply could cause overheating or permanent damage. Look for "Input: 100-240V" on your charger. Most modern phone and laptop chargers support this range.

When packing for United States, bring at least one adapter per room if you're traveling with others. Airport shops often sell them at a markup, so ordering one online beforehand saves money. A small power strip from home can also multiply a single adapter into several outlets.
