International Travel Electrical Guides

You will need a Type G plug adapter to fit American Type A/B plugs into British three-pronged sockets. Furthermore, because the UK operates on 230V (compared to 120V in the US), single-voltage heating appliances like curling irons and hair dryers will require a step-down voltage converter.

Most two-prong US (Type A) plugs physically fit into Japanese wall outlets without an adapter. However, three-prong US plugs (Type B) will NOT fit into most Japanese hotel sockets without a 3-to-2 prong grounding adapter, as Japanese residential outlets rarely have an earth hole.

Traveling to France requires a Type C (Europlug) or Type E plug adapter. France operates on 230V at 50Hz, meaning US 120V devices must support dual voltage or be powered through a step-down transformer.

Italy primarily uses Type C (two round pins) and Type L (three round pins in a row), with German Schuko (Type F) becoming common in modern hotels. US travelers need a Type C or Type L adapter and dual-voltage-compatible devices for Italy's 230V power.

You will need a Type A or grounded Type B adapter to plug UK three-pin plugs into American two- or three-pin sockets. The US electrical grid operates at 120V at 60Hz, compared to the UK's 230V at 50Hz.

Good news: Australia and the United Kingdom share the same electrical grid voltage (230V) and frequency (50Hz). This means you do NOT need a voltage converter for any appliance—you only need a simple mechanical Type I to Type G plug adapter.

In Bali and across Indonesia, sockets are standard European round-pin Type C and Schuko Type F. The voltage is 230V at 50Hz, so US travelers need a Type C/F adapter and dual-voltage electronics.
