Japan
100V · 50Hz (East) / 60Hz (West)
Type A
Type BJapan uses Type A and Type B outlets with 100V electricity. If you are traveling from the US or Canada, your standard two-prong plugs (Type A) fit Japanese outlets without any adapter. Three-prong plugs need a simple grounding adapter. Travelers from the UK, Europe, Australia, and most of Asia will need a travel adapter. The good news: Japan's 100V power is close enough to 120V that most dual-voltage electronics (phones, laptops, cameras) work without a converter.

United Kingdom
230V · 50Hz
Type GThe United Kingdom uses Type G outlets exclusively. These are the large three-rectangular-pin plugs found nowhere else in mainland Europe. Every traveler from the US, Europe, Australia, and Asia needs a travel adapter. The UK runs on 230V at 50Hz, which is standard for most of the world outside the Americas. Your phone and laptop chargers are almost certainly dual voltage and only need a plug adapter, not a voltage converter.

Australia
230V · 50Hz
Type IAustralia uses Type I outlets (two angled flat pins plus a grounding pin) with 230V electricity at 50Hz. Travelers from the US, UK, Europe, and most of Asia all need a travel adapter. Your phone, laptop, and camera chargers are dual voltage (100-240V) and only need a plug adapter. No voltage converter is necessary for standard electronics.

China
220V · 50Hz
China uses three outlet types: Type A (two flat pins, like the US), Type C (two round pins, like Europe), and Type I (three angled pins, like Australia). Most modern Chinese outlets are multi-standard sockets that accept all three types simultaneously. If you are traveling from the US, your standard two-prong plug likely fits Chinese outlets without any adapter. Travelers from the UK and Australia need an adapter. China runs on 220V at 50Hz, so dual-voltage devices only need a plug adapter.

Italy
230V · 50Hz
Italy uses three outlet types: Type C (standard European two round pins), Type F (Schuko, two round pins with grounding), and Type L (three round pins in a line, uniquely Italian). Most travelers can get by with a standard European adapter, but the Italian Type L socket can cause confusion. Your phone and laptop chargers are dual voltage (100-240V) and only need a plug adapter. No converter is needed for standard electronics.

Spain
230V · 50Hz
Type C
Type FSpain uses Type C (two round pins, ungrounded) and Type F (Schuko, two round pins with grounding clips) outlets with 230V at 50Hz. This is the standard European system used across most of continental Europe. Travelers from the US, UK, Australia, and Japan need a travel adapter. European travelers with Type C devices can plug in directly. All modern phone and laptop chargers are dual voltage and only need a plug shape adapter.

Thailand
230V · 50Hz
Thailand uses a mix of Type A (two flat pins, US-style), Type B (two flat pins plus grounding, US-style), and Type C (two round pins, European-style) outlets with 230V at 50Hz. Many Thai outlets are multi-standard combo sockets that accept both flat and round pins. US and Japanese travelers often find their plugs fit directly. European Type C plugs also fit. UK and Australian travelers need an adapter. The critical detail: Thailand runs on 230V, so while US plugs may physically fit, you must verify your device is dual voltage (100-240V).

Portugal
230V · 50Hz
Type CType F Portugal uses Type C (two round pins, ungrounded Europlug) and Type F (Schuko, two round pins with grounding clips) outlets at 230V and 50Hz. This is the standard continental European system. Travelers from the US, UK, Ireland, Australia, or Japan need an adapter. Travelers from Spain, France, Germany, Netherlands, and most of mainland Europe can plug straight in. All modern phones, laptops, and camera chargers are dual voltage and only need a plug-shape adapter — no voltage converter required.
