International Plug Types & Voltage Guide 2025

Plug anxiety is the top tech question I get. This guide maps plug types, voltage, and where you actually need a converter vs just an adapter. Country data is based on IEC standards and gov utility references updated for 2025.

Plug map & voltage quick view

• North America/Japan: Type A/B, 100–127V, 50/60Hz.
• EU (most): Type C/F, 220–240V, 50Hz.
• UK/HK/SG: Type G, 230V, 50Hz.
• Australia/NZ: Type I, 230V, 50Hz.
• India: Type C/D/M, 230V, 50Hz.
• Middle East: Mix of C/G; UAE is mostly G, Saudi uses G/C.

Adapter vs converter 101

• Adapters change plug shape only. Needed when prongs differ.
• Converters change voltage—rarely needed because most phones/laptops are dual voltage (100–240V). Check your charger label.
• Hair dryers/irons: Often single-voltage. Use hotel units or buy local to avoid blown circuits.

Regional cheatsheet

Europe (Schengen + UK)

• Type C/F for mainland; Type G for UK/IRL. Bring a universal adapter plus one Type G if you visit London.
• Voltage 230V—dual-voltage chargers are fine.

Asia

• Japan/Korea use 100–110V Type A/B; Southeast Asia mixes C/G/A. Thailand accepts A/B/C/F/G in many hotels.
• Carry a universal adapter; check hotel listing for “220V” before plugging US-only gear.

Middle East

• UAE/Oman: Type G. Qatar: G. Saudi: G/C mix. 230V.
• Pack surge protection; voltage spikes are more common per regional utility notices.

Oceania

• Australia/New Zealand: Type I, 230V. Fiji also Type I. Bring one adapter per traveler.

Africa & LATAM

• Africa varies: South Africa uses Type M; Morocco Type C; Kenya Type G. Verify with Plug Checker.
• Latin America often uses Type A/B and 110–127V; Brazil mixes Type N and 127/220V—check hotel listing.

Safety rules

• Use surge protection when charging laptops/cameras in 220V regions.
• Never use a high-wattage US hair dryer on 220V without a converter; better to use hotel dryers.
• For multi-device charging, use a single high-quality adapter + multiport charger to reduce load on loose wall sockets.

Adapters I recommend

Check your destination on Plug Checker before you pack. One good adapter plus a multiport charger beats carrying four cheap bricks.
