Different countries use different electrical outlets. A travel adapter lets you plug your devices into foreign sockets. This guide covers plug types, voltage, and what to look for in an adapter.
Adapter vs Converter
Travel adapter: Changes the plug shape so it fits the socket. Does NOT convert voltage.
Voltage converter: Changes the electrical voltage. Rarely needed for modern electronics.
Most phone chargers, laptops, and camera chargers are “dual voltage” (100-240V) and only need an adapter, not a converter. Check the label on your charger – if it says “100-240V” you’re fine with just an adapter.
Common Plug Types
Type A/B (Americas, Japan): Two flat pins (A) or two flat plus ground pin (B). 120V.
Type C (Europlug): Two round pins. Used across Europe (except UK), South America, and Asia. 220-240V.
Type G (UK): Three rectangular pins. Used in UK, Ireland, Malaysia, Singapore. 230V.
Type I (Australia): Two angled flat pins plus ground. Used in Australia, New Zealand, China. 230V.

Some countries use multiple plug types. Hotels sometimes have “universal” outlets that accept several types.
What to Look For
USB ports: Adapters with USB-A and USB-C ports let you charge phones and tablets directly without needing your charger’s plug.
Multiple outlets: Some adapters have both a socket for your plug and USB ports.
Universal adapters: Work in multiple regions. Good for frequent travellers but bulkier than single-region adapters.
Surge protection: Protects devices from power spikes.
Compact size: Easier to pack.
Safety
- Don’t overload adapters with high-power appliances (hair dryers, kettles)
- Check your device’s voltage compatibility before plugging in
- Look for adapters with safety certifications (CE, FCC)
- Don’t use damaged adapters
