Travel Power Adapter Finder
Find power adapter plug type and voltage for any country.
Checks if your device is dual-voltage or needs a converter and lists the local plug standard.
Travel power adapter compatibility depends on three electrical specifications: voltage, frequency, and plug type. Using the wrong voltage can permanently damage your devices or create a fire hazard. Using the right adapter but wrong voltage converter leaves your device functioning but potentially overheating.
Power compatibility formula: Device is compatible if: Device Input Voltage Range includes Destination Voltage
Most modern devices (laptops, phone chargers, camera chargers) are dual-voltage (100–240V, 50/60Hz) — check the small print on the charger or device power supply label.
Step-down transformer required when: Destination Voltage > Device Max Voltage e.g., US device (120V max) in Europe (230V) without transformer = destroyed device
Wattage formula for converter sizing: Required Converter Watts ≥ Device Wattage × 1.25 (25% safety margin for surge capacity)
Device wattage formula: Wattage = Voltage × Amperage (W = V × A)
World voltage and frequency standards:
- 120V / 60Hz: USA, Canada, Mexico, some of Caribbean and Japan
- 230V / 50Hz: Europe, UK, Australia, most of Asia, Africa, Middle East
- 100V / 50Hz: Japan (unique: some 110V devices may not work at full efficiency)
Plug type reference:
- Type A (2 flat blades): USA, Canada, Mexico, Japan
- Type B (2 flat + 1 round): USA, Canada, Mexico
- Type C (2 round pins): Most of Europe, South America, Asia, Africa
- Type G (3 square pins): UK, Ireland, Hong Kong, Singapore, Malaysia
- Type I (2 flat angled): Australia, New Zealand, Argentina, China
What each variable means:
- Adapter (plug adapter): only changes the plug shape; does NOT convert voltage. Safe only for dual-voltage devices.
- Voltage converter/transformer: actually converts the voltage. Required for single-voltage devices.
- Universal adapter: covers multiple plug types; still does NOT convert voltage.
Worked example: US laptop charger: 100–240V, 50/60Hz, 65W. Traveling to Germany (230V/50Hz, Type C plugs).
Voltage check: 100–240V input — Germany’s 230V is within range. ✓ Frequency check: 50/60Hz — Germany’s 50Hz is within range. ✓ Plug type: US Type A → need Type A to Type C adapter (no converter needed)
Adapter cost: $5–$15. Converter cost: $25–$80 (not needed here). Packing just a plug adapter is sufficient and safe.
